Hypertrophic Cardiomyopathy

Inside views of normal heart and of heart with thicker walls from hypertrophic cardiomyopathy

In hypertrophic cardiomyopathy, the heart muscle is thicker than normal. This may cause problems for some people. The heart may not pump blood as well as it normally does. The heart chambers might be smaller than normal. Or the heart muscle may not relax between beats as it normally does.
