...Three drugs given to heart-attack victims -- magnesium, nitrates and captopril (the drug just found to be good for diabetics' kidneys) -- are surprisingly ineffective. Still worth taking: aspirin, clot dissolvers and beta blockers...
...Journal of Medicine reported that when you're dreaming, the sympathetic nervous system, which helps the body react to emergencies, is twice as active as it is when you're awake. Your heart beats faster, your blood pressure goes up, and your blood can get stickier, so it can clot and cause a heart attack. On the other hand, waking up isn't so great either. Heart attacks occur more often in the morning than at any other time...
Elsewhere, researchers are discovering that a high-fat diet plays an even nastier role in heart trouble than previously thought. Besides raising cholesterol levels slowly over time, fat-rich meals can send the body's blood- clotting system into overdrive and make blood dangerously sludgy within a matter of hours, thus elevating the risk of a heart attack. The fatty foods apparently trigger production of factor VII, a blood-clotting substance, which in turn sets off a massive chemical reaction. The good news is that switching to a low-fat diet promptly eliminates the increased risk of an artery-plugging...
Atrial fibrillation, which affects up to ten percent of people over 80, results from uncoordinated contraction of the two upper chambers of the heart. Irregular blood flow results, causing blood to pool in the chambers and clot. Strokes can then occur if the clots travel around the blood vessels and block blood flow...
Such charges dismay Dr. Elsa-Grace Giardina, a cardiologist at Columbia- Presbyterian Medical Center. "I would like to think that we treat everybody equally," she says. But her survey of medical literature tells her otherwise. "Women don't get thrombolytic therapy (blood-clot dissolvers like streptokinase) as often as men, they don't get coronary angiography or angioplasty, and they don't get bypass surgery as often...
