Acute kidney injury recovery status predicts mortality and cardiorenal outcomes in patients admitted with acute decompensated heart failure.

ABSTRACT:

Background

Acute kidney injury (AKI) in the context of acute decompensated heart failure (ADHF) encompasses a broad spectrum of phenotypes with associated disparate outcomes. We evaluate the impact of 'ongoing AKI' on prognosis and cardiorenal outcomes and describe predictors of 'ongoing AKI'.

Methods

A prospective multicentre observational study of patients admitted with ADHF requiring intravenous furosemide was completed, with urinary angiotensinogen (uAGT) measured at baseline. AKI was defined using Kidney Disease Improving Global Outcomes (KDIGO) AKI criteria. AKI recovery status was defined as 'no AKI', 'recovered AKI' or 'ongoing AKI' based on renal function at hospital discharge. Event-free survival analysis was performed to predict death and cardiorenal outcomes at h
