Abstract

Objectives: We examined the ESCAPE (Evaluation Study of Congestive Heart Failure and Pulmonary Artery Catheterization Effectiveness) database to understand the impact and pathophysiology of renal dysfunction in patients hospitalized with advanced decompensated heart failure (HF). Background: Baseline renal insufficiency (RI) (estimated glomerular filtration rate [eGFR] <60 ml/min) and worsening renal function (WRF) (↑ serum creatinine [SCr] ≥0.3 mg/dl) during treatment of decompensated HF are associated with adverse outcomes. Methods: We used a Cox proportional hazards model to evaluate the impact of renal function on 6-month outcomes. Renal parameters were correlated with hemodynamic measurements. The impact of a strategy using pulmonary artery catheter (PAC) guidance on WRF and outcomes in patients with baseline RI was compared with treatment based on clinical assessment alone. Results: Baseline and discharge RI, but not WRF, were associated with an increased risk of death and death or rehospitalization. Among the hemodynamic parameters measured in patients randomized to the PAC arm (n = 194), only right atrial pressure correlated weakly with baseline SCr (r = 0.165, p = 0.03). There was no correlation between baseline hemodynamics or change in hemodynamics and WRF. A PAC-guided strategy was associated with less average increase in creatinine but did not decrease the incidence of defined WRF during hospitalization or affect renal function after discharge relative to clinical assessment alone. Conclusions: Among patients with advanced decompensated HF, baseline RI impacts outcomes more than WRF. Poor forward flow alone does not appear to account for the development of RI or WRF in these patients. The addition of hemodynamic monitoring to clinical assessment does not prevent WRF or improve renal function after discharge.
