Early PCSK9 Inhibitor on Ventricular Remodling

This is a prospect, multi-center, random study to investigate whether early offering PCSK9 inhibitor to acute myocardium infarction(AMI) can alleviate ventricular remodeling after primary percutaneous intervention(PPCI). Totally,twenty acute myocardium infarction subjects will be enrolled in this study after consent information. After randomization, the control group will receive standard therapy for AMI including PPCI. The experiment group will receive first PCSK9 inhibitor before PPCI, then twice a month until 3 months later. Six month after AMI, Myocardial salvage index will be used to evaluate ventricular remodeling. TnI peaking time and LDL control rates also will be recorded and compared.
