Key result
HCM is linked to a ~24-fold higher risk of ventricular arrhythmia and sudden cardiac death.

HCM markedly raises ventricular arrhythmia risk observationally; leaves open whether intensified monitoring or prevention alters outcomes.

Does hypertrophic cardiomyopathy increase the risk of cardiovascular events and bleeding compared to the general population?
Effect estimate: IRR 23.53 (95% CI 12.67-43.72)
Hypertrophic cardiomyopathy is associated with a profoundly increased risk of ventricular arrhythmias, sudden cardiac death, heart failure, and atrial fibrillation compared to the general population, highlighting a major unmet clinical need.
Pujades‐Rodríguez et al. (2018) conducted a cohort in Hypertrophic cardiomyopathy (n=12,760). Hypertrophic cardiomyopathy vs. General population without hypertrophic cardiomyopathy was evaluated on Ventricular arrhythmia (IRR 23.53, 95% CI 12.67-43.72). Hypertrophic cardiomyopathy was associated with a markedly higher risk of ventricular arrhythmia (IRR 23.53; 95% CI 12.67-43.72) and sudden cardiac death compared to general population controls.
