Researchers have found that Viagra, commonly used to treat erectile dysfunction, may help prevent heart attacks and strokes in people who have stents keeping arteries open.A team from Queen's University in Canada found that the drug regulates a single enzyme in cells called PDE5. The enzyme helps platelets in the blood form clots.When clots form on stents, they can cause sudden, massive heart attacks and strokes, a news release on the study said.The team's findings will be published on-line this week in the international journal Proceedings of the National Academy of Sciences.
