Successful establishment of HF dogs. (A) Echocardiography in HF and control groups. (B) The EF on the 1st and 4th week of HF. *p < 0.05, **p < 0.01. (C) Masson staining of the right ventricular myocardium of HF and control groups. **p < 0.01. Bar = 100 μm. (D) Levels of BNP and IL-17 in the plasma of HF and control groups. **p < 0.01. (E) The morphology of the right ventricular tissue under transmission electron microscopy. Bar = 500 nm.
