Characteristics of coronary arteriography among males with coronary artery disease and erectile dysfunction

ObjectiveTo elucidate the characteristics of coronary arteriography among the males with coronary artery disease(CAD)and erectile dysfunction(ED).MethodsA 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).ResultsAll 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%)(P<0.01 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%)(P<0.01 for all)than the patients in the control group.ConclusionThe CAD patients complicated with ED generally have more severe coronary artery disease than those without ED.
