QSKL improved cardiac functions (n = 9). Parameters of cardiac functions were detected by echocardiography. (a) shows that LVEDd, LVEDs, EF, and FS were normal in the sham group. (b) shows that LVEDs were upregulated, while EF and FS were downregulated in the model group compared with the sham group. (c) shows that EF and FS were upregulated in the QSKL group compared with those in the model group. (d) shows that there was a modest improvement of EF and FS in the fosinopril group (^∗P < 0.05, ^∗∗P < 0.01, other groups versus model group).
