New study tracks bleeding risks and Pill-Taking habits in heart patients
NCT ID NCT07458191
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study watches 800 adults with nonvalvular atrial fibrillation (a type of irregular heartbeat) who are starting the blood thinner apixaban for the first time. Researchers will track how often serious or minor bleeding occurs and how well patients stick to their medication schedule over six months. The goal is to better understand the real-world safety and adherence to this common treatment.
