Developmental phase



Assessment

Primary outcomes

Changes in the coronary plaque distribution and coronary plaque CT values

Key secondary outcomes

1) Changes in LDL-C, TG, HDL-C
2) Correlation between the absolute and percent changes of LDL-C and changes in the coronary plaque distribution
3) Correlation between the absolute and percent changes of LDL-C and changes in the coronary plaque density
4) Correlation between the absolute and percent changes in the blood test results (lipids, oxidative stress markers, adipocytokines) and changes in the coronary plaque distribution
5) Correlation between the absolute and percent change in the blood test results (lipids, oxidative stress markers, adipocytokines) and changes in the coronary plaque values
6) Incidence of major adverse cardiovascular events (MACE; defined as cardiac death, nonfatal MI, PCI or coronary artery bypass grafting, hospitalization due to angina, fatal or nonfatal stroke or TIA)
7) All-cause mortality
