A comparison between different definitions of contrast-induced acute kidney injury for long-term mortality in patients with acute myocardial infarction.

ABSTRACT:

Background

Few studies have demonstrated the association between contrast-induced acute kidney injury (CI-AKI) and long-term mortality and explored which definition of CI-AKI accounts for most long-term deaths among patients with acute myocardial infarction (AMI). Therefore, we aimed to evaluate this association and compared the population attributable risks (PARs) of three CI-AKI definitions.

Methods

We analyzed 1300 consecutive AMI patients undergoing angiography in Guangdong Provincial People's Hospital. The endpoint was all-cause mortality. CI-AKI was evaluated according to three definitions: (1) CI-AKI_A, with a serum creatinine elevation ≥ 50% or ≥ 0.3 mg/dL from baseline in the first 72 h after procedure; (2) CI-AKI_B, ≥ 0.5 mg/dL in 72 h; (3) CI-A
