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

    Change from baseline in vascular endothelial function evaluated by flow mediated dilation of the brachial artery

  • Change in serum markers of inflammation [ Time Frame: 7 weeks ]
    Change from baseline in serum markers of inflammation and laboratory parameters

Estimated Enrollment: 150

Estimated Study Completion Date: March 2018
Estimated Primary Completion Date: October 2017 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
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.
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
Active Comparator: Control
Subjects whose LDL higher than 160 mg/dl with subclinical atherosclerosis. Simvastatin is used to decrease cholesterol level for 7 weeks.
Drug: Simvastatin
Simvastatin 40 mg/d for 7 weeks as the guideline- driven standard medical treatment
Other Name: Statin

Detailed Description:
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.

Ages Eligible for Study:   20 Years to 70 Years   (Adult, Senior)

Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • 20- 70 years old subjects whose LDL higher than 160mg/dl and carotid intima-media thickness higher than 75 percent of his age.

Exclusion Criteria:

  • Presence of history of coronary heart disease, stroke or atherosclerotic peripheral disease. Presence of impaired renal function, connective disease, or infectious disease.
