title: [The effect of myocardial bridging on the incidence of coronary arteriosclerosis].
abstract: In this paper we dissected 50 human hearts obtained from the Department for Anatomy and Department of Forensic Medicine and Pathology, Faculty of Medicne, Sarajevo. Our interest was to show frequency of myocardial bridging on human heart coronary artery branches, their localisation and dimensions. Cross sections of coronary arteries segments in area of bridges, proximal and distal to it, were taken out from hearts on which dissection method showed presence of myocardial bridging of the coronary artery branches. Cuts were made 5microm-tick and coloured by Hematoxylin-eosine, Elastica Van Giesson, and Ladewig after having been fitted into paraffin wax. Preparations were behold mocroscopically and flow direction of myocardial bridge muscle fibres was followed regarding the artery wall, and it was analysed artery wall structure in the myocardial bridge area, proximal and distal to the bridge. Myocardial bridges werw found in 42% examined cases, and with the most frequent localisation on ramus interventricularis anterior (34%). Atherosclerotic change in the artery segments proximal to the myocardial bridge was detected by the histolopathological method and its intensity depended on the myocardial bridge length and years of age. In the area of the myocardial bridge, besided insignificant diffuse intima, there were not any other histopathological changes that would indicate an atherosclerotic process.
