Representative histological sections and ECV(%)-fibrosis(%) scatterplot. a, b Representative Masson trichrome-stained sections of control group and HFpEF group. The extent of fibrosis was significantly higher in HFpEF hearts (11.7% ± 1.9%) than in control hearts (3.4% ± 0.8%), P < 0.001. c ECV values and the extent of fibrosis showed a moderate correlation: R = 0.59, P = 0.0098
