Changes in mPAP (a), RVHI (b), WT% (c), and WA% (d) in monocrotaline-induced rat PAH model. mPAP: mean pulmonary artery pressure; RVHI: right ventricle hypertrophy index; WT%: the ratio of vessel wall thickness and wall diameter; WA%: the ratio of vessel wall area and total vessel area. ∗ P < 0.05, ∗∗ P < 0.01.
