Erectile dysfunction: A sign of heart disease?

Heart health and erectile function share several important connections. Understanding these connections may help you recognize the symptoms of cardiovascular disease sooner — and improve your chances of maintaining your sexual ability.

Atherosclerosis. This damaging process, which reduces blood flow to your heart and contributes to coronary artery disease, could also affect the blood vessels to the penis, keeping you from sustaining an erection. Conversely, if you're having trouble with erections, it could be a sign that your heart is also at risk.

Medications. Some prescriptions that men take to protect their hearts can cause erectile dysfunction. Additionally, medications that are often prescribed for erectile dysfunction may not be safe when combined with certain heart medications.

Anxiety and depression. Erectile dysfunction itself can be a significant source of anxiety for men. Add to that a fear that sexual activity could cause a heart attack, and your love life could take a plunge. Depression frequently affects men with heart disease. Both the condition itself and some of the medications used to treat it can lead to erectile dysfunction.

Atherosclerosis: Where erectile dysfunction and heart disease meet

If atherosclerosis has made your coronary arteries narrow and stiff, that means arteries elsewhere in your body are probably also affected. Atherosclerosis can prevent enough blood flow from reaching your heart, legs, brain and penis. When atherosclerosis affects blood flow to your penis, the blood can't sufficiently fill the penis to allow a suitable erection.

In one study, 64 percent of men who'd had heart attacks had erectile dysfunction before they knew they had cardiovascular disease. Some experts suggest that if you haven't been diagnosed with heart problems, consider erectile dysfunction a wake up call. It could be a warning sign that the blood vessels feeding your heart might also be in trouble.

The same factors that raise your risk of atherosclerosis in the arteries in your penis also increase your chances of coronary artery disease. Because the arteries supplying your penis are smaller than the ones to your heart, symptoms may first show up as erectile dysfunction.

Risk factors for cardiovascular disease and can contribute to erectile dysfunction include:

Diabetes. Men who have diabetes have more problems getting an erection than do men who don't have diabetes. The problem is partially due to the diabetes-related damage to blood vessels that supply the penis.

Obesity. Overweight men are more likely to have erectile dysfunction.

High cholesterol. A high level of low-density lipoprotein (LDL, or "bad") cholesterol contributes to atherosclerosis in blood vessels, raising the risk of erectile dysfunction.

Smoking. Smoking cigarettes raises your risk of developing atherosclerosis. Not only does smoking increase your chances of heart disease, but it can make you nearly twice as likely to develop erectile dysfunction.

High blood pressure. Over time, high blood pressure damages the lining of your arteries and accelerates the process of atherosclerosis — which can lead to cardiovascular disease and erectile dysfunction. [CLICK HER FOR ENTIRE ARTICLE]

Newswise: Who Gets Heart Failure? Race Takes Back Seat to Diabetes and High Blood Pressure

Newswise — Diabetes and high blood pressure, two conditions rooted in genetics and environmental surroundings, play a much greater role than race alone in determining who is mostly likely to develop heart failure, according to the latest study from cardiologists at Johns Hopkins. Each year, nearly 300,000 Americans die from heart failure.

Experts say that racial disparities have long been known to exist in who actually develops risk factors for the condition, with African Americans nearly twice as likely to be diagnosed with diabetes and more than a third as likely to have high blood pressure than Caucasian Americans. But researchers have only now determined the precise role played by race in comparison to other risk factors, including socio-economic factors, age, gender, smoking, family history, and other health problems, as well as diabetes and hypertension.

The Hopkins team will present its findings March 27 in New Orleans at the American College of Cardiology’s annual Scientific Sessions in New Orleans.

In the study, researchers monitored nearly 7,000 men and women, age 45 to 84, of different ethnic backgrounds and with no existing symptoms of heart disease. African Americans developed heart failure at significantly higher rates (4.6 cases per 1,000 per year) than all other races, including Hispanics and Caucasians. Their rate was almost five times that of Chinese Americans (1 case per 1,000 per year) and almost twice that of Caucasians (2.4 cases per 1,000 per year).

However, these apparent risk differences among races almost disappeared (dropping from twice as likely, a significant difference, to no more than one-and-a-half times as likely, an insignificant difference) when researchers used statistical techniques to exclude the two traditional risk factors for heart disease.

“When all major factors are taken into account, the differences between races for heart failure largely evaporate in the absence of diabetes and hypertension among African Americans,” says senior study investigator João Lima, M.D.

According to Lima, an associate professor of medicine and radiology at The Johns Hopkins University School of Medicine and its Heart Institute, these early results add to other interesting findings from the so-called Multiethnic Study of Atherosclerosis (MESA).
The study, started in 2001, is monitoring its ethnically diverse participants for six to eight years to see who develops heart failure and who does not. It is the first large-scale analysis of racial or ethnic differences in heart function. So far, 79 study participants have developed congestive heart failure.

Other results presented at the meeting showed differences among races in heart strain, or contraction, which may contribute to disparities in heart failure, albeit to a lesser extent. Indeed, African American hearts were found to contract less strongly than those of Hispanic, Caucasian or Chinese American backgrounds.

Lima cautions, however, that much remains to be understood about the root causes of racial disparities and how to fix them.

He points out that while African Americans are at much higher risk of heart failure, there is no similarly higher number for risk of suffering heart attack, which, like diabetes and hypertension, often leads to heart failure.

In MESA, researchers found a reverse relationship, with African Americans having the lowest rates of heart failure due to myocardial infarct (at 25 percent), while other races had a much higher proportion: Caucasians (40 percent), Hispanics (42 percent), and Chinese Americans (100 percent.)

Lima says the difference could be due to successful disease prevention efforts among all racial groups, except for African Americans, at controlling hypertension.

“A lot of public health attention has already been paid to getting high blood pressure under control, so it may be just that this risk factor is under tighter control in some ethnic groups than in others,” he says. “African Americans are clearly getting heart failure from causes other than heart attack.”

According to lead researcher Hossein Bahrami, M.D., M.P.H., the message to physicians is clear, “warding off heart failure in African Americans requires aggressive treatment of diabetes and hypertension. Whether through increased screening or greater emphasis on drug therapies, these are two risk factors that must be brought under control.”

Bahrami, a senior cardiology research fellow at Hopkins, says removing barriers for African Americans to controlling their diabetes and hypertension could be critical to reducing new cases of heart failure. Across all ethnic groups, an estimated 550,000 Americans are diagnosed each year.

Bahrami says the team’s next steps are to determine why different rates exist for these risk factors and the role played by biological and environmental factors. Funding for this study, which is taking place in six centers in the United States, comes from the National Heart, Lung and Blood Institute, a member of the National Institutes of Health.

Besides Lima and Bahrami, another Hopkins investigator involved in this study was David Bluemke, M.D., Ph.D. Study co-authors were Richard Kronmal, Ph.D., from the University of Washington in Seattle; Kiang Liu, Ph.D., from Northwestern University in Chicago, and Gregory L. Burke, M.D., M.S., from Wake Forest University in Winston-Salem, N.C.

Fend off heart disease with fish.

Good-for-You Fish
The Greenland Inuit eat an incredibly high-fat diet with few vegetables, yet their rate of heart disease is stunningly low. Chalk it up to all the fatty fish they eat: The staple food in their diet is fish rich in omega-3 fatty acids. You've probably heard by now that omega-3s fend off heart disease -- something that could be right around the corner if your blood sugar is stuck in overdrive. It's no wonder fish makes our list of Magic foods.

A study at the Harvard School of Public Health found that women with diabetes who ate fish just once a week had a 40 percent lower risk of dying from heart disease than did women with diabetes who ate fish less than once a month.

But omega-3s do more than protect your heart. They also quell inflammation in the body, a major contributor to numerous chronic diseases of aging, including insulin resistance and diabetes. It may even play a role in brain diseases such as Alzheimer's as well as certain cancers.

Of course, fish is also a protein food, and protein foods have virtually no impact on blood sugar. We suggest that you aim to eat fish for dinner once or twice a week when you might otherwise have chicken or beef. Make it baked, broiled, pan-fried, stewed, or grilled. Just don't make it fast food or deep fried, like fish and chips or a fish sandwich. Loaded with bad-for-you fats, this fare just isn't the same kettle of fish. One study found eating fried fish and fish sandwiches offered no heart benefits at all.

All fish contain some omega-3s, but fatty types such as albacore tuna, salmon, mackerel, lake trout, herring, and sardines are richest in them.

Health Bonus
While the strongest proof of the health benefits of fish points to the heart, there's also plenty of research showing that food with fins can cut the risk of prostate cancer and help maintain brain power as you age. There's also evidence that fatty fish may help defend against depression.

Study: Aspirin May Lower Risk Of Death In Women

(CBS News) CHICAGO Aspirin in low-to-moderate doses may lower the risk of death in women, particularly those who are older and prone to heart disease, a 24-year study of nearly 80,000 women suggests.

However, experts cautioned that the results are not definitive and that women shouldn't take aspirin as a health preventive without talking to their doctor.

In this long-running study of nurses who were middle-aged and older, women who took aspirin had a 25 percent lower risk of death compared to those who never took it. Aspirin-takers had a 38 percent lower risk of death from cardiovascular disease and a 12 percent lower risk of death from cancer.

Many doctors advise people who've had heart attacks and strokes to take a daily 81-milligram baby aspirin, costing less than 50 cents a week. The new study suggests aspirin may help healthy women, too.

No benefit was found for high doses, which the study defined as two or more standard 325-milligram aspirin tablets a day.

"This confirms what we already know: Aspirin is good for you, whether you're a man, whether you're a woman," said Dr. Jeffrey Berger of Duke University Medical Center who studies aspirin's effects. He was not involved in the new research and receives no money from aspirin makers.

However, since aspirin can cause ulcers and bleeding, Berger said, women should talk to their doctors before taking it to prevent disease.

"It's not a little vitamin; it's not a sugar pill," he said....[MORE]

HEART FELT -- Kastan Fills Emotional Gaps for Women With Heart Disease
By Mary Powers / powers@commercialappealcom

She never smoked.

She wasn't overweight.

Her blood pressure was normal.

She exercised regularly.

But at age 41, Kathy Kastan of Cordova started having symptoms of heart disease.

It would take two years, visits to two Memphis heart specialists and a trip to the Mayo Clinic in Rochester, Minn., to get the correct diagnosis and relief from crippling chest pain. Before it was over, she'd undergo five heart procedures plus emergency heart bypass surgery.

During her search for information, she found plenty of books about how to prevent or reverse heart disease. Most were written by physicians. None addressed the emotional roller coaster she was riding.

So she wrote that book.

"From the Heart: A Woman's Guide to Living Well with Heart Disease" is what she was looking for when she was diagnosed. Its official publication date is Sunday, but the book ($25, Da Capo Press) is in book stores now.

"I would have realized I'm not alone," Kastan said, explaining how the information would have helped her. "I would have felt more hopeful. I would have had something to direct me in a positive way and help me understand why I was floundering."

Instead of the physiology of atherosclerosis, in "From the Heart," Kastan writes about body image and sex. Instead of low-fat meal ideas, she details her own struggle to digest the diagnosis.

Along with strategies for navigating the health system, Kastan outlines the healing power of activism.

Kastan, whose father and husband are both physicians, is a licensed clinical social worker who had worked as a psychotherapist before her diagnosis. She now devotes herself full time to advocacy.

She is in her second term as president of WomenHeart, a national coalition for women with heart disease. She's also chairwoman of the American Heart Association's northwest region. In 2005, Kastan and the the foot-long bypass scar bisecting her chest were featured in a national public-awareness campaign about women and heart disease.

It's work that has her traveling, sometimes several times a month, lobbying elected and government officials or speaking to medical, consumer and other groups. She talks about the still under- appreciated risk heart disease poses to women as well as the need for more research about women and heart disease.

Her message to doctors: Take seriously female patients and their heart disease risk. Although she said more research and education are needed, she is hopeful. "We are getting there. We are moving in the right direction," she said.

She got serious about writing the book three years ago after surveying WomenHeart members. What they told her about their experiences with heart disease reinforced her belief that her story wasn't unique.

Kastan had a family history of heart disease and elevated cholesterol, but she wasn't considered an obvious candidate for the problem.

So when her left arm would tingle during a swim or a bike ride left her short of breath and nauseated, she blamed her age and asthma.

The first doctor blamed a leaky heart valve. The next one found a blockage in one of the main arteries supplying blood to her heart and vasospasm, a cramping of the blood vessel that temporarily reduced or halted its blood supply. But it took a trip to the Mayo Clinic's women's heart clinic before more aggressive treatment of the vasospasm brought symptom relief....[MORE]

Bloomberg.com: AtheroGenics Drug That Failed in Study Cuts Diabetes (Update2)

March 27 (Bloomberg) -- AtheroGenics Inc.'s experimental heart drug, which failed to meet a primary study goal last week, reduces diabetes and deaths from heart disease and should be developed, doctors said. Shares soared as much as 26 percent.

The medication, an anti-inflammatory known as AGI-1067, lowered deaths from heart attacks, cardiac arrest and strokes by 19 percent in the study, details of which were presented at the American College of Cardiology meeting in New Orleans. It cut by 64 percent the number of patients diagnosed with diabetes.

The study was initially designed to measure effectiveness against a range of complications, including chest pain. AtheroGenics reported last week that the medicine failed to meet the wider goal, though details weren't available. Doctors now say the drug should be developed because of how it works individually against deaths, heart attacks and diabetes.

The results ``are very encouraging and suggest that the drug is having a beneficial effect,'' said Steven Nissen, president of the cardiology group and chairman of cardiology at the Cleveland Clinic, in an interview. ``Someone should pursue further development of this drug.''

AtheroGenics' stock rose 17 cents, or 4.8 percent, to $3.75 at 11:14 a.m. New York time in Nasdaq Stock Market composite trading, after touching $4.54 earlier. The stock plunged 61 percent last week after the company first announced the trial failed to meet its primary goal, trading low as $2.83.

Marketing Agreement
London-based AstraZeneca Plc has a marketing agreement with AtheroGenics to develop AGI-1067 that could be worth as much as $1 billion if the drug completes development and hits sales goals. AstraZeneca hasn't yet told AtheroGenics if it plans to continue working with them on the product, said Russell Medford, Chief Executive Officer of AtheroGenics, in an interview today.

AGI-1067 is designed to counter the buildup of plaque in the arteries that occurs in 16 million Americans. More than 6,000 patients in the U.S., U.K., Canada and South Africa took part in the phase III study, the last stage generally required for regulatory approval.

Patients in the study were already getting drug therapy for the year following a heart attack or sudden on-set of chest pain, suggesting that the new medication may provide additional benefit beyond the current standard of care, researchers said.

Heart disease is the leading cause of death worldwide and kills 700,000 people in the U.S. each year, according to government statistics. The drug is the first in a new class that aims to treat heart disease by fighting inflammation.

Additional studies are needed to confirm the benefits and ensure the drug is safe. Patients getting AGI-1067 were more likely to be hospitalized for heart failure and develop diarrhea in the study.

There were also signs that the drug might affect liver function. One patient developed liver failure and recovered after the drug was halted.

Associated Press: Jurors side with Merck in Illinois Vioxx trial
Drug maker cleared over 2003 heart-attack death

EDWARDSVILLE, Illinois - Jurors in the Midwest's first trial over the once-blockbuster painkiller Vioxx on Tuesday cleared the drug's maker in the 2003 deadly heart attack of an obese 52-year-old woman.

The jury deliberated over two days before siding with Merck & Co., which had argued that Patty Schwaller's obesity and other health issues might have posed risks that better explain her collapse and sudden death.

Schwaller had taken Vioxx for about 20 months. Her husband claimed that Vioxx contributed to his wife's death and that Merck failed to sufficiently warn consumers that the drug increased the risk of cardiovascular problems.

The victory was Merck's 10th in 15 cases that have been tried in the mushrooming litigation over the drug Merck pulled off the market in 2004 after its research showed it increased the risk of heart attacks and strokes.

During the monthlong trial, Merck lawyers insisted that Patty Schwaller had several risk factors for heart disease, including obesity, diabetes, high blood pressure and a sedentary lifestyle.

The 5-foot-2 woman's weight fluctuated between 250 pounds and 300 pounds for roughly two decades before her death, attorneys have acknowledged.

But attorneys for Schwaller's widower, Frank Schwaller, pressed that the woman had no heart attacks, strokes or symptoms of congestive heart disease before her fatal collapse, fueling their belief that Vioxx contributed to her demise....[MORE]

Telephone-Based Psychotherapy Shows Durability in Depression - CME Teaching Brief® - MedPage Today

SEATTLE, March 22 -- For depressed patients on medication but too sad to seek psychotherapy as well, lasting help may be available by phone researchers found in a follow-up study.

For more than 75% of nearly 400 patients, the positive effects of six months of brief telephone psychotherapy at the start of antidepressant medication endured for 18 months after the first session, including six months beyond the end of all phone therapy, said Evette Ludman, Ph.D., of the Group Health Cooperative Center for Health Studies here, and colleagues.

This study, reported by Dr. Ludman and colleagues in the April issue of the Journal of Consulting and Clinical Psychology, was a follow-up to a 2004 report on the same sample of 393 patients, published in the Journal of the American Medical Association.

The follow-up found that at 18 months, 77% of those given phone-based therapy reported that depression was "much" or "very much" improved, compared with only 63% of those receiving usual care.

In the 18-month analysis, the benefits of telephone psychotherapy in the first six months were sustained during the second six months when only brief booster sessions were provided. Significantly a "robust clinical benefit" endured for six months after all treatment contact was discontinued, the researchers found.

"As with weight control," Dr. Ludman said, "maintaining improvement is the hardest part of treating depression."

Traditional in-person psychotherapy has limited reach among the large number of patients beginning antidepressant treatment in primary care, the researchers wrote. Expanding access to therapy calls for considering new therapy approaches, such as phone-based sessions, that place greater emphasis on accessibility, outreach, and patient convenience, the investigators concluded.

Of the participants, 195 were randomly assigned to antidepressant medication and usual care while 198 got medication and phone therapy. Of these, 348 (89%) completed the six-month blinded assessment, and 334 (85%) completed the 18-month follow-up.

On average, all patients reported a moderate level of depressive symptoms at baseline, two to four weeks after starting antidepressants prescribed by a primary-care provider.

Phone psychotherapy sessions, delivered by masters-level therapists, included eight core sessions (about 30 minutes) during the first six months, with 15- to 20-minute booster sessions every two months up to a year. After that, phone therapy ended.

According to a structured cognitive behavioral-based psychotherapy program, patients were encouraged to identify and counter their negative thoughts (cognitive behavioral therapy), pursue activities they had enjoyed in the past, and develop a plan to care for themselves....[MORE]

Knowing Cholesterol, Blood Pressure Numbers Can Save Lives

If one of your New Year's resolutions was to get healthier, then 'knowing your numbers' is a good way to start.

Andre Stanley decided to visit his doctor to get his health back on track for the new year. One of the first things she told him was to get to know his numbers.

"When she told me about the numbers, that they were very important based on my size," says Stanley. When I came here to her, I didn't know anything about numbers at all, O was just lost."

Stanley's physician, cardiologist Dr. Patricia Davidson says it's no longer acceptable to just know your total cholesterol level. Now you also need to know your HDL, LDL and triglycerides numbers.

"I know practically no one that will walk in my office and tell me they know what their numbers are," says Dr. Davidson, "It's a difference between life and death."

Doctors have long believed that people with a low total cholesterol level, under 150, are less likely to have heart attacks. But recent studies show that the HDL, or the good cholesterol, levels might be the key to good heart health.

A low HDL level can predict heart problems, especially if there's a family history of heart disease.

"It's very sensitive in the female population," says Dr. Davidson. "If women tend to have low good cholesterol levels they have a much higher risk of heart disease than that of the male population."

Health experts say knowing your blood pressure number can be important, too. Untreated high blood pressure can lead to health problems such as stroke, heart attack, damage to the eyes, kidney failure, and hardening of the arteries.

"So optimal blood pressure is under 120 and under 80 and if you can achieve that, there is a very small likelihood that you will have a heart attack or a stroke as a result of high blood pressure," says Dr. Davidson.

Dr. Davidson says it's important to know your numbers, and have them checked regularly, because they're measurements that can help you live a longer, healthier life.

"You need to participate in your care," says Dr. Davidson. "You know 911, that's the one number that will save your life, and so will your cholesterol numbers, your HDL or triglycerides, your LDL, your blood pressure, those are numbers that will save your life."

CME Teaching Brief® - MedPage Today - Strokes Stop Essential Brain Crosstalk

ST. LOUIS, March 14 -- Spatial neglect -- a common attention-deficit sequel to stroke -- appears to be caused by a lack of communication between two regions of the brain, according to researchers here.

The finding contradicts the traditional explanation that spatial neglect is caused by damage to a specific brain region, said Maurizio Corbetta, M.D., of Washington University.

Instead, magnetic resonance imaging showed that patients with neglect -- in which patients have difficulty paying attention to one side of their bodies or the visual field -- have disrupted connections between dorsal and ventral frontoparietal attention networks, reported Dr. Corbetta and colleagues in the March 15 issue of Neuron.

"For more than a century, we have linked neurological deficits and their recovery to the damage done to neurons directly affected by a stroke or other injury," Dr. Corbetta said in a statement. ...[MORE]

CME Teaching Brief® - MedPage Today - FDA Warns of Sedative-Aided Sleep Driving and Anaphylaxis

ROCKVILLE, Md., March 14 -- The FDA has taken steps to ensure that clinicians and patients are aware of rare bizarre effects associated with sedative hypnotics, including driving or eating while sleeping.

The agency has ordered makers of all sedative-hypnotic drugs to strengthen label warnings about the risk of "complex sleep-related behaviors" and also severe allergic reactions. The FDA defined sleep driving as "driving while not fully awake after ingestion of a sedative-hypnotic product, with no memory of the event."

Last December, the FDA sent letters to manufacturers of products approved for the treatment of sleep disorders requesting that the whole class of drugs revise product labeling to include warnings about the following potential adverse events:

Anaphylaxis and severe facial angioedema, which can occur the first time the product is taken. Complex sleep-related behaviors which may include sleep-driving, making phone calls, and preparing and eating food while asleep.

"There are a number of prescription sleep aids available that are well-tolerated and effective for many people," said Steven Galson, M.D., MPH, director of FDA's Center for Drug Evaluation and Research. "However, after reviewing the available post-marketing adverse event information for these products, the FDA concluded that labeling changes are necessary to inform health care providers and consumers about risks."

Russell Katz, M.D., director of the FDA's division of neurology products at the center, said the new label will warn that a number of complex-sleep related behaviors "including cooking and eating, using the telephone, having sex, and driving" have been reported by persons using the drugs. Typically, the patient has no memory of these actions.

At a press briefing today, Dr. Katz repeatedly emphasized that the allergic reactions, including anaphylaxis and angioedema, and the complex sleep-related behaviors,"are rare by any definition" and he said the FDA has not received any reports of death associated with either side effect....[MORE]

USA Today: Stay calm, or you may calcify your arteries: CLICK HERE FOR MORE

Older adults with explosive tempers are more likely than mellow people the same age to have calcium deposits in their coronary arteries, a key sign of high risk for heart attack, a study reported Wednesday.

The more likely someone over 50 expresses anger by lashing out, the more calcification shows up in his coronary arteries, researchers from Washington State University say. They reported their findings at the American Psychosomatic Society meeting in Budapest.

At the start, 185 participants filled out questionnaires on how they dealt with anger. Researchers used electron beam computerized tomography (EBCT) to measure the calcium deposits in arteries. Nine years later, everyone's arteries were scanned again....

Radiation for breast cancer ups heart disease risk: CLICK HERE FOR MORE
POSTED: 9:27 p.m. EST, March 7, 2007

NEW YORK (Reuters) -- As a treatment for breast cancer, radiation, even modern regimens, appears to increase the risk of cardiovascular disease, according to a report in the Journal of the National Cancer Institute.

Earlier reports have indicated that radiotherapy regimens used in the 1970s elevate heart disease risk, but it has been less clear whether more recent regimens also increase the risk.
Apart from the "clear benefits" of radiotherapy, doctors should still be aware of the potentially increased risk of cardiovascular disease following specific radiotherapy regimens in long-term breast cancer survivors, Dr. Flora E. van Leeuwen, from the Netherlands Cancer Institute in Amsterdam, and colleagues note in the report....

Should Everyone Be on a Statin? CLICK HERE FOR MORE
Posted 03/06/2007
Charles P. Vega, MD, FAAFP

Summary and Viewpoint
Statins have become some of the most popular medications prescribed in primary care offices, and for good reason. In a meta-analysis involving 25 studies enrolling 69,511 individuals with a history of coronary heart disease, statin therapy reduced the rate of coronary heart disease mortality or nonfatal myocardial infarction by 25% and reduced all-cause mortality by 16%.[1] The beneficial effects of statins in this meta-analysis were evident in both sexes and among older adults, and statins improved outcomes regardless of baseline levels of low-density lipoprotein (LDL) cholesterol.

The record of cholesterol-lowering therapy in improving outcomes among patients without a prior history of cardiovascular disease is less strong. A previous meta-analysis examining all cholesterol-lowering medications in the primary prevention of cardiovascular events and death found a reduction in the rate of coronary heart disease events of 30%.[2] However, the mortality rate was unaffected by the use of cholesterol-lowering medications, and when the authors examined trials of statins alone, these medications failed to reduce rates of coronary heart disease or mortality....

The Food and Drug Administration has approved expanded use of Pfizer Inc.'s blockbuster cholesterol-lowering medicine Lipitor by five new categories, including one to reduce the risk of non-fatal heart attacks and strokes, the company said Wednesday.

The expanded label for the world's top-selling prescription drug will also include its approval for use in reducing the risks of certain types of heart surgery, hospitalization for heart failure and chest pain in patients with heart disease.

Pfizer said Lipitor was the first cholesterol-lowering drug to win approval for reducing risk of hospitalization for heart failure.

The expanded label may provide Pfizer sales representatives with new ammunition in the battle to stem market erosion as health plans turn up the pressure to switch patients to much less expensive generic versions of Merck & Co.'s Zocor....

The Heart Of Diabetes Encourages People to Control Type 2 Diabetes

HOUSTON, March 8 /PRNewswire/ -- Walt "Clyde" Frazier knows the
importance of good health goes beyond the basketball court. At the peak of
his professional basketball career in the 1970s, he kept a work-out
routine, had regular check-ups and paid close attention to his overall
health. Now, almost 40 years later, Frazier continues to maintain a healthy
lifestyle because a healthy future means more to him than ever.

It is also important to Frazier that others learn how to have a healthy
future, which is why he is teaming up with the American Heart Association's
The Heart Of Diabetes(SM): Understanding Insulin Resistance national
campaign. The goal of the program is to educate people who live with type 2
diabetes about their increased risk of cardiovascular disease (CVD) because
adults with diabetes have heart disease death rates that are approximately
two to four times higher than adults without diabetes. In fact, at least 65
percent of people with diabetes die from some form of heart disease and
stroke.

Frazier has a family history of type 2 diabetes, obesity and CVD. The
Heart Of Diabetes program offers participants a family history tool that
helps them track blood relatives who have or had diabetes or associated
cardiovascular diseases....

Kidney Disease Opens Door to Heart Disease, Other Leading Killers, Says National Survey: CLICK HERE FOR MORE
National Kidney Foundation program demonstrates value of simple tests to
diagnose kidney disease in people who are most at risk

NEW YORK, March 8 /PRNewswire/ -- People with chronic kidney disease are significantly more likely to have other, life-threatening conditions
such as heart disease, according to new findings from a nationwide
screening program by the National Kidney Foundation (NKF) published in the
March issue of the American Journal of Kidney Diseases. The report is
released today in conjunction with the 2nd annual "World Kidney Day"
observance in recognition of the worldwide significance of kidney disease
as a public health problem.

In the survey of people at risk of developing kidney problems, those
who were already diagnosed with Chronic Kidney Disease, or CKD, were also
at increased risk of having poorly controlled blood sugar, a hallmark of
diabetes. Compared to the general population, people at risk of CKD were
more likely to be overweight, and have high blood pressure. The survey was
conducted through NKF's Kidney Early Evaluation Program (KEEP), a free
kidney health detection program designed to help people at risk for chronic
kidney disease (CKD) receive early diagnosis and treatment.

"People at risk of CKD are more than twice as likely as people who are
not at risk to have high blood pressure," says Allan Collins, MD, president
of the NKF. "Among people at risk, 27% of those already diagnosed with CKD
have heart disease, the nation's top killer, relative to only 15% of people
at risk of, but not yet diagnosed with, kidney problems," he adds. "These
findings suggest that CKD can multiply the risk of other devastating
illnesses, demonstrating the importance of diagnosing and managing the
disease in those who are most vulnerable."...

How to tell if you're having a heart attack, and what to do next
Is it a heart attack? A guide
Date published: 1/28/2007

Heart disease is the leading cause of death in the United States, and heart attack, the sudden blockage of blood flow to the heart, is one way that heart disease reveals itself.

Each year about 1.2 million Americans suffer a heart attack. If you become one of them, here's some information that could save your life.

Is it a heart attack?
The first thing that a person having a heart attack must do is acknowledge that it's happening, said Lisa Lucas, director of cardiac services for Mary Washington Hospital.

"They delay a lot," Lucas said. "It's hard for them to imagine that they're having a heart attack. When they realize that they need to go to the emergency room, it's hours and hours after they've had this pain."

This admission is even more critical for those at increased risk of heart attack, such as those who smoke or have diabetes, hypertension or a family history of heart disease.

So how do you recognize a heart attack? There are a couple of important indicators, Lucas said.

Pressure in the chest: With most heart attacks, there is an uncomfortable pressure, squeezing, fullness or pain in the center of the chest.

"It could be a heaviness, a pressure, radiating down one of their arms," Lucas said.

Discomfort in other areas: Symptoms also can include pain that moves to the back, neck, jaw or stomach. Shortness of breath that lasts for more than a few seconds is common, as are sweating, nausea and lightheadedness.

Women's symptoms: Women can have some of the same symptoms as men, such as shortness of breath, nausea and back or jaw pain. But their symptoms are likely to be different.

"A common symptom that differs from men is 'lingering tiredness'," said Diana R. Louder, coordinator for cardiovascular research and community programs at Mary Washington. Women usually don't get the crushing "elephant sitting on your chest" symptom, Louder said.

"Women's symptoms are usually a little more vague," Lucas said. "Sometimes they can't describe it."

What to do: Call 911. Patients who call an ambulance can get treatment up to an hour sooner, compared with those who go to the hospital by car.

"They think the rescue squad is just a ride to the hospital, and it's not," Lucas said. "The rescue squad is central to the care you receive on the way."

Up to one-fourth of heart-attack patients die before reaching the hospital.

"Sudden death is a high probability for those patients when they wait at home," Lucas said. "If they're driving themselves, there's no way to provide emergency care on the way."

While waiting for the ambulance, the patient should chew one regular aspirin tablet

Los Angeles Times Brief: Depression drug aids heart patients
From Times wire reports
January 29, 2007

A drug can combat depression common among patients with severe heart disease, but psychological counseling doesn't seem to work, a study has found.

The report from the University of Montreal Hospital Center said there have been few studies looking at how much antidepressants help heart disease patients with depression, even though as many as 27% may suffer from it. Doctors believe that treating the depression may also slow the deterioration of patients' health.

The Canadian study, published in the Jan. 25 issue of the Journal of the American Medical Assn., involved 284 patients variously given the drug citalopram — sold as Celexa — a placebo or short-term psychotherapy. The patients had previously suffered a heart attack or major blockage of arteries.

Citalopram is one of a class of antidepressants called SSRIs.

The study found that the drug worked to combat depression by easing its most common symptoms, with the effect apparent within six weeks. But, it concluded, counseling did not have an effect.

Victims of heart attacks, strokes need quick treatment
By: BRADLEY J. FIKES - Staff Writer

Someone's been hit by a car and is bleeding profusely. A child falls down a flight of stairs and is knocked unconscious.

Of course, you dial 911 immediately to get an ambulance.

But what if you feel prolonged pain and pressure in your chest? What if someone suddenly has trouble speaking, or becomes partially paralyzed? These, too, are life-threatening emergencies. And you need to dial those three numbers right away.

However, people aren't taking these warning signs of a heart attack or stroke seriously enough, says the American Heart Association and the local medical community.

Half of people who need emergency treatment are driving themselves or being driven to the hospital, said Shelley Berthiaume, quality improvement initiative director for the American Heart Association.

As a result, people die or become permanently injured who could make a full recovery ---- if they had been treated quickly.

If only they had made that call.

When to call
Medical emergencies that demand a 911 call include unconsciousness, heavy bleeding or very intense pain, said Dr. Mark Olcott, an urgent care physician with ScrippsHealth. But heart attack and stroke are the biggest concerns, Olcott said, because they are so common and the damage from delaying treatment can be so severe.

"We're assuring people not to be worried in the emergency room for using the system in the face of any of these conditions," Olcott said. Lesser matters, such as a sprain or a persistent cold or cough not accompanied by significant chest pain, are best treated at urgent care centers, he said.

Berthiaume said people may not want to think about being in a life-threatening situation.

"They may not want to admit that their lives could change forever," she said. But by delaying, they make matters worse.

Dennis Leahy, an interventional cardiologist at Palomar Medical Center in Escondido, said people can gauge the significance of their symptoms by taking into account their medical history.

For a 60-year-old male who is overweight and has a family history of heart disease, severe chest pains and shortness of breath should be considered a heart attack until proven otherwise, Olcott said. But in a 20-year-old man who has just completed a strenuous task, with no personal or family history of heart disease, those symptoms are probably harmless.

"You make it easier for us all if you came to us early," said Berthiaume, a registered nurse who was formerly a hospital coordinator at Palomar Medical Center.

Berthiaume helped Palomar comply with the heart association's Get With the Guidelines program to teach the most up-to-date medical-care methods for heart attack and stroke patients. Palomar Medical Center is the only hospital in San Diego or Riverside counties recognized for meeting the guidelines for two or more years. (MORE)

Expertise Essential for Coronary Intervention Without Surgical Backup - CME Teaching Brief® - MedPage Today

TEMPLE, Tex., Feb. 5 -- Only high-volume cardiac interventionalists with meticulous track records should consider performing percutaneous coronary procedures without onsite surgical backup, according to a consensus statement.

Without endorsing the use of such procedures without onsite surgical backup, the Society for Coronary Angiography and Interventions said that only cardiologists who perform a minimum of 100 interventions annually -- including at least 18 of them primary -- should be eligible to intervene without a surgical safety net.

Moreover, no cardiologists should begin working at such a facility until "they have a lifetime experience of more than 500 percutaneous coronary interventions as primary operator after completing fellowship."

Gregory J. Dehmer, M.D., of the Texas A & M School of Medicine, and SCAI president, said that by spelling out those requirements the society "has defined 'expert' interventionalist." Only experts, he said, should be working without a safety net.

The consensus statement was published in the February issue of Catheterization and Cardiovascular Interventions and a shorter version was published on the journal's website.
Although the SCAI statement sets forth minimum volume requirements, Dr. Dehmer said the statement gives equal emphasis to quality, noting that it recommends that free-standing percutaneous coronary intervention centers and interventionalists at those centers should also meet quality benchmarks.

Hypertension During Pregnancy Linked to Later Heart Disease - CME Teaching Brief® - MedPage Today

Although hypertension during pregnancy usually subsides after delivery, a postmenopausal second act may await, found researchers here.

The postmenopausal course of women with a history of hypertension during pregnancy may be marked by coronary calcification and an increased risk of coronary artery disease, said Michiel Bots, M.D., Ph.D., of the Julius Center for Health Sciences and Primary Care here, and colleagues.

They found women with mild elevations of blood pressure from preeclampsia had a 57% increased risk of coronary calcification several decades later compared with women who were normotensive during pregnancy, they reported in the February issue of Hypertension.

"To the best of our knowledge, the present study is the first to show that a history of high blood pressure during pregnancy is related to coronary calcification later in life," they said.

Many women who have had preeclampsia exhibit the phenotype of the metabolic syndrome and impaired endothelial function three to 12 months postpartum, the researchers said. In addition, preeclampsia is associated with an increased risk of cardiovascular events and death later in life.

The findings of this study are in line with these observations, they said, and expand the evidence to an increased risk of atherosclerosis, a significant predictor of subsequent cardiovascular disease and total mortality.

The study population included 491 healthy postmenopausal women selected from participants enrolled in the PROSPECT study from 1993 to 1997. PROSPECT was one of two Dutch cohorts participating in the European Prospective Investigation into Cancer and Nutrition (EPIC).

Information on high blood pressure during pregnancy was obtained by questionnaire. Of the women, 151 (30.7%) reported having had high blood pressure in pregnancy.

The high prevalence of hypertension was most likely the result of a definition of "hypertension during pregnancy" that included not only brief and modest elevations during pregnancy but also women with preeclampsia, the researchers said. Unfortunately, they added, blood pressure levels for women with nonproteinuric hypertension or mild elevations were not available. [MORE]

"PRESS RELEASE FROM JOHNS HOPKINS UNIVERSITY: CALL MADE FOR CHANGES IN WOMEN'S HEART DISEASE RISK-FACTOR LIST"
-- Family history and blood C-reactive protein should be added to traditional risk factors for all older women

Johns Hopkins cardiologists are calling for an expansion of the criteria widely used by physicians to detect and assess a postmenopausal woman's chances of developing cardiovascular disease, the leading cause of death among women in the United States.

In an editorial appearing in the Journal of the American Medical Association (JAMA) online Feb. 14, Roger Blumenthal, M.D., and colleagues say that a family history of heart disease and blood levels of a protein tied to vessel inflammation, C-reactive protein, should quickly be added to traditional assessments of women's risk of suffering a heart attack, stroke or severe chest pain (angina).

"Physicians should incorporate these factors into their testing and decision-making about which women are most likely to develop cardiovascular disease," says Blumenthal, an associate professor and director of the Ciccarone Preventive Cardiology Center at The Johns Hopkins University School of Medicine and its Heart Institute. "And physicians should intervene with lifestyle changes and drug treatment before symptoms start to appear," he adds. "Our best means of prevention is through early identification of those most at risk."

Blumenthal says these changes could help ameliorate the discrepancy between the death rate for men and women from cardiovascular disease, which has steadily declined for men over the last 20 years, but has remained relatively the same for women.

The new risk-factor list would strengthen existing assessment tools, including the Framingham Risk Estimate, which gauges how likely a person is to suffer a fatal or nonfatal heart attack within 10 years and calculates risk based on a summary score of such factors as age, blood pressure, cholesterol levels and smoking.

The Johns Hopkins experts base their editorial call on research conducted elsewhere and published in the same issue of JAMA, which looked at the predictive value of more than 35 risk factors not included in the Framingham score but reported to play a role in heart disease and stroke.

They found clear evidence that only family history and C-reactive protein, or hsCRP for short, had significant, additional predictive value in determining women really at moderate or high risk of future cardiovascular disease. The new method changed risk scores for at least 20 percent of the women studied.

"These are the best data yet to show how we should be assessing our female patients," says Blumenthal, whose own research showed in 2005 that the gold standard Framingham tool failed to identify approximately one-third of women over age 60 who had advanced hardening and narrowing of the arteries for their age and sex.

The latest findings are not surprising, the Johns Hopkins team says. Family history - where either a parent or a sibling suffered a coronary event - doubles a woman's own chances of arterial disease. High blood levels of C-reactive protein, in excess of 3 milligrams per liter, also double the risk. And the effects are multiplied if both factors are present, with a woman's risk rising almost fourfold.

Also in 2005, Blumenthal and his team suggested additional screening, using CT scans of the arteries and calcium scoring to better find women who would likely benefit from aspirin and statin therapy. Such additional tests, he says, should still be considered for those women with no symptoms and at least two traditional risk factors who are also undergoing lifelong drug therapy with aspirin and lipid-lowering drugs.

But, he notes, the latest analysis, which was funded by the Donald W. Reynolds Foundation, provides a thorough review of many potential risk factors and should be applied for all postmenopausal women. Results are available online at http://www.reynoldsriskscore.org/

Evaluation of the women in the current study included analysis of race, age, body mass index, menopause status, frequency of exercise, alcohol use, postmenopausal hormone use and dietary supplements of vitamin E, other multivitamins and aspirin. Blood factors studied were equally varied and included levels of homocysteine, creatinine, fibrinogen and hemogloblin A1C levels.

The information came from the U.S. Women's Health Study, which tracked for a decade more than 24,000 healthy women to see who developed coronary heart disease and who didn't. All women were over age 45.

"Our goal is to make heart attacks less likely to occur, and to do so by strongly considering therapies such as aspirin, cholesterol-lowering medications and, possibly, blood pressure medications for individuals at higher risk," says editorial co-author and cardiologist Erin Michos, M.D., a clinical fellow at Johns Hopkins.

In addition to researchers' call for change, Michos says that existing treatment guidelines, the 2001 National Cholesterol Education Program Adult Treatment Panel, which currently emphasize the Framingham score, should be revised to incorporate family history and hsCRP.

Air Pollution Linked to Increased Cardiovascular Events and Death in Postmenopausal Women - CME Teaching Brief® - MedPage Today

Fine-particulate air pollution over time significantly increased the risk of first heart attack or stroke, as well as cardiac mortality, in postmenopausal women, researchers here reported.

Moreover, the risk increased as pollution worsened so that for every 10 µg per cubic meter increase in fine-particulate matter the risk of a cardiovascular event rose by 24% and the risk of death jumped by 76%, found Kristin A.

NOTE: Due to its subject matter, some words in this release have been edited to avoid its being captured by spam filters

FOR IMMEDIATE RELEASE
18 MILLION U.S. MEN AFFECTED BY ER*CT*LE DYSFUNCTION
- Lifestyle Changes Could Improve Male Sexu*l Function
More than 18 million men in the United States over age 20 are affected by er*ct*le dysfunction, according to a study by researchers from the Johns Hopkins Bloomberg School of Public Health.
The prevalence of er*ct*le dysfunction was strongly linked with age, cardiovascular disease, diabetes and a lack of physical activity. The findings also indicate that lifestyle changes, such as increased physical activity and measures to prevent cardiovascular disease and diabetes, may also prevent decreased er*ct*le function. The study is published in the Feb. 1, 2007, issue of the American Journal of Medicine.

"Physicians should be aggressive in screening and managing middle-aged and older patients for er*ct*le dysfunction, especially among patients with diabetes or hypertension," said Elizabeth Selvin, PhD, MPH, lead author of the study and a faculty member in the Bloomberg School of Public Health's Department of Epidemiology. "The associations of er*ct*le dysfunction with diabetes and cardiovascular risk factors may serve as powerful motivators for men who need to make changes in their diet and lifestyle."

For the study, the research team analyzed data from 2,126 men who participated in the National Health and Nutrition Examination Survey (NHANES). Men who reported being "sometimes able" or "never able" to get and keep an er*ct*on were categorized as having er*ct*le dysfunction, while men who reported being "always or almost always able" or "usually able" were not.

The overall prevalence of er*ct*le dysfunction among men in the United States was 18 percent. Men aged 70 and older were much more likely to report having er*ct*le dysfunction compared to only 5 percent in men between the ages of 20 and 40. Nearly half of all men in the study with diabetes also had er*ct*le dysfunction. And, almost 90 percent of all men with er*ct*le dysfunction had at least one risk factor for cardiovascular disease, including diabetes, hypertension, having poor cholesterol levels or being a current smoker. Men with er*ct*le dysfunction were also less likely to have engaged in vigorous physical activity within the month prior to participation in the study.

Unhappy Meals

Eat food. Not too much. Mostly plants.

That, more or less, is the short answer to the supposedly incredibly complicated and confusing question of what we humans should eat in order to be maximally healthy. I hate to give away the game right here at the beginning of a long essay, and I confess that I’m tempted to complicate matters in the interest of keeping things going for a few thousand more words. I’ll try to resist but will go ahead and add a couple more details to flesh out the advice. Like: A little meat won’t kill you, though it’s better approached as a side dish than as a main. And you’re much better off eating whole fresh foods than processed food products. That’s what I mean by the recommendation to eat “food.” Once, food was all you could eat, but today there are lots of other edible foodlike substances in the supermarket. These novel products of food science often come in packages festooned with health claims, which brings me to a related rule of thumb: if you’re concerned about your health, you should probably avoid food products that make health claims. Why? Because a health claim on a food product is a good indication that it’s not really food, and food is what you want to eat.

Uh-oh. Things are suddenly sounding a little more complicated, aren’t they? Sorry. But that’s how it goes as soon as you try to get to the bottom of the whole vexing question of food and health. Before long, a dense cloud bank of confusion moves in. Sooner or later, everything solid you thought you knew about the links between diet and health gets blown away in the gust of the latest study.

Last winter came the news that a low-fat diet, long believed to protect against breast cancer, may do no such thing — this from the monumental, federally financed Women’s Health Initiative, which has also found no link between a low-fat diet and rates of coronary disease. The year before we learned that dietary fiber might not, as we had been confidently told, help prevent colon cancer. Just last fall two prestigious studies on omega-3 fats published at the same time presented us with strikingly different conclusions. While the Institute of Medicine stated that “it is uncertain how much these omega-3s contribute to improving health” (and they might do the opposite if you get them from mercury-contaminated fish), a Harvard study declared that simply by eating a couple of servings of fish each week (or by downing enough fish oil), you could cut your risk of dying from a heart attack by more than a third — a stunningly hopeful piece of news. It’s no wonder that omega-3 fatty acids are poised to become the oat bran of 2007, as food scientists micro-encapsulate fish oil and algae oil and blast them into such formerly all-terrestrial foods as bread and tortillas, milk and yogurt and cheese, all of which will soon, you can be sure, sprout fishy new health claims. (Remember the rule?)

By now you’re probably registering the cognitive dissonance of the supermarket shopper or science-section reader, as well as some nostalgia for the simplicity and solidity of the first few sentences of this essay. Which I’m still prepared to defend against the shifting winds of nutritional science and food-industry marketing. But before I do that, it might be useful to figure out how we arrived at our present state of nutritional confusion and anxiety.

The story of how the most basic questions about what to eat ever got so complicated reveals a great deal about the institutional imperatives of the food industry, nutritional science and — ahem — journalism, three parties that stand to gain much from widespread confusion surrounding what is, after all, the most elemental question an omnivore confronts. Humans deciding what to eat without expert help — something they have been doing with notable success since coming down out of the trees — is seriously unprofitable if you’re a food company, distinctly risky if you’re a nutritionist and just plain boring if you’re a newspaper editor or journalist. (Or, for that matter, an eater. Who wants to hear, yet again, “Eat more fruits and vegetables”?) And so, like a large gray fog, a great Conspiracy of Confusion has gathered around the simplest questions of nutrition — much to the advantage of everybody involved. Except perhaps the ostensible beneficiary of all this nutritional expertise and advice: us, and our health and happiness as eaters.

FROM FOODS TO NUTRIENTS

It was in the 1980s that food began disappearing from the American supermarket, gradually to be replaced by “nutrients,” which are not the same thing. Where once the familiar names of recognizable comestibles — things like eggs or breakfast cereal or cookies — claimed pride of place on the brightly colored packages crowding the aisles, now new terms like “fiber” and “cholesterol” and “saturated fat” rose to large-type prominence. More important than mere foods, the presence or absence of these invisible substances was now generally believed to confer health benefits on their eaters. Foods by comparison were coarse, old-fashioned and decidedly unscientific things — who could say what was in them, really? But nutrients — those chemical compounds and minerals in foods that nutritionists have deemed important to health — gleamed with the promise of scientific certainty; eat more of the right ones, fewer of the wrong, and you would live longer and avoid chronic diseases.

100 percent juices found as beneficial to health as fruits and vegetables

When it comes to some of today’s health issues, 100 percent fruit and vegetable juices do help reduce risk factors related to certain diseases.

This conclusion is the result of a European study designed to question traditional thinking that 100 percent juices play a less significant role in reducing risk for both cancer and cardiovascular disease than whole fruits and vegetables.

Juices are comparable in their ability to reduce risk compared to their whole fruit/vegetable counterparts say several researchers in the United Kingdom who conducted the literature review. The researchers analyzed a variety of studies that looked at risk reduction attributed to the effects of both fiber and antioxidants. As a result, they determined that the positive impact fruits and vegetables offer come not from just the fiber but also from antioxidants which are present in both juice and the whole fruit and vegetables.

This 2006 review of the literature states, “When considering cancer and coronary heart disease prevention, there is no evidence that pure fruit and vegetable juices are less beneficial than whole fruit and vegetables.” The researchers add that the positioning of juices as being nutritionally inferior to whole fruits and vegetables in relationship to chronic disease development is “unjustified” and that policies which suggest otherwise about fruit and vegetable juices should be re-examined.

The researchers who authored the paper “Can pure fruit and vegetable juices protect against cancer and cardiovascular disease, too? A review of the evidence” suggest that more studies in certain area are needed to bolster their findings. The study was published in the International Journal of Food Science and Nutrition (2006).

“Although this independent review of the literature is not designed to focus on any particular 100 percent juice, it does go a long way in demonstrating that fruit and vegetable juices do play an important role in reducing the risk of various diseases, especially cancer and cardiovascular heart disease,” says Sue Taylor, RD, with the Juice Products Association, a non-profit organization not associated with this research. She adds that appropriate amounts of juices should be included in the diet of both children and adults, following guidelines established by leading health authorities.

Taylor also points to a large epidemiological study, published in the September 2006 issue of the Journal of Medicine, which found that consumption of a variety of 100 percent fruit and vegetable juices was associated with a reduced risk for Alzheimer’s disease. In fact, that study found that individuals who drank three or more servings of fruit and vegetable juices per week had a 76 percent lower risk of developing Alzheimer’s disease than those who drank juice less than once per week.

News - New Therapy to Treat Patients With Severely Elevated Cholesterol Levels
PHILADELPHIA, PA -- January 11, 2007 -- Researchers at the University of Pennsylvania School of Medicine have demonstrated the potential of a new type of therapy for patients who suffer from high cholesterol levels.

The findings are in the January 11 issue of the New England Journal of Medicine (NEJM). In this study, patients with homozygous familial hypercholesterolemia (FH), a high-risk condition refractory to conventional therapy, had a remarkable 51% reduction in low-density lipoprotein (LDL) or "bad cholesterol" levels.

"Our study shows that targeted inhibition of the microsomal triglyceride transfer protein (MTP) is highly effective in reducing cholesterol levels in these very high risk patients," stated Daniel J. Rader, MD, Director of Preventive Cardiology and the Clinical and Translational Research Center at Penn, and principal investigator of this study. "Furthermore, there are many other patients who have cholesterol levels that are difficult to treat or who are not tolerant to treatment with statins. New therapies are required for these patients as well, and it is possible that after further research MTP inhibition could eventually be used for such patients."

Genetic defects in MTP lead to profoundly low levels of LDL. Using this information, Bristol-Myers Squibb began to search for inhibitors of this protein and discovered the study drug, originally known as BMS-201038. Bristol-Myers Squibb then donated it to Penn for use in clinical trials in patients with severe cholesterol problems. Rader and his team at Penn designed and carried out the current study in homozygous FH patients with support from the Doris Duke Charitable Foundation. Due to the success in this study, Penn has licensed the drug to Aegerion Pharmaceuticals Inc for further development as AEGR-733.

Patients who suffer from homozygous FH typically respond poorly to standard drug therapy and have a very high risk of premature cardiovascular disease.

Homozygous FH is caused by loss-of-function mutations in both alleles of the LDL receptor gene. It is a rare form of hypercholesterolemia affecting approximately one in every million people. Patients with this disorder typically have plasma cholesterol levels of more than 500 mg per deciliter. If untreated, patients develop cardiovascular disease before they are 20-years-old and generally do not live past the age of 30. Because existing cholesterol lowering drugs are relatively ineffective in this patient population, new therapies to reduce LDL levels are needed.

In this study, researchers conducted a dose-escalation study to examine the safety, tolerability and effects on lipid levels of an inhibitor of MTP in six patients with homozygous FH. Patients received the MTP inhibitor at four different doses, each for four weeks, and returned for a final visit after an additional four-week drug washout period. Analysis of lipid levels, safety laboratory analyses, and magnetic resonance imaging of the liver for hepatic fat content were performed throughout the study.

All patients tolerated titration to the highest dose studied. In addition to the 51% reduction in LDL cholesterol, treatment at this dose also decreased total cholesterol levels by 58%, triglyceride levels by 65% and apolipoprotein B levels by 56% from baseline. In contrast to statin drugs, which have relatively little effect on cholesterol levels in homozygous FH patients, the MTP inhibitor was shown to reduce the liver's ability to produce LDL. The most notable adverse events in the study were loose stools and elevation of liver transaminase levels and accumulation of hepatic fat in some but not all of the patients studied.

Rader concluded, "Although our study establishes proof of concept, a longer-term study in more patients will be required to determine the benefits and risks of this approach as a potential new therapy for homozygous familial hypercholesterolemia." Marina Cuchel, MD, PhD, a co-investigator in this study at Penn, is now the principal investigator of a Phase III study for this compound in homozygous FH patients that is funded by the U.S. Food and Drug Administration Orphan Drug program and planned for later this year.

Rader points out that this study is a superb example of "translational research" in which discoveries in basic science are "translated" into use in humans for the development of novel therapies. Rader is an internationally recognized leader in translational research in the areas of cholesterol metabolism and heart disease prevention. Penn recently created a new Cardiovascular Institute that is charged with promoting translational research in the diagnosis, treatment, and prevention of cardiovascular disease. Additionally, Penn was recently awarded a large NIH grant to foster the further development of translational research under the auspices of the newly created Institute for Translational Medicine and Therapeutics.

The results of this study are in The New England Journal of Medicine (http://content.nejm.org). The article is titled "Inhibition of Microsomal Triglyceride Transfer Protein in Homozygous Familial Hypercholesterolemia."

Power of Hallucinogenic Mushrooms Revealed: "Power of Hallucinogenic Mushrooms Revealed

Call it a 'shroom with a view: Researchers at Johns Hopkins University found that people who took psilocybin, the active ingredient in hallucinogenic mushrooms, ranked the experience as one of the most meaningful experiences in their life. This is the first detailed examination of the psychological impact of psilocybin since the late 1960s, when hallucinogens came under regulatory scrutiny.

Roland Griffiths and his colleagues worked with 36 subjects who had never taken hallucinogens before, but all reported at least intermittent participation in religious or spiritual activities such as church services, prayer, or meditation. In two or three 8-hour sessions, with two months in between each session, the volunteers were given either psilocybin or Ritalin. Seven hours later, and again months afterward, they completed questionnaires about their experience. More than 60 percent of the subjects who received psilocybin had what they described as a 'complete mystical experience.' Only 11 percent of the placebo group did. Two months later, 71 percent recalled it as one of the five most spiritually significant events in their lives..."

Study says new blood tests are no better than the old methods for predicting heart attacks CLICK FOR MORE: "New blood tests that doctors hoped would more accurately predict which patients are headed for a heart attack or stroke are no better than cholesterol levels, blood pressure and other conventional measurements, a study found.

Doctors in recent years had become excited over substances in the blood that appeared to be powerful new predictors of a heart attack. These substances included C-reactive protein, or CRP; homocysteine; and BNP, or B-type natriuretic peptide.

An increasing number of family doctors have been ordering expensive tests for these substances, and some patients have started requesting them, in hopes of identifying people who do not have the standard risk factors but are still likely to suffer a heart attack or stroke.

But the new research, by scientists at the highly regarded Framingham Heart Study, found that tests of CRP, BNP, homocysteine and seven other substances are only a couple of percentage points better at predicting outcomes than the standard, commonsense risk factors that doctors have known for decades."

New heart disease markers no better than old: study� CLICK FOR MORE: "Sophisticated screening tests are no better at predicting life-threatening heart problems than simple old-fashioned risk factors such as diabetes, high blood pressure and cholesterol, a study showed on Wednesday.

Thomas Wang of the Massachusetts General Hospital and his colleagues looked at 10 'biomarkers' that try to evaluate risk for heart disease, including C-reactive protein and homocysteine.

Their conclusion to be published in Thursday's New England Journal of Medicine: don't bother.

'The traditional risk factors that have stood the test of time turn out to be the best evaluation of risk,' Wang told Reuters.

He said some of the tests have other functions in medicine and might help doctors better understand heart disease.

But when it comes to using them to routinely test patients to assess their risk, 'there doesn't seem to be a role for keeping these biomarkers,' he said.

The conclusion is based on the longtime Framingham Heart Study in Massachusetts in which 3,209 participants were followed for up to 10 years to see if any of the markers could foretell who would have a heart attack, stroke, or heart failure..."

HOW A LITTLE RED WINE PROTECTS AGAINST STROKE DAMAGE

Johns Hopkins Medicine PRESS RELEASE:

Researchers at Johns Hopkins say they've discovered how red wine protects the brain from damage following a stroke.

Feeding normal mice a single modest dose of a chemical found in red grape skins and seeds two hours before inducing stroke-like damage, the scientists found that the animals suffered less brain damage than similarly damaged mice without benefit of the chemical.

Called resveratrol, the protective compound apparently increases a specific enzyme in the brain -- dubbed HO for heme oxygenase -- that was already known to shield nerve cells from deadly assaults.

In a separate study, the Johns Hopkins scientists treated mouse nerve cells with resveratrol and then bathed the cells in either a known cellular toxin or the toxin plus a drug that blocks HO. Blocking HO eliminated most of resveratrol's protective effects on nerve cells, causing cells to die. Cells treated with resveratrol but not blocked for HO survived 60 percent longer than those not treated.

Although it's hard to determine equivalent doses of resveratrol and Bordeaux, "the beneficial effects associated with having a glass of red wine with dinner could be explained by turning on the HO antioxidant system," says Sylvain Doré, Ph.D., an associate professor in anesthesiology, critical care medicine and neuroscience at Johns Hopkins. "There may be a scientific basis for the French Paradox after all," he says of the observation that frequent consumers of red wine seem more resistant to cardiovascular diseases

CAMPATH: NEWS MS DRUG WITH GREAT POTENTIAL
Phase III MS study planned

...The companies are also pressing on with plans to start a Phase III study of Campath for the treatment of relapsing/remitting multiple sclerosis, although this strategy has run into difficulties of late. They were forced to halt dosing in a Phase II trial of Campath for MS after a patient died of a serious bleeding disorder.

However, the drug's efficacy was seen to be excellent, cutting the relapse rate in patients by 75% compared to the comparator drug, Serono's blockbuster Rebif (interferon beta-1a).

Furthermore, Campath is given just once a year, while Rebif is administered three times a week, providing another significant treatment advantage.CLICK FOR FULL STORY

Moderate Drinking Lowers Death Risk - MedPage Today:
In a meta-analysis of 34 prospective studies, a few drinks a day -- one to two for women and two to four for men -- led to lengthier lives, found Augusto Di Castelnuovo, Sc.D., of the Catholic University here, and colleagues.

"Our data show that consumption of little amounts of alcohol leads to a reduction of mortality up to 18%," Dr. Di Castelnuovo said. But, he cautioned, "after a certain number of glasses things radically change" and the risk of death rises again.

The finding was based on an analysis of studies involving 1,015,835 persons and 94,533 deaths, Dr. Di Castelnuovo reported in the Dec. 11 issue of the Archives of Internal Medicine.

Previous studies have shown an inverse relationship between moderate alcohol consumption and coronary heart disease, Dr. Di Castelnuovo and colleagues said, but this is the first to show a similar effect for all-cause mortality."Moderate drinking has a protective effect on all-cause mortality, not only coronary heart disease...."

CHOCOLATE "OFFENDERS" TEACH SCIENCE A SWEET LESSON

CHOCOLATE "OFFENDERS" TEACH SCIENCE A SWEET LESSON
-- Study helps explain heart benefits from daily - but small - dose of chocolate

(Oral presentation #11865, Room S106b, Chicago Convention Center)

Some "chocoholics" who just couldn't give up their favorite treat to comply with a study to test blood stickiness have inadvertently done their fellow chocolate lovers - and science - a big favor.

Their "offense," say researchers at Johns Hopkins led to what is believed to be the first biochemical analysis to explain why just a few squares of chocolate a day can almost halve the risk of heart attack death in some men and women by decreasing the tendency of platelets to clot in narrow blood vessels.

"What these chocolate 'offenders' taught us is that the chemical in cocoa beans has a biochemical effect similar to aspirin in reducing platelet clumping, which can be fatal if a clot forms and blocks a blood vessel, causing a heart attack," says Diane Becker, M.P.H., Sc.D., a professor at the Johns Hopkins University's School of Medicine and Bloomberg School of Public Health.

Becker cautions that her work is not intended as a prescription to gobble up large amounts of chocolate candy, which often contains diet-busting amounts of sugar, butter and cream. But as little as 2 tablespoons a day of dark chocolate - the purest form of the candy, made from the dried extract of roasted cocoa beans - may be just what the doctor ordered.

Researchers have known for nearly two decades that dark chocolate, rich in chemicals called flavonoids, lowers blood pressure and has other beneficial effects on blood flow. The latest Johns Hopkins findings, to be presented Nov. 14 at the American Heart Association's annual Scientific Sessions in Chicago, identified the effect of normal, everyday doses of chocolate found in ordinary foods, unlike previous studies that found decreased platelet activity only at impractically high doses of flavonoids equivalent to eating several pounds of chocolate a day.

"Eating a little bit of chocolate or having a drink of hot cocoa as part of a regular diet is probably good for personal health, so long as people don't eat too much of it, and too much of the kind with lots of butter and sugar," says Becker.

In the study, 139 people Becker - whom Becker somewhat tongue in cheek calls "chocolate offenders" - were disqualified from a much larger study looking at the effects of aspirin on blood platelets. The Genetic Study of Aspirin Responsiveness (GeneSTAR) was conducted at johnd Hopkins from June 2004 to November 2005 and enrolled more than 500 men and 700 women participants nationwide.

Shortly before aspirin dosing began for the subjects, they were told to stay on a strict regimen of exercise and to refrain from smoking or using foods and drinks known to affect platelet activity. These included caffeinated drinks, wine, grapefruit juice - and chocolate.

The non-compliers - who admitted to eating chocolate - were a diverse group who got their flavonoid "fix" from a variety of sources, including chocolate bars, cups of hot cocoa, grapes, black or green tea, and strawberries. And while they were excluded from the aspirin study, Becker and her team scoured their blood results for chocolate's effect on blood platelets, which the body recycles on a daily basis.

When platelet samples from both groups were run through a mechanical blood vessel system designed to time how long it takes for the platelets to clump together in a hair-thin plastic tube, the chocolate lovers were found to be less reactive, on average taking 130 seconds to occlude the system. Platelets from those who stayed away from chocolate as instructed clotted faster, at 123 seconds.

In another key test of urine for waste products of platelet activity, primarily urinary thromboxane (11-dehydro-thromboxane B2), scientists found that chocolate eaters showed less activity and waste products on average, at 177 nanograms per millimol of creatinine, versus an average of 287 nanograms per millimol of creatinine in the group that abstained.

Participants ranged in age from 21 to 80; 31 percent were black and the rest were white. In total, more than 200 different tests of platelet reactivity were performed and analyzed in the study. Because whole blood contains other cells that affect platelet aggregation, testing was repeated using a purified version of test samples made up of strictly platelet-rich plasma.

None of the "offenders" had previous histories of heart problems, such as a heart attack, but all were considered to be at slightly increased risk of heart disease because of family history. Fifty percent of women participants were postmenopausal.

"These results really bring home the point that a modest dietary practice can have a huge impact on blood and potentially on the health of people at a mildly elevated risk of heart disease," says study co-author Nauder Faraday, M.D., an associate professor at Johns Hopkins. "But we have to careful to emphasize that one single healthy dietary practice cannot be taken alone, but must be balanced with exercise and other healthy lifestyle practices that impact the heart."

PRESS RELEASE: STEM CELLS SHOW PROMISE IN REPAIRING ANIMALS' HEART ATTACK DAMAGE

FOR IMMEDIATE RELEASE

ADULT PIG STEM CELLS SHOW PROMISE IN REPAIRING ANIMALS' HEART ATTACK DAMAGE
(Oral presentation #732, Room E354b, Chicago Convention Center)

Johns Hopkins scientists have successfully grown large numbers of stem cells taken from adult pigs' healthy heart tissue and used the cells to repair some of the tissue damage done to those organs by lab-induced heart attacks. Pigs' hearts closely resemble those in humans, making them a useful model in such research.

Following up on previous studies, Johns Hopkins cardiologists used a thin tube to extract samples of heart tissue no bigger than a grain of rice within hours of the animals' heart attacks, then grew large numbers of cardiac stem cells in the lab from tissue obtained through biopsy, and within a month implanted the cells into the pigs' hearts. With help from a blue-dye tracking system, the scientists have shown that within two months the cells had developed into mature heart cells and vessel-forming endothelial cells.

"This is a relatively simple method of stem cell extraction that can be used in any community-based clinic, and if further studies show the same kind of organ repair that we see in pigs, it could be performed on an outpatient basis," says Eduardo Marbán, M.D., Ph.D., senior study author and professor and chief of cardiology at the Johns Hopkins University School of Medicine and its Heart Institute. "Starting with just a small amount of tissue, we demonstrated that it was possible, very soon after a heart attack, to use the healthy parts of the heart to regenerate some of the damaged parts."

Marbán cautions that no overall improvements in heart function have yet been shown in these studies, which were not designed to establish such changes and used relatively low numbers of infused cells (10 million or less). "But we have proof of principle, and we are planning to use larger numbers of cells implanted in different sites of the heart to test whether we can restore function as well," he says. "If the answer is yes, we could see the first phase of studies in people in late 2007."

The latest Johns Hopkins findings are scheduled to be presented Nov. 13 at the American Heart Association's annual Scientific Sessions in Chicago. They are believed to be the first results in animal studies to show that so-called cardiac stem cell therapy can be successfully applied with minimally invasive methods to circumstances closely resembling those in humans. Scientists say the results build on earlier studies with cardiac stem cells in mice and humans that demonstrated success in regenerating infarcted heart muscle and restoring heart cell function post-infarct.

For the study, cardiac stem cells were extracted by tissue biopsy from eight pigs whose main arterial blood supply was tightened for more than two hours, duplicating the effects and damage caused by heart attack.

Using techniques developed in Marbán's lab, researchers extracted about a million cardiac stem cells from undamaged heart tissue, growing them without the use of potentially dangerous chemical stimulators.

After three weeks, the stem cells turned into spherical balls of cells that mimicked the electrical properties of heart muscle cells. The so-called cardiospheres yielded on average more than 14 million cells.

Within a month after the initial heart attack, a catheter tube was inserted into an artery in the pig leg for infusing the cardiospheres. Previous research had shown that they would on their own migrate to the damaged zones of the heart. Marbán's team was able to confirm this because they had labeled the stem cells with a gene that codes for an enzyme producing a blue dye, which could be seen under a microscope.

Months later, when researchers examined the hearts to see if any damaged tissue had been repaired, they found blue spots indicating where the stem cells had taken root.
Closer examination of results revealed that stem cells had matured and grown in the border zones of the damaged area, where researchers suspect both dead and living tissue mingle and some blood supply remains.

"The goal is to repair heart muscle weakened not only by heart attack but by heart failure, perhaps averting the need for heart transplants," says Peter Johnston, M.D., study author and a Reynolds Foundation postdoctoral cardiology research fellow at Johns Hopkins' Heart Institute. "By using a patient's own adult stem cells rather than a donor's, there would be no risk of triggering an immune response that could cause rejection."

Lower Income Means Higher Risk for Heart Disease: USC PRESS RELEASE
Protein linked to heart disease found to be more prevalent in low-income people, minorities and women. Findings may help explain why the poor age faster, say USC and UCLA researchers.

Low-income adults are more likely to have very high levels of C-reactive protein (CRP), a risk factor for heart disease, according to a study led by researchers at the University of Southern California.

The study, published in the current issue of Brain, Behavior and Immunity, finds that among adults with income levels at or below the poverty line, 15.7 percent had very high levels of CRP, compared to only 9.1 percent of those in families above the poverty line.

"We have long known that poor people have worse health," said Eileen Crimmins, corresponding author and professor in the USC Leonard Davis School of Gerontology. "This paper provides evidence that people living at or near the poverty line are almost twice as likely to have very high CRP, which poses risks for long-term, chronic conditions like heart disease and cognitive loss. This may be one of the explanations for why poor people age faster."

CRP is produced as part of the immune response to inflammation. In healthy individuals, CRP levels return to normal after infection or injury subsides. However, some people have chronically elevated levels of CRP. Recent studies have shown high levels of CRP to be a useful predictor of heart disease.

Recent illness, chronic conditions and lifestyle account for some but not all of the explanations for the association between high CRP levels and socioeconomic standing.

"We found that even after accounting for various risk factors, people in poverty still had higher CRP," said Dawn Alley, another corresponding author and a recent doctoral graduate from the USC Davis School. "This suggests that even beyond issues like health behaviors and chronic conditions, there is something about poverty that makes people sick, and at least part of this effect is working through CRP."

The study also found that African Americans, Hispanics and women are more likely to have high levels of CRP, and that obesity is the largest contributor to above normal CRP levels.

The findings, which were funded by the National Institutes of Health, provide a better understanding about risk factors for poor health outcomes later in life.

The Division of Geriatrics at the UCLA School of Medicine also contributed to the study.

News Review From Harvard Medical School -- Value of Sealing Hole in Heart Debated
Makers of a device that seals a small hole in the heart are being told to prove that it is helpful. Until the studies are done, the U.S. Food and Drug Administration has tightened rules on marketing the devices, the Associated Press reported October 30. About 1 in 5 adults has a small hole in the heart called a patent foramen ovale. Such a hole is present in about 60% of younger adults who have strokes. However, it's not clear if the hole causes strokes or if sealing it prevents strokes. This is what the new studies would show.

By Howard LeWine, M.D.
Harvard Medical School

What Is the Doctor's Reaction?

A small hole between the two upper chambers of the heart has caused a big controversy.

Before we are born, all of our oxygen supply comes from our mothers' blood. So it doesn't matter if blood mixes between the two sides of the heart. It's normal for a fetus and newborn baby to have an opening that allows blood to move between the two upper chambers (the atria).

After we are born and need to breathe air to get oxygen, this connection is supposed to close. The heart has its own natural way to fix it. There is a flap on the upper left chamber wall. The pressure is higher in the upper left chamber than in the right chamber. So the higher pressure pushes the flap over the hole. In time, this flap usually gets permanently attached.

However, in 1 out of every 5 of us, the hole doesn't close permanently and completely. The opening is the foramen ovale, and when it stays open it is called a patent foramen ovale (PFO). Many millions of people who have this never know they have it, nor do they need to know.

The potential importance of a PFO was recognized in the 1960s. During this decade, doctors were regularly using ultrasound to take pictures of the heart (echocardiography) for many reasons, one of them to diagnose the cause of a stroke.

Doctors started seeing a higher-than-expected rate of PFO in people with strokes and TIAs (transient ischemic attacks, which can lead to a stroke). This seemed especially true for younger people not at traditional risk of stroke.

This association has led to an acceptance of PFO as a cause of TIA and stroke. The next natural step was to fix the hole either with surgery or by threading a device through the artery to close the hole. But now doctors are not so sure that this always needs to be done.

The waters have grown even muddier. More recently doctors have noticed that people with certain types of migraine (sometimes called complex migraine) also tend to have PFOs. The symptoms of a complex migraine can be just like those of a TIA or stroke.

What Changes Can I Make Now?

If you have complex migraine or symptoms that suggest of a TIA, your doctor may have ordered an echocardiogram as part of the evaluation. So what should you do if you are told you have a PFO?

There is no correct answer. Although it is not likely that the PFO is actually causing your symptoms, the two can have a direct relationship.

Here is one example of a direct relationship. If you have an untreated blood clot in a vein, a piece of that blood clot can break off and travel to the right side of your heart. If there is an opening between the upper right and left chambers, the clot can move across the PFO. It then travels into the lower left heart chamber, where it exits into the aorta. From here, the clot can travel to the brain and cause a TIA or stroke.

In this situation, the person takes blood thinners initially and then has a procedure to close the PFO.

In another example, a person with a PFO who has TIA-like symptoms and blood that clots too easily would be considered for PFO closure.

But most of the time, the situation is not so straightforward. You and your doctor will balance the risks and benefits of the options, usually taking an aspirin or other blood thinner or having the PFO closed.

Pretoria News: Three-hour rule would halve stroke burden
A stroke patient who is treated at a stroke unit within three hours of becoming ill has a 50% chance of full recovery, according to a German neurologist.

According to Professor Werner Hacke, chairman of the University of Heidelberg's department of neurology in Germany, the damage caused by stroke could be halved if patients (and their doctors) identified the problem quickly and sought help.

"Symptoms of stroke are well known. Can the patient lift both arms to an equal level? Can they say their name properly? Can they stand up and walk?" said Hacke.

Stroke is the biggest cause of disability in South Africa.

For this reason governments everywhere should do everything possible to improve stroke care to reduce the burden of stroke disability on the state, said Hacke.
javascript:void(0);
He said one solution for developing countries was to use the Internet more in the treatment of the illness.

This could involve sending live images of the patient to a neurologist based in a city hospital.

"The technology is so good now that a doctor can be in another city and still look into a patient's eyes," he said.

This technology was not expensive (R100 000 for a unit) but needed political co-operation to be installed and properly used.

Flu shots: Important for people with heart disease - Mayo Clinic
Flu shots are recommended for anyone with heart disease.

Find out why from a Mayo Clinic specialist who helped develop the flu shot recommendations: Larry Baddour, M.D.

If you have heart disease, you should get an annual flu shot. That's the message put out by the American Heart Association and the American College of Cardiology. Studies have shown that death from the flu (influenza) is more common among people with cardiovascular disease than among people with any other chronic condition. Doctors have long recommended that older adults and other high-risk groups get flu shots, but are now placing more emphasis on the importance of flu shots for those with heart disease. The flu shot could prevent thousands of flu-related complications and deaths every year in people who have heart disease.

Larry Baddour, M.D., an infectious diseases specialist at Mayo Clinic and professor of medicine at Mayo Clinic College of Medicine, was on a joint American Heart Association and American College of Cardiology advisory panel that developed the recent recommendation. He shares his insight about the group's recommendation.

Why are flu shots important for those with heart disease?

According to the Centers for Disease Control and Prevention (CDC), the flu is estimated to cause more than 36,000 deaths annually in the United States. In addition, it sends 225,000 people to the hospital. The rate of flu-related complications is even higher for people with heart disease.

If you have heart disease, you are at increased risk of complications from the flu — including pneumonia, respiratory failure, heart attack and death. Having the flu can also cause dehydration and worsen heart failure, diabetes or asthma.

Most scientific evidence indicates that flu shots are associated with a reduced risk of cardiovascular events — such as heart attack — in people with known cardiovascular disease.

Is it safe to get a flu shot if I have heart disease?

Flu shots are safe for most people who have heart disease. Get your flu vaccine injected by needle, usually in the arm. Some people develop mild arm soreness at the injection site. The flu vaccine that is given by nasal spray isn't recommended for people with heart disease because it's made with live virus that can trigger flu symptoms in people with heart disease.
When should I get a flu shot?

If you have heart disease, get the flu shot each fall when it becomes available, usually late September through November. However, if flu shots are still available and you haven't yet received a vaccination, you'd still benefit from getting a flu shot in January or later. That's because the flu season doesn't typically peak until January, February or March.

Harvard Medical School: 10 steps to lower your blood pressure

High blood pressure isn’t usually something that can be cured. Like an in-law who comes to stay for good, it’s something most people need to learn to live with. Drugs offer an easy fix, but most also cause unwanted side effects. Making healthful lifestyle changes is harder, but it yields benefits far beyond better blood pressure. That’s why it makes sense to start with these, and add medications only if needed. Here are 10 steps that can help you lower your blood pressure and keep it under control.

1. Check it. You can’t do much about your blood pressure unless you know what it is. Your doctor should check it at every visit. Measuring it at home is even better. Relatively inexpensive home monitors are available in most pharmacies.

2. Get moving. Regular exercise, even something as simple as brisk walking, improves blood vessel flexibility and heart function. It can lower blood pressure by 10 points, prevent the onset of high blood pressure, or let you reduce your dosage of blood pressure medications.

3. Eat right. A landmark study called Dietary Approaches to Stop Hypertension (DASH) showed that you can eat your way to better blood pressure. The DASH diet emphasizes fruits, vegetables, low-fat dairy products, whole grains, poultry, fish, and nuts, and downplays red meat, sweets, sugar-containing beverages, and saturated fat and cholesterol.

4. Control your weight. If you are carrying too many pounds for your frame, losing weight can lower your blood pressure. You don’t need to become rail-thin — losing 10% of your current weight, or even 10 pounds, can make a big difference.

5. Don’t smoke. Nicotine constricts small blood vessels. Smoking a cigarette can cause a 20-point spike in systolic blood pressure. Quitting is tough, but there are now more aids to help.

6. Drink alcohol in moderation. A drink a day for women and one or two a day for men is good for the heart and blood vessels. Going beyond that can contribute to higher blood pressure.

7. Shake up your salts. Too much sodium and too little potassium boost blood pressure in people who are sensitive to salt. The imbalance is so great that the American Medical Association is calling for food makers and restaurants to cut the sodium content of food by 50% by 2016. Aim for less than 1.5 grams of sodium a day, and at least 4.7 grams of potassium.

8. Sleep is good. Burning the candle at both ends night after night can contribute to high blood pressure, not to mention increase the chances of developing heart disease or a sudden cardiac arrest. How much sleep is enough? At least six hours a night, though eight hours is probably more like it for most people.

9. Reduce stress. As surely as mental and emotional stress can raise blood pressure, meditation, deep breathing, and other stress-busting activities can lower it.

10. Stick with your medications. Taking pills to keep your blood pressure in check won’t make you feel any different. But it can keep you from having a stroke, heart attack, or other problem.

Dozens of drugs are available for lowering blood pressure. They come in a range of regimens (once a day to several times a day) and costs, and have a range of effects on other conditions, interactions with other drugs, and potential side effects.

Which drug is best for treating high blood pressure is one of the major controversies in medicine today. Current guidelines as of 2006 say that the first choice should be an inexpensive diuretic (water pill). Some experts argue that an ACE inhibitor or a calcium-channel blocker is a better place to start. In reality, what’s best for you isn’t necessarily right for someone else. Most people need more than one medication to get their blood pressure under control, and one of these should probably be a diuretic.

High blood pressure, like almost everything else in medicine, is a highly personal condition. Preventing it, and keeping it from doing you harm, requires careful, individualized evaluation from your doctor and focused commitment on your part.

Body Mass Index faulted as tool to gauge heart risk
....And now some researchers from the Mayo Clinic are saying the BMI is just too blunt to be trusted. A study found that patients with a low BMI had a higher risk of death from heart disease than those with normal BMI, according to the research published in the Aug. 19 issue of The Lancet. At the same time, overweight patients had better survival rates and fewer heart problems than those with a normal BMI.

Where does BMI fall apart? First, it was never meant to do anything more than screen a large population, and it's used primarily because it's easy and cheap. But doctors often employ it to measure bone-mineral density and heart-attack risk.

There's a growing sentiment that this is a mistake. A recent study in the Journal of Clinical Densitometry found that weight alone is a much better predictor of bone-mineral density than BMI.

And when it comes to heart-
attack risk, your waist-to-hip ratio, which measures fat distribution, also tells doctors more than BMI, according to Italian researcher Maria Grazia Franzosi. (People with more weight around their waist are at greater risk of heart disease and diabetes than those with weight around their hips.)
Also, BMI can't differentiate between body fat and muscle mass, so highly trained athletes can have a high BMI and not be overweight. The most extreme example is that, in his prime, as Mr. Universe, Arnold Schwarz-
enegger's BMI was 33. That qualifies as obese.....MORE... Body Mass Index faulted as tool to gauge heart risk

Two scientific reviews of the health effects of dietary fish
Two scientific reviews of the health effects of dietary fish intake probably made bigger splashes than expected by being released on the same day.

Earlier this week, the Institute of Medicine (IOM) released Seafood Choices: Balancing Benefits and Risks, its summary of current knowledge on the health benefits of eating fish and the potential risks from contaminants such as methylmercury, dioxins, and polychlorinated biphenyls (PCBs) [1]. The same day, a literature review on much the same topic was published by the Journal of the American Medical Association [2].

Both documents offer positive messages about the health effects of the n-3 polyunsaturated fatty acids (PUFAs) eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) abundant in fish and other seafood. The IOM report arrives at no firm conclusions about whether the regular consumption of fish will prevent disease. The JAMA report's authors, however, appear certain that its health benefits outweigh any risks.

As covered by heartwire earlier this week, Dr Dariush Mozaffarian (Harvard School of Public Health, Boston, MA) and Dr Eric B Rimm (Brigham and Women's Hospital, Boston, MA) found that intake of EPA and DHA equivalent to one or two servings of fish per week was associated with a 36% decrease in the risk of death from coronary heart disease (p<0.001) and a 17% drop in total mortality (p=0.046). They also concluded that the n-3 PUFAs are likely important to early brain development. Those benefits far outweigh any risks from contaminants, they write.

"Avoidance of modest fish consumption due to confusion regarding risks and benefits could result in thousands of excess CHD deaths annually and suboptimal neurodevelopment in children," they write.

The IOM report's dietary recommendations are more circumspect and less concrete. The document "confirms that eating fish and shellfish may reduce people's overall risk for developing heart disease," according to a press release from the organization [3]. "It is not certain whether this is because substituting the lean protein of seafood for fatty cuts of meat reduces consumers' intake of saturated fat and cholesterol or because of the protective effects of omega-3 fatty acids. . . . The report also found evidence that maternal consumption of omega-3 fatty acids through seafood can contribute to vision and cognitive development in infants and lengthen the duration of gestation."

The report acknowledges potential risks from methylmercury, dioxins, and PCBs but notes, according to the IOM statement, that "reliable data on the distribution of some contaminants is lacking, and there is little evidence on how beneficial effects of seafood might counteract some of the risks from contaminants."

Both reports include caveats about contaminant exposure and fish intake for special populations, particularly women of childbearing age or who are nursing, and cautions for people who fish and eat their own catch from potentially polluted inland waters.

More than 400 pages long and designed to help the US government communicate these issues to the public, the IOM report is noteworthy for observing how little is actually known about either the benefits or the risks of consuming fish and for identifying knowledge gaps that can help guide future research. The IOM, an arm of the National Academy of Sciences (NAS), a nonprofit corporation, describes itself as "an adviser to the federal government on issues of medical care, research, and education."

Decaf Coffee Questions Percolate, Study: Decaf Drinkers May Have Increased Heart Risks - CBS News (click for more):
"Caffeinated coffee may have an undeserved bad rap, suggests a new study that shows the decaffeinated variety may have harmful heart effects.

The study, presented at the annual meeting of the American Heart Association, showed that people who drank decaf had higher levels of a protein linked to heart disease risk compared with those who drank caffeinated coffee or no coffee.

But the differences were fairly small and there's probably no health threat from drinking a cup or two of any type of coffee a day, says researcher H. Robert Superko, MD, chairman of preventive cardiology at the Fuqua Heart Center in Atlanta.

FDA approves heart health claim for canola oil (click for more):
"The FDA has approved a qualified health claim on canola oil labels that states it supports heart health and reduces the risk of coronary heart disease due to its unsaturated fat content.

The heart healthy claim -also found on oils such as phytosterols, omega-3s and olive oil -is popular among nutraceutical companies because consumers are spending more on healthier foods. The U.S. Canola Oil Association petitioned to be able to make the claim in January in order to promote the benefits of canola oil.

'The claim may ... encourage food manufacturers and food service providers to substitute canola oil for other oils with less favorable nutritional profiles,' said USCA president John Haas, who added that he expects the availability of the claim to promote consumer health by informing them of a simple, affordable and convenient strategy to reduce heart disease risk.

Studies suggest canola oil is high in healthy unsaturated fats, free of cholesterol and trans fats, and has the lowest saturated fat content of any common edible oil. Because canola oil is low in LDL (bad) cholesterol, the labels will be allowed to say:

'Limited and not conclusive scientific evidence suggests that eating about 1 1/2 tablespoons (19 grams) of canola oil daily may reduce the risk of coronary heart disease due to the unsaturated fat content in canola oil. To achieve this possible benefit, canola oil is to replace a similar amount of saturated fat and not increase the total number of calories you eat in a day. One serving of this product contains (x) grams of canola oil.'

'There is ample scientific evidence to demonstrate these benefits from the unsaturated fats in canola oil,' Haas said. 'By using it in place of other common edible oils, consumers can increase their compliance with the latest dietary recommendations.'

However, insiders are worried about what the move may mean for the industry as a whole. Since the health claims promote all canola oils, some companies have wondered why they would invest in claims that increase the sales of their competitors. Also, canola oil, along with olive oil, was granted it's heart health claim by the FDA because of it's low level of unsaturated fats, and experts say this may spur industry representatives for other oils to petition for the claim because of their oils' similar properties..."

Study Says Aspirin Has A Gender Gap, Drug May Help Women Prevent Strokes, Men Heart Attacks - CBS News:
"It is a medical mystery that doctors find more and more intriguing: how drugs can have different effects on men and women. And the latest evidence indicates that aspirin may be a startling example.

CBS News correspondent Elizabeth Kaledin reports that a new study shows aspirin does a better job of protecting women from strokes than from heart disease. And it works altogether differently for men.

The latest research tracked 95,000 healthy patients with no prior heart problems. For women, an aspirin a day reduced the risk of stroke by 17 percent, with no effect on heart attack.

But for men, the benefits were reversed. A daily dose of aspirin cut the risk of heart attack by 32 percent, but had no effect on strokes.

Dr. Nieca Goldberg specializes in cardiac care for women at Lenox Hill Hospital and hopes this data will trigger similar studies in the future.

'I think that this is clearly the time that we need to look at other medications for gender related differences,' said Goldberg.

Aspirin is not alone in this area. Several other drugs have shown signs of reacting differently in women, including some anti-depressants, painkillers and even anesthesia.

No one knows for sure why these differences exist because there have not been enough studies to pinpoint the causes. But doctors have theorized that women's smaller size and higher body fat could be factors. Also, women tend to take more drugs than men, such as birth control.

For patients, the news is more food for thought. Ruth Oakes has been taking an aspirin a day to prevent heart disease for the past six years and is contemplating this latest twist.

'I think it's interesting that we discover more and more men and women are different in our responses to medication,' said Oakes. 'It does not surprise me about aspirin.'

Goldberg agrees and says much remains to be explored in the area of gender specific medicine.

'We don't even know if maybe women should be on lower dosages of medicines compared to men,' she said."

Antioxidant, polyphenol-rich Med diet could slash Alzheimer’s risk (click for more):
"The Med diet, rich in cereals, wine, fruits, nuts, legumes and whole grains, fish and olive oil, has been linked to longer life, less heart disease, and protection against some cancers. The diet's main nutritional components include beta-carotene, vitamin C, tocopherols, polyphenols, and essential minerals.

It is these antioxidants and polyphenols that appear to offer protection, suggest the researchers from Columbia University, and not to any impact on general cardiovascular health.

Although the mechanism of Alzheimer's is not clear, more support is gathering for the build-up of plaque from beta-amyloid deposits. The deposits are associated with an increase in brain cell damage and death from oxidative stress.

It is against the oxidative stress that the Mediterranean diet could offer protection.

The findings of Nikolaos Scarmeas and his colleagues, published on-line ahead of print in the Archives of Neurology (doi: 10.1001/archneur.63.12.noc60109), are based on results from a study of 194 Alzheimer disease (AD) cases (average age 82) and 1790 non-demented controls (average age 76). The controls had almost equal representation of White, Black and Hispanic subjects, while 59 per cent of the AD cases were Hispanic, 31 per cent Black and 9 per cent White.

Dietary assessment was performed by asking the subjects to complete a validated 61-item semi-quantitative food frequency questionnaire, while AD diagnosis took place in a university hospital setting.

After adjusting the results for possible confounding factors, such as age, education, BMI, smoking status, and ethnicity, the researchers reported that people with the highest adherence to a model Mediterranean diet were associated with a 60 per cent lower risk of Alzheimer's disease, compared to people with the lowest adherence to the diet..."

Coffee May Cut Diabetes Risk, Study: Lots Of It, Especially Decaf, Seems To Have That Effect - CBS News (click for more):
"A new study finds that drinking a lot of coffee, especially decaf, may help prevent diabetes.

On The Early Show Tuesday, medical correspondent Dr. Emily Senay elaborated on the possible good news for those who enjoy their cups of joe.

She reported that a new study in the Archives of Internal Medicine shows that coffee can reduce the risk of type 2 diabetes, the type that normally develops over time as a result of obesity as the body loses its ability to use insulin to regulate blood sugar.

The study looked at more than 28,000 post-menopausal women over an eleven-year period. They answered questions about their coffee consumption.

The study found that coffee seems to offer protection against type 2 diabetes, with decaf coffee providing the most protection. Compared to women who drank no coffee, Senay explained, women who drank more than six cups of any type of coffee per day were 22 percent less likely to be diagnosed with diabetes. Women who drank more than six cups of decaffeinated coffee daily had a 33 percent reduced risk.

Six cups a day is a lot of coffee, Senay observed. The American Heart Association recommends no more than one to two cups of caffeinated coffee per day. There are no specific recommendations for decaf coffee.

More research is needed to see whether coffee might play a role in diabetes prevention, Senay says. Regular exercise, good diet and a regular checkup with the doctor are the best ways to prevent diabetes, she adds..."

Sorting Out Statins, Wonder Drug? (Click for more): "They've been called wonder drugs, healing ailments from heart disease to Alzheimer's disease.

But who should be on a statin?

About 11 million Americans take cholesterol-lowering drugs known as statins, one of the nation's most widely-sold drugs. Some doctors say they're over-prescribed while others say they're not prescribed enough.

Elaine Overton's cholesterol was 260, so her doctor put her on Lipitor to lower her cholesterol.

'My cholesterol dropped about 100 points in about six weeks' time really remarkable,'Overton said.

Statins can lower cholesterol by 40 percent and prevent heart attacks. The newest research shows they also reduce the risk of a second stroke by 16 percent.

'If anything, they're under-prescribed,' said Dr. K. Michael Welch, neurologist in the Rosalind Franklin University of Medicine and Science in Chicago. 'They certainly have been under-prescribed for stroke.'

Chewin' the fat...All about good, bad cholesterol (Click for more):
"The word cholesterol may sound harmless. After all, one dictionary defines it simply as a white substance found in animal tissue. In truth, cholesterol can be very dangerous and accounts for a growing number of heart disease cases in the United States, and it may be implicated in many of the 500,000 heart disease deaths here each year.That makes cholesterol a silent killer, said Dr. Elena Citkowitz, who runs the Cholesterol Management Center at the Hospital of St. Raphael in New Haven and is director of its Cardiac Rehabilitation Program.

Cholesterol is a fat that the body makes and it's important to the human make-up.

Of course, the public has become pretty savvy about the substance itself. We know there is a difference between the good cholesterol, or HDL, and the bad, or LDL.

Sadly, few people are doing enough to raise the good and lower the bad. They generally wait until their bad cholesterol levels are sky high and only then consider altering their diet as one possible corrective measure..."

To determine the validity of this approach, the study authors reviewed research on LDL cholesterol and heart health. They said they found no scientific evidence to support the ultra-low LDL target.

The researchers concluded that it would be better to concentrate less on cholesterol and to get more people with multiple heart disease risk factors to take statin drugs -- regardless of the patients' cholesterol levels..."

Plant Sterols Added to Orange Juice May Do the Heart Good - Plant sterols added to orange juice can significantly reduce markers of cardiovascular risk, researchers here reported.
Action Points

* Explain to interested patients that plant sterols can be found in small quantities in foods, such as fruits, vegetables, nuts, seeds, cereals and legumes, and have been added to some margarines and other spreads.

* The National Cholesterol Education Panel and the FDA both recommend dietary plant sterols or stanols as helpful in reducing LDL-cholesterols and possibly the risk of cardiovascular disease as well.

One gram of plant sterols added into reduced-calorie orange juice reduced C-reactive protein by 12% (P<0.005) and significantly improved cholesterol levels compared with plain low-calorie OJ, reported Sridevi Devaraj, Ph.D., of the University of California at Davis here, and colleagues, in the October issue of the American Journal of Clinical Nutrition.

Downing the supplemented juice twice daily significantly decreased total cholesterol by 5% (P<0.01) and reduced LDL cholesterol by 9.4% (P<0.001) compared with study participants' baseline levels and compared to placebo.

Likewise, HDL levels improved significantly compared with baseline (6% increase, P<0.02), though not with placebo, over the eight-week period....

Two human blood cells that help fight blood loss, infection, and inflammation are responsible as well for starting a series of molecular events that results in overproduction of Cox-2, an enzyme involved in heart attack, stroke, atherosclerosis, and other inflammatory diseases.

The finding by researchers at the University of Utah and University of South Carolina means scientists may be able to develop drugs to prevent or lessen the severity of inflammatory diseases, such as atherosclerosis and heart attack. Discovery of the signaling mechanism will be invaluable in sorting out the roles Cox-2 plays in those diseases, according to Guy A. Zimmerman, M.D., University of Utah School of Medicine professor of internal medicine, senior author of the study detailing the research.

"This discovery has immediate clinical relevance," said Zimmerman, director of the medical school's Program in Human Molecular Biology and Genetics. "This opens the potential of developing medications for both the prevention of long-term atherosclerosis (clogged arteries) and the acute events of heart attack."

A possible link between psoriasis and heart-attack risk
ome of the same inflammation brought on by the immune system in the more severe form of psoriasis appears to put younger patients with the autoimmune disease at increased risk of a heart attack, according to a new study.

Researchers at the University of Pennsylvania School of Medicine found that younger patients with severe psoriasis had the highest relative risk of heart attack compared to people with only a mild form of the disease or patients without psoriasis.

Psoriasis is a common, lifelong inflammatory skin condition that affects about 4.5 million American adults, with about 150,000 new cases diagnosed each year. Although the condition typically appears in people in their 20s and 30s, it can develop at a younger age. When it does, the disease is likely to be more severe, with skin irritation and itching that affects more than 2 percent of the body.

About 20 percent of psoriasis patients have more severe and extensive involvement, and up to 30 percent also develop a related form of arthritis that causes joints to become inflamed.

Doctors have suspected that the inflammation may also extend to arteries, and several hospital-based studies have indicated that psoriasis is associated with a higher risk of cardiovascular disease and heart attack. But none of those studies took into account other risk factors for heart disease among the patients.

In the new study, published Wednesday in the Journal of the American Medical Association, Dr. Joel Gelfand, an assistant professor of dermatology at Penn and colleagues sought to evaluate the disease as a heart-risk factor in a large, general population....

Extended Release Niacin Reduces Cardiovascular Inflammatory Marker Lp-PLA2....Tufts-New England Medical Center
Niacin, in conjunction with statin therapy, reduces lipoprotein-associated phospholipase A2 (Lp-PLA2), an important new marker of inflammation associated with heart disease and stroke due to plaque rupture, according to a study published in the September 15, 2006, issue of The American Journal of Cardiology. The study, conducted at Tufts-New England Medical Center, evaluated 54 patients who were assigned either 1,000 mg daily extended release niacin or placebo, in addition to their existing drug regimen, primarily statins, ACE inhibitors, and aspirin.

The study shows that when extended release niacin was administered to stable heart disease patients for three months, Lp-PLA2 levels were reduced by 20 percent (p<0.05), while low-density lipoprotein (LDL) remained unchanged. Lp-PLA2 levels were measured by the PLAC test from diaDexus. The PLAC test is a simple blood test that measures the concentration of the enzyme Lp-PLA2, identifying people at high risk for heart disease and stroke associated with atherosclerosis, who may not be identified by traditional risk factors.

Prostate cancer treatment ups heart and diabetes risks:

"Hormone-suppressing therapy is not suitable for all cases of the disease, researcher says
A treatment for prostate cancer that blocks male hormone production is associated with increased risks for diabetes and heart disease -- and it's being used far more often than it should be, according to Boston researchers.

The Harvard Medical School group studied more than 73,000 men age 66 years and older who had been diagnosed with prostate cancer and followed for as long as 10 years.

More than 26,000 of the men had been treated with a drug called a gonadotropin-releasing hormone (GnRH) agonist. This form of 'chemical castration' blocks the production of male hormones that promote the growth of prostate tumours. But it has been associated with increased body fat and insulin resistance, a condition that increases the risk for developing diabetes.

Compared with men who were not given a GnRH agonist, the patients who did receive this treatment had a 44 per cent increased risk of developing diabetes, a 16 per cent increased risk of heart disease and heart-related sudden death and an 11 per cent increased risk of suffering a heart attack..."

3 steps to a healthier heart:

"Get out the tape measure.

People who carry weight in their midsections are at a higher risk for heart disease; now experts know just how much belly fat is bad. A recent study from McMaster University in Hamilton, Ontario, found that a waist-to-hip ratio greater than 0.85 increases your risk of cardiovascular disease (the bigger the tummy, the higher the risk). To figure out your ratio, divide your waist size by your hip size.

Fight fair.

Women who made hostile comments while quarreling with their husbands were more likely to have arteriosclerosis (hardening of the arteries) than wives who argued without being demeaning or spiteful, according to a new study from University of Utah on 150 long-married couples.

Be a good role model.

Your bad habits may put your children at risk later in life. If your mother has heart disease, you have a 43% greater chance of developing it; if your father has the disease, your risk is 17% higher, according to a new study. Surprisingly, lifestyle may have a bigger impact than genetics. So exercise, eat a healthy diet and don't smoke."

But in implementing that recommendation, take into account another of the authors' recommendations - rise and dine, i.e., eat a hearty breakfast.

If you need more to be persuaded, the authors offer this: 'A good breakfast can reduce the risk of heart disease, diabetes and cancer, while keeping your weight under control. It improves your mood and increases alertness. Yet roughly one-quarter of Americans start their day with out the powerful advantage of a good breakfast, according to a federal survey, and numerous studies indicate their performance at work or school suffers as a result.

Risk factors seen in young heart disease patients:

"Heart disease patients younger than 55 years of age can benefit substantially from cardiac rehabilitation and exercise training (CRET) programs, according to a report in Archives of Internal Medicine.

'Young coronary patients have a very abnormal risk profile, characterized by more obesity, (high cholesterol), and much higher psychological distress,' Dr. Carl J. Lavie from the Ochsner Medical Center in New Orleans told Reuters Health. 'All of these parameters, as well as many other aspects of the risk profile, markedly improve following formal CRET, including 50 to 80 percent reductions in the (rate) of these abnormal behavioral patterns.'

Lavie and Dr. Richard V. Milani investigated psychological and overall risk profiles in younger patients with heart disease, compared them with those of older patients (at least 70 years of age), and evaluated the effects of formal CRET programs in the younger patients following a heart attack or related event.

Compared with the older patients, the younger ones were more likely to be overweight and have higher cholesterol levels, but they had lower blood pressure, the authors report.

Younger patients also had higher scores for depression, hostility, and anxiety.

After CRET, young patients showed significant improvements in body weight, cholesterol levels, breathing, heart rate, and blood pressure, the results indicate.

Young patients also experienced marked improvements in anxiety, depression, hostility, and quality of life after CRET, the researchers note.

Elderly patients experienced similar, but less marked, improvements in most variables studied, the report indicates.

'These data support the importance of getting young patients following major cardiac events to be routinely referred to and vigorously encouraged to attend these CRET programs,' Lavie said.

'I believe that these data provide further support for the benefits of exercise training to improve overall psychological health,' Lavie added. 'We are currently evaluating the impact that these psychological factors have on mortality and whether this can be affected by reducing these adverse factors with CRET."

The fatty acid is called eicosapentaenoic acid (EPA). It's one of the disease-fighting omega-3 fatty acids.

In a study of more than 18,000 men and women, those who took high doses of EPA plus a cholesterol-lowering statin drug (either Zocor or Pravachol) were 19 percent less likely to suffer a variety of heart ailments, compared with those who took statins alone.

Antioxidant-rich Pecans Can Protect Against Unhealthy Oxidation (CLICK FOR MORE):

"A new research study from Loma Linda University (LLU) shows that adding just a handful of pecans to your diet each day may inhibit unwanted oxidation of blood lipids, thus helping reduce the risk of heart disease. Researchers suggest that this positive effect was in part due to the pecan's significant content of vitamin E.

'Plant foods, including pecans, are rich sources of phytochemicals that can have a unique effect on the body,' says LLU researcher Ella Haddad, DrPH, associate professor, department of nutrition, School of Public Health.

Pecans contain different forms of vitamin E -- known as tocopherols -- which protects fats from oxidation. Pecans are especially rich in one form of vitamin E -- gamma tocopherol.

'We found that eating pecans increased levels of gamma tocopherol concentrations in the blood and subsequently reduced a marker of lipid oxidation,' adds Dr. Haddad.

Oxidation of fats in the blood -- a process akin to rusting -- is detrimental to health. When the 'bad' cholesterol becomes oxidized, it is more likely to build up and result in arteriosclerosis.

These latest research findings on pecan's healthfulness were published in the latest issue of Nutrition Research, just released this week. They are from the second phase of a research project designed to evaluate the health benefits of pecans, according to Dr. Haddad. She analyzed blood samples from study participants (a total of 23 men and women between the ages of 25 and 55) who ate two diets: one that contained pecans and one that did not. Participants were randomly placed on either the American Heart Association's Step I diet or a pecan-enriched version of the Step I diet. (The pecan-enriched diet was similar to the Step I diet but replaced 20 percent of calories with pecans). After four weeks on one diet, they then switched to the other diet..."

People need to know that so they seek emergency help immediately for those symptoms. But some patients may have mistaken beliefs about heart attack differences in men and women, say Jill Quinn and Kathleen King of the University of Rochester’s nursing school in New York.

Quinn, PhD, RN, CS-ANP, is an assistant professor specializing in cardiovascular nursing. King, PhD, RN, FAAN, is a professor with a focus on women and heart disease.

Double Jeopardy: Obese Smokers at Higher Risk of Death [click for more]People who are both very obese and who smoke increase their risk of death by 3.5 to 5 times that of people of normal weight who never smoke, finds a study in the November issue of the American Journal of Preventive Medicine.

According to the study, 20 percent of obese adults in the United States smoke, which puts them at a higher risk of death caused by cancer and circulatory disease. The authors further found that, in general, being a current smoker was a far stronger risk factor for cancer death than being obese.

“Smoking has been known as a very strong risk factor for many cancers, particularly lung cancer, which is the most common site of cancer death,” said lead author D. Michal Freedman, Ph.D., of the Division of Cancer Epidemiology and Genetics at the National Cancer Institute.

The study surveyed more than 80,000 current and former radiologic technologists between the ages of 22 and 92 who completed a self-administered questionnaire in the period from 1983 to 1989. They all were followed through December 2002 and the number of deaths was reported.

The questionnaire collected information such as birth date, height, weight and smoking behavior. Participants’ body mass indexes were calculated from their weight and height A BMI of 30 to 34.9 was considered obese, and more than 35 was very obese.

Smoking behaviors were categorized by duration, intensity and current status. Freedman and her colleagues analyzed a measure that included both cigarettes smoked per day and duration of smoking. They found, in general, that more smoking or “pack-years” was related to a higher risk of death.

Also, in both women and men of all ages, the risk of death from circulatory disease increased with each additional increment in the BMI. When participants were obese and also current smokers, their risk of death from circulatory disease jumped even higher to an increase of 6- to 11-fold for those under age 65, compared to the participants of normal weight who never smoked.

SignOnSanDiego.com > Latest scanning device finds heart disease, and controversy, quickly [CLICK 4 MORE]
"
Coming soon to a medical center near you: a much-anticipated but controversial X-ray machine that can detect heart disease in five seconds.

Although the 64-slice CT scanner can be used to see other parts of the body, its most talked-about ability is to detect blockages in coronary arteries.

Highly precise, 3-D images show if a patient's symptoms, such as chest pain, are caused by heart disease and require an invasive procedure such as catheterization to correct.
Cardiologists say that the machine is not as reliable for someone with previously treated heart disease. The better option in those cases is to go straight to catheterization, they advise.

Limitations aside, doctors rave about how quickly the scanner can rule out serious cardiac complications.

More than 1,000 of the machines have been installed worldwide since their rollout two years ago. They got a celebrity boost when Oprah Winfrey underwent a cardiac check with the device on her TV talk show last year.

“Ever since Oprah, I've been bombarded by physicians in other parts of the country (and) even from Japan, France and Saudi Arabia” who want their patients to be scanned, said Dr. John Hauschildt of Rady Children's Hospital in Kearny Mesa, the first facility in the county to get the 64-slice CT scanner.

The machine is not without its critics. Some cardiologists worry that it will be overused, exposing people who have no symptoms or risk factors for heart.....

Coronary Artery Disease [FULL STORY]
"Coronary artery disease is a condition in which the inner walls of the heart's arteries become narrowed by an accumulation of plaque. Over time, as more plaque accumulates, the channel for blood flow narrows. Some parts of the heart muscle may not get enough oxygen, leading to a type of chest pain, called angina.

Eventually, the plaque can build up enough to completely block the flow of blood. More commonly, some of the plaque breaks loose. The body senses this as an injury and forms clots to "heal" the area. The clots can also block the flow of blood. In either case, the area of heart muscle fed by the part of the artery beyond the point of blockage is deprived of oxygen and dies. This is known as a heart attack, or myocardial infarction.

Heart disease is the leading cause of death in the U.S. The American Heart Association estimates 1.2 million men and women will have a heart attack this year. In 2003, heart attacks killed 221,000 Americans. Of those who survive, 25 percent of men and 38 percent of women will die within one year. Within six years of a heart attack, 18 percent of men and 35 percent of women will die..."

National Survey Shows Women Overlook Common Warning Signs Associated With Poor Blood Sugar Management, Raising the Risk for Diabetes and Heart Disease - MORE Forbes.com
For women, excess weight in the mid-section, frequent fatigue and carbohydrate cravings may be the warning signs of something more serious. A new survey commissioned by the not-for-profit National Women's Health Resource Center (NWHRC) showed that 75 percent of women ages 40-65 who had not been diagnosed with, but had a family history of diabetes or heart disease, reported that they experienced these symptoms. However, nearly one-third (32%) of all women surveyed did not know they could be signs of impaired insulin function, a key risk factor for type 2 diabetes and heart disease. The most common symptoms experienced were excess weight in the mid-section (62%), frequent fatigue (36%) and carbohydrate cravings (30%).

"When women who don't have diabetes hear the word 'insulin' they tune out because they think it doesn't apply to them.

Study Identifies Potential New Marker For Heart Failure Diagnosis, Prognosis....Harvard- Mass General Hospital...MORE
A collaborative study by researchers from Massachusetts General Hospital (MGH) and the University Hospital of Maastricht, The Netherlands, has identified a new candidate biomarker for heart failure with the potential of further improving the challenging task of diagnosing and predicting outcomes for patients with symptoms of heart failure, primarily shortness of breath. In the September 19 Journal of the American College of Cardiology, the investigators report that elevated blood levels of galectin-3, an inflammatory protein, can help diagnose heart failure and identify patients at risk of dying within 60 days. Another potential marker, apelin, did not prove to be useful.

"Heart failure is one of the most difficult diagnoses to make accurately, since it has numerous, varied symptoms, and signs that indicate heart failure are hard to detect," says James Januzzi Jr., MD, of the MGH Cardiology Division, the paper's co-lead author and principal investigator of the 2005 PRIDE Study, from which the data for the current report was generated. "It also is notoriously difficult to identify those heart failure patients at the highest risk of death, so biomarker screening to assist with prognostication has been studied and increasingly implemented over the past several years.............."
