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. Oftentimes, those with hypertrophic obstructive cardiomyopathy(HOCM, oHCM), apical hypertrophic cardiomyopathy, or asymmetric septal hypertrophic cardiomyopathy think this is a completely different disease. When in reality it is all hypertrophic cardiomyopathy with varied physical presentations. Put differently, the words "obstructive," "apical," or "asymmetric septal" are just descriptions of the current state of the disease.

This website will expand your knowledge of hypertrophic cardiomyopathy as well as issues important to our community by providing clinically reviewed information, support options and member services.

The HCMA is the preeminent organization improving the lives of those with hypertrophic cardiomyopathy, HCM, preventing untimely deaths and advancing global understanding. Founded in 1996 we are committed to providing support, education, advocacy and advancing research, understanding and care to those with HCM.

Should you have questions at any point while reviewing this website, please reach out the the HCMA office at: 973-983-7429 or email us at support@4hcm.org and we will respond as soon as possible.
