The dose-dependent improvement of enlarged heart area, venous congestion, cardiac output, blood flow velocity, and heart rates in HF zebrafish treated with SYDC for 4 h. (A) The heart areas of the zebrafish in each group. (B) The venous congestion areas of the zebrafish in each group. (C) The cardiac output of the zebrafish in each group. (D) The blood flow velocity of the zebrafish in each group. (E) The heart rates of the zebrafish in each group. ###Compared with the normal control, p < 0.001; *compared with the model control, p < 0.05; ***compared with the model control, p < 0.001.
