Effect of high rosuvastatin dose on outcome in patients with large artery atherosclerotic stroke / 中华老年心脑血管病杂志

ABSTRACT

Objective To study the effect of high rosuvastatin dose on outcome in patients with large artery atherosclerotic stroke (LAAS).Methods Eighty-two LAAS patients were randomly divided into high rosuvastatin dose group (n=39) and routine rosuvastatin dose group (n=43).Their serum blood lipid level and inflammatory indexes were measured and their clinical outcome was assessed.Results No significant difference was found in mortality,recurrence and hemorrhagic transformation between the two groups (P＞0.05).The rate of improved outcome was significantly higher in high rosuvastatin dose group than in routine rosuvastatin dose group (84.62％ vs 65.12％,P=0.04).The serum hs-CRP level was significantly lower in routine rosuvastatin dose group and high rosuvastatin dose group after treatment than before treatment (0.56±0.60 mg/L vs 0.70±0.68 mg/L,P=0.01;0.22±0.29 mg/L vs 0.69±0.58mg/L,P=0.00) and in high rosuvastatin dose group than in routine rosuvastatin dose group after treatment than before treatment (0.22±0.29 mg/L vs 0.56±0.60 mg/L,P=0.00).The rate of LDL C＜1.8 mmol/L and non HDL-C＜2.6 mmol/L was significantly higher in high rosuvastatin dose group than in rosuvastatin dose group after treatment (69.23％ vs 46.51％,P=0.04;66.67％ vs 41.86％,P=0.03).No significant adverse reactions occurred in both groups.Conclusion High rosuvastatin dose can effectively increase the blood lipid level,reduce the serum hs-CRP level,and improve the clinical outcome in LAAS patients.
