Abstract

This paper studies the characteristics of the myocardial bridges and the anterior interventricular artery in people aged 22–75 years using a histological method. Histological sections were made from three segments of the artery: proximal to the bridge, intramural and distal to the bridge. We found no differences in thickness of myocardial bridges, cross-sectional area of the perivascular space, as well as ratio of the cross-sectional areas of the perivascular space and intramural segment between the groups of hearts with coronary atherosclerosis (n = 7) and without it (n = 7). In subjects with coronary atherosclerosis, the cross-sectional area of the artery wall in the segment proximal to the bridge was larger than that in the group without atherosclerosis due to increased intima thickness. However, no changes in the lumen of the artery were observed.
