Recruiting studies
- NCT07430956RecruitingPhase 3
Stroke prevention in atrial fibrillation without standard blood thinners
This trial tests a new medication to prevent strokes and blood clots in people with atrial fibrillation (an irregular heartbeat) who cannot safely take standard blood thinners. The drug works by blocking a different clotting factor, which may lower bleeding risks.
Dothan, AlabamaAges 18 years+ - NCT07430007Recruiting
Exercise and diet to reduce AFib burden
This study tests whether a program of exercise and healthy eating changes can reduce how often atrial fibrillation (AFib) happens and help you lose weight. It may be a good fit if you are overweight, have AFib, and are ready to make lifestyle changes.
Jyväskylä, Central FinlandAges 18–75 - NCT07403760Recruiting
Ablation for atrial fibrillation in patients 80 and older
This study investigates whether a catheter ablation procedure can improve wellbeing and reduce the risk of serious events for people 80 and older with symptomatic atrial fibrillation. The goal is to see if this treatment offers better outcomes than standard care in this age group.
BeijingAges 80 years+ - NCT07380620Enrolling by invitation
Step-by-step treatment for persistent atrial fibrillation
This trial tests a step-by-step treatment plan for people with persistent atrial fibrillation (a type of irregular heartbeat) who live in Southwest China. The goal is to find a better way to manage and possibly fix this heart condition.
ChongqingAges 18 years+ - NCT07358611Recruiting
Heart mapping-guided ablation for persistent atrial fibrillation
This trial tests whether using a special heart-mapping device during ablation (a procedure to fix irregular heartbeats) can improve outcomes for people with persistent atrial fibrillation and an enlarged left heart chamber.
BarcelonaAges 18 years+ - NCT07320560Recruiting
Personalized afib ablation using body surface mapping
This trial uses a special body-surface mapping technique to guide personalized ablation for persistent atrial fibrillation (afib). It aims to improve outcomes for people with an enlarged left atrium who have not had prior ablation.
BerlinAges 18 years+ - NCT05332457Recruiting
Beta-blocker effects on heart rate and exercise capacity in atrial fibrillation
This study looks at how taking a beta-blocker affects your resting heart rate during activity and how fit your heart and lungs are during an exercise test. It may help clarify whether the way the medication controls heart rate is linked to better exercise tolerance in people with persistent atrial fibrillation.
TaipeiAges 20 years+ - NCT07267949RecruitingPhase 2
Study of AP31969 for atrial fibrillation rhythm control
This study tests a new medication, AP31969, to control heart rhythm in people with atrial fibrillation. It compares the drug to a placebo to see if it can reduce how often AF episodes happen over time.
Plovdiv, PDAges 18 years+ - NCT07227532Recruiting
Testing a new catheter for atrial fibrillation treatment
This study tests a new catheter system, called Varipulse, to see if it's safe and effective for treating atrial fibrillation (AF), a heart rhythm problem. People with short-lasting AF who haven't been helped by medication may be able to join.
Phoenix, ArizonaAges 22 years+ - NCT07217067RecruitingPhase 2
Study of PKN605 for people with atrial fibrillation
This trial tests a new medicine called PKN605 for people with atrial fibrillation (irregular heartbeat). The goal is to see if it can safely help control heart rhythm. You will need to have had at least two AF episodes recently and meet other heart health criteria.
Tupelo, MississippiAges 18 years+ - NCT07187401RecruitingPhase 1/Phase 2
Study of a new RNA drug for PNH anemia
This trial tests an experimental RNA drug (ALN-CFB) for people with PNH who still have low red blood cell counts despite taking a C5 inhibitor. The drug aims to block a protein (complement factor B) to improve anemia.
Toronto, OntarioAges 18 years+ - NCT06322017Recruiting
Early vein isolation for atrial fibrillation in older adults
This study compares doing vein isolation soon after diagnosis versus usual care in people 75+ with new or early atrial fibrillation. The goal is to see if early treatment prevents the condition from getting worse and improves quality of life.
Nantes, Loire AtlantiqueAges 75 years+ - NCT07175428RecruitingPhase 2
Safety of a New Blood Thinner in AFib Patients
This study tests the safety of a new blood thinner for people with atrial fibrillation (AFib) who need long-term stroke prevention. If you qualify, the study will compare this medication to standard anticoagulation therapy.
Dothan, AlabamaAges 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.
Boston, MassachusettsAges 18–100 - NCT07156877Recruiting
Balloon Catheter Ablation for Atrial Fibrillation
This study tests a new balloon catheter that uses pulsed electric fields to isolate the veins that carry blood from your lungs to your heart. It may be a treatment option for people with atrial fibrillation who are scheduled for an ablation procedure.
BrugesAges 18 years+ - NCT07139314Recruiting
Timing of blood thinners after stroke clot removal
This trial is testing the best time to start blood thinners (anticoagulation) after emergency stroke treatment in people who have atrial fibrillation. It is for patients who had a certain type of bleeding in the brain after the procedure.
Ma’anshan, AnhuiAges 18 years+ - NCT07139301Recruiting
Timing of blood thinners after stroke clot removal in atrial fibrillation
This study aims to find the best time to start blood thinners after emergency clot removal in people with atrial fibrillation who had a stroke. It may help reduce the risk of another stroke or bleeding.
Ma’anshan, AnhuiAges 18 years+ - NCT07130773Recruiting
Comparing two catheter types for atrial fibrillation ablation
This trial compares two types of special catheters (thin tubes) used during a procedure called ablation to treat atrial fibrillation (irregular heartbeat). It aims to see which catheter works better during the procedure, and may help improve future treatments for people with heart rhythm problems.
Lugano, Canton TicinoAges 18 years+ - NCT02741349Recruiting
Checking stroke and bleeding risks in atrial fibrillation
This study looks at how to better predict both stroke risk and bleeding risk in people with atrial fibrillation. It may help doctors choose safer blood-thinner treatment and follow-up plans.
ParisAges 18 years+ - NCT07047235Recruiting
Targeted ablation for persistent atrial fibrillation
This trial is testing a specific approach to catheter ablation for people with persistent atrial fibrillation. It aims to improve how abnormal heart tissue is targeted to help restore a normal rhythm.
LondonAges 18 years+ - NCT05890664RecruitingPhase 3
Colchicine after shock treatment to stop atrial fibrillation
This trial tests whether colchicine given after cardioversion (a procedure that restores normal rhythm) helps keep the heart in normal rhythm afterward. It may help some people have fewer early returns of atrial fibrillation.
Bruderholz, Basel-LandschaftAges 18 years+ - NCT07036965Recruiting
Comparing two types of ablation catheters for atrial fibrillation
This trial tests two different catheters that use pulsed field energy to treat atrial fibrillation (a heart rhythm problem). It aims to find which one works better for people who need blood thinners but have a high risk of bleeding.
HangzhouAges 118 years+ - NCT06995391Recruiting

Common questions
- Are there clinical trials for atrial fibrillation, paroxysmal or persistent?
- Yes. Clin2 currently lists 469 recruiting atrial fibrillation, paroxysmal or persistent 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, paroxysmal or persistent 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, paroxysmal or persistent 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.
