New study tracks hidden heart rhythm disorder in stroke patients
NCT ID NCT06589700
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study follows 24 people who had a stroke and were recently diagnosed with atrial fibrillation (AF), a heart rhythm problem. Researchers want to see how AF changes over two years by monitoring heart activity, blood markers, and heart structure. The goal is to better understand AF progression in stroke survivors, which could lead to improved treatments and stroke prevention.
