Blood clotting markers and heart ultrasound in people with device-detected atrial fibrillation
Part of Heart & circulation clinical trials.
This study looks at blood clotting markers and heart ultrasound in people who have a heart device that detected brief episodes of irregular heartbeat (atrial fibrillation). It aims to understand how these markers relate to stroke risk.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are over 50 years old.
- You have a pacemaker, defibrillator, or implantable monitor that detects heart rhythm.
- Your device recorded at least one episode of atrial fibrillation lasting 30 seconds or more in the past year.
- You have never been diagnosed with atrial fibrillation on a standard ECG before.
- You are not taking blood thinners or certain antiplatelet medications (like aspirin plus clopidogrel) in the last 6 months.
- You are not pregnant, breastfeeding, or taking hormone replacement therapy or oral contraceptives.

This study follows patients who have a heart rhythm device (pacemaker, defibrillator, or resynchronization device) and have experienced brief episodes of fast irregular heartbeats detected by the device. The study compares treatment approaches to understand which helps patients stay healthier and feel better.
This study looks at stroke risk and blood clotting in people who have just been diagnosed with atrial fibrillation (AFib) that is not caused by a heart valve problem, and who have not yet taken blood thinners. It aims to better understand how blood clots form in this condition.
This study looks at early changes in the heart related to atrial fibrillation (AF) using health data and biomarkers. It aims to find better ways to predict or understand AF, especially around procedures like ablation or cardioversion.
This study looks at heart ultrasound pictures and heart-rhythm recordings to predict who may develop atrial fibrillation (AF) after a stroke or TIA. If you qualify, your results may help doctors better spot people at higher risk earlier.
This study looks at blood-related “clotting” signs and heart scan results in people with atrial fibrillation (AF) who are getting a catheter ablation. It may help doctors better understand AF and choose treatments more precisely.
This study tests a new blood thinner to prevent strokes and blood clots in people with atrial fibrillation (a common heart rhythm problem). You may qualify if you have atrial fibrillation and at least one risk factor for stroke, or if you've never taken a blood thinner before.
