Introduction[edit | edit source]

Cardiomyopathy is defined as a "disease of the myocardium with associated cardiac dysfunction".[1]

  • The nonischemic cardiomyopathies are a diverse group of cardiac disorders that frequently cause heart failure and death and are now recognized with increasing frequency.
  • There has been substantial progress in the clinical recognition and understanding of the natural history of these conditions. Well-established and new techniques of cardiac imaging are helping in this regard. [2]
  • Nearly, 50% of patients dying suddenly in childhood or adolescence or undergoing cardiac transplantation are affected by cardiomyopathies.[3]

Classification[edit | edit source]

Cardiomyopathy classification separates the various cardiomyopathies into several subtypes.

It was initially classified according to the 1995 World Health Organisation / International Society and Federation of Cardiology (WHO/ISFC) system as follows:

  1. dilated cardiomyopathy
  2. hypertrophic cardiomyopathy
  3. restrictive cardiomyopathy  
  4. arrhythmogenic right ventricular cardiomyopathy[1]
