Notes: sham: control group; model: model group; perindopril: perindopril group; LHF-L: low-dose LHF group; LHF-M: medium-dose LHF group; LHF-H: high-dose LHF group. Data are expressed as mean ± standard deviation (SD). compared with sham; compared with model; #, ## compared with perindopril; compared with LHF-H; compared with LHF-M. The analysis between groups of body weight and left ventricular weight accorded with normality and homogeneity of variance, so we used one-way ANOVA test. Body weight (F: 26.185, ); left ventricular weight (F: 23.655, ). The analysis between groups of heart weight, HW/BW, and LVW/BW did not conform to the normality and homogeneity of variance, so we used rank sum test of two independent samples and obtained the Z value. Heart weight (); HW/BW (); LVW/BW ().
