Özet
We aimed to investigate the potential benefits of two doses of ivabradine (IVA)-an If sodium channel blocker against isoproterenol (ISO)-induced myocardial damage in rats.The rats were randomly divided into 4 groups: Control group (n=8); Saline was administered, ISO group (n=12); 150 mg/kg ISO was administered for 2 days, ISO+IVA (1 mg/kg) group (n=12); 1 mg/kg IVA was administered for 4 days in addition to ISO. ISO+IVA (10 mg/kg) group (n=12): 10 mg/kg IVA was administered for 4 days in addition to ISO. Thereafter, hemodynamic, histopathological, and biochemical studies were performed. In the ISO+IVA (1 mg/kg) and ISO+IVA (10 mg/kg) groups, ISO-induced myocardial changes including an increase in density of granulation tissue and degenerated cardiomyocyte were equally decreased. HR was mildly reduced, and arterial blood pressures were slightly increased in the IVA-treated groups versus the ISO group. In the hearts of IVA-treated groups, malondialdehyde (MDA) levels were significantly reduced and glutathione (GSH) level and catalase (CAT) activity were mildly increased compared to the ISO group. Elevation of GSH and CAT activity were more pronounced in the ISO+IVA (10 mg/kg) group. Our results indicate that both 1 mg/kg and 10 mg/kg doses of IVA are effective against heart damage induced by ISO via its negative chronotropic, anti-oxidant (dose-dependent), anti-inflammatory and anti-degenerative properties.
