Guillon B, et al. - In patients admitted for acute coronary syndrome (ACS), researchers evaluated the incidence, predictors and impact on 6-month mortality of contrast-induced acute kidney injury (CI-AKI) after coronary angiography with or without percutaneous coronary intervention (PCI), according to 3 different CI-AKI definitions. Findings revealed that according to the definition used for CI-AKI, CI-AKI was observed in 6 to 15.7%. High-risk patients could not be detected by an increase of 25% over baseline serum creatinine (sCr). Detection of 15.7% of the population at twofold higher risk of mortality could be done with the use of CI-AKI defined as an increase in sCr >0.3mg/dL.
