Summary

This large study tests whether a smartphone app can help prevent strokes by detecting atrial fibrillation (an irregular heartbeat) early. Adults aged 65 and older in Austria are randomly assigned to use the 'Pulskontrolle' app for pulse checks or to receive usual care. If the app finds a possible problem, a 7-day ECG patch confirms the diagnosis, and participants get digital support. The main goal is to see if this approach reduces hospitalizations for stroke over 48 months.

What this could mean

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

Active substance
Smartphone-based atrial fibrillation screening app (Pulskontrolle) with confirmatory ECG patch
What this could lead to
If effective, this approach could prevent thousands of strokes by catching hidden atrial fibrillation early using just a smartphone.
What could go wrong
The screening may miss some cases or cause false alarms, and it's unclear if digital management will reduce strokes more than usual care in a real-world setting.
