Antiplatelet Therapy to Prevent Stroke in African Americans

Completed · Phase 4

Conditions studied: Stroke, Cerebral Infarction

In brief

The African-American Antiplatelet Stroke Prevention Study is designed to prevent recurrent strokes by administration of aspirin or ticlopidine. The study also provides community information on reducing risk of stroke and recognizing the symptoms of stroke. The study involves more than 50 participating hospitals located throughout the United States. Study medication is provided free of charge, and a transportation stipend is available for those in need.
