冠心病的电影摄影诊断（附23例报告）

Cine Coronary Angiographic Diagnosis of Coronary Heart Disease

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理进行了探讨。讨论中提出以下三点：（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。

Twenty-three cases of cine coronary angiographic findings were reported.The relationship between ventricular aneurysm and the degree, location, number of coronary arterial stenosis,collateral circulations, clinical data were particularly analysed. The mechanism of secondary mitral regurgitation in coronary heart disease was discussed too. The authors suggested following viewpoints: (1) There was a close relationship between the ventricular aneurysm and the severity of main coronary arterial stenosis; (2) The presence of collateral circulation may prevent the enlargement of the infarctive area and the formation of the aneurysm; and (3) Mitral regurgitation was related to the degree of coronary stenosis and the presence of ventricular aneurysm. At last, the factors that influenced the appearance of collateral circulation was discussed.
