Gene test could personalize stroke prevention

This study looks at whether genetic testing can help doctors pick the right antiplatelet medicine for people who have had a stroke or mini-stroke. About 350 patients will be randomly assigned to either standard care or a genetic test that checks if a common drug, clopidogrel, is likely to work for them. If the test shows the drug may not be effective, patients will receive alternative medications. The goal is to see if this personalized approach reduces the chance of another stroke or heart problem over the next year.
