Risk prediction of contrast-induced nephropathy by ACEF score in patients undergoing coronary catheterization.

AimsTo explore the ability of the ACEF score to predict the incidence of contrast-induced nephropathy (CIN) in patients undergoing coronary angiography with or without percutaneous coronary intervention.MethodsA total of 706 patients undergoing coronary angiographypercutaneous coronary intervention (PCI) between March 2011 and October 2011 were analyzed. CIN using different definitions was termed as CINnarrow (rise in serum creatinine 0.5mg/dl) and CINbroad (rise in serum creatinine 0.5mg/dl and/or 25% increase in baseline serum creatinine).ResultsThe mean ACEF score was 1.5 +/- 0.6. Overall incidences of CINnarrow and CINbroad were 5.5% and 13.6%, respectively. There was a significant gradient in the incidence of CINnarrow (2.9%, 3.9%, 10.6% in the I, II, and III tertiles, respectively, P<0.001) and CINbroad (9.1%, 14.2%, 17.9% in the I, II, and III tertiles, respectively, P=0.021) across increasing ACEF tertiles. The ACEF score was independently associated with the risk of CINnarrow (adjusted odds ratio [OR] 1.6, 95% confidence interval [CI] 1.0-2.7; P=0.047). Discrimination was more satisfactory when using the ACEF as a predictor of CINnarrow (c-statistic 0.71, 95% 0.63-0.79).ConclusionThe ACEF score is an independent and potentially useful predictor of CIN defined as rise in serum creatinine 0.5mg/dl.
