[Diagnosis and pathogenesis of diabetic myocardiodystrophy]

On the basis of findings of a comprehensive investigation of 882 patients with diabetes mellitus making use of biochemical, electrophysiologic, radioisotopic and morphohistochemical methods, diagnostic criteria of diabetic myocardiodystrophy were identified, and a scheme of differential diagnosis between chronic coronary disease and myocardiodystrophy is proposed for diabetic patients. The correlation of morphological and histochemical changes in microcirculatory vessels of the myocardium and the skin has shown myocardial microangiopathy to be the morphologic substrate of diabetic myocardiodystrophy.
