Cardiomyopathy Epidemiology and Demographics

Incidence and prevalence differ based on cause.

• The incidence of DCM has been estimated to be 5-8 cases per 100,000 population, with a prevalence of 36 per 100,000. This could be explained by the incomplete disease expression, which goes unrecognized.
• The prevalence of HCM in the absence of aortic valve disease or systemic hypertension is at least 200 per 100,000 of the adult population.
• RCM is much less common than either DCM or HCM in the developed world, but is a frequent cause of death in the tropical countries, primarily because of the high incidence of endomyocardial fibrosis in those regions.
