Fig. 1: BEL improved cardiac function in ISO-treated mice.

A Representative images of ECG tracings in the different groups. B Representative images of ultrasound in different groups. C–J Changes in EF, FS, LVAWd, LVAWs, LVEDD, LVESD, LVPWd, and LVPWs in the different groups (n = 6). Data are shown as the mean ± SEM. Significance: *p < 0.05 vs CON group; **p < 0.01 vs CON group; # p < 0.05 vs ISO group; ## p < 0.01 vs ISO group; ns no significant difference.
