Changes in pulmonary artery systolic pressure and right ventricular function in patients with end-stage renal disease on maintenance dialysis.

Aim: Pulmonary hypertension is common in patients with end-stage renal disease, and portends a poor prognosis. There are little data in this population, and previous studies have not evaluated quantitative changes in haemodynamics over time while on maintenance dialysis. This study sought to estimate changes in pulmonary artery systolic pressure (PASP) and right ventricular function over time, and to predict PASP change using clinical variables routinely available at time of initial measurement, in patients on maintenance dialysis.
