Can blood tests predict stroke risk in silent atrial fibrillation?
NCT ID NCT07713615
First seen Jul 20, 2026 · Last updated Jul 21, 2026 · Updated 1 time
Summary
This observational study investigates whether blood clotting markers and heart ultrasound measurements can help assess stroke risk in people with device-detected atrial fibrillation—a brief, symptomless irregular heart rhythm picked up by pacemakers or similar implants. Researchers will compare 111 participants with this condition to 111 matched controls without it, following them for up to 10 years. The goal is to better understand who might benefit from blood-thinning medication, which reduces stroke risk but increases bleeding risk.
What this could mean
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 research could lead to better ways to identify which patients with device-detected atrial fibrillation are at highest risk of stroke and would benefit most from blood-thinning medication.
- What could go wrong
- This is an observational study, not a treatment trial, so it cannot directly prove that any new approach reduces strokes. The findings may not change current practice without further validation.
