Genetic Study of Atrial Fibrillation and Heart Function Recovery
This study looks at genetic factors in people with atrial fibrillation (an irregular heartbeat) and weak heart function to understand why some people's hearts recover after treatment and others don't. Researchers will collect blood samples and medical information to identify genetic patterns.
LondonAges 18 years+ - NCT07607093Recruiting
Early rhythm control for atrial fibrillation with tricuspid valve leakage
This trial tests whether treating atrial fibrillation (an irregular heartbeat) early helps patients who also have tricuspid regurgitation (leakage in a heart valve). Researchers want to see if controlling the heart rhythm early can improve outcomes for people with both conditions.
Seoul, SeoulAges Any age - NCT07618741Recruiting
Improving AF Ablation Outcomes in Patients with Obesity
This study tests whether special care strategies can help obese patients have better results after a catheter ablation procedure for atrial fibrillation (a heart rhythm problem). Catheter ablation uses heat or cold to fix the irregular heartbeats.
TaipeiAges 20 years+ - NCT07654634Enrolling by invitation
Precision blood thinning therapy study
This trial tests personalized blood thinner treatment for people who need long-term anticoagulation for conditions like atrial fibrillation or blood clots. The goal is to find the safest and most effective dose for each patient.
Changsha, HunanAges 8 years+ - NCT07633548Enrolling by invitation
Simplified sedation protocol for heart rhythm ablation
This trial tests a streamlined sedation approach during pulsed-field ablation, a newer technique to treat irregular heartbeat (atrial fibrillation). Researchers want to confirm it's safe and practical.
CaenAges 18–80 - NCT07339007Enrolling by invitation
Validating a heart ultrasound training program for family doctors
This study tests whether a training program helps family doctors use a focused heart ultrasound (FoCUS) to assess patients. If you need a heart ultrasound as part of your regular care, you may be able to join.
Barcelona, CataloniaAges 15 years+ - NCT07283666Enrolling by invitation
Heart care quality program for AFib and heart failure
This trial aims to improve care for people with atrial fibrillation (a type of irregular heartbeat) or heart failure with reduced pumping strength. It focuses on making sure you get the right treatments based on your health history and recent visits to a heart doctor.
New York, New YorkAges 18–90 - NCT07154303Enrolling by invitation
Testing smartphones to detect irregular heart rhythm
This trial tests if smartphones and their accessories can detect a specific type of irregular heart rhythm called atrial fibrillation. If you have a form of atrial fibrillation or a normal heart rhythm, you may help see how well these devices work.
Hong KongAges 22 years+ - NCT07095634Enrolling by invitation
Heart risk study for Crohn's and colitis patients
This study looks at heart health in people with Crohn's disease or ulcerative colitis. It aims to understand the risk of heart problems over 2 years.
San Donato Milanese, MilanAges 16 years+ - NCT06789588Enrolling by invitationPhase 3
Better warfarin therapy for atrial fibrillation
This study tests a better way to manage warfarin (a blood thinner) for people with atrial fibrillation (an irregular heartbeat). The goal is to improve treatment and help prevent stroke.
Recife, PernambucoAges 18 years+ - NCT06583395Enrolling by invitation
Meditation retreat study with fitness tracker
This trial studies people attending a 7-day meditation retreat to see how meditation affects well-being. You will wear a fitness tracker and answer surveys.
Palm Desert, CaliforniaAges 21 years+ - NCT06211413Enrolling by invitation
Tracking heart issues in CLL patients on BTK inhibitors
This study watches for high blood pressure and irregular heartbeats in people with CLL who are starting a type of targeted therapy called a BTK inhibitor (acalabrutinib or zanubrutinib). Researchers will use a smartwatch and blood pressure cuff to monitor your heart health at home.
Philadelphia, PennsylvaniaAges 22 years+ - NCT05775354Enrolling by invitation
Early heart disease check-in in adults age 50–80
This study aims to improve early detection of heart and blood vessel problems by adding further research after routine care. It may help you by making sure your heart risk is monitored more closely, if you’re eligible and agree to the additional steps.
UtrechtAges 50–80 - NCT05305612Enrolling by invitationPhase 4
Blood thinner timing during heart procedures to protect against clots
This study compares the best way to give blood thinners around certain heart procedures (TEER or left atrial appendage closure). It aims to lower the risk of dangerous clots and bleeding during and after the procedure.
GdanskAges 18 years+ - NCT05236556Enrolling by invitation
Tracking how providers use oral blood thinners for AF
This study looks at how often and how well doctors use oral blood-thinner medicines for people with atrial fibrillation (AF) or atrial flutter (a related heart rhythm problem). It aims to see whether “provider profiling” (using clinic patterns to guide improvements) can support safer, more consistent use of these medicines.
Jacksonville, FloridaAges 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 - 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 548 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.
