Hypertrophic cardiomyopathy facts

A disease that causes the heart muscle to become abnormally thick, making it harder for the heart to pump blood.

It may affect the heart's electrical system.

It often is undiagnosed due to few, if any, symptoms.

For a small number of sufferers, though, symptoms can include shortness of breath and problems in the heart's electrical system, resulting in life-threatening, abnormal heart rhythms.

Those with hypertrophic cardiomyopathy can often lead normal lives with no significant problems.
