目的:分析颈动脉内膜中层厚度 (C-IMT) 与国际勃起功能指数-5 (IIEF-5) 评分、血管内皮功能 (FMD) 间的相关性.方法:分析2017年2月～2018年3月来我中心行C-IMT检查的362例男性健康体检数据.按C-IMT测量值1.0mm为分割点, 分为C-IMT0.05), 但C-IMT≥1.0mm组受试者的吸烟率及饮酒比例均高于C-IMT<1.0mm组 (P<0.05).Pearson相关性分析显示, C-IMT与IIEF-5呈负相关 (r=-0.477, P<0.001), C-IMT与FMD值呈负相关 (r=-0.466, P<0.001), FMD值与IIEF-5呈正相关 (r=0.549, P<0.001).结论:通过本研究发现C-IMT与男性勃起功能及血管内皮功能均呈负相关, 但C-IMT是否能预测男性的勃起功能及血管内皮功能仍需进一步研究证实.“,”Objective:To investigate the relationship between carotid intima-media thickness (C-IMT) and male erectile function (IIEF-5), vascular endothelial function (FMD).Method:From February, 2017 to March, 2018, 362 healthy males who received the C-IMT in our centre were enrolled in this study.These patients were divided into two groups based on the C-IMT value (C-IMT<1.0 mm and C-IMT≥1.0 mm group).Their age, BMI, blood pressure, serum creatinine, uric acid, cholesterol, blood glucose, triglyceride, low density lipoprotein, high density lipoprotein were compared between two groups.Moreover, the relationship among C-IMT, IIEF-5, FMD value were analyzed by correlation Pearson analyzation.Result:There was no statistic difference in their age, BMI, blood pressure, serum creatinine, uric acid, cholesterol, blood glucose, triglyceride, low density lipoprotein, high density lipoprotein between C-IMT0.05).However, there were more men who smoked and drank in the C-IMT≥1.0 mm group (P<0.05).By the Pearson correlation analyzation, C-IMT was negatively related to the IIEF-5 and FMD value (r=-0.477,-0.466, respectively, P<0.001).Moreover, IIEF-5 was positively related to the FMD value (r=0.549, P<0.001).Conclusion:C-IMT was negatively related to the male erectile function and vascular endothelial function.But whether C-IMT could act as a predictor for male erectile function and vascular endothelial function needs further studies.
