The ultrastructure of the contractile myocardium taken from different zones of the left and right ventricles of the heart was studied during dosed restriction of blood flow in the circumflex branch of the left coronary artery by 30 and 50%. It was established that the changes of the cardiomyocytes in this situation are displayed by a combination of two differently directed processes, destructive-dystrophic and adaptational, the severity of which is determined by the intensity of the unfavourable effect. The whole parenchyma of the ventricles of the heart is involved in the reaction and there are no intact zones.
