Cardiomyopathy Q & A

What is Cardiomyopathy?

A cardiac condition that leads thickening and enlargement of the heart muscle. In rare and untreated cases, the heart muscle can be replaced with scar tissue. The main types of cardiomyopathy include dilated, hypertrophic, and restrictive.  Causes of dilated cardiomyopathy include hypertension, HIV, viral infection, diabetes, and sometimes no identifiable cause is known. 

Hypertrophic cardiomyopathy is an inherited form that can lead to sudden cardiac death in athletes.  Restrictive cardiomyopathy can be caused by buildup of iron (hemochromatosis), inflammation of organs (sarcoidosis), abnormal protein buildup (amyloidoisis).  As the cardiomyopathy worsens, the heart muscle can weaken and lead to dilation, arrhythmias, and pump failure.
