How Common is Hypertrophic Cardiomyopathy?

Hypertrophic Cardiomyopathy is a not an uncommon heart disease. Recent publications indicate that HCM is the most common of all genetic heart conditions affecting 1 in 500 people in the general population.  Based on these data we may estimate that as many as 600,000 people in the United States have HCM.  Subsequent studies have also proven that HCM has a prevelance of 1 in 500 in a wide variety of populations including, Native Americans, Chinese, Rural Midwestern US, and others. There is no gender, age or ethnic factor specific to HCM, HCM is an equal oppertunity disease.

In comparison Cystic Fibrosis has a prevalence of 1 in 3300. This means HCM is nearly 7 times more common than Cystic Fibrosis.
