Black men and women are twice as likely to die from coronary heart disease as white men and women, according to a study led by University of Alabama doctors. Death rates from heart attacks and coronary heart disease have fallen since the 1970s, but that statement rings far truer for whites than for blacks. Studies have shown a widening gap between whites and blacks in heart disease deaths and in heart-attack hospitalizations, and new research pins down just how deadly that difference is. A paper published in this week's Journal of the American Medical Assn.

It's no surprise that someone who has never smoked, who eats a Mediterranean diet and keeps a normal weight and who exercises regularly is healthy. How healthy? Chances of death from all causes is reduced by 80% over eight years. Pretty healthy. Those four healthy behaviors also protected against heart disease and the buildup of calcium deposits in the arteries, the researchers said. Those are the results of a multiyear study of more than 6,000 people led by Johns Hopkins University researchers and published online Monday in the American Journal of Epidemiology.

In an effort to combat heart disease, the No. 1 killer in the United States, the American Heart Assn. has awarded $1.3 million to UC San Diego's School of Medicine to serve as one of six national centers studying the molecular biology of the cardiovascular system. "Currently, most of our treatments for cardiovascular disease alleviate symptoms without addressing the fundamental basis of the problem," Kenneth Chien, UCSD associate professor of medicine, said in a press release Tuesday.

African American adults who were counseled to eat more produce and get more exercise as ways to reduce their chances of getting cancer and heart disease ate more fruit over the course of a month, researchers said. But they didn't exercise or up their consumption of vegetables, according to the work presented Wednesday at the American Assn. for Cancer Research meeting in Anaheim. The work was looking at the notion that a greater effect could be achieved if people understood that one risky behavior - a poor diet, for instance - is associated with the chance of developing multiple diseases, said Melanie Jefferson of the Medical University of South Carolina, the lead researcher.

The prognosis for Alzheimer's patients nowadays is still not good. Cognex, the one drug approved to treat the condition, only relieves symptoms. But, according to Carl W. Cotman, a prominent psychobiologist who directs UC Irvine's research into Alzheimer's, efforts toward understanding the disease "are going like gangbusters. It's an amazing rate of progress." Drugs that may slow the disease are being tested.

Paul W. Ewald's best thinking started with an attack of diarrhea on a field trip to Kansas. A zoologist, he was studying the social habits of sparrows. But during that ordeal 24 years ago, he had time to ponder other things: Was his personal predicament simply the havoc of a germ bent on spreading itself around? Or was his body trying to flush away the germ? Was this the evolutionary adaptation of an invader or the evolved human defense against it?

Here is a glossary of terms frequently used in discussions of cardiovascular disease and risk factors for that illness. Also included are definitions for a variety of the fiber foods often mentioned in relation to this disease and its prevention. Atherosclerosis: A disease that begins early in life with the formation of cholesterol-containing plaque or fatty streaks on the inner walls of the arteries, eventually narrowing them and inhibiting blood flow.

A healthier lifestyle may go a long way in reducing the risk of erectile dysfunction, a study finds, while another paper discovers that men who have the condition may also have a greater risk of cardiovascular disease. A meta-analysis published online Monday in the journal Archives of Internal Medicine looked at how lifestyle changes and medication to treat cardiovascular risks affected erectile dysfunction. In six studies that included 640 participants, four dealt with lifestyle changes, and two with the use of statins.

Scientists have linked cardiovascular disease to an age-related breakdown of telomeres, repetitive strings of DNA on the ends of chromosomes. Every time a cell divides, a bit of the telomere is lost. Ultimately, when all the telomere is gone, the cells are unable to divide. Previous research has shown that cancer cells are able to prevent the telomeres from being shortened, and are thus able to continue dividing indefinitely. A team from Geron Corp. reports in the Proceedings of the National Academy of Sciences that blood vessel cells involved in atherosclerosis have shortened telomeres, suggesting that they have prematurely aged for an as-yet-unknown reason.

Sweet potatoes are often regarded as a healthier alternative to the white potato, which has been recently maligned as “Public Enemy No. 1” in America’s battle of the bulge. Some would even say that sweet potatoes are to white potatoes what brown rice is to white. But in a head-to-head comparison, these two tubers are seemingly very similar. In a 100-gram portion, the white potato has 92 calories, 21 grams of carbs, 2.3 grams of dietary fiber, 2.3 g of protein and 17% of the recommended daily value of vitamin C. The same amount of sweet potato, on the other hand, has 90 calories, 21 grams of carbs, 3 grams of fiber, 2 grams of protein, 35% of the recommended daily value of vitamin C and 380% of the daily recommended value of vitamin A. Importantly, both have won Vegetable of the Month designations from the Centers for Disease Control and Prevention.
