NMR-based metabolomics approach was used to elucidate the cardioprotective mechanisms of XST.
XST modulates the metabolic changes caused by I/R injury in three energy metabolism related pathways.
Pearson correlation was used to interpret the biological functions of candidate metabolites.
Elevated pyruvate was found as an essential metabolic response of XST treatment.
XST removes ROS to restore the TCA cycle activity and achieve therapeutic effects.
