30,000 seniors to wear heart patches in massive Stroke-Prevention study
NCT ID NCT07627672
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will test whether a small, wearable patch that records heart activity for 7 days can find undiagnosed atrial fibrillation (a common heart rhythm problem) in 30,000 Chinese adults aged 60 and older. Participants will wear the patch and then be followed for up to 10 years to see if early detection helps prevent strokes, heart failure, or death. The goal is to improve screening for this condition in community settings.
