本文分析２３例冠心病患者的电影摄影所见，着重分析室壁瘤形成与冠状动脉狭窄的程度、部位、数目、侧支血管形成和临床病情等因素的关系。此外，对冠心病中继发二尖瓣返流的成因和机制进行了探讨。讨论中提出以下几点：（１）室壁瘤的发生与冠状动脉主要分支的严重狭窄关系最密切；（２）侧支循环能防止心肌梗塞范围扩大及室壁瘤形成；（３）二尖瓣返流与主要冠状动脉病变的狭窄程度及室壁瘤的存在有关。并对影响侧支循环显示的因素进行了探讨。
This paper analyzes the 23 cases of coronary heart disease seen in the film photography, focusing on the analysis of the formation of aneurysm and coronary stenosis degree, location, number, collateral vessel formation and clinical conditions and other factors. In addition, the causes and mechanisms of secondary mitral regurgitation in coronary heart disease were discussed. The discussion proposed the following points: (1) The occurrence of aneurysms is most closely related to severe stenosis of the major branches of coronary arteries; (2) collateral circulation prevents the expansion of myocardial infarct size and the formation of aneurysm; (3) Valvular regurgitation is associated with the degree of stenosis of major coronary lesions and the presence of aneurysm. The factors affecting the display of collateral circulation were also discussed.
