title: [Relation between morphometric criteria of the functional status of the arterial and microcirculatory bed of the myocardium in acute coronary insufficiency and the type of blood supply].
abstract: Criteria of myocardial microcirculatory bed functional state under 3 types of blood supply of the heart with non-stenotic and stenotic coronary sclerosis were studied by the stereomorphometric method on 51 autopsies. These were cases of sudden death of acute coronary failure (men from 41 to 70 years old). Different degrees of total and specific volume decrease was found to be in correlation with the decrease in the quantitative parameters of "cardiomyocyte-capillary system". The specific features of interrelationship between parenchyma and capillaries under different types of blood supply show the variants of microcirculatory compensatory potential and explain the reasons for more frequent deaths in the extreme types. There was a direct relationship between the progressive coronary artery atherosclerosis, structure of microarterial bed rearrangement, myocardial circulation and the type of blood supply.
