The detected electrocardiographic changes, hypoxia, disturbances of the hormone-mediator-enzymatic metabolism an increased affinity to the myocardial cell stain at the early periods of diabetes mellitus development permitted to regard cardiovascular affections in diabetes mellitus as a manifestation, not as a complication of the disease.
