Summary

This study is testing whether a wearable heart monitor (Zio patch) worn for two weeks can detect undiagnosed atrial fibrillation in women aged 70 and older. Atrial fibrillation is a common heart rhythm problem that raises stroke risk, especially in older women. The goal is to see how many women have this condition and whether screening leads to more use of stroke-preventing blood thinners.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: Zio patch wearable cardiac monitor
What this could lead to: If successful, this could show that widespread screening with a simple patch helps catch hidden atrial fibrillation in older women, potentially reducing their stroke risk.
What could go wrong: This is a small pilot study with only 120 participants, so results may not apply to all older women. The device may be uncomfortable or not worn correctly, and finding Afib does not guarantee that treatment will prevent strokes.
