[Ultrastructure of intermitochondrial contacts of human cardiomyocytes in alcoholic cardiomyopathy and ischemic heart disease].

Intermitochondrial contacts in human cardiomyocytes are revealed. In alcoholic cardiomyopathy they have the same morphological features as those previously described in the cardiomyocytes of vertebrates. The ultrastructure of these contacts in patients with circulation deficiency in ischemic heart disease is altered. This alteration of the ultrastructure may represent a direct reaction of the cardiomyocyte mitochondrial system to the change in the level of energetic metabolism.
