Effect of Enhanced External Counterpulsation (EECP) on Subclinical Atherosclerosis
Study of the Effect of EECP on Subclinical Atherosclerosis
Shear stress maybe the most crucial local factor affecting atherogenesis. The present study investigated the effect of exposure to increased shear stress promoted by Enhanced External Counterpulsation (EECP) on the progression of subclinical atherosclerosis and the underlying inflammation- related molecular mechanisms
Hypercholesterolemic subjects with subclinical atherosclerosis will be randomized into two groups: standard treatment group and standard treatment plus EECP intervention group. The results of ultrasound examination and markers of inflammations will be compared.
Interventional

Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: No masking
Primary Purpose: Treatment
Atherosclerosis
  • Device: Enhanced External Counterpulsation (EECP)
    EECP one hour per day, 5 hours a week for a total of 35- 36 hours over a 7 week period
    Other Name: EECP
  • Drug: Simvastatin
    Simvastatin 40 mg/d for 7 weeks as the guideline- driven standard medical treatment
    Other Name: Statin
  • Experimental: Enhanced External Counterpulsation
    Enhanced external counterpulsation (EECP) is a noninvasive therapy for the treatment of patients with coronary artery disease.The systolic deflation/diastolic inflation sequence of EECP leads to systolic unloading and diastolic augmentation, resulting in increased blood flow in a pulsatile manner. Patients with subclinical atherosclerosis whose serum LDL high than 160mg/ml receive EECP 1- hour session every working day over a 7 week period. Simvastatin is used to decrease cholesterol level for 7 weeks.
    Interventions:
    • Device: Enhanced External Counterpulsation (EECP)
    • Drug: Simvastatin
  • Active Comparator: Control
    Subjects whose LDL higher than 160 mg/dl with subclinical atherosclerosis. Simvastatin is used to decrease cholesterol level for 7 weeks.
    Intervention: Drug: Simvastatin
