> THE QUESTION The arsenal of drugs available to

> prevent strokes includes aspirin,

cholesterol-lowering statins and the blood pressure

drugs known as ACE inhibitors. Each has been shown to

work, when taken separately. Might combinations of

these drugs ratchet up their

> effectiveness?

>

> THIS STUDY analyzed data on 179 people hospitalized

> for a stroke caused by a blood clot or obstruction.

Those who had been taking aspirin, a statin and

> an ACE inhibitor had less-severe strokes than did

> people who were taking aspirin alone, aspirin and a

statin, aspirin and an ACE inhibitor or none of

>

> the drugs. About 65 percent of those taking the

> three drugs showed neurologic improvement by the

time they were discharged, compared with 45

> percent of those in the aspirin/ACE inhibitor group,

> 43 percent for the aspirin/statin group, 38 percent

for aspirin alone and 33 percent of those taking none

of the drugs. People on the triple treatment also were

able to function better when discharged and spent

somewhat less time in the hospital than the others.

> WHO MAY BE AFFECTED BY THESE FINDINGS? People taking

> preventing a stroke. High blood pressure, diabetes

> and heart disease are

> among the stroke risk factors that often are treated

> with medication. In the

>

> United States, someone has a stroke about every 45

> seconds.

> CAVEATS The findings have not been confirmed by a

> large-scale, randomized

> study. Information on how long the participants had

> drugs was not available. The analysis did not

> consider other medical

> conditions that may have affected participants'
