Brief Summary:
the purpose of this study is to show that alirocumab with statin therapy have a s tronger stabilizing effect on vulnerable plaque in coronary artery disease than statin alone administration

Condition or disease Intervention/treatment Phase
Coronary Artery Disease Thin-cap fIbroatheroma Drug: Alirocumab Phase 4

Detailed Description:
The investigators investigate to evaluate the efficacy of alirocumab for vulnerable plaque. The investigators enrolled the patient with standard statin therapy who were detected vulnerable plaque by optical coherence tomography, and categorized into two group; the patients with alirocumab and rosuvastatin were categorized alirocumab therapy group, and the patients with rosuvastatin alone were categorized standard statin therapy group. The investigators compare these two group for outcomes.

  6. the number of thin-cap fibroatheroma [ Time Frame: 9 month ]
  7. the change in lipid parameters [ Time Frame: 9 month ]
    including LDL-cholesterol, HDL-cholesterol, total-cholesterol, Lipoprotain(a)

  8. the change in hs-CRP [ Time Frame: 9 month ]
