Incidence, Risk Factors and Prognosis of Contrast-Induced Acute Kidney Injury in Acute Heart Failure Patients Undergoing Coronary Angiography.

ABSTRACT:

Background and objectives

Heart failure (HF) is a well-known risk factor for contrast-induced acute kidney injury (CI-AKI). We sought to evaluate the risk factors and prognostic impact of CI-AKI in patients with AHF who undergo coronary angiography (CAG).

Methods

A total 594 patients with AHF underwent CAG from May 1, 2011 to December 31, 2013. CI-AKI was defined as an increase ≥25% or ≥0.5 mg/dL in serum creatinine at 48 hours after CAG or the initiation of dialysis after CAG. The deviation of body weight on CAG day from the dry weight (ΔBWT_CAG, %) was calculated for each patient.

Results

Overall, CI-AKI was observed in 24.7% of patients. Patients with CI-AKI had higher in-hospital death (16.3% vs. 5.1%, p<0.001; relative risk [RR], 2.50; 95% confidence in
