[Comparative stereometric study of the intramural arterial bed of the human myocardium using injection and non-injection methods].

Comparative sterometric study of intramural arterial bed of the left ventricle wall of 20 injected and 30 non-injected hearts of practically health adults aged from 24 to 27 years (after violent death) was conducted. The volumetric density index of intramural arterial bed(Vv) of the myocardium of the left ventricle wall was on the average 9 times less in case of non-injected hearts than in the injected ones. The Vv was the greastest in the middle type of the coronary circulation of the heart. The non-linear dependence between the Vv and the age was revealed. The Vv decreased with the increase of the heart weight. With the equal indices of the heart weight the Vv was significantly higher in females than in males. The non-injection sterometric method used for the study of the inorganic arterial bed simplifies and objectifies the estimation of the state of myocardial blood supply and can be used in anatomopathological practice.
