What is hypertrophic cardiomyopathy (hcm)?

HCM. Hypertrophic cardiomyopathy is a rare condition of the actual muscle of the heart becoming so large and thick as to obstruct outgoing blood flow. Because outgoing flow is reduced the heart must work even harder to pump blood to supply oxygen to the body. It is notable because patients are usually asymptomatic but can initially present with sudden collapse or even death.
HOCM. Hocm is a condition of local muscular obstruction to the outflow of blood from the heart. It is part of the spectrum of hypertrophic cardiomyopathy which is abnormally thick heart muscle usually genetically related.
