Atrial fibrillation (AF) is an important arrhythmia in hypertrophic cardiomyopathy (HCM). ⋯ AF is highly prevalent in patients with HCM. The presence of AF is associated with major adverse clinical outcomes. These findings suggest that both, aggressive screening and treatment of AF, are likely to have major prognostic impact on outcomes in HCM. Incidence, prevalence and prognostic impact of AF in HCM. In this systematic review, AF incidence was 2.5 cases per-person years, prevalence was 22.3%. AF in HCM was associated with a seven-fold increased risk of thromboembolism, 2.8-fold increased risk of heart failure, 1.7-fold increased risk of sudden death and 2.5-fold increased risk of all-cause mortality.
