Smartwatch heart monitoring after unexplained stroke
Part of Brain & nervous system, Heart & circulation clinical trials.
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.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You have a small heart monitor implanted (like an event recorder) that can send information to your doctor.
- You had a stroke or a TIA (mini-stroke) within the last 6 months that doctors couldn't find a clear cause for.
- You are 40 years old or older.
- You have at least one extra risk factor, such as a high stroke risk score (CHA2DS2VASc ≥4), short heart rhythm episodes, or enlarged heart chamber.
- You are willing and able to record your heart's activity using a smartwatch and have a compatible smartphone.
- You do not have a pacemaker or ICD, and you are not pregnant or breastfeeding.

This study tests whether a smartwatch can help people who have had a minor stroke or TIA (mini-stroke) prevent another one. The smartwatch tracks your daily activity and helps guide your recovery through movement goals.
This study checks whether a smartwatch can spot an irregular heartbeat called atrial fibrillation soon after on-pump heart surgery. If the smartwatch works well, it could help clinicians find the problem earlier after surgery.
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 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.
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.
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.
