Two senators called on the Pentagon on Wednesday to investigate the military's use of a largely experimental blood-coagulating drug that doctors inject into wounded troops to control bleeding, but which has been linked to unexpected and potentially deadly blood clots. Sen. Barbara A. Mikulski (D-Md.) sent a letter to Dr. William Winkenwerder Jr., assistant secretary of Defense for health affairs, asking him to launch an investigation into use of the drug, called Recombinant Activated Factor VII.

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.

A new, easier-to-use blood-thinning pill offers the first potential alternative in 50 years to warfarin, the standard treatment given to millions of people to prevent blood clots, researchers report today. The new drug has been tested in 17,000 patients for a number of uses and has been shown to work as well as or, in some cases, better than warfarin at preventing dangerous clots, the researchers said.

Reduced air pressure and oxygen levels do not appear to promote the formation of deadly blood clots during long commercial flights, an ailment sometimes called "economy class syndrome." The findings seem to bolster the widely held belief that clots develop in otherwise healthy people mainly because they are sitting in cramped quarters that slow blood flow, especially in the legs, not because of cabin environment.

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.
