SGLT2 inhibitor for atrial fibrillation, high blood pressure, and high blood sugar
This study tests whether a medication called an SGLT2 inhibitor (a type of diabetes drug) can improve the function of the upper left heart chamber in people who have paroxysmal atrial fibrillation, high blood pressure, and abnormal blood sugar levels. If you qualify, the trial may help your heart work better and reduce your risk of stroke.
Shanghai, Shanghai MunicipalityAges 18–80 - NCT06376916RecruitingPhase 3
Testing magnesium doses for fast heart rate in atrial fibrillation
This trial tests whether giving a higher dose of magnesium (4 grams) compared to a lower dose (2 grams) or a placebo can help control a fast heart rate during atrial fibrillation. It may help patients who are already receiving diltiazem.
Oak Lawn, IllinoisAges 18 years+ - NCT07106970Recruiting
Comparing two ablation approaches for persistent atrial fibrillation
This trial tests whether adding extra ablation lines to the standard pulmonary vein isolation procedure is more effective for people with persistent atrial fibrillation that hasn't been helped by medications. The goal is to improve symptoms like palpitations, fatigue, and shortness of breath.
BeijingAges 18–80 - NCT07753200RecruitingPhase 4
Comparing two blood thinners for atrial fibrillation and heart disease
This study compares two blood-thinning medicines, edoxaban and apixaban, to see which one is better at preventing strokes and bleeding in people who have both atrial fibrillation and coronary artery disease. If you're eligible, you may receive one of these standard treatments, and the trial could help find the safer option.
SeoulAges 19 years+ - NCT07275697RecruitingPhase 4
Weight loss drug and heart ablation study for AFib
This trial tests whether a weight loss medication (semaglutide) given before and after a first-time heart ablation procedure for atrial fibrillation can improve outcomes. It is for people who are overweight or obese and have certain related health conditions.
StockholmAges 18 years+ - NCT07173998Recruiting
Quality of life after heart surgery with irregular heartbeat
This study looks at quality of life in people who develop atrial fibrillation (an irregular heartbeat) after heart surgery. Researchers will ask you to fill out surveys to understand how this condition affects your daily life.

CT-guided heart imaging to guide treatment for atrial fibrillation
This trial studies whether using a special CT scan map of the heart muscle thickness can help doctors choose the best strategy during a cryoballoon procedure for paroxysmal atrial fibrillation. It may help improve effectiveness by tailoring treatment instead of using a standard approach.

Common questions
- Are there clinical trials for atrial fibrillation?
- Yes. Clin2 currently lists 546 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.
