Relevant factors of pulmonary arterial smooth muscle cells proliferation and pulmonary arterial hypertension / 中华实用儿科临床杂志

Pulmonary arterial hypertension (PAH)is a disease of unknown etiology that leads to a progressive increase in pulmonary vascular resistance (PVR),if untreated,ultimately right heart failure and high mortality.It is concerted pulmonary vascular contraction and vascular remodeling are the 2 main courses of physiology and pathology leading to PAH,especially the significant role of proliferation of pulmonary arterial smooth muscle cells.A lot of relevant factors are revealed to take a participation into regulating the proliferation of pulmonary arterial smooth muscle cells and finally PAH.
