BACKGROUND: In patients with end-stage renal disease (ESRD), pulmonary hypertension (PH) is a frequent complication with different etiologies and a 17 - 56 % prevalence rate. We evaluated the impact of fluid retention measured by bioimpedance on the prevalence of PH in this patient cohort.
METHODS: All patients with ESRD at the dialysis center of the Medical Clinic II of the University Hospital Gießen were invited to participate in the study and undergo non-invasive PH screening. If the screening suggested PH, patients underwent bioimpedance spectroscopy for measurement of fluid retention followed by adjustment of fluid levels to normovolemia as far as possible. Thereafter a second non-invasive screening was performed in this patient cohort after reaching normovolemia. If signs for PH persisted, patients underwent right heart catheterization for further assessment.
RESULTS: 52 patients agreed to participate in the study. After the first noninvasive screening, PH was suspected in 12 patients (23 %). After adjustment of fluid levels to reach normovolemia, PH was suspected only in 4 patients (7.7 %) with confirmation in 2 patients by right heart catheterization (3.8 %).
DISCUSSION: In patients with ESRD, PH is frequently associated with fluid retention as shown by bioimpedance spectroscopy. After adjustment of fluid to normal levels, PH was confirmed by invasive test in nearly 4 % of cases.
