Brief Summary:
The purpose of this study is to investigate the efficacy of Enhanced External Counterpulsation (EECP) in patients with erectile dysfunction

Condition or disease Intervention/treatment Phase
Erectile Dysfunction Device: Enhanced external counterpulsation Not Applicable

Detailed Description:
Patients with erectile dysfunction will be randomized into two groups: EECP intervention or not. Erectile function, hemodynamic parameters, vascular endothelial function will be measured and compared.

Arm Intervention/treatment
Experimental: Enhanced External Counterpulsation
Men with erectile dysfunction receive Enhanced External Counterpulsation treatment
Device: Enhanced external counterpulsation
Enhanced external counterpulsation therapy is done by sequential inflation of 3 sets of cuffs wrapped around the lower extremities during diastole and deflation of the cuffs during systole. The systolic deflation/ Diastolic inflation sequence of EECP leads to systolic unloading and diastolic augmentation, resulting in increased blood flow in a pulsatile manner. The patients receive 35-36 hours EECP intervention, 1 -hour session every day over a 7-week period.
Other Name: EECP

No Intervention: Control
Men with erectile dysfunction without Enhanced External Counterpulsation treatment

Primary Outcome Measures :
  1. Erectile function evaluated by International Index of Erectile Function-5 questionnaire [ Time Frame: 7 weeks ]

Secondary Outcome Measures :
  1. Endothelial function [ Time Frame: 7 weeks ]
    Flow-mediated dilation:In this method,brachial artery diameter is measured before and after an increase in shear stress that is induced by reactive hyperemia (FMD). Endothelial progenitor cells:Flow cytometry to detect changes in the number of endothelial progenitor cells
