    Overall, myocardial diseases can be subdivided into two types: primary and secondary myocardial diseases. Whereas the primary type most commonly has a genetic cause, secondary myocardial diseases are mostly acquired but may be precipitated by a genetic background. Overall, the dilated type is the most prevalent manifestation of cardiomyopathy, and may be induced by a multitude of precipitating factors, such as chronic ischemia or alcohol abuse. The most common primary myocardial disease is hypertrophic cardiomyopathy, which is associated with a wide variety of genetic abnormalities. In the light of their substantially larger prevalence, we will first describe the secondary myocardial diseases, after which the less frequently occurring primary myocardial diseases will be discussed.

    • 7.1: Myocardial Disease - Secondary
      Myocardial disease subsequent to a known origin is termed secondary myocardial disease. Timely correction of the originating disease may result in reversal of the cardiomyopathy.
    • 7.2: Myocardial Disease - Primary
      Five different groups of primary myocardial disease exist; which are defined as diseases of the myocardium with impaired cardiac function, also referred to as cardiomyopathies. (1) Hypertrophic cardiomyopathy (HCM), (2) Dilated cardiomyopathy (DCM), (3) Restrictive cardiomyopathy (RCM), (4) Arrythmic cardiomyopathy (ACM) ,and (5) Unclassified cardiomyopathy (UCM)
