First seen Jan 24, 2026 · Last updated Jun 23, 2026 · Updated 19 times
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 they then receive blood thinners to prevent strokes.

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 routine screening with a wearable monitor helps detect 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 as directed, and detecting Afib doesn't guarantee better outcomes.
