Abstract

STUDY OBJECTIVES: To identify baseline predictors of worsening renal function (WRF) in an acute decompensated heart failure (ADHF) patient population receiving continuous infusion loop diuretics. DESIGN: Retrospective observational analysis. SETTING: Academic tertiary medical center. PATIENTS: A total of 177 patients with ADHF receiving continuous infusion loop diuretics from January 2006 through June 2009. MEASUREMENTS AND MAIN RESULTS: The mean patient age was 61 years, 63% were male, ~45% were classified as New York Heart Association functional class III, and the median length of loop diuretic infusion was 4 days. Forty-eight patients (27%) developed WRF, and 34 patients (19%) died during hospitalization. Cox regression time-to-event analysis was used to determine the time to WRF based on different demographic and clinical variables. Baseline serum albumin 3 g/dl or less was the only significant predictor of WRF (hazard ratio [HR] 2.87, 95% confidence interval [CI] 1.60-5.16, p=0.0004), which remained significant despite adjustments for other covariates. CONCLUSION: Serum albumin 3 g/dl or less is a practical baseline characteristic associated with the development of WRF in patients with ADHF receiving continuous infusion loop diuretics.
