Pathology of cardiomyopathy. An autopsy analysis of twenty-five cases

Pathology of twenty-five autopsied causes of cardiomyopathy is presented. Twenty cases were those of congestive cardiomyopathy. The ages varied between eleven and sixty-eight years and there were nine females and eleven males. The heart weights ranged between 240 gm and 600gm. Thrombi in the heart were encountered in 60% cases. Five cases conformed to endomyocardial fibrosis. The age ranged between twelve and forty years and all were males. Three cases out of five had severe left inflow tract involvement. Only one case showed predominant right sided involvement. No cases of hypertrophic cardiomyopathy were encountered. There appears to be a higher incidence of EMF in the Southern parts of India as compared to the other regions where COCM is most commonly encountered. The variation in the type of cardiomyopathy encountered in different parts of India, may well be related to dietary, climatic conditions or infections, peculiar to that area.
