SIRT1 and myocardial infarction: The goal of this pilot study is toinvestigate temporal changes of serum sirtuin 1,3 and 6 levels in AMI patients, todetermine if there is any difference in serum sirtuin 1,3 and 6 levels between AMIpatients and control subjects and to investigate the association between serumsirtuin 1,3 and 6 levels and prognostic markers of AMI patients like peak serumtroponin levels, serum pro-BNP levels, GRACE score and post-MI LVEF.
