【摘要】:正低氧性肺动脉高压(HPH)是长期缺氧引起的,以渐进性肺血管阻力升高为主要特征,导致右心室肥厚和纤维化,进一步致右心功能不全和不可逆的右心衰竭,甚至全心衰竭,具有较高的病死率。既往研究阐述了HPH的发病关键在于缺氧引起的肺血管收缩及肺血管重塑,可能涉及血管有肺静脉~([1])及肺动脉的中膜平滑肌细胞和外膜成纤维细胞,但不包括肺动脉的内膜内皮细胞~([2])。其中,肺动脉平滑肌细胞增殖是HPH的主要
[Abstract]:Positive hypoxic pulmonary hypertension (HPH) is caused by long-term hypoxia. It is characterized by progressive pulmonary vascular resistance increase, leading to right ventricular hypertrophy and fibrosis, and further leading to right ventricular insufficiency and irreversible right heart failure, or even total heart failure. It has a high mortality rate. Previous studies have demonstrated that the key to the pathogenesis of HPH is hypoxia induced pulmonary vasoconstriction and pulmonary vascular remodeling, which may involve pulmonary vein ~ (1) and pulmonary artery medial smooth muscle cells and adventitia fibroblasts. But the intima endothelial cells excluding pulmonary artery were ~ (2). The proliferation of pulmonary artery smooth muscle cells is the main factor in HPH.
