    Abstract:
    Background The Garcinia kola seeds have been reported for its antibacterial, antioxidant, antidiabetic and also for its chemoprevention property. The use of doxorubicin as an anticancer drug has been accompanied with avalanche of side effects including cardiotoxicity. The aim of this study was to investigate the cardioprotective effect of Kolaviron and Garcinia kola and their mechanisms of action. Methods Sixty male rats (Wistar strain) were used in this study. They were divided into 6 groups (A-F) each containing 10 animals. Group A was the control. Rats in Groups B, C, D, E and F were treated with doxorubicin at the dosage of 15 mg/kg body weight i.p. Prior to this treatment, rats in groups C, D, E and F were pre-treated orally with Kolaviron at the dosage of 100 mg/kg and 200 mg/kg, and Garcinia kola 100 mg/kg and 200 mg/kg for 7 days, respectively. Results The results show that doxorubicin caused a significant increase in heart rate and prolonged QT, reduced antioxidant status, increased oxidative stress, inflammation and markers of cardiac damage which were reversed by pre-treatment with Kolaviron and Garcinia kola. Conclusions Overall, pre-treatment with Kolaviron or Garcinia kola caused reversal of cardiac damage, ECG alteration and oxidative stress by increasing the activity of antioxidant enzymes and reducing the markers of inflammation on doxorubicin-induced cardiotoxicity.
