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.

At least 200,000 deaths due to heart disease and stroke can be prevented each year by quitting smoking, controlling blood pressure and cholesterol, and taking aspirin when recommended by a physician, according to the U.S. Centers for Disease Control and Prevention. In a study  published Tuesday in the CDC's Morbidity and Mortality Weekly Report , researchers found that the rate of avoidable deaths from cardiovascular disease had dropped 29% from 2001 to 2010. However, researchers found the pattern of decline differed by age, race and state of residence.

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.

These days, thanks to advances in treatment and detection, millions of women survive breast cancer.   But surviving the disease doesn't necessarily mean the entire battle is over, a population-based study of breast cancer survivors in Sweden and Denmark, published Wednesday in the New England Journal of Medicine , seems to suggest. Assessing a total of 2,168 women whose breast cancer was treated with radiation therapy between 1958 and 2001, a team of researchers found that women's chances of having a major coronary event - a heart attack, bypass surgery or heart disease death - rose in proportion with the radiation dose they received, even at the lower doses of radiation delivered in newer treatments.

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.

The differences in men and women's hearts may not be limited to problems of the small and large arteries. Sudden cardiac arrest and how it's predicted may play out differently by gender as well. In the U.S., sudden cardiac arrest claims around 250,000 lives each year, which is about 30% of the total deaths from cardiovascular disease. In sudden cardiac arrest, the heart's electrical activity becomes disrupted or chaotic, preventing the organ from beating. Without immediate treatment by an external defibrillator or cardiopulmonary resuscitation, the victim will die; the mortality rate is 95%. In a heart attack, blood flow to the heart muscle is restricted, causing damage to the muscle.

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.

In a finding certain to put new pressure on the purveyors of sugary foods and drinks, a worldwide analysis shows that regardless of its effect on obesity, the ebb and flow of sugar in a country's diet strongly influences the diabetes rate there. The new study provides compelling evidence that obesity isn't driving the worldwide pandemic of Type 2 diabetes as much as the rising consumption of sugar - largely in the form of sweetened sodas, experts said. Increases in sugar intake account for a third of new cases of diabetes in the United States and a quarter of cases worldwide, according to calculations published Wednesday in the journal PLOS ONE. In the 175 countries studied, a 150-calorie daily increase in the availability of sugar - about the equivalent of a can of Coke or Pepsi - raises the prevalence of Type 2 diabetes by 1.1%, a research team from Stanford University and UC San Francisco found.

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.
