Summary
This study looks at the best time to start blood thinners in people with atrial fibrillation who had a stroke and emergency treatment to open a blocked artery. About 438 participants will be randomly assigned to start blood thinners within 4 days or between 5-14 days after the stroke. The goal is to see which timing better prevents another stroke, major bleeding, or death.
