Effect of SXT on myocardial energy metabolism in CHF rats. A The concentration of FFAs in the serum of all rats was examined using a specific kit. B The concentration of LA in the serum of all rats was examined using a specific kit. C Western blotting was performed to measure the expression of GLUT4 and CPT-1 in myocardial tissue. D Western blotting was performed to measure the expression of mtTFA, NRF-1, PGC‑1α, p-AMPK and AMPK in myocardial tissue. **P < 0.01 compared with the sham group. #P < 0.05 and ##P < 0.01 compared with the model group. \(\Delta\)P < 0.05 and \(\Delta \Delta\)P < 0.01 compared with the positive group
