DefiPace to help prevent heart rhythm problems after heart surgery
This study tests DefiPace in people who are having planned open-chest heart surgery (bypass and/or valve surgery) to see if it can help reduce certain post-surgery heart rhythm complications. Whether it’s usable depends on your planned procedure and specific health factors.
ViennaAges 18 years+ - NCT04695106RecruitingPhase 4
Blood Thinner and Heart Attack Prevention Study
This study tests whether taking dabigatran (a blood thinner) combined with ticagrelor (a blood clot preventer) is safe and effective for patients with irregular heart rhythm (atrial fibrillation) who recently had a heart attack and received a stent. The goal is to prevent future blood clots while minimizing bleeding risks.
Gdansk, Pomeranian VoivodeshipAges 18 years+ - NCT04664686Recruiting
Compare two heart-rhythm strategies after CRT for atrial fibrillation
This study looks at whether a “rate control” or “rhythm control” approach works better for people with CRT devices who still have atrial fibrillation. It aims to improve heart failure symptoms and help the heart pace more effectively.
LondonAges 18–85 - NCT04347187Recruiting
Long-term blood-thinner study for atrial fibrillation patients
This trial follows people with atrial fibrillation to see how long-term blood-thinning treatment affects outcomes over time. It may help determine which long-term approach best lowers stroke and clot risks for patients like you.
MoscowAges 18 years+ - NCT03907046RecruitingPhase 3
Blood thinner study to prevent stroke after brain bleed
This Phase 3 study tests whether a blood thinner (apixaban) can help prevent another stroke and support recovery after you’ve had a brain bleed. You would be assigned to a treatment group, and the study checks safety and whether strokes can be reduced without causing dangerous bleeding.
Birmingham, AlabamaAges 18 years+ - NCT03830320RecruitingPhase 1
PET scan to look for blood clots in the heart or lungs
This Phase 1 study uses a PET scan to detect blood clots (thrombosis) in specific groups of people. It’s testing how well the scan can find clots and how it should be timed with other heart or illness tests.
Boston, MassachusettsAges 18–85 - NCT03524222Recruiting
Home hospital care for adults after sudden illness
This trial tests whether certain adults can safely receive hospital-level care at home instead of staying in the hospital, using a home care team. It may help you recover in your own home if your condition fits their plan and you have support at home.
Boston, MassachusettsAges 18 years+ - NCT03376165Recruiting
Study heart rhythm problems after heart surgery
This trial looks at heart rhythm issues (especially atrial fibrillation) that can happen after certain heart procedures. It may help doctors better predict, prevent, or manage these rhythm problems after surgery.
LilleAges 18 years+ - NCT03308773Enrolling by invitation
Prevention program for people at risk of type 2 diabetes
This trial looks at a personalized prevention approach for people who are at risk of developing type 2 diabetes. It may help by targeting your specific health factors before diabetes starts.
Ages 18–100 - NCT02808260Recruiting
Tracking what predicts abnormal heart rhythms after pacemaker
This study looks for patterns that can predict an abnormal heart rhythm called SCAF in people who have a pacemaker or defibrillator. The goal is to help doctors recognize risk earlier and respond sooner if it happens.
Ottawa, OntarioAges 18 years+ - NCT01759225Enrolling by invitation
Registry study of people with heart and blood vessel disease
This is a registry (a study that collects health information) for people with certain heart and blood vessel conditions. It may help researchers better understand who has these diseases, how they are managed, and outcomes over time.
Tel AvivAges Any age - NCT07253974Recruiting
Atrial Fibrillation Stroke Recovery Study
This study follows people who had a stroke linked to atrial fibrillation (an irregular heartbeat) and are in a rehabilitation program. Researchers want to see how recovery goes and what helps patients improve.
BarcelonaAges 18–99 - NCT07775976Enrolling by invitation
Whole-heart checkup with a wearable heart monitor
This study looks at how well a wearable heart monitor and special software can check the health of your whole heart and assess your risk of future heart problems. It may help doctors create more personalized care plans.

Common questions
- Are there clinical trials for atrial fibrillation?
- Yes. Clin2 currently lists 541 recruiting atrial fibrillation studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a atrial fibrillation trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a atrial fibrillation trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
