Women wait longer for emergency heart treatment
In a heart attack, the saying goes, "Time is muscle." The faster a person gets treated, the better his or her chances of survival and recovery. But a new study finds that women who have heart attacks wait longer than men to receive an emergency procedure that can re-open clogged blood vessels and restore blood flow to the heart muscle.  more

Study links polycystic ovary syndrome with early vascular changes of heart disease
Polycystic ovary syndrome (PCOS), a disorder characterized by metabolic and endocrine abnormalities, affects millions of women in the United States alone and endangers their hearts by causing early buildup of calcium in coronary arteries, researchers at the University of Pittsburgh's Graduate School of Public Health report in the November issue of the Journal of Clinical Endocrinology and Metabolism.  more

Study reveals link between cardiovascular risk and cognitive decline
Elderly people with the metabolic syndrome -- a constellation of cardiovascular risk factors including excessive fat around the abdomen, high blood pressure, and high blood glucose levels -- are at greater risk for cognitive impairment and decline than those without the syndrome, according to a study led by a University of California, San Francisco (UCSF) researcher at the San Francisco VA Medical Center (SFVAMC). more


Abdominal fat decreases, insulin action improves when elderly take hormone
In a six-month study of elderly people, researchers at Washington University School of Medicine in St. Louis found that the hormone dehydroepiandrosterone (DHEA) significantly reduced abdominal fat and improved insulin action. This finding suggests that DHEA may be able to counter the increase in abdominal fat and accompanying increased risk for diabetes that very often occurs as we grow older.  more

Shp-2 tyrosine phosphatase a new target for control of obesity

No increase in deaths or hospitalizations for heart failure patients who have a pulmonary artery catheter
The pulmonary artery catheter (PAC), a device that measures pressures and flows in the heart, is frequently used to diagnose, monitor, and guide treatment of congestive heart failure and other conditions. However, use of the PAC has been controversial with varying opinions as to its risk and benefits. New findings from a multi-center study supported by the National Heart, Lung, and Blood Institute (NHLBI) of the National Institutes of Health show that the PAC did not significantly increase or decrease deaths or the number of days hospitalized in patients with severe heart failure. more
