Primary Outcome Measures:
  • Percent change in total atheroma volume(TAV) [ Time Frame: 2 years ] [ Designated as safety issue: No ]
    Percent change in total atheroma volume(TAV) at region of interest defined as(TAV at 24 months-TAV at baseline)/(TAV at baseline)x 100

Secondary Outcome Measures:
  • Change in PAV(Percent atheroma volume) at region of interest [ Time Frame: 2years ] [ Designated as safety issue: No ]
    Change in PAV(Percent atheroma volume) at region of interest(PAV at 24months-PAV at baseline)

  • Change in overall TAV [ Time Frame: 2years ] [ Designated as safety issue: No ]
    Sum of TAV in all coronary segments

  • Change in TAV at region of interest [ Time Frame: 2years ] [ Designated as safety issue: No ]
    TAV at 24months-TAV at baseline

  • Change in overall CAC(coronary artery calcification) score [ Time Frame: 2years ] [ Designated as safety issue: No ]
    overall CAC score at 24months-overall CAC score at baseline

  • Change in number of segment of any coronary atherosclerotic plaques [ Time Frame: 2years ] [ Designated as safety issue: No ]
  • Percent change from baseline in lipid levels [ Time Frame: 2years ] [ Designated as safety issue: No ]

Ages Eligible for Study:   35 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Men or women at least 35 years of age
  • Mild CAD (nonobstructive coronary atherosclerotic plaques, lumen narrowing <50%) and CAC score <300 in at least one segment of proximal or mid-portion of major epicardial coronary arteries
  • LDL cholesterol <130mg/dl

Exclusion Criteria:

  • History of stable angina, or acute coronary syndrome
  • History of transient ischemic attack, or stroke
  • Chronic kidney disease (eGFR< 60ml/min)
  • Diabetes mellitus with microvascular complications or insulin therapy
  • Hypertriglyceridemia (triglyceride >500mg/dl)
  • Any statin therapy in the past 4 weeks
  • Planned cardiac surgery or planned major non-cardiac surgery within 6 months.
  • Chronic disease requiring treatment with oral, intravenous, or intra-articular corticosteroids (use of topical, inhaled, or nasal corticosteroids is permissible).
  • A diagnosis of cancer (other than superficial squamous or basal cell skin cancer) in the past 3 years or current treatment for the active cancer.
  • Any clinically significant abnormality identified at the screening visit, physical examination, laboratory tests, or electrocardiogram which, in the judgment of the Investigator, would preclude safe completion of the study.

  • History of adult asthma manifested by bronchospasm in the past 6 months, or currently taking regular anti-asthmatic medication(s).
  • Unwillingness or inability to comply with the procedures described in this protocol.
  • Positive pregnancy test (all female subjects of childbearing potential must have a urine ß-human chorionic gonadotropin(hCG) pregnancy test performed at Screening and/ or within 7 days prior to randomization) or is known to be pregnant or lactating.
  • Hypersensitivity to Crestor
  • Skeletal muscle disease
  • Combination use with cyclosporine
  • Galactose intolerance, Lapp lactose deficiency or glucose-galactose malabsorption
  • Combination use of protease inhibitor
