This study uses a small implantable heart monitor to track heart rhythm in people after an acute ischemic stroke or TIA. It aims to learn how often hidden heart rhythm problems show up, which could help doctors choose better stroke prevention treatments.
AthensAges 40–100 - NCT05565781Recruiting
Watch for hidden atrial fibrillation after unexplained stroke
This study uses a smartwatch and a longer heart-monitoring test (a Holter) to find an irregular heart rhythm called atrial fibrillation after a stroke whose cause is unclear. If they detect it, it may help guide better prevention and treatment to reduce future stroke risk.
Barcelona, CataloniaAges 55 years+ - NCT05598632Recruiting
People with atrial fibrillation registry to study stroke risk
This registry study follows people with atrial fibrillation to learn which risk factors are linked to stroke or blood clots traveling through the body. Your information helps improve how doctors predict risk and choose prevention strategies.
Beijing, Beijing MunicipalityAges 18–120 - 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+ - NCT05790707Recruiting
Ablation for persistent atrial fibrillation to help memory
This study checks whether a procedure called atrial fibrillation ablation can slow memory problems in people who already have mild cognitive impairment. Participants will be tested on thinking and memory before and after treatment to see if the procedure helps.
AngersAges 60–80 - NCT05794386Recruiting
Ablation plan guided by left-heart scar map for persistent atrial fibrillation
This study tests whether using a 3D heart “scar map” helps doctors choose a better catheter ablation strategy for people with persistent atrial fibrillation (AF). It may help reduce ongoing AF by targeting the scar area in the left atrium.
Seoul, Jongno-guAges 19 years+ - NCT05795842Recruiting
Detecting atrial fibrillation after stroke using a wrist monitor
This study checks whether a special wrist device can detect an irregular heartbeat (atrial fibrillation) in people who recently had a stroke with an unclear cause. It may help doctors find the cause earlier and tailor follow-up care.
Atlanta, GeorgiaAges 55 years+ - NCT05836987RecruitingPhase 3
Smartwatch monitoring trial to guide blood thinner use for AF
This study tests whether continuous heart-rhythm monitoring with a smartwatch can better guide treatment for atrial fibrillation (AF) while you stay on a blood thinner. The goal is to improve safety and reduce stroke risk by catching AF patterns more closely.
Phoenix, ArizonaAges 22–85 - NCT05900414Recruiting
Help choosing blood thinners to prevent stroke in AF
This trial tests a web-based decision aid that helps people with atrial fibrillation (AF) decide about stroke-prevention treatment, such as blood thinners. It may help you feel more confident and make safer choices by showing options at the right time after diagnosis.
Calgary, AlbertaAges 18 years+ - NCT05951101Recruiting
Device to close an irregular heartbeat heart pocket safely
This trial tests the Zenith system, a device that seals off a heart area called the left atrial appendage to reduce stroke risk in people with atrial fibrillation (AF). You may be eligible if you have AF and a doctor recommends LAA closure, and you can return for follow-up scans and visits.
Parkville, VictoriaAges 18 years+ - 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+ - NCT05963698Recruiting
Closing off a heart pouch to prevent stroke
This study tests a procedure that seals off the left atrial appendage (a small heart pouch) to help prevent stroke in people with atrial fibrillation. You may be considered if your stroke risk is high and you are already on blood-thinner medicine.
Birmingham, AlabamaAges 18 years+ - NCT06005233Recruiting
Smartwatch heart monitoring after unexplained stroke
This trial uses a smartwatch to look for hidden atrial fibrillation (an irregular heart rhythm) in people who have had a stroke or TIA with no known cause. It could help find the reason for the stroke and guide treatment to prevent another one.
MunichAges 40 years+ - NCT06021808Recruiting
LAA clip vs. blood thinners to prevent stroke in non-paroxysmal AF
This study compares two ways to prevent stroke in people with persistent or long-standing atrial fibrillation (AF): taking a blood thinner (NOAC) or having a minimally invasive procedure to clip off the left atrial appendage (LAA). The goal is to see which approach works better at preventing stroke without causing major bleeding.
Beijing, Beijing MunicipalityAges 18 years+ - NCT06047782Recruiting
MRI study of atrial scarring and stroke risk
This study uses a special heart MRI to look for scarring in the upper chambers of the heart (atria) that might cause hidden atrial fibrillation after a stroke with no known cause. It may help explain why the stroke happened and guide future treatment.
DijonAges 18 years+ - NCT06061757Recruiting
Combining 4D-ICE and TEE imaging for heart closure
This trial tests a new imaging method (4D-ICE) used alongside a standard ultrasound (TEE) during a heart procedure to close the left atrial appendage, a small pouch in the heart where clots can form in people with atrial fibrillation. The goal is to see if the new method makes the procedure safer and more precise.
Overland Park, KansasAges 18–80 - NCT06075628Recruiting
CT scan study after LAA closure procedure
This study looks at long-term outcomes after LAA closure (a procedure to reduce stroke risk) by reviewing CT scans of the device. It aims to learn if blood flow around the device affects healing and future health.
Overland Park, KansasAges 18 years+ - NCT06108414RecruitingPhase 4
Low-dose vs standard-dose blood thinner for older adults with atrial fibrillation
