Abstract

Background Patients with acute decompensated heart failure with diuretic resistance (ADHF-DR) have a poor prognosis. The aim of this study was to assess in patients with ADHF-DR, whether haemodynamic changes during ultrafiltration (UF) are associated with changes in renal function (Δcreatinine) and whether Δcreatinine post UF is associated with mortality. Methods Seventeen patients with ADHF-DR underwent 20 treatments with UF. Serial bloods (4–6 hourly) from the onset of UF treatment were measured for renal function, electrolytes and central venous saturation (CVO2). Univariate and multivariate analysis were performed to assess the relationship between changes in markers of haemodynamics [heart rate (HR), systolic blood pressure (SBP), packed cell volume (PCV) and CVO2] and Δcreatinine. Patients were followed up and mortality recorded. Cox-regression survival analysis was performed to determine covariates associated with mortality. Results Renal function worsened after UF in 17 of the 20 UF treatments (baseline vs. post UF creatinine: 164 ± 58 vs. 185 ± 69 μmol/l, P 2 was significantly associated with Δcreatinine [β-coefficient of − 1.3 95%CI (− 1.8 to − 0.7), P
