Sudden cardiac death in hypertrophic cardiomyopathy: risk evaluation

Mortality due to hypertrophic cardiomyopathy is only around one percent per annum in unselected patients [1]. Therefore, the incidence of sudden cardiac death is still lower. However, identification of this small subgroup is important because prophylactic intervention may reduce mortality [2–5]. Unfortunately, we still do not have an accurate method of identifying this high risk subgroup.
