Wearable Heart Monitors Improve AFib Detection but Don't Lower Stroke Rates

Study shows a 52% increase in atrial fibrillation diagnosis, but no significant reduction in stroke hospitalizations due to early termination.

Duke Clinical Research Institute led the study involving around 12,000 participants aged 70 and older.
Participants using wearable monitors had a 52% higher detection rate of atrial fibrillation compared to usual care.
The study was halted early due to the COVID-19 pandemic, limiting its ability to confirm stroke reduction.
No significant difference in stroke-related hospitalizations or bleeding complications was observed.
Future research is needed to establish the link between AFib detection, treatment, and stroke prevention.
