Figure 1: Indicators of heart functions in three groups of rats. LVEF, LVFS, LVID;s, and LVID;d in the model group were significantly changed compared with those in the sham group ( in each group, ). In the DQP-treated group, LVEF and LVFS were significantly upregulated compared with the model group (). LVID;d and LVID;s in the DQP-treated group were also downregulated, though the difference of LVID;d was not statistically significant. versus sham group; versus model group; versus model group.
