Effects of QSG on myocardial morphological injury in HF rats after AMI. Myocardial samples of the four groups surrounding an area of infarction, visualized via hematoxylin–eosin staining (400×). The cardiomyocytes in the sham group were orderly arranged and the nuclei were lightly stained. The myocardial tissue in the model group exhibited obvious pathological abnormalities with pyknotic dark-staining nuclei and inflammatory cell infiltration. QSG and fosinopril could attenuate cellular degeneration and inflammatory cell infiltration
