摘要
Background： Previous studies of contrast-induced acute kidney injury （CI-AK1） were mostly based on selective percutaneous coronary intervention （PCI） cases, and risk factors of CI-AKI after emergency PCI are unclear. The aim of this study was to explore the risk factors of CI-AKi in a Chinese population undergoing emergency PCI. Methods： A total of 1061 consecutive patients undergoing emergency PCI during January 2013 and June 2015 were enrolled and divided into CI-AK1 and non-CI-AKl group. Univariable and multivariable analyses were used to identity the risk factors of CI-AKI in emergency PCI patients. CI-AKI was defined as an increase in serum creatinine ≥25% or ≥0.5 mg/dl （44.2 μmol/L） above baseline within 3 days alter exposure to contrast medium. Results： The incidence of C1-AKI in patients undergoing emergency PCI was 22.7% （241/1061）. Logistic multivariable analysis showed that body surface area （BSA） （odds ratio [OR] 0.213, 95% confidence interval [CI]： 0.075-0.607, P = 0.004）, history, of myocardial infarction （MI） （OR 1.642, 95% CI. 1.079-2.499, P- 0.021 ）, left ventricular ejection fraction （LVEF） （OR 0.969, 95% CI： 0.944-0.994, P = 0.015）, hemoglobin （Hb） （OR 0.988, 95% CI. 0.976-1.000, P 1.018 1.037, P 〈 0.001 ）, left anterior descending （LAD） stented （OR 1 0.009 0.987, P- 0.049）, and diuretics use （OR 1.850, 95% CI： 1.233-2 0.045）, estimated glomerular filtration rate （OR 1.027, 95% CI： 464, 95% CI： 1.000 2.145, P 0.050）, aspirin （OR 0.097, 95%CI： .777, P - 0.003） were independent predictors of CI-AKI in patients undergoing emergency PCI. Conclusion： History of MI, low BSA, LVEF and Hb level, LAD stented, and diuretics use are associated with increased risk of CI-AK1 in patients undergoing emergency PCI.
