Pulmonary hypertension (PH) is a prevalent complication among patients with chronic kidney disease (CKD). In these patients, pulmonary vasodilators may be useful but are underused. We describe a group of patients with precapillary PH and advanced CKD treated with pulmonary vasodilators. This was a case series of patients with CKD stage 4 and 5 and precapillary PH (isolated or combined) based on right heart catheterization (RHC) treated with pulmonary vasodilators from 2018 to 2023. Of 263 patients with isolated precapillary or combined PH and advanced CKD, only 17 (6%) were treated with pulmonary vasodilators; 53% (n = 9) with precapillary PH and 47% (n = 8) with combined PH. Most patients (94%, n = 16) received phosphodiesterase-5 antagonists, while 12% (n = 2) received endothelin receptor antagonists. Adverse clinical outcomes were seen in 35% of patients within a year. The use of pulmonary vasodilator did not prevent adverse outcomes in patients with precapillary PH and advanced CKD.
