...doctors are not recommending that anyone go out and gulp aspirin for good health. The drug can have unpleasant and even dangerous side effects, including ringing in the ears and blurred vision, as well as stomach bleeding. A more serious problem is hemorrhagic stroke, caused not by a clot blocking the brain's blood vessels but by vessels that rupture. Moreover, prostaglandins appear to work in opposing pairs. The ones that promote clot formation, for example, are countered by partners that do the opposite. Too much aspirin can therefore cause the very problems that lower doses relieve...
Previous studies have shown that aspirin can reduce the risk of heart attacks by interfering with the clotting of blood. Most heart attacks occur when blood vessels are narrowed and there is difficulty with blood flow. A blood clot may then develop in the vessel and block...
...heart drug hit the market in 1987 in a blinding flash of pitchmen, promotion and public relations hoo-ha. The product of biotech breakthroughs, TPA was touted as clearly superior to the competition, a clot-busting drug called streptokinase, on the market for 15 years. Though TPA (for tissue plasminogen activator) is 10 times as expensive as the older drug, the majority of U.S. doctors bought the pitch, and the new drug became the favored method of breaking up clots in heart-attack victims. Then last week an international team of researchers reported what some doctors had suspected all along...
...well-developed case of heart disease. Eventually the narrowing arterial passage could be blocked by a blood clot or by a spasm that constricts and closes the artery. That could cut off the blood supply to his heart, causing possibly fatal damage to its muscle. In short, he is a prime candidate for heart attack, which annually strikes 1.5 million Americans, killing half a million of them. (Women as well as men are vulnerable to heart disease, though usually later in life...
Stress, Benson explains, brings on a rise in blood pressure and spurs the release of catecholamines, substances that increase the tendency of blood to clot and make arteries more vulnerable to spasm. Over time, these changes play an important role, many doctors believe, in the progression of heart disease. However, Benson has shown, the changes can be largely counteracted by the "relaxation response" that follows 15 minutes of meditation...
