肺动脉高压是一种以肺血管阻力持续升高为特征的临床疾病，其在维持性血液透析患者中很常见，并与高死亡率相关，但其发病机制未明，临床症状隐匿。因此，本文就国内外关于维持性血液透析患者肺动脉高压的研究进展作一综述，为维持性血液透析患者的肺动脉高压提供早期诊断和治疗的依据。

Pulmonary hypertension is a clinical disorder characterized by the continuing hyper-resistance of pulmonary vessels. Pulmonary hypertension is frequently encountered in maintenance hemodialysis (MHD) patients with a higher mortality rate. The mechanism of the disorder is yet unknown, and its clinical presentations are insidious. Here we summarize the recent progresses in pulmonary hypertension in MHD patients in China and foreign countries, so as to provide references for early diagnosis and management of pulmonary hypertension in MHD patients.
