Objective:To investigate the effect of simvastatin on cardiomyocyte apoptosis and cardiac dysfuction after myocardial infarction.Method:Simvastatin was administrated to the rats with myocardial infarction which was modeled by left anterior descending coronary artery ligation. After 7days
the apoptotic myocyte cells were quantified by TUNEL staining;left ventricular function index was measured by echocardiography and the level of serum lipid was measured by biochemical method.Results:Compared with infarction group
apoptotic myocyte cells in simvastatin group significantly decreased in infarction zone
border zone and non-infarction zone(P<0.05)
and left ventricular function was improved significantly(P<0.05).There was no difference in the level of serum lipid between the groups(P>0.05).Conclusion:Simvastatin inhibits cardiomyocyte apoptosis and improves cardiac function after myocardial infarction.
