Background: The incidence, risk factors, and outcome of contrast-induced acute kidney injury (CI-AKI) in 730 patients with acute coronary syndrome (ACS) undergoing emergency percutaneous coronary intervention (PCI), whose contrast volume was below maximum allowable contrast dose (MACD) was prospectively investigated. Methods and Results: MACD was defined as (5 ml×body weight [kg]/baseline creatinine [mg/dl]). CI-AKI was defined as a greater than 25% increase in creatinine from the baseline or an absolute increase of ≥0.5 mg/dl within 48 h after the procedure. CI-AKI occurred in 212 (29%) patients. Patients with CI-AKI had a higher risk for in-hospital mortality (9.4% vs. 1.5%, P<0.001) and a longer stay in the coronary care unit (median, 4.0 vs. 3.0 days, P<0.001) compared with those without CI-AKI. In a multivariate logistic analysis including 20 clinical variables, elevated glucose levels as variables categorized into quartiles were independently (P<0.001) associated with the development of CI-AKI. In addition, this relationship was seen in both the subgroup of patients with known diabetes and that of those without known diabetes. Conclusions: CI-AKI might occur commonly and could be be associated with a more complicated clinical course in ACS patients undergoing emergency PCI whose contrast volume does not exceed MACD. Elevated pre-procedural glucose might be a powerful and independent risk factor for the development of CI-AKI in this population.
