Recruiting studies
- NCT05452356Recruiting
Testing a phone-based care plan for people with heart conditions
This trial tests a phone app that helps deliver organized “care plans” for people with cardiovascular (heart/vessel) conditions. You might join to see if this phone-based support improves how care is delivered and helps you manage your condition.
London, OntarioAges 18 years+ - NCT05494034Recruiting
Monitoring heart rhythms after stroke to guide care
This study uses a small implantable heart monitor to track heart rhythm in people after an acute ischemic stroke or TIA. It aims to learn how often hidden heart rhythm problems show up, which could help doctors choose better stroke prevention treatments.
AthensAges 40–100 - NCT05532878Recruiting
Apixaban dosing study for people on peritoneal dialysis
This study checks how apixaban (a blood thinner) moves through the body in people who are on peritoneal dialysis and have non-valvular atrial fibrillation. It may help confirm the safest and most effective dosing for patients who have little or no remaining kidney function.
ShatinAges 18–80 - NCT05617456Recruiting
Test new ablation technology for treating irregular heart rhythm
This study tests advanced technology to improve how atrial fibrillation (AFib) is treated with a heart ablation procedure. It may help patients who are already advised to have AFib ablation by seeing how well the approach works in real clinical practice.
PisaAges Any age - NCT05643235Recruiting
Loop monitor to watch heart rhythms when starting a BTK inhibitor
This study checks how often abnormal heart rhythms happen when you start a BTK inhibitor (used for certain blood cancers). It uses a small implanted heart monitor to record your rhythm continuously before and after starting the medication, so doctors can detect and manage problems early.
New Hyde Park, New YorkAges 18 years+ - NCT05664308Recruiting
Watch-based heart rhythm monitoring after heart surgery
This study tests whether a connected watch can help monitor an irregular heart rhythm (atrial fibrillation) after heart surgery. It looks at people who develop new atrial fibrillation after surgery and compares how well monitoring works over the next 12 months.
Nantes, Loire AtlantiqueAges 18 years+ - NCT05717725RecruitingPhase 3
Pulsed heart ablation vs fake procedure for irregular heartbeat
This trial tests whether pulsed-field ablation (a targeted treatment meant to stop abnormal heart signals) works better than a sham, or “placebo,” ablation. It is for certain people with atrial fibrillation (AF) to see if symptoms and heart rhythm outcomes improve.
PragueAges 18 years+ - NCT05773768Recruiting
Care pathway study for newly diagnosed atrial fibrillation patients
This study looks at new care plans (“care pathways”) and how well they work, including cost and health outcomes. It may help by comparing whether a different follow-up approach after a new atrial fibrillation diagnosis leads to better care, especially for older adults.
GroningenAges 65 years+ - NCT05777551Recruiting
High-power short treatment for irregular heartbeat
This trial studies a specific heart-rhythm procedure that uses higher power for a shorter time to treat atrial fibrillation (AF), an irregular heartbeat. It may help some people control AF and reduce rhythm episodes, while doctors compare outcomes using their chosen approach.
ParisAges 18–80 - NCT05794464Recruiting
Safe tracking registry for people with Afib
This registry is collecting health information from people with atrial fibrillation (Afib) who are being considered for a procedure to restore normal rhythm. It aims to better understand safety and outcomes so future care can be improved.
Ostrava, Moravian-Silesian RegionAges 18 years+ - NCT05795842Recruiting
Detecting atrial fibrillation after stroke using a wrist monitor
This study checks whether a special wrist device can detect an irregular heartbeat (atrial fibrillation) in people who recently had a stroke with an unclear cause. It may help doctors find the cause earlier and tailor follow-up care.
Atlanta, GeorgiaAges 55 years+ - NCT05826665Recruiting
Study of heart rhythm mapping during AF ablation
This is an observational study that looks at how a special heart mapping system may affect the procedure and outcomes for people having ablation for persistent atrial fibrillation (AF). It may help doctors better understand what works best and how procedures turn out.
Jonesboro, ArkansasAges 18–80 - NCT05852704RecruitingPhase 3
Dapagliflozin to prevent irregular heart rhythm after bypass surgery
This trial looks at whether dapagliflozin (a diabetes medicine that helps the kidneys and heart) can lower the chance of atrial fibrillation, an irregular heart rhythm, after coronary artery bypass (CABG) surgery. If you’re scheduled for planned bypass surgery, this study may help reduce post-operative rhythm problems.
BrnoAges 18 years+ - NCT05891145Recruiting
Remimazolam to prevent irregular heartbeat after heart surgery
This trial tests whether a medication called remimazolam can help prevent atrial fibrillation—a common, irregular heart rhythm that can happen after surgery. It focuses on people having a specific planned type of heart bypass surgery and checks if the study medication reduces postoperative rhythm problems.
Yangzhou, JiangsuAges 50–70 - NCT05960721Recruiting
Low-dose blood thinner versus standard care after heart appendage closure
This study looks at whether a lower-dose blood thinner works as well as the usual recommended anti-clot treatment after a procedure that closes off the heart’s left atrial appendage. It may help reduce bleeding risk while still preventing dangerous blood clots.
Xi'an, ShannxiAges 18 years+ - NCT05961748Recruiting
Brain and heart illness registry for adults in China
This study is a registry that collects health information from adults who have certain new heart and/or brain conditions. It may help researchers understand how these problems occur together and improve future care planning.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06026345Recruiting
Affera heart procedure registry study
This registry collects information about people who have a heart procedure using the Affera platform. It helps doctors learn more about how well the procedure works in the real world.
BrusselsAges 18 years+ - NCT06055751Recruiting
Heart rhythm monitoring after aortic valve replacement
This trial studies people who had a heart valve procedure called TAVI and later had a heart rhythm problem. You will get a tiny heart monitor placed under your skin to track your heart rhythm over time and help doctors understand how common these problems are.

Comparing treatments for persistent atrial fibrillation
This study compares two treatments for persistent atrial fibrillation (AF) that lasts more than 7 days but less than 2 years: electrical cardioversion (a shock to reset your heart rhythm) versus catheter ablation (using radio waves to fix the heart's electrical pathways). It aims to find which option works better for patients like you.

Pulsed field ablation for atrial fibrillation
This trial tests a new method called pulsed field ablation to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to safely stop AF episodes by targeting specific areas in the heart, and may help people with paroxysmal (coming and going) or persistent AF who haven't had this procedure before.

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.
