[Cardiac insufficiency and its morphological expression].
The paper sets forth materials reflecting the present-day views of morphologists concerning the problem of cardiac insufficiency. The current state of the problem relating to morphology of the myocardium in cardiac incompetence is characterized. It is suggested that cardiac incompetence cannot be approached as a unique issue, and in different affections the pathogenesis of the heart muscle debility may prove to be dissimilar. Ultrastructural changes in the left heart myocardium of the rabbit, at a distance from the ischemic area, in experimental myocardial infarction at the stage of compensatory hypertrophy and with developing acute cardiac incompetence are described. In the lastly named case the mitochondria of myocites were found to contain compact bodies, apparently made up of calcium phosphate. Their appearance comes as a proof of irreversibility of the supervened changes.
