AS-IV alleviated myocardial histomorphological changes in CHF rats. (a,b) Representative images of HE staining. (c,g) Representative images and quantification of the cardiomyocyte cross-sectional area in the non-infarcted zone (n = 3). (d,h) Representative images of Masson staining and quantification of the left ventricular infarct size (n = 3). (e,i) Representative images and quantification of the fibrosis in the infarcted border zone (surgical area for the Sham group, n = 3). (f,j) Representative images and quantification of the fibrosis in the non-infarcted zone (n = 3). **P < 0.01 vs. Sham group; ^##P < 0.01 vs. Model group.
