[Observations on the peripheral vascular network of the myocardium during infarction].

The patterns of microvascular network have been examined in myocardium of 61 patients which died of subendocardial or transmural myocardial infarctions. The microangiographic patterns of interventricular septum and ventricular wall with or without morphological lesions have been compared. The investigations are related to the differences in microvascularization of various morphological types of myocardial infarctions. Our study confirms the classification of myocardial infarcts into microfocal and massive types. It explains the milder clinical course of microfocal subendocardial infarctions.
