72 human hearts from necropsies of subjects with an age range from 27 to 83 years have been examined by dissection. The aim of this study was to know the percentage of myocardial bridges (intramural coronary arteries) and to compare with other studies carried on this subject, using the same or different techniques. Myocardial bridges were observed in 25% of cases. The main localization was the middle third of the anterior interventricular artery. The principal characteristics of the myocardial bridges were: The length, from 4 mm to 25 mm, and the thickness, from 0.3 mm to 1.7 mm. Chi-square test have been made in order to verify the relation between the coronary arterial preponderance and the incidence of myocardial bridges, showing the absence of statistical significance.
通过解剖检查了72颗取自年龄在27岁至83岁之间受试者尸检的心脏。本研究的目的是了解心肌桥（壁内冠状动脉）的百分比，并与使用相同或不同技术对该主题进行的其他研究进行比较。在25%的病例中观察到心肌桥。主要定位在前室间动脉的中三分之一处。心肌桥的主要特征为：长度从4毫米至25毫米，厚度从0.3毫米至1.7毫米。进行了卡方检验以验证冠状动脉优势与心肌桥发生率之间的关系，结果显示无统计学意义。
