The incidence of bridges of myocardium seen on the external surface of the heart, through the epicardium, over portions of coronary arteries and their branches, was studied in 50 cadavers and found to be 78%. The bridges of the myocardium varied in size and in number (from one to six). Their location was predominantly found at the level of the anterior ventricular branch of the left coronary artery also called left anterior descending artery (52%), whereas in the territory of the right coronary artery the highest percentage was at the level of the anterior ventricular branch (12%). This myocardio-arterial relationship might be responsible for periodic or permanent reduction of the lumen, partial or total arterial obliteration, ischemia, atherosclerosis, angina, and sudden death.
通过心外膜，在心脏外表面观察冠状动脉及其分支部分上心肌桥的发生率，在50具尸体中进行了研究，发现发生率为78%。心肌桥的大小和数量各不相同（从一个到六个）。它们主要位于左冠状动脉前室支（也称为左前降支）水平（52%），而在右冠状动脉区域，最高百分比位于前室支水平（12%）。这种心肌与动脉的关系可能是管腔周期性或永久性缩小、部分或完全动脉闭塞、缺血、动脉粥样硬化、心绞痛和猝死的原因。
