Could a simple 14-day heart monitor patch prevent strokes in at-risk seniors?

First seen Jun 30, 2026 · Last updated Jul 01, 2026 · Updated 1 time
Summary
This study investigates whether screening older veterans (age 65 and older) who have a higher risk of atrial fibrillation—a condition where the heart beats irregularly—can reduce their chances of stroke, heart failure, or death. Participants selected for screening wear a small, waterproof patch (Zio XT) that records their heart rhythm for up to 14 days. The results are shared with their doctors, who may then prescribe blood thinners if atrial fibrillation is detected. The study compares outcomes between those screened and those receiving usual care to see if early detection makes a difference.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Zio XT Patch (wearable heart monitor)
- What this could lead to
- If successful, this could show that widespread screening for hidden atrial fibrillation in older adults reduces strokes and saves lives.
- What could go wrong
- Screening may detect harmless irregularities, leading to unnecessary treatment and bleeding risks. The trial is large but observational in design, so results may not prove cause and effect.
