Abstract Background:Pulmonary arterial hypertension is a newly recognized disease in patients
with renal disease. In a recent review, the prevalence of PHT in ESRD patients was reported to be
around 40–50%.
Aim of the work:To evaluate the prevalence of primary pulmonary hypertension among CKD
patients on and without dialysis and to compare clinical, hemodynamic, and metabolic variables
among patients with and without PH to search for possible etiologic factors.
Patients and methods:Our study included 99 CKD patients; 65 patients on hemodialysis, 12 on
peritoneal dialysis and 22 on conservative management. Detailed medical history, examination, and
complete laboratory investigations were obtained. Systolic PAP, EF% and cardiac output were
evaluated by Doppler echocardiography and AVF flow by Doppler ultrasound.
