About this study
Official title: A Prospective, Randomized Study of Enhanced External Counterpulsation for Patients With Erectile Dysfunction
The purpose of this study is to investigate the efficacy of Enhanced External Counterpulsation (EECP) in patients with erectile dysfunction
Read the 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.
- Conditions
- Erectile Dysfunction
- Being tested
- Enhanced external counterpulsation
- Keywords
- Erectile Dysfunction, Vascular Endothelium, Counterpulsation, External
- Medical subject headings
- Erectile Dysfunction
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Enhanced external counterpulsationDevice
Also called EECP
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.
| Study group | Role | What they receive |
|---|---|---|
| Enhanced External Counterpulsation | Experimental | Men with erectile dysfunction receive Enhanced External Counterpulsation treatment Receives: Device: Enhanced external counterpulsation |
| Control | No intervention | Men with erectile dysfunction without Enhanced External Counterpulsation treatment |
What is being measured
The primary outcome is the main question the study is designed to answer.
Erectile function evaluated by International Index of Erectile Function-5 questionnaire
Measured: 7 weeks
Secondary outcomes (1)
Endothelial function
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
Measured: 7 weeks
