Pulmonary hypertension in hemodialysis patients.

The aim of this study was to evaluate the prevalence of primary pulmonary hypertension (PHT) among hemodialysis patients and search for possible etiologic factors. The prevalence of PHT was prospectively estimated by Doppler echocardiogram in 62 long-term hemodialysis patients on the day post dialysis. PHT (> 35 mm Hg) was found in 32 (51.

Pulmonary hypertension and predisposing factors in patients receiving hemodialysis.

Introduction: The aim of this study was to evaluate the frequency of unexplained pulmonary hypertension (PHT) among patients on hemodialysis at 2 centers and to evaluate possible predisposing factors.

Materials And Methods: In this cross-sectional study, PHT was screened by Doppler echocardiography on the day after dialysis in 62 patients with end-stage renal disease receiving maintenance hemodialysis via arteriovenous access. Pulmonary hypertension was defined as a systolic pulmonary arterial pressure (PAP) higher than 35 mm Hg, and the systolic PAP was calculated using the modified Bernoulli equation.
