Low doses of blood-thinning drugs are highly effective in reducing the risk of strokes caused by abnormal heartbeats, a study confirms. Such strokes afflict 75,000 Americans annually. In March, a major study found that a single daily aspirin tablet dramatically reduced strokes triggered by atrial fibrillation, abnormally rapid beating of the heart's upper chambers.

Infections commonly precede strokes and may trigger the strokes by altering the body's blood-clotting system, according to a USC study published this month in the journal Stroke. Neurologist Sebastian Ameriso and his colleagues evaluated 50 patients consecutively hospitalized for strokes and found that 17, or 34%, had had infections during the previous month. In most cases, the infection was a relatively mild upper respiratory tract infection.

Texas closer Hideki Irabu was hospitalized Monday at Kansas City, Mo., with small blood clots in his lungs. Irabu was taken to St. Luke's Hospital by assistant trainer Ray Ramirez after complaining of chest pains and shortness of breath. He is expected to be hospitalized for two to three days before returning to Texas. Irabu was given medication and blood thinners to dissolve the clots and was scheduled for additional tests to determine where the blood clots formed.

New evidence confirms that chronic smokers, including those who look and feel healthy, undergo activity in their bloodstreams that can lead to excessive clotting and possibly to heart attacks, researchers said Monday. Habitual smoking causes excessive interaction of the blood components that trigger clotting, said scientists in a study published Monday in Circulation, an American Heart Assn. journal. The formation of blood clots in arteries serving the heart muscle can result in a heart attack.

The Food and Drug Administration on Tuesday approved a new drug that quickly dissolves blood clots to prevent permanent damage following a heart attack. The drug, called anistreplase, is the third clot-dissolving drug to be approved. But its advantage is that it can be administered in five minutes or less while the other two must be administered continuously for one to three hours, according to SmithKline Beecham, which will market the drug as Eminase.

For more than 50 years, warfarin has been used to prevent dangerous blood clots in people with a variety of medical conditions. But it's not an easy drug to take. The levels circulating in the blood can change rapidly depending on other medications, food, activity and illness; and frequent blood tests are required to make sure the dosage is adequate. And the drug, which is also used as rat poison, can be dangerous in high doses.

The common practice of packing hundreds of airline passengers into tight quarters without much legroom spawned the term "economy-class syndrome" to describe the blood clots that can form in the legs during prolonged periods of inactivity. While the syndrome is linked most often to flying, the condition can occur in any situation where people are cramped for hours in tight quarters, such as a tank or other military vehicles on the battlefield.

An expensive drug used to dissolve blood clots in heart attack victims is no more effective than a competing drug that costs one-tenth as much, a large Italian study of TPA and streptokinase released Thursday in Florence shows. The long-awaited study, involving 19,000 patients, is the largest study ever to directly compare the drugs in heart attack victims.

A widely used new blood thinner that is routinely given to heart patients after angioplasty appears in rare cases to trigger a deadly blood disease. The drug, called clopidogrel (trade named Plavix) prevents blood clots and has been taken by more than 3 million people worldwide since its introduction two years ago. For the first time, doctors have linked the medicine to thrombotic thrombocytopenic purpura, or TTP, a dangerous form of anemia.

In the 1950s and 1960s, surgeons devised operations that revolutionized the treatment of peripheral vascular disease, a condition in which the arteries in the pelvis and legs are narrowed by a buildup of cholesterol and calcium clots in the vessel. The new advance was to install artificial blood vessels made of Dacron or to use one of the patient's veins to bypass the clots. These procedures prevented amputations and improved the lives of thousands of patients.
