缺氧性肺动脉高压是高原心脏病发生的中心环节,也是阻塞性肺疾患导致右心肥大以至衰竭的中心环节。此外,肺动脉高压还见于一此因素引起的急性肺损伤,而且还可能参与高原肺水肿的形成。对于缺氧性肺血管收缩机制的研究,其意义不仅限于理论上探讨,而且是 Hypoxic pulmonary hypertension is the central link in the development of high altitude heart disease and is also the central link of obstructive pulmonary disease leading to right ventricular hypertrophy and failure. In addition, pulmonary hypertension is also seen in acute lung injury caused by a factor, and may also be involved in the formation of high altitude pulmonary edema. For hypoxic pulmonary vasoconstriction mechanism research, its significance is not limited to the theoretical discussion, but also
