Current perspectives in hypertrophic cardiomyopathy: diagnosis, clinical management, and prevention of disability and sudden cardiac death.

Hypertrophic cardiomyopathy is a rare primary myocardial disease known for its dramatic morphologic and clinical manifestations. Sudden cardiac death and functional cardiac symptoms are common. However, differing pathologic mechanisms may be responsible for similar clinical symptoms and make a unified approach to therapy impossible. This review will discuss the genetics, criteria for diagnosis, relationship among pathophysiologic abnormalities and clinical symptoms, and management of hypertrophic cardiomyopathy.
