Miocardiopatías. Clasificación

Cardiomyopathies are a heterogeneous group of diseases associated with primary myocardial involvement. Unlike other heart conditions (pericardial diseases, hypertension, congenital heart disease, valvular or ischemic heart disease), cardiomyopathies are not the result of other diseases. The major morphological patterns are: dilated, hypertrophic, restrictive and arrhythmogenic right ventricular noncompaction. There are various classifications of cardiomyopathies. The most widely accepted are the World Health Organization (WHO) classification (1995), the American Heart Association (AHA) classifications (2006) and the European Society of Cardiology (ESC) classification (2007). AHA classification distinguishes between primary and secondary cardiomyopathies. ESC classification identifies the major morphological pattern types and thereafter distinguishes between familiar and unfamiliar cardiomyopathies.
