Eighty cases of primary cardiomyopathy were classified clinically into 4 categories. Fifteen of them were autopsied and their pathological classification was shown. Among these 80, clinical pictures of 15 obstructive and 51 non-obstructive cases were outlined. The clinical picture of these 66 cases was, in general, similar to that reported from western countries.
Although specific infectious diseases were omitted from the group, myocardial inflammation was suggested as a possible cause of the myocardial disease in 7 non-obstructive cases.
History as a chronic alcoholic, which has long been neglected in Japan as a cause of cardiomyopathy, was revealed in 6 cases of non-obstructive cardiomyopathy. Their clinical findings suggested a gradually progressing disease of the myocardium, which involved diffusely all cardiac chambers. Predominant right heart involvement was not observed.
The gray area between obstructive and non-obstructive cardiomyopathy was discussed and possible inclusion of the former cases in the latter group was suggested.
