Abstract

Background: Worsening renal function (WRF) during acute heart failure (AHF) occurs frequently and has been associated with adverse outcomes, though this association has been questioned. WRF is now evaluated by function and injury. We evaluated whether urine neutrophil gelatinase-associated lipocalin (uNGAL) is superior to creatinine for prediction and prognosis of WRF in patients with AHF.

Methods and Results: We performed a multicenter, international, prospective cohort of patients with AHF requiring IV diuretics. The primary outcome was whether uNGAL predicted development of WRF, defined as a sustained increase in creatinine of 0.5 mg/dL or >= 50% above first value or initiation of renal replacement therapy, within the first 5 days. The main secondary outcome was a composite of in-hospital adverse events. We enrolled 927 patients (mean 68.5 years of age, 62% men). The primary outcome occurred in 72 patients (7.8%). The first, peak and the ratio of uNGAL to urine creatinine (area under curves (AUC)

Conclusions: uNGAL was not superior to creatinine for predicting WRF or adverse in-hospital outcomes and cannot be recommended for WRF in AHF.
