LGZG improved cardiac function. (a) Schematic of HF induction by DOX and the treatment protocol. (b) BNP level as determined by ELISA. (c) Representative echocardiographic images (scale bar, 0.5 cm). Ejection fraction (EF) and fraction shortening (FS), left ventricular end-systolic diameter (LVESD), and left ventricular end-diastolic diameter (LVEDD) are shown in (d), (e), (f), and (g), respectively. The experiment was performed in triplicate. Data are mean ± SEM, n = 8. The observer was blinded to the group assignment. NS, not significant
