H&E staining showing the protective effect of AS-IV on transverse aortic constriction-induced HF. (A) Myocardial cells showed hypertrophy, disordered arrangement, increased intercellular stroma and inflammatory infiltration in the HF group, which were reversed by AS-IV. (B) Summarized data of H&E staining (n=6). Data are presented as the mean ± standard deviation. One-way analysis of variance, followed by Tukey's test. ^*P<0.05 vs. control; ^#P<0.05 vs. HF. AS-IV, astragaloside; HF, heart failure; DMSO, dimethyl sulfoxide.
