The Efficacy of Alirocumab for Thin-cap fIbroatheroma in Patients With Coronary Artery Disease Estimated by Optical Coherence Tomography

Phase 4
Conditions
Coronary Artery Disease
Thin-cap fIbroatheroma
Interventions
Registration Number
NCT03552432
Lead Sponsor
Kobe University
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

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.
