[Role of the intramural arterial bed of the human heart in the pathogenesis of coronary arteriosclerosis and myocardial infarct (a stereometric study)].

Pathological and stereometric studies of the intramural arterial bed of 42 normal hearts and 39 hearts with myocardiac infarction were carried out by injection and non-injection methods. The stereometrical analysis has shown a wide variability of volumetric density of the intramyocardial arterial bed normally due to individual features of heart angioarchitectonics. Myocardial infarction developed more frequently in subjects with a small specific volume of the intramural bed. The low volumentrical density of the intramyocardial arterial bed appears to be conducive to rapid progress of atherosclerotic coronary sclerosis. It is suggested that the low volumentrical density of the intramyocardial arterial bed be considered as one of the risk factors in the development of ischemic heart disease.
