Hybrid or catheter ablation for atrial fibrillation in hypertrophic heart
This trial compares two procedures to treat atrial fibrillation (an irregular heartbeat) in people who also have hypertrophic cardiomyopathy (thickened heart muscle). It looks at whether the hybrid approach or a catheter-based approach works better for controlling symptoms and heart rhythm.
BeijingAges 18 years+ - NCT06108414RecruitingPhase 4
Low-dose vs standard-dose blood thinner for older adults with atrial fibrillation
This trial tests whether a lower dose of the blood thinner rivaroxaban works as well as the standard dose for people 70 and older with atrial fibrillation (an irregular heartbeat). The goal is to find the safest dose to prevent strokes while reducing bleeding risks.
Beijing, Beijing MunicipalityAges 70 years+ - NCT05679024RecruitingPhase 3
Apixaban to prevent stroke in atrial fibrillation and kidney failure
This trial tests apixaban (a blood thinner) to prevent stroke in people with atrial fibrillation or atrial flutter who have very poor kidney function or are on dialysis. If you qualify, you may help researchers find a safer way to lower stroke risk for this higher-risk group.
HelsinkiAges 18 years+ - NCT06647251Recruiting
Comparing different radiofrequency modes for atrial fibrillation ablation
This trial tests three different ways of delivering radiofrequency energy using a specific catheter (QDOT) during a first-time procedure to treat atrial fibrillation (AF), a type of irregular heartbeat. It aims to find which method works best for patients with recent or short-lasting AF episodes.
Paris, ParisAges 18 years+ - NCT06675383Recruiting
Screening for atrial fibrillation after stroke
This trial tests whether extended monitoring can detect hidden atrial fibrillation (an irregular heartbeat) in people who have had a stroke. If found, treatment can help prevent another stroke.
