【摘要】 目的分析冠状动脉迂曲的检出率及其和冠状动脉粥样硬化(AS)的关系和预后。方法以35例冠状动脉迂曲患者为研究对象,回顾性查阅病史资料和心导管室的数据库;应用Logistic回归法分析年龄、性别、冠心病危险因素、冠状动脉迂曲程度对冠状动脉迂曲近段AS病变的影响;并对患者进行电话或门诊随访。结果本研究中冠状动脉迂曲的检出率为16.43%;通过多因素分析得出年龄、性别、高血压、糖尿病、吸烟史是冠状动脉迂曲近段发生AS病变较强的独立危险因素,冠状动脉迂曲程度也是独立危险因素,但其作用相对较弱,OR值为1.030(95%CI:1.011~1.050);随访期间无患者死亡,无急性心肌梗死发生。结论除了传统的粥样硬化危险因素外,冠状动脉迂曲程度是发生粥样硬化的独立危险因素,其长期预后通常是好的。更多还原

【Abstract】 Objective To analyze the prevalence and prognosis of coronary artery circuity(CAC),the relationship between CAC and atherosclerosis in the segment proximal to the circuity.Methods 35 patients who were detected as CAC were enrolled.The data was obtained from medical history and coronary angiography.Clinical and angiographic characteristics of both groups were compared and investigated to find out risk factors for atherosclerosis.All patients were fFollowed-up by telephone or clinic visit.Results The incidence of CAC by angiography was about 16.43%.Multivariate Logistic regression analysis showed that age,gender,hypertension,diabetes mellitus and smoking were the independent risk factors for atherosclerosis in the segment proximal to the CAC.And the degree of CAC was also the independent risk factors for atherosclerosis.The odds ratio was 1.030(95%CI:1.011-1.050).During follow-up period,there was no cardiac death happened.Conclusion The degree of CAC is the independent risk factors for atherosclerosis.The prognosis of the patients with CAC seems good.更多还原
