冠状动脉瘤26例临床分析

Coronary artery aneurysm and its clinical analysis

目的 探讨冠状动脉造影的人群中冠状动脉瘤的发生率、病因、临床特点和预后。方法 回顾性总结 2 876例行冠状动脉造影人群。结果 2 876例行冠状动脉造影术的人群中 ,共检出冠状动脉瘤 2 6例 ,发生率为 0 90 4 % ,其中男性 2 0例 ,女性 6例。好发部位依次为RCA ,LAD ,LCX ,LM ;有心绞痛病史者 2 4例 ,14例合并心肌梗死 ;同时存有冠状动脉狭窄≥ 5 0 %的病人 2 4例 ;瘤体内发现血栓 2 0例 ;瘤体发生于单支冠状动脉者 2 1例 ,2支者 2例 ,3支并左主干者 2例 ;无一例瘤体破裂。本病可引起心肌梗死等严重临床后果 ,抗血小板、抗凝及血运重建可明显改善预后。结论 成年人冠状动脉瘤是冠状动脉粥样硬化的一个少见的亚类或变异型 ,非一个独立临床疾病 ,动脉瘤和狭窄通常是共有的。动脉瘤内常有血栓 ,易引起心肌梗死 ,如不积极干预 ,则愈后较差。

Objective To study the incidence of coronary artery aneurysm (CAA) in patients under coronary angiography (CAG), its clinic features and prognosis Methods Retrospective studies were conducted of the clinical features, treatment and outcome of 2?876 patients under CAG Results Among the 2?876 patients, 26 had CAA, the total incidence of CAA was 0 904% Among these patients, 14 had myocardial infarction, and 24 had narrowing coronary artery (stenosis≥50%) Among the 26 cases of CAA, 20 ateries had thrombosis No CAA had ruptured Conclusion The incidence of CAA in the studied CAG population was 0 904%, CAA could be responsible for myocardial ischemia and myocardial infarction
