[End-stage renal disease and pulmonary hypertension].

Pulmonary hypertension (PH) is a common complication in patients with end-stage renal disease (ESRD), especially in patients with hemodialysis (HD). Poor prognosis can eventually lead to right heart failure and even death. PH is an independent risk factor for increased mortality in ESRD patients. We should pay attention to these patients in clinic for early detection, prevention and treatment. The pathogenesis of PH in ESRD patients is still unclear so far, which might be related to the increase of pulmonary vascular resistance, pulmonary blood flow, and pulmonary arterial wedge pressure. In addition, the presence of risk factors can promote the development of PH, such as chronic hypoxia, vascular calcification, and inflammation.
