Recruiting studies
- NCT05829317RecruitingPhase 4
Magnesium to prevent new atrial fibrillation in ICU patients
This trial tests whether giving magnesium can lower the chance of developing new irregular heartbeat (atrial fibrillation) in critically ill adults in the ICU. If you are at risk but do not already have this rhythm issue, magnesium may help prevent it.
Hamilton, OntarioAges 18 years+ - NCT04528511Recruiting
Studying new atrial fibrillation after heart attack
This study looks at how often atrial fibrillation happens soon after an acute heart attack, and who is most at risk. It may help doctors identify patients who need closer heart-rhythm monitoring after a hospital heart attack.
Kaifeng, HenanAges 18 years+ - NCT06715449RecruitingPhase 2/Phase 3
Testing empagliflozin after a stroke with unknown cause
This trial tests if a diabetes drug called empagliflozin can help the heart's left atrium work better in people who have had a stroke with no known cause. You may join if you are getting a heart monitor device implanted to look for hidden irregular heartbeats.
Cambridge, CambridgeshireAges 18 years+ - NCT05841056RecruitingPhase 3
Short amiodarone treatment to prevent new heart rhythm after surgery
This trial studies whether a short course of amiodarone started right after heart surgery can reduce problems from new-onset atrial fibrillation (a common fast heart rhythm) or flutter. It may help some patients avoid ongoing rhythm issues and improve recovery soon after discharge.
Hamilton, OntarioAges 18 years+ - NCT04045665RecruitingPhase 3
Blood thinner vs usual care for new heart rhythm after bypass surgery
This trial tests whether using a blood thinner in people with new, temporary atrial fibrillation after CABG (heart bypass surgery) can reduce harmful outcomes compared with standard treatment. It may help prevent stroke or other complications if your rhythm problem fits the trial’s timing and risk profile.
Little Rock, ArkansasAges 18 years+ - NCT04696081Recruiting
Atrial fibrillation treatment in people with active cancer
This trial studies atrial fibrillation (an irregular heartbeat) in adults who have active cancer. It looks at people whose atrial fibrillation started after their cancer diagnosis or returned after cancer diagnosis.
Caen, NormandyAges 18 years+ - NCT04964765Recruiting
3D heart mapping after early irregular heartbeat after surgery
This study uses 3D heart mapping to understand a specific kind of irregular heartbeat that can happen soon after cardiac surgery. It may help doctors better recognize what’s happening in the heart during the early recovery period.
Sankt PöltenAges 18 years+ - NCT05860894Recruiting
Study of new ICU atrial fibrillation
This trial looks at people who develop a new irregular heart rhythm called atrial fibrillation while in the intensive care unit (ICU). It tests an approach to help with that condition after critical illness, aiming to improve outcomes for those affected.
BesançonAges 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.
Kansas City, MissouriAges 18 years+ - NCT06275503Recruiting
Stroke Prevention Through Improved AFib Screening
This study tests a new way to find hidden atrial fibrillation (an irregular heartbeat) in people aged 75-76 in the Värmland region. If caught early, treatment can help prevent strokes.
StockholmAges 75–76 - NCT06363604Recruiting
Alcohol injection with ablation for persistent atrial fibrillation
This trial is testing a new approach to treat persistent atrial fibrillation (a type of irregular heartbeat) by combining standard catheter ablation with a special injection of alcohol (ethanol) into certain heart veins. It may help people whose symptoms haven't improved with medication.
Shanghai, Shanghai MunicipalityAges 18–85 - NCT06949319Recruiting
Stroke Risk and Blood Clots in New Atrial Fibrillation
This study looks at stroke risk and blood clotting in people who have just been diagnosed with atrial fibrillation (AFib) that is not caused by a heart valve problem, and who have not yet taken blood thinners. It aims to better understand how blood clots form in this condition.
Esbjerg, Region SyddanmarkAges 18 years+ - NCT06959121Recruiting
Treating AFib during open-heart surgery with a new device
This trial tests a new device used during open-heart surgery to treat atrial fibrillation (AFib) by delivering tiny, fast electrical pulses to the heart tissue. It is for people who are already having heart surgery and want to also treat their AFib at the same time.
St. Helena, CaliforniaAges 18–85 - NCT06730828RecruitingPhase 1/Phase 2
Amiodarone patch to prevent new irregular heartbeat after heart surgery
This trial tests a patch that releases amiodarone, a medicine that helps prevent a common irregular heartbeat after open-heart surgery. The patch is placed on the heart during surgery to stop new atrial fibrillation from starting.
Louisville, KentuckyAges 20–85 - NCT07018596Recruiting
New pulsed field ablation for paroxysmal atrial fibrillation
This trial tests a new type of heart procedure that uses gentle electrical pulses to fix abnormal signals in the upper chambers of the heart for people with a specific type of atrial fibrillation that comes and goes on its own. It may be an option if your AFib episodes stop within 7 days and medications haven't helped enough.
Prague, RoentgenovaAges 18–85 - NCT05955365RecruitingPhase 4
Single anticoagulant blood thinner after stent in atrial fibrillation
This trial tests whether taking a single “P2Y12 inhibitor” blood thinner (instead of multiple medicines) is safe and effective after you get a coronary stent. It’s for people with atrial fibrillation who need long-term blood thinning and have recently had a successful stent procedure.
HasseltAges 18 years+ - NCT04695106RecruitingPhase 4
Blood Thinner and Heart Attack Prevention Study
This study tests whether taking dabigatran (a blood thinner) combined with ticagrelor (a blood clot preventer) is safe and effective for patients with irregular heart rhythm (atrial fibrillation) who recently had a heart attack and received a stent. The goal is to prevent future blood clots while minimizing bleeding risks.
Gdansk, Pomeranian VoivodeshipAges 18 years+ - NCT06383975Recruiting
Two new treatments for AF that returned after first procedure
This trial tests two new treatments for persistent atrial fibrillation that came back after an initial procedure. One uses a targeted chemical injection, the other uses a special energy field to re-isolate the veins involved.
BrugesAges 18 years+ - NCT06983613Recruiting
New heart rhythm after PFO closure study
This study looks at whether closing a small hole in the heart (called a PFO) can cause new heart rhythm problems. It is for people who had a stroke caused by a PFO and are planning to have it closed.
PragueAges 18 years+ - NCT07574697Recruiting
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.

Common questions
- Are there clinical trials for atrial fibrillation new onset?
- Yes. Clin2 currently lists 20 recruiting atrial fibrillation new onset 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 new onset 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 new onset 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.
