单纯性冠状动脉扩张的临床分析

Clinical analysis of isolated coronary artery ectasia

目的研究单纯性冠状动脉扩张的发生率、影像学及临床特点、预后.方法回顾性总结分析自1998-02～2004-06期间在哈尔滨医科大学第一临床医学院行选择性冠状动脉造影术的2863例冠状动脉造影人群.结果 2863例行选择性冠状动脉造影术的人群中,共检出单纯性冠状动脉扩张20例,发生率0.698%;好发部位依次为左主干、右冠状动脉、前降支、回旋支;大多数单纯性冠状动脉扩张的病人是男性(85%)、吸烟者(90%);随访期间1例死亡,2例发生心肌梗死,12例仍有阵发性心绞痛发作;糖尿病是与单纯性冠状动脉扩张呈负相关的独立因素.结论单纯性冠状动脉扩张在冠状动脉造影中少见,与除糖尿病外所有冠心病的危险因素相关.单纯性冠状动脉扩张不是良性病变,必须小心监控.

Objective To study the incidence of isolated coronary artery ectasia, its clinical and angiographic characteristics, and its prognosis.Methods Retrospective studies were conducted in the 2 863 patients underwent coronary angiography from February 1998 to June 2004 in the Fast Hospital of Harbin Medical University, Results The rate of isolated coronary artery ectasia was 0.698%（20/2863）, Most patients with isolated coronary artery ectasia were men （85%）, smokers （90%）, It showed that diabetes was the only variable independently related with the absence of isolated coronary artery ectasia. Conclusion Isolated coronary artery ectasia is unusual in the patients underwent coronary angiography and associated with the traditional risk factors, except diabetes, Isolated coronary artery ectasia is not benign and must be carefully monitored.
