Watch for hidden atrial fibrillation after unexplained stroke
Part of Brain & nervous system, Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are age 55 or older
- Your stroke was called “cryptogenic” (no clear cause) after brain imaging, blood-vessel checks, a 24-hour heart monitor, and an echocardiogram
- Your stroke affected the brain’s outer layer (an “acute cortical infarction”) and there is an artery blockage inside the brain (intracranial occlusion)
- Your disability score is less than 4 on the Modified Rankin Scale (you can likely manage daily activities with limited assistance)
- You must not have had a “lacunar” stroke or a transient ischemic attack (TIA) instead of this type of stroke
- You must not already have a known stroke source like atrial fibrillation, other major heart causes, or certain vessel narrowing causes, and you should not have a pacemaker

This trial uses a small heart monitor to see if certain heart changes can predict hidden atrial fibrillation in people who had a stroke or mini-stroke with no clear cause. It aims to find those who might benefit from blood thinners to prevent another 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.
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.
This study uses AI-powered heart monitoring to detect a type of irregular heartbeat (atrial fibrillation) that may develop after a stroke. Catching this condition early could help prevent future strokes and guide your treatment.
This study tests whether using a smartphone app to check your heart rhythm after a stroke can find hidden atrial fibrillation (an irregular heartbeat). If you had a recent stroke or TIA and are not already on blood thinners, you may be able to help doctors detect and prevent future strokes.
This study tests whether using a smart watch to track your heart rhythm and guide treatment decisions can help manage paroxysmal atrial fibrillation (an irregular heartbeat that comes and goes). Researchers will monitor your heart activity continuously through wearable devices to see if this approach improves outcomes.
