Association of Autoimmune Vasculitis and Incident Atrial Fibrillation: A Population‐Based Case‐Control Study

Background Recent investigations suggest that inflammation and autoimmunity might have a role in the pathophysiology of atrial fibrillation (AF). Given that abnormal ventriculovascular coupling often coexists with AF, we hypothesize that autoimmune vasculitis plays a significant role in the pathogenetic mechanism of AF. Methods and Results A standardized retrospective population‐based case–control study was conducted to evaluate the association...
