Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle (myocardium) becomes abnormally thick (hypertrophied). The thickened heart muscle can make it harder for the heart to pump blood. HCM is the most common genetic cardiovascular disease. It is estimated to affect 1 in 500 people. http://visualvistaventures.weebly.com/digital-endowments/hypertrophic-cardiomyopathy-hcm-therapeuticsemerging-therapies-for-a-challenging-disease
