Genetic Risk-Based Atrial Fibrillation Screening (GeneAF Study)

AF is the most common sustained arrhythmia in adults and its prevalence increases with advancing age. In this study, we aim to determine whether the published genome-wide polygenic scores for atrial fibrillation (GPSAF) can facilitate AF screening by accurately discriminating between patients with low and high risk for AF. All included patients are participating in the MHI biobank, an ongoing funded institutional DNA bank and clinical registry approved by the research ethics board where included patients consent for future genetic research. The study will compare AF detection rate using a 3 months near continuous monitoring in individuals with a high GPSAF with matched individuals from the bottom GPSAF.
