E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect of the PCSK9 inhibitor alirocumab on the change in percent atheroma volume (PAV) at week 52 in patients with acute myocardial infarction undergoing percutaneous coronary intervention (PCI) in the infarct-related artery and receiving uidelinerecommended high-intensity statin therapy. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the effect of the PCSK9 inhibitor alirocumab on the change in lipid core burden index (defined by NIRS), macrophage accumulation, and fibrous cap thickness of coronary plaques (defined by OCT) as compared with placebo in the non-infarct-related coronary arteries; To assess the effect of alirocumab on change in lipid levels (cholesterol, LDL-C, HDL-C, Lp(a), triglycerides, non-HDL-C, Apo B, Apo A-1, ratio Apo B/Apo A-1, Apo C-III), inflammatory biomarkers (hs-CRP, TNFa, IL-1b, IL-6, MPO, cystatine, SIRT1, SIRT6) and other selected biomarkers (hs-troponin T, NT-pro-BNP) and explore possible associations with changes in coronary plaque characteristics; To evaluate adverse events in patients treated with alirocumab. |
