Abstract:Aim To study the effect of fluvastatin on cardiac remodeling and cardiac function, and to investigate the effect of matrix metalloproteinase-9 (MMP-9) and MMP-10. Methods 36 Wistar rats were randomly divided into acute myocardial infarction (AMI) group,AMI+fluvastatin group and the sham-operated group. AMI was established by ligation of the anterior descending coronary artery in rats, fluvastatin was fed to AMI+ fluvastatin group by 20 mg/(kg·d) for 6 weeks. After 6 weeks treatment, then the hemodynamic parameters and mass index of left ventricular and the expression of MMP-9 and MMP-10 were detected. Results Compared with the sham-operated group, left ventricular systolic pressure(LVSP) and the maximal rate of rise and fall (±dp/dtmax) of left ventricular pressure in the AMI group and AMI+fluvastatin group were all decreased(P<0.05), moreover,these indexes decreased significantly in AMI group than those in AMI+fluvastatin group(P<0.05). Compared with the sham-operated group, left ventricular end-diastolic diameter (LVEDD), left ventricular end systolic diameter (LVESD), left ventricular mass index (LVMI), MMP-9, MMP-10 were significantly increased in the AMI group and AMI+fluvastatin group moreover,these indexes decreased in AMI+ fluvastatin group than those in AMI group(P< 0.05). Conclusion Fluvastatin could prevent the cardiac remodeling, the mechanisms may be by reducing the levels of MMP-9 and MMP-10.
