Recruiting studies
- NCT05293080RecruitingPhase 3
Early heart rhythm treatment to help prevent stroke
This trial tests an early treatment approach for people who had a recent ischemic stroke (a stroke caused by a blocked blood vessel) and have an irregular heart rhythm called atrial fibrillation (AF). It aims to lower the chance of having another stroke by treating AF as early as possible after the stroke.
HamburgAges 18 years+ - NCT03968393RecruitingPhase 4
Blood thinner to prevent stroke after stress-related irregular heartbeats
This trial tests whether taking a blood thinner can lower the risk of stroke in people who had atrial fibrillation (an irregular heartbeat) that happened temporarily around a stressful illness or surgery. It looks especially at people at higher risk for stroke after that episode.
Los Angeles, CaliforniaAges 55 years+ - NCT07444320Recruiting
Testing new energy pulses for atrial fibrillation treatment
This trial tests a new way to deliver energy (FARAPULSE PFA system) to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to see if these new waveforms can safely and effectively stop AF symptoms and improve quality of life.
SplitAges 18 years+ - NCT06510556Recruiting
Testing a new mapping and ablation system for AFib
This study tests a new device (FARAFLEX) that uses pulsed field energy to treat atrial fibrillation (AFib). You may qualify if you have persistent or paroxysmal AFib symptoms and have not had a prior ablation.
BrusselsAges 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+ - NCT02932007RecruitingPhase 2
Chloroquine to treat ongoing atrial fibrillation symptoms
This trial tests whether chloroquine can reduce symptoms in people with persistent atrial fibrillation (AF), an irregular heartbeat that lasts longer than a week. It will also closely monitor heart rhythm and safety, since the medicine can affect the heart and other organs.
Tampa, FloridaAges 18 years+ - NCT06560047Recruiting
Early catheter ablation for atrial fibrillation with heart failure
This trial tests whether early catheter ablation (a procedure to fix irregular heartbeats) helps people who have both heart failure and atrial fibrillation. It looks at how this treatment affects your heart function and quality of life.
AalborgAges 18–80 - NCT06505798Recruiting
Ablation vs medication for heart failure with atrial fibrillation
This trial compares a procedure called ablation (using cold, heat, or electric pulses to fix irregular heartbeats) with standard medications to see which better treats heart failure in people who also have atrial fibrillation. It may help if your heart's pumping ability is reduced and you still have symptoms despite medications.
HalifaxAges 18 years+ - NCT06763549Enrolling by invitation
AI-powered wearable patch for heart and lung monitoring
This study tests an AI-powered wearable patch (the COR ECG) to see if it can better track heart and lung health. It may help doctors find problems earlier without needing bulky equipment.
Melbourne, FloridaAges 18 years+ - NCT06646601Recruiting
Garden-based program for heart and stroke recovery
This trial tests a preventive program that uses a therapeutic garden to help people with heart or blood vessel conditions. It looks at whether patients find the program helpful and easy to take part in.
GapAges 18 years+ - NCT07815119Recruiting
Comparing two heart imaging methods before a stroke-prevention procedure
This study compares two imaging methods (TEE and CCTA) used before a procedure to close a small pouch in the heart, which helps prevent strokes in people with atrial fibrillation. Participants will be randomly assigned to one method, and both groups will be checked after 3 months to see which imaging works better.
Shanghai, Shanghai MunicipalityAges 18 years+ - NCT06398366Enrolling by invitation
Heart tests to prevent another stroke
This study looks at how heart problems might cause strokes. If you had a stroke that doctors can't explain after many tests, this trial will do extra heart monitoring to find possible causes and help prevent another stroke.
Camden, New JerseyAges 18 years+ - NCT07224178Recruiting
Heart strain and stroke of unknown cause
This study looks at how well the left side of the heart pumps (called strain) in people who had a stroke without a known cause. It aims to see if this heart measurement can help predict future strokes or heart rhythm problems like atrial fibrillation.
Pittsburgh, PennsylvaniaAges 18 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+ - NCT05476991RecruitingPhase 3
Low-dose colchicine plus ticagrelor to prevent repeat stroke
This Phase 3 study tests whether low-dose colchicine added to ticagrelor (a blood-thinning medicine) helps prevent another ischemic stroke in people whose first stroke was caused by clogged arteries. It aims to lower the risk of repeat stroke after recovery from a recent event.
Paris, ParisAges 18 years+ - NCT07372716Recruiting
Blood thinner safety during cancer surgery
This trial studies the safety of managing blood thinners (like apixaban or warfarin) around the time of cancer surgery or procedures. It aims to help doctors understand how to best handle these medications to reduce risks.
OttawaAges 18 years+ - NCT06216769Recruiting
Pill-in-the-pocket blood thinners after AF ablation
This study tests a 'pill-in-the-pocket' approach for blood thinners after a catheter ablation for atrial fibrillation. Instead of taking a daily blood thinner, you may only take it when needed, which could reduce the risk of bleeding while still preventing strokes.
SeoulAges 19–89 - NCT04974151RecruitingPhase 4
Prevention trial for stroke risk in people with high blood pressure
This trial tests an approach to prevent first-time stroke and heart problems in people with high blood pressure who also have a specific genetic test result (MTHFR 677 TT). It may help by lowering risk before a first stroke happens.
Bengbu, AnhuiAges 45–74 - NCT04974138RecruitingPhase 4
Preventing first stroke in people with high-risk blood pressure
This trial tests whether a study medicine regimen can help prevent a first stroke in people with hard-to-control “high homocysteine” risk factors linked to a specific gene type. You may qualify if you have certain blood pressure levels, a specific MTHFR gene result, and related blood test findings.

Common questions
- Are there clinical trials for atrial fibrillation (prevention of stroke)?
- Yes. Clin2 currently lists 43 recruiting atrial fibrillation (prevention of stroke) 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 (prevention of stroke) 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 (prevention of stroke) 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.
