AbstractThe most recent WHO/ISFC classification of cardiomyopathies (1995) describes as cardiomyopathies all heart muscle diseases, which demonstrate a disturbance of cardiac function. It distinguishes primarily according to hemodynamic criteria the following 5 forms: 1. dilated (DCM), 2. hypertrophic (HCM), 3. restrictive (RCM) from 4. arrhythmogenic right ventricular (ARVCM) and assembles in 5. non-classified cardiomyopathies (NKCM) the non-classifiable forms. When compared to the 18-year-old former classification several points have been altered: 1. ARVCM has been introduced as a new entity. 2. The new term ischemic cardiomyopathy has been reserved for the remodeling process of the non-infarcted myocardium and does not mean hemodynamic alterations of an infarcted area (aneurysm), of stunned or hibernating myocardium. Hypertensive cardiomyopathy corresponds to left ventricular hypertrophy in hypertensive patients, valvular cardiomyopathy identifies cardiomegaly, which cannot sufficiently be explained by the valvular dysfunction (stenoses or insufficiency) alone. For the first time the term inflammatory cardiomyopathy has been used and defined as acute or chronic myocarditis associated with cardiac dysfunction, for which etiological and pathogenetic factors, e.g. viral or microbial infection or autoimmune processes have been made responsible. Two ISFC task forces have just recently clarified in consensus conferences the immunohistopathological criteria for chronic myocarditis or dilated cardiomyopathy with inflammation (DCMi: > 14 lymphocytes or macrophages/mm3) and set standards for molecular and virological diagnoses in endomyocardial biopsies.
