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+ - NCT06657404Recruiting
Modified 'Pills-in-the-Pocket' strategy for AF after ablation
This study tests a modified 'pills-in-the-pocket' approach—taking antiarrhythmic drugs only when symptoms occur—for people with non-valvular atrial fibrillation (AF) who still have arrhythmias lasting over 24 hours after their first catheter ablation. It aims to see if this strategy can safely control symptoms without needing daily medication.

Changsha, HunanAges 8 years+ - NCT07645066Recruiting
Heart Pacemaker Placement to Prevent Irregular Heartbeat
This trial tests a new pacemaker placement technique for people with a slow heartbeat (sinus node dysfunction) who need a pacemaker anyway. The goal is to see if this special placement can help prevent atrial fibrillation, a type of irregular heartbeat that can cause stroke and other complications.

This study registers people who are referred to cardiology or genetics for heart-failure–type symptoms or heart/cardiogenetic screening. It helps doctors understand how monitoring platforms may support diagnosis and follow-up.
Maastricht, LimburgAges 16 years+ - NCT07614659Recruiting
Heart health screening for adults in Uppsala, Sweden
This study invites residents of Uppsala, Sweden who are turning 50, 55, 60, 65, 70, or 75 to participate in cardiovascular (heart and blood vessel) health screening. The goal is to help identify heart health risks early so you can take steps to stay healthy.
UppsalaAges 50–75 - 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+ - 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 - NCT07595068Recruiting
Ultrasound for Sleep and Heart Function Before Heart Surgery
This trial tests a new treatment using focused ultrasound to help regulate your nervous system and improve sleep quality before heart surgery. The goal is to help reduce anxiety and improve how well you sleep during the time leading up to and after your cardiology procedure.
Huangshi, HubeiAges 18–79 - NCT07583784Recruiting
Shorter blood thinner treatment after heart attack with irregular heartbeat
This trial tests whether patients with both irregular heartbeat (atrial fibrillation) and a recent heart attack can safely take a shorter course of blood-thinning medications after a stent procedure. The goal is to reduce bleeding risk while still protecting against future clots.
Gwangju, GwangjuAges 19 years+ - NCT06199180Recruiting
Comparing two ablation methods for repeat atrial fibrillation treatment
This trial tests a newer type of energy (pulsed field ablation) against the standard heat-based method (radiofrequency) for people who have already had one ablation and now have atrial fibrillation again. The goal is to see which works better for keeping your heart in a normal rhythm.
GroningenAges 18–80 - 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.
LondonAges 18 years+ - 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 - NCT07518446Recruiting

Remote Heart Monitoring After Aortic Valve Replacement
This study tests whether monitoring your heart rhythm at home using a portable ECG device after your aortic valve replacement procedure (TAVI) helps catch problems early. Researchers want to see if remote monitoring is safe and helpful for patients recovering from this procedure.
TurinAges 18 years+ - NCT07515040Recruiting
AccuSafe guidewire versus needle for heart rhythm procedure
This trial compares two different tools used during a minimally invasive heart procedure to treat atrial fibrillation (an irregular heartbeat). The study tests whether a newer guidewire tool is safer and works as well as the traditional needle approach.

Village doctor telehealth program for heart failure with atrial fibrillation
This trial tests a program where village doctors use telehealth to support patients who have both atrial fibrillation (an irregular heartbeat) and heart failure (when the heart doesn't pump well). It aims to improve their health and quality of life.

Common questions
- Are there clinical trials for atrial fibrillation?
- Yes. Clin2 currently lists 543 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.
