Prevalence of atrial fibrillation dependent on coronary artery status: Insights from the LIFE‐Heart Study

Background Coronary artery disease (CAD) is a significant risk factor for atrial fibrillation (AF). Experimental studies demonstrated that atrial ischemia induced by right coronary artery (RCA) stenosis promote AF triggers and development of electro‐anatomical substrate for AF. Aim To analyze the association between AF prevalence and coronary arteries status in the LIFE‐Heart Study. Methods This analysis included patients with available coronary catheterization data recruited between 2006 and 2014. Patients with acute myocardial infarction were excluded. CAD was defined as stenosis ≥75%, while coronary artery sclerosis (CAS) was defined as non‐critical plaque(s)
