Abstract
Anticoagulant therapy can significantly reduce the incidence of stroke and peripheral embolism events in patients with atrial fibrillation (AF). Although warfarin is widely used as an anticoagulant drug, a wrong dose can lead to increased risks of bleeding or blood clots. The aim of this study was to assess whether nuclear factor-erythroid-2-related factor 2 (Nrf2) can improve the efficacy of warfarin through the regulation of cytochrome P450 family 2 subfamily C member 9 (CYP2C9) using a rat model of AF. Results showed that AF significantly reduced Nrf2 in myocardial tissue of sham-operated rats. Furthermore, Nrf2 overexpression effectively reduced AF-induced atrial fibrosis by reducing collagen in the left atrium, inhibiting the expression of the fibrosis-related genes collagen I and transforming growth factor-β1 in rats with AF. Nrf2 overexpression can activate CYP2C9, decrease the serum concentration of warfarin, and decrease prothrombin time and international normalized ratio in AF rats. In this article, Nrf2 overexpression protects against fibrosis, increased survival in AF rats, and activated CYP2C9 expression, thus broadening the therapeutic range of warfarin in AF rats.
