By analyzing coronary angiograms and ventriculograms of 61 patients with the narrowed lumen of one or several coronary vessels by 90-100%, the dependence of the contractile function of the myocardium on the development of the collateral circulation in the cardiac muscle was studied. The assessment of the segmentary contractility of the left ventricle served as a criterion of the efficiency of the collateral circulation. The segmentary contractility was shown to be dependent on the presence or absence of the collateral circulation and also on the number of damaged vessels. The collateral circulation was also demonstrated to contribute to the maintenance of the contractile function of the myocardium.
通过分析61例一根或几根冠状动脉管腔狭窄90%-100%患者的冠状动脉造影和心室造影，研究了心肌收缩功能对心肌侧支循环发育的依赖性。左心室节段性收缩力的评估作为侧支循环效率的标准。结果表明，节段性收缩力取决于侧支循环的有无以及受损血管的数量。还证明侧支循环有助于维持心肌的收缩功能。
