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+ - NCT05723926Recruiting
Carotid implants to help prevent stroke repeat in atrial fibrillation
This trial tests whether placing a carotid implant can reduce the chance of having another stroke in people with atrial fibrillation who are already taking blood thinners. It aims to prevent stroke recurrence while you continue prescribed anticoagulation.
Rockford, IllinoisAges 18 years+ - NCT07749183Recruiting
Light-based detection of atrial fibrillation in heart failure
This study tests a new device that uses light to detect irregular heartbeats (atrial fibrillation) in people with heart failure. If you join, you'll wear a small sensor that may help catch early signs of this condition.
BratislavaAges 18 years+ - NCT06516822Recruiting
Comparing two ablation methods for long-standing atrial fibrillation
This study tests whether adding extra scar lines (linear ablation) to the standard pulmonary vein isolation (CPVI) is better than CPVI alone for people with long-standing persistent AF that has lasted 1 to 3 years. The goal is to see which approach reduces AF better.
Beijing, Beijing MunicipalityAges 18–75 - 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+ - NCT06728826Recruiting
Preventing atrial fibrillation after heart surgery with pericardiotomy
This study tests if opening the sac around the heart (pericardiotomy) can lower the chance of developing an irregular heartbeat called atrial fibrillation after heart surgery. It is for people having surgery on the heart's valves, major blood vessels, or arteries.
ShanghaiAges 18 years+ - NCT04529785Recruiting
Tested added ethanol vein treatment during repeat atrial fibrillation ablation
This trial compares two ways to help stop atrial fibrillation during a repeat procedure: standard vein isolation only versus standard isolation plus an added medicine (ethanol) into the vein of Marshall. It aims to see whether the added step improves results when atrial fibrillation returns after a previous successful treatment.
