Abstract:
0.05).Compared with those in Sham group,LVWI,the typeⅠCVF,type Ⅲ CVF andⅠ/Ⅲ ratio in NIZ were increased significantly in MI group.Compared with those in MI group,the LVWI,the type ⅠCVF,type Ⅲ CVF andⅠ/Ⅲ ratio in NIZ were decreased significantly in Sim groups(but higher than those in Sham group).Compared with MI groups,left ventricular function in rats treated with simvastatin was also obviously improved.(2) Contrasted to those in MI group,the expressions of TGF-?1 and Smad3 were down-regulated in simvastatin treatment groups(but higher than those in Sham group).Conclusions Sim can ameliorate ventricular remodeling and ventricular function in rats induced by MI,and the mechanisms can be independent of its lipid-lowering and associated with inhibition of TGF-?1/Smad3 signal transduction.
