• A condition in which the myocardium is hypertrophied without an obvious cause. The hypertrophy is generally asymmetric and may be associated with obstruction of the ventricular outflow tract.

• Hypertrophic cardiomyopathy (HCM) is defined by the presence of increased ventricular wall thickness or mass in the absence of loading conditions (hypertension, valve disease) sufficient to cause the observed abnormality.

• (cardiomyopathy, hypertrophic) A form of CARDIAC MUSCLE disease, characterized by left and/or right ventricular hypertrophy (HYPERTROPHY, LEFT VENTRICULAR; HYPERTROPHY, RIGHT VENTRICULAR), frequent asymmetrical involvement of the HEART SEPTUM, and normal or reduced left ventricular volume. Risk factors include HYPERTENSION; AORTIC STENOSIS; and gene MUTATION; (FAMILIAL HYPERTROPHIC CARDIOMYOPATHY).

• Hypertrophic cardiomyopathy is a congenital or acquired disorder characterized by marked ventricular hypertrophy with diastolic dysfunction but without increased afterload (eg, due to valvular aortic stenosis, coarctation of the aorta, systemic hypertension). Symptoms include dyspnea, chest pain, syncope, and sudden death. A systolic...

• Hypertrophic cardiomyopathy (HCM) (see the image below) is a genetic disorder that is typically inherited in an autosomal dominant fashion with variable penetrance and variable expressivity. The disease has complex symptomatology and potentially devastating consequences for patients and their families.

• Hypertrophic cardiomyopathy (HCM) is a disease in which the heart muscle becomes abnormally thick (hypertrophied). The thickened heart muscle can make it harder for the heart to pump blood.

• Hypertrophic cardiomyopathy (HCM) is a genetic disorder characterized by left ventricular hypertrophy (LVH) without an identifiable cause. It is the most common genetic heart disease, as well as the most frequent cause of sudden cardiac death in young people. Given its prevalence in younger patients, HCM is frequently confused with...
