NCT ID NCT00465218
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looked at 70 people who had a tissue heart valve replacement. It compared two common blood-thinning treatments (high-dose aspirin alone vs warfarin plus low-dose aspirin) to see which one better prevented tiny blood clots from traveling to the brain. Researchers used ultrasound to detect these clots and also measured how well the treatments affected platelet function.
