The purpose of this study is to determine the safety and effectiveness of the combination of low-dose aspirin and a medication called clopidogrel (also known by the brand name Plavix®) in reducing the risk of stroke, heart attacks and other complications in patients who have just had a TIA or minor ischemic stroke.
Patients who have had a TIA have a higher risk of having a major stroke. Recognizing and treating TIAs can reduce the risk of a stroke. Often, medication to prevent blood clots from forming is used to prevent a stroke in patients with blockage of one of the arteries in the brain. Low-dose aspirin has been shown to be effective in preventing strokes and heart attacks in patients who have had a TIA. Clopidogrel is another medication that is used to prevent strokes and heart attacks in patients at risk for these problems.
