Myocardial Ischaemic Syndrome

This is a multi-center, randomized controlled study to investigate whether early offering PCSK9 inhibitor can protect against negative inflammatory response and organ dysfunction after coronary artery bypass grafting (CABG). Subjects with myocardial ischaemic syndromes (MIS) will be enrolled in this study after consent information. After randomization, the control group will receive standard therapy, while the experiment group will receive first PCSK9 inhibitor before CABG, then twice a month until 3 months later. Six month after CABG, CRP will be used to evaluate inflammation, and echocardiography and coronary CTA will be used to evaluate cardiovascular function.
