Micra AV2 study: tracking heart rhythm and AFib
This study looks at how well the Micra AV2 pacemaker tracks your heart’s natural rhythm and detects brief episodes of atrial fibrillation (a fast, irregular heartbeat). It is for people who already have or will get this pacemaker and have had AFib that comes and goes.
New Hyde Park, New YorkAges 18 years+ - NCT04796714RecruitingPhase 4
Aspirin and clopidogrel after left heart appendix closure
This trial studies a “double anti-platelet” medicine plan (aspirin plus clopidogrel) after closing the left atrial appendage, a procedure used to reduce stroke risk in some heart rhythm conditions. It aims to find a safer, better medicine strategy for people who cannot take standard blood thinners.
PessacAges 18 years+ - NCT05204212Recruiting
Heart procedure to close an atrial clot risk pouch in kidney failure
This trial tests a heart procedure that closes a part of the heart called the left atrial appendage to help prevent stroke in people with an irregular heartbeat (atrial fibrillation) and very advanced kidney disease. It’s mainly for patients who can take the needed blood-thinner medicines and who do not already have a clot in that pouch.
Lübeck, Schleswig-HolsteinAges 18 years+ - NCT07109141Recruiting
Registry of Heart Rhythm Fix Procedures Using Pulsed Field Ablation in Poland
This study tracks people who have a procedure called pulsed field ablation to fix an abnormal heart rhythm (atrial arrhythmia). It's a registry, meaning researchers will collect information to learn more about how well the treatment works and how safe it is.
Wroclaw, Lower Silesian VoivodeshipAges 18 years+ - NCT07237308RecruitingPhase 4
Two blood thinners compared for stroke with atrial fibrillation
This study tests whether a common blood thinner (apixaban) alone is as safe and effective as combining it with another drug (clopidogrel) to prevent future strokes in people who have both atrial fibrillation and narrowing in the arteries leading to the brain. It aims to find the best way to reduce stroke risk while minimizing bleeding.
SeoulAges 19 years+ - NCT03357926Recruiting
Building predictions for atrial fibrillation in pacemaker patients
This study creates a database to better predict who with a pacemaker or ICD will develop atrial fibrillation (an irregular heart rhythm). It may help your care team spot risk earlier and tailor monitoring sooner.
