Some big hearts are thick and stiff because of Hypertrophic Cardiomyopathy

Hypertrophic cardiomyopathy (HCM) is a common genetic disorder that affects people regardless of gender, ethnicity, age or geographic location. HCM is known by many names and it is important to understand that it is, for the most part, one disease.

Frequently, those with hypertrophic obstructive cardiomyopathy (HOCM, oHCM), apical hypertrophic cardiomyopathy, or asymmetric septal hypertrophic cardiomyopathy think these are completely different diseases. They are actually different physical presentations of hypertrophic cardiomyopathy. In other words, "obstructive," "apical," or "asymmetric septal" are descriptions of the current state of the disease.


This website explores various aspects of hypertrophic cardiomyopathy:

  • Clinical
  • Emotional
  • Social
  • Policy


We provide critical information and assistance to our Bighearted Community through clinically reviewed information, support options, and member services.
