[Presence of the muscular bridges and their influence on coronary insufficiency].
In this work we have analyzed 512 coronary angiograms that were done during 2003 year at the Clinic for heart diseases and rheumatism of the University of Sarajevo Clinic Center (UCCS) and we have dissected 20 human hearts at the Institute for Anatomy. We strived to prove frequency of the muscular bridges on branches of the coronary artery, their localization and influence on the arteriosclerotic changes. Using coronary angiography method we consluded that the presence of the muscular bridges in observed population in 4.88% of cases, with the most frequent localization on the anterior interventricular branch (ramus interventricularis anterior). By dissection method the muscular bridges have been found in 55% of cases and the most frequent localization was on the anterior interventricular branch and branches of the right coronary artery. Smaller frequency of the muscular bridges, shown by the angiography method, can be explained by the fact that thick muscular bridges perform weak compression and because of that minimal systolic reduction of the lumen which can not be noticed by the angiography. The muscular bridges are four times frequent on males and they are the most frequent in the age group from 40 to 50 years. In the 88% of patients with the muscular bridges were found arteriosclerotic changes localized proximately from muscular bridge.
