Cardiomyopathies
Type of CMPFindings
Dilated (Congestive)All four chambers are dilated, and there is also hypertrophy. The most common cause is chronic alcoholism, though some may be the end-stage of remote viral myocarditis.
HypertrophicThe most common form, idiopathic hypertrophic subaortic stenosis (IHSS) results from asymmetric interventricular septal hypertrophy, resulting in left ventricular outflow obstruction.
RestrictiveThe myocardium is infiltrated with a material that results in impaired ventricular filling. The most common causes are amyloidosis and hemochromatosis.
