Viagra may prevent heart attacks, strokes

The drug is usually used to treat erectile dysfunction. But a group of researchers in Canada say it may help prevent heart attacks and strokes in people who have stents by keeping their arteries open.

A clot on a stent can lead to heart attack or stroke. Findings show Viagra was able to regulate an enzyme in cells that helps platelets in the blood form clots.
