Abstract
Objective To study the effects of different doses of atorvastatin on serum homocysteine (Hcy) and matrix metallopmteinase-9 (MMP-9) in patients with acute cerebral infarction.Methods Ninety-patients with acute cerebral infarction were randomly divided into two groups,the observation group (n =45 cases) and the control group(n =45 cases).The patients in the observation group were treated by the conventional therapy plus atorvastatin 40mg/d,while the patients in the control group were treated by the conventional therapy plus atorvastatin 20mg/d.Hcy and MMP-9 were detected before and after treatment for one month.Results The total effective rate was 95.6％in the observation group and 86.7％ in the control group.There was significant difference between two groups(x2 =2.1951,P ＜ 0.05).Hcy and MMP-9 were decreased after treatment in both groups and those in the observation group were lower than in the control group (all P ＜ 0.05).Conclusion High-dose atorvastatin can improve patients with acute cerebral infarction through decreasing Hcy and MMP-9.
