Echocardiographic examinations were performed. PHT was defined as systolic pulmonary artery pressure [sPAP] higher than 35 mmHg at rest.Results: sPAP, OH/ECW levels and the frequency of PHT were significanly reduced after HD . OH/ECW and the frequency of fluid overload were significantly higher in patients with PHT than in those without, whereas serum albumin and haemoglobin levels were significantly lower .View this table:Table 1 View this table:Table 2 Conclusion: This study revealed that fluid overload is closely associated with PHT. Intervention to reduce excess volume in this patient cohort can reduce pulmonary hypertension.
