Protective Effects of Different Doses of Atorvastatin Pretreatment on Patients Underwent Percutaneous Coronary Intervention / 中国药房

ABSTRACT

OBJECTIVE:To investigate protective effects of different doses of atorvastatin pretreatment on non-ST-segment elevation acute coronary syndrome (NSTE-ACS) patients underwent percutaneous coronary intervention (PCI). METHODS:A total of 81 NSTE-ACS patients in a hospital during Jan. 2014-Apr. 2016 were divided into high-dose group(40 cases)and low dose group(41 cases)according to random number table. High-dose group was given Atorvastatin calcium tablet 80 mg 12-24 h before PCI,and then 40 mg 2 h before PCI. Low-dose group was given Atorvastatin calcium tablet 10 mg 12-24 h before PCI. Fractional flow reserve(FFR),coronary flow reserve(CFR)and index of microcirculation resistance(IMR)after surgery were all observed in 2 groups. The levels of creatine kinase(CK),creatine kinase myocardial band(CK-MB)and high sensitive C-re-active protein (hs-CRP) were compared between 2 groups before and after surgery. RESULTS:There was no statistical signifi-cance in FFR and CFR after surgery between 2 groups (P>0.05);IMR of high-dose group was significantly lower than low-dose group,with statistical significance(P<0.05). There was no statistical significance in CK,CK-MB or CRP between 2 groups before surgery(P>0.05). After surgery,the levels of CK-MB and CRP in low-dose group were significantly higher than high-dose group,with statistical significance(P<0.05). There was no statistical significance in CK level between 2 groups after surgery (P>0.05). No obvious ADR was found in 2 groups. CONCLUSIONS:During PCI,pre-treatment with high-dose of atorvastatin(80→40 mg)could effectively improve microcirculatory disturbance and inhibit inflammatory reaction of NSTE-ACS patients.
