Abstract:
Objective: To investigate the effects of rosuvastatin on reactive oxygen species (ROS) production and periostin, cardiotrophin-1 (CT-1) expression, and to explore rosuvastatin on ventricular remodeling in experimental rats after acute myocardial infarction (AMI). Methods: A total of 45 male Wistar rats were randomly divided into 2 group, Sham operation group,n=15 and AMI group,n=30, the AMI model was established by left anterior descending coronary ligation. After 24 hours of AMI, the rats were further divided into 2 groups, AMI + rosuvastatin group, the rats received gastric rosuvastatin 1mg/(kg?d), and AMI group, the rats received gastric normal saline.n=15 in each group and all animals were treated for 6 weeks. The mRNA and protein expressions of CT-1 and periostin were examined by real time RT-PCR and immunohistochemistry, the contents of superoxide anion (O2-·) and hydroxy radical (OH·) were detected by colorimetric method among different groups. Results: Compared with Sham operation group and AMI + suvastatin group, the mRNA and protein expressions of CT-1, periostin, the contents of (O2-·), (OH·) and left heart weight index were increased in AMI group at non-infraction zone,P<005. Compared with Sham operation group, the mRNA and protein expressions of CT-1, periostin, the contents of (O2-·), (OH·) and left heart weight index were increased in AMI + suvastatin group at non-infraction zone,P<005. Compared with AMI group, the mRNA and protein expressions of CT-1 and periostin were decreased in AMI + rosuvastatin group,P<005. Conclusion: Rosuvastatin may improve ventricular remodeling via inhibiting ROS production and CT-1, periostin expression in experimental rats after AMI.
