The effect of non-dipper pattern of hypertension on erectile dysfunction

Abstract Background. The purpose of this study was to evaluate the relationship between erectile dysfunction (ED) and non-dipper pattern in hypertensive patients. Methods. A total of 750 consecutive patients with essential hypertension, who had been evaluated with ambulatory BP monitoring, were screened for this study. One hundred and thirty-two male patients (age range 28-54 years) who had fulfilled the inclusion and exclusion criteria were included in the final analysis. Dipper and non-dipper patterns were detected and sexual function was assessed by the self-administered questionnaire of the International Index of Erectile Function (IIEF). Results. There was no significant difference between the two groups regarding the number of medications taken and the proportion of each class of antihypertensive medications. Mean age, body mass index, lipid profiles, rate of smoking were similar between the two groups. IIEF score was significantly higher in non-dippers than dippers (p= 0.009). Non-dipping was also found to be an independent determinant for ED. Conclusion. The result of the present study further suggests that non-dipping is a risk indicator for early deterioration of erectile function in hypertensive patients.
