Validation of pulmonary artery hypertension in hypoxia-treated rats. a, b Representative right ventricular pressure (RVSP) recorded from control and hypoxic rats. c Right ventricular mass index (RVMI) showed right ventricular hypertrophy, as indexed by the right ventricle/(left ventricle + ventricular septal) [RV/(LV + S)] mass ratio. d Comparison of the PAs from the hypoxic group and with those from the normoxic control group, as assessed by the hematoxylin–eosin staining of paraffin sections
