Pathognomonic incidence of myocardial bridges during obstructive hypertrophic cardiomyopathy, hypertension, and ischemic heart disease was established. Myocardial bridges were predominantly found in the median segments of major coronary arteries with prevailence of bridge-like obstructions in the anterior interventricular branch of the left coronary artery. Typical changes in cardiac angioarchitectonics indicating pronounced inadequacy of coronary blood flow were determined depending on the segmentary directionality of bridge obstruction. The data attest to pronounced pathogenetic role of myocardial bridges in sudden cardiac death.
确定了梗阻性肥厚型心肌病、高血压和缺血性心脏病患者中心肌桥的特征性发病率。心肌桥主要见于主要冠状动脉的中段，以左冠状动脉前室间支的桥状梗阻最为常见。根据桥状梗阻的节段性方向性，确定了提示冠状动脉血流明显不足的典型心脏血管构筑学改变。这些数据证明心肌桥在心脏性猝死中具有明显的致病作用。
