title: The prevention of sudden death in hypertrophic cardiomyopathy.
abstract: Hypertrophic cardiomyopathy (HCM) is a familial myocardial disease caused by mutations in cardiac sarcomeric proteins. HCM is characterised by myocyte disarray and myocardial fibrosis. Most patients are largely asymptomatic but some are prone to a number of disease-related complications, the most problematic of which is sudden cardiac death. Diagnosing patients who are at risk has not been easy because of the clinical heterogeneity of the disease, the frequent absence of symptoms prior to sudden cardiac death and the relatively low disease prevalence and annual mortality rates. To date, both low-dose amiodarone and internal cardioverter/defibrillator implantation have been advocated in high-risk individuals. Further improvements in clinical understanding and risk stratification are necessary to identify HCM patients who are at high risk of sudden death.
