10,000 AF patients tracked to find stroke threshold
NCT ID NCT07497906
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This observational study will follow 10,000 people with atrial fibrillation for 24 months. Researchers will use smartwatch data to measure how much time the heart is in AF (AF burden) and see if that predicts strokes or blood clots. The goal is to find a clear threshold where blood thinners become beneficial. No new treatments are being tested; it is purely data collection.

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help doctors better decide when to use blood thinners in atrial fibrillation patients, potentially preventing strokes.
What could go wrong
This is an observational study, not a treatment trial. It can only show links, not prove cause and effect. Results may not change practice directly.
