Blood test could predict dangerous heart rhythm disorder
NCT ID NCT06735001
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aims to find unique substances in the blood (biomarkers) that are only present in people with atrial fibrillation, a common heart rhythm problem. Researchers will compare blood samples from 400 patients with AF to those without, and track changes over time. The goal is to develop a simple test that can predict who is at risk for AF or its return, allowing for earlier and more personalized prevention.
