Cardiac fibrosis and hypertrophy in the LV. (a) Representative macrophotographs of the aorta with Masson’s trichrome staining and quantification analysis for the percentage of fibrosis in each group. mRNA expression levels of (b) TGF-β and (c) MyH7 in each group are shown. TGF-β: transforming growth factor-beta; MyH7: myosin heavy chain 7; CTL: control group; VAL: valsartan group; SAC: sacubitril group; VAL/SAC: valsartan plus sacubitril group. CTL (), VAL (), SAC (), and VAL/SAC () were investigated. † and ‡ indicate significant differences compared with VAL and SAC, respectively.
