Personalized blood thinners could cut stroke risk
NCT ID NCT06269432
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether using a blood test to guide antiplatelet medication can reduce the risk of a second stroke. People who have had a non-cardioembolic ischemic stroke and are already taking aspirin will be assigned to either continue standard aspirin or switch to a different antiplatelet drug based on their test results. The goal is to see if personalized treatment lowers the rate of blood clot-related events within 30 days.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- aspirin, clopidogrel, ticagrelor
- What this could lead to
- If successful, this approach could help doctors choose the right antiplatelet drug for each stroke patient, potentially lowering the chance of another stroke or heart attack.
- What could go wrong
- This is a single trial with 1,224 participants, and results may not apply to all stroke patients. There is also a risk of bleeding with antiplatelet drugs, which the study will monitor.
