摘　　要：目的：分析冠状动脉狭窄程度及左心室功能的变化与室壁瘤形成的关系。方法：对５６例室壁瘤的左室射血分数（ＥＦ）及冠状动脉百分直径狭窄进行定量。结果：全组平均ＥＦ值（４７±１４）％，其中１８例瘤体＞１／２左室腔者ＥＦ平均值仅为（３２±１０）％。室壁瘤累及前侧壁、心尖部共４８例（４８／５６，８６％），当中９２％前降支有梗阻性病变，重度狭窄或闭塞占９１％；结论：室壁瘤对左室功能的影响与瘤体大小和残余心肌的收缩力有关，而冠状动脉病变的分布范围及狭窄程度与室壁瘤形成有密切关系。Objective: Relation of degree of coronary artery stenosis, change of left ventricular(LV) function and LV aneurysm were studied. Methods: Quantitative analysis of LV ejection fraction(EF) and percent age of diameter of coronary stenosis was performed in 56 patients with LV aneurysm. Results: The average of EF was (47±14) % in all patients; (32±10)% in 18 patiets whose volume of LV aneurysm was greater than 50% of the LV volume. The anterolateral wall and /or apexl of the LV involved 48 cases (48/56, 86%); of which 92% were accompanied by LAD disease. Occlusion or high grade stenosis was detected in 91% of these patients with LAD disease. Conclusion:The size of the LV aneurysm and residual myocardial contractility affect LV function. The locations and degree of coronary artery stenosis are closely related to the pathogenesis of LV aneurysm.
