How exercise changes structure and function of heart
For the first time researchers are beginning to understand exactly how various forms of exercise impact the heart. Massachusetts General Hospital (MGH) investigators, in collaboration with the Harvard University Health Services, have found that 90 days of vigorous athletic training produces significant changes in cardiac structure and function and that the type of change varies with the type of exercise performed. Their study appears in the April Journal of Applied Physiology.

JAMA article looks at data-sharing in clinical trials for heart disease
NEW YORK (April 9, 2008) -- How and when to share clinical trial data for heart studies -- including when to suspend a study -- is vitally important to physician-scientists and regulators as an increasing number of clinical trials evaluate new treatments. This issue is explored in the April 9 Journal of the American Medical Association (JAMA) in a commentary article authored by Dr. Jeffrey S. Borer of NewYork-Presbyterian Hospital/Weill Cornell Medical Center and Drs. David J. Gordon and Nancy L. Geller -- both of the National Heart, Lung and Blood Institute (NHLBI).

WHI follow-up study: Risks of long-term hormone therapy continue to outweigh benefits
New results from the Women's Health Initiative (WHI) confirm that the health risks of long-term use of combination (estrogen plus progestin) hormone therapy in healthy, postmenopausal women persist even a few years after stopping the drugs and clearly outweigh the benefits. Researchers report that about three years after women stopped taking combination hormone therapy, many of the health effects of hormones such as increased risk of heart disease are diminished, but overall risks, including risks of stroke, blood clots, and cancer, remain high. The WHI is sponsored by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health (NIH).

Exercise testing may help predict seriousness of mitral regurgitation
NEW YORK (Dec. 11, 2007) -- In as many as one in five people over age 55, when the heart contracts to send blood around the body, some degree of backward leakage occurs across the mitral valve, a condition known as mitral regurgitation (MR). When sufficiently severe, MR causes buildup of blood in the lungs, leading to difficulty in breathing (dyspnea, or shortness of breath), a serious condition called congestive heart failure. MR also can cause heart rhythm irregularities (arrhythmias) such as atrial fibrillation, which can lead to strokes and other problems, and ventricular tachycardia, which can cause sudden death.
