NCT01106495

Brief Summary

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

Study Arms (2)

Enhanced External Counterpulsation

EXPERIMENTAL

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)Drug: Simvastatin

Control

ACTIVE COMPARATOR

Subjects whose LDL higher than 160 mg/dl with subclinical atherosclerosis. Simvastatin is used to decrease cholesterol level for 7 weeks.

Drug: Simvastatin

Interventions

EECP one hour per day, 5 hours a week for a total of 35- 36 hours over a 7 week period

Also known as: EECP
Enhanced External Counterpulsation

Simvastatin 40 mg/d for 7 weeks as the guideline- driven standard medical treatment

Also known as: Statin
ControlEnhanced External Counterpulsation

Eligibility Criteria

Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

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

You may not qualify if:

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