Hypertrophic cardiomyopathy

The normal heart has strong muscular walls that pump blood out of the heart.

Hypertrophic cardiomyopathy is a condition in which the walls of the heart; the muscular pumping chambers, become abnormally thick. There is likely a genetic cause.

In hypertrophic cardiomyopathy, the heart fails to pump adequately. In many patients, this condition may not cause symptoms until it is very severe. Individuals with this condition may be at higher risk for sudden cardiac arrest. Symptoms can include breathlessness, rhythm abnormalities, and fainting.
