[Chronic cor pulmonale--a disease of the right or both ventricle(s) of the heart?]

Abstract

Some aspects of the development of chronic cor pulmonale have been presented. Special attention has been paid to the possibility of simultaneous formation of changes in the muscle of both ventricles of the heart and to an increase in the number of capillaries in the myocardium in the early stage of this disease. Angiogenesis, the role of hypoxia and endothelins in the pathogenesis of these changes have been discussed.
