5. Study Description
Brief Summary
Objective: To evaluate the early effects of intensive lipid lowering treatments with ezetimibe/simvastatin (Vytorin®) for each component of coronary plaques.
Study Design
Prospective, randomized, single-center study of each 80 subjects enrolled
Subjects with acute coronary syndrome who meet all inclusion and exclusion criteria will be enrolled.
Eligible subjects will be randomized 1:1 to A) Ezetimibe/Simvastatin (n=80) vs. B) Pravastatin (n=80), and each group of patients will be randomized further in a ratio of 1:1 to a) ZES (n=40) vs. b) EES (n=40), according to the type of stent used.
All subjects will undergo VH-IVUS at initial procedure.
Follow-up VH-IVUS will be performed at 3 months after index procedure. OCT at initial procedure and 3-months will be performed in available cases.

Intervention Name(s)
Zotalolimus Eluting Stent
Intervention Description
Permuted block randomization into 4 groups according to the type of drug and stent will be carried out in a ratio of 1:1:1:1(i.e.,Vytorin-ZES, Vytorin-EES, mevalotin-ZES, or mevalotin-EES) for balanced randomization.
Patients with native coronary arteries who fulfill all enrollment criteria for OCT study will be randomized to receive either ZES (Endeavor®-Sprint or Resolute-integrity) or EES (Xience®) in a ratio of 1:1.
