...While this research could be useful for patients at higher risk for ischemia, we still need to nail down how exactly this drug is causing cells to rewire their metabolism,” Sheth said. “Our findings are very exciting, but so far we have only done animal trials and remain cautiously optimistic about applications in humans...
...trial raise the possibility that the danger of some diabetes complications may not be as great as earlier data has indicated and that doctors may be screening diabetes patients to no benefit. Reporting from a group of institutions in the U.S. and Canada, researchers involved in the Detection of Ischemia in Asymptomatic Diabetics (DIAD) study found that screening diabetes patients for heart risk fails to predict which patients are most likely to have a heart attack. DIAD also found that the risk of heart disease among diabetes patients may be exaggerated overall, according to the data published April...
...heart, and more than 9 million nuclear perfusion scans, which use mildly radioactive tracer molecules to measure how well the cardiac muscle is nourished. Improvements in computer processing power and software have made these tests more reliable and more conclusive than ever before. Stress tests, which help doctors detect ischemia, or lack of blood flow to the cardiac muscle, can be performed using either echocardiograms or nuclear scans. "Echocardiograms and nuclear perfusion scanning are the bread and butter of cardiac care," says Dr. Pamela Douglas, chief of cardiovascular medicine at Duke University Medical Center in Durham, N.C., and president...
...every blockage reduces blood flow. Sometimes the other blood vessels that nourish the heart can take up the slack--a situation that's more common than you might think. "We still don't know what to do with patients who have a number of moderate narrowings but no ischemia," says Dr. Roger Blumenthal of Johns Hopkins. "There are no data showing that taking them to the cath lab for stenting or angioplasty affects their outcome...
...study of women with heart problems suggest that sometimes it's better to be fit than thin. Active women, no matter how thin or fat, were much less likely to have a heart attack and other cardiac problems than women who didn't exercise, according to the Women's Ischemia Syndrome Evaluation. But weight does matter. Researchers in the ongoing Women's Health Study found that overweight and obese women--regardless of how regularly they exercised--were as much as nine times as likely to develop diabetes as women of normal weight. Bottom line? Get active and stay trim...
