Active Comparator
Experimental
Routine-dose statin group
high-dose statin or PCSK9 inhibitor group
Routine-dose statin group will be gaven the treatment of atorvastatin 20mg Qd for 12 months
high-dose statin group will be gaven the treatment of atorvastatin 40-80mg Qd till 6 months at the moment the subjects will be followed up to determine plaques status by HRMRI examination, among which the subjects presenting culprit plaque progression with the significant increasing of plaque burden including intraplaque hemorrhage will be again randomized into two groups at a ratio of 1:1 as followed: atorvastatin-probucol group will be administrated atorvastatin 40-80mg Qd plus probucol 0.5g Bid till 12 months, the other group will maintain the original scheme till 12 months. PCSK9 inhibitor group will receive the subcutaneous injection of Evolocumab (140mg, 2 / month) for one year.
