Acute myocardial infarction is a major cause of death and disability worldwide. This study was designed to elucidate the effect of resveratrol (RES) in isoproterenol (ISO)-challenged myocardial injury in rats. Male Sprague-Dawley rats were randomly allocated to four groups (10 rats/group): negative, control positive ISO (85?mg/kg), Propranolol/ISO, and RES/ISO. RES (50?mg/kg) improved plasma lactate dehydrogenase, creatine kinase, and cardiac troponin T; brain natriuretic peptide, interleukin-10, vascular endothelial growth factor, and transforming growth factor-β1; as well as cardiac superoxide dismutase, malondialdehyde, and total protein kinase-1 (Akt-1) levels. In addition, RES reduced the expression of cardiac inducible nitric oxide synthase and microRNA-34a, as well as p38 mitogen-activated protein kinase levels compared with positive control group. In conclusion, RES could reduce the degree of MI induced by ISO by improving the antioxidant, antiapoptotic, and anti-inflammatory capacities of the body.
