Possible Protective Mechanisms exerted by Metformin or Metformin and Vitamin E in Isoproterenol ‐Induced Cardiac Injury
This study was designed to investigate the cardioprotective effects of metformin with and without vitamin E after induction myocardial infarction (MI) in rats, using isoproterenol. Administration of metformin or vitamin E significantly reduced the cardiac mass index (P<0.01), ameliorated the changes to cardiac biomarkers, and attenuated oxidative stress levels compared to the isoproterenol group. Interestingly, combination therapy showed a slight synergistic effect. Histopathological analysis suggested that metformin treatment reduced NF‐κB expression and protected against isoproterenol‐induced MI. Our results indicate that metformin mediates a cardioprotective effect against isoproterenol‐induced MI via antioxidant activity and modulation of the NF‐κB signaling pathway. This suggests that metformin would be beneficial in MI treatment. This article is protected by copyright. All rights reserved
