目的分析合并勃起功能障碍（ED）的男性冠心病患者冠状动脉造影表现。方法选择男性冠心病患者197例,接受冠状动脉造影检查和＂勃起功能障碍国际指数问卷表（IIEF-5）＂评估。结果 197例男性冠心病患者中合并ED患者112例（合并ED组,56.85%）,未合并ED的冠心病患者85例（对照组）;合并ED组3支病变29例,占25.89%,双支病变51例,占45.54%,平均病变支数5例,占5.88%,均明显多于对照组（36例,42.35%）,同时前者的单支病变32例,占38.79%,明显少于对照组44例,51.76%（P均〈0.01）;合并ED组冠脉重度狭窄27例,占24.11%,中度狭窄50例,占44.64%,以及冠脉狭窄程度评分系统评分（Gensini积分）均明显多于对照组（4例,4.71%和34例,40.00%）,同时前者的轻度狭窄35例,占31.25%,明显少于对照组47例,55.29%（P均〈0.01）。结论冠心病合并ED常常提示冠状动脉病变范围和程度均较重。

英文摘要：

Objective To elucidate the characteristics of coronary arteriography among the males with coronary artery disease（CAD） and erectile dysfunction（ED）.Methods A total of 197 CAD male patients were successively selected to participate an examination of coronary arteriography and a questionnaire survey with International Index of Erectile Function（IIEF-5）.Results All 197 males were divided into CAD ＋ ED group（complicated group,n=112,56.85%） and CAD group（control group,n=85）.Compared to the control group,the patients in complicated group showed higher proportions of two branches stenosis（45.54% vs 42.35%） and three branches stenosis（25.89% vs 5.88%）,and a lower proportion of single branch stenosis（38.79% vs 51.76%）（P0.01 for all）;in addition,the patients in complicated group had higher ratios of severe（24.11% vs 4.71%） and moderate（44.64% vs 40.00%） coronary artery stenosis and a lower ratio of minor coronary artery stenosis（31.25% vs 55.29%）（P0.01 for all） than the patients in the control group.Conclusion The CAD patients complicated with ED generally have more severe coronary artery disease than those without ED.
