The objective of PIAAF SCREEN AF was to offer primary care patients, aged 75 years and older, new technologies to detect atrial fibrillation (AF) using a wearable ECG patch and a blood pressure machine that has the ability to detect AF.

The aim was to establish a practical and cost-effective screening strategy that could be easily applied in primary care for early detection and treatment of AF. The SCREEN-AF trial is a Canadian multicenter study of atrial fibrillation (AF) screening being conducted in a home-based setting.

Primary outcome:

The new diagnosis of ECG-confirmed atrial fibrillation or flutter within six months post-randomization.

Co-Principal Investigators, with Jeff Healey of PHRI, were:

  • Rolf Watcher, University of Goettingen
