The association of PRECISE-DAPT score with development of contrast-induced nephropathy in patients with ST-elevation myocardial infarction undergoing primary percutaneous coronary intervention

Given that parameters used in the calculation of the PRECISE-DAPT risk score are important contributors to contrast-induced nephropathy (CIN) development, we hypothesized that the PRECISE-DAPT risk score would show good accuracy for predicting CIN in patients with ST-elevation myocardial infarction (STEMI) undergoing primary percutaneous coronary intervention (PCI). Therefore, in this study, we aimed to determine the predictive value of the admission PRECISE-DAPT score for the occurrence of CIN in patients with STEMI treated with primary PCI. After evaluation regarding with exclusion criteria, 1280 patients were, respectively, enrolled in the study. The primary end-point was the incidence of CIN. The PRECISE-DAPT score of CIN group was higher than the non-CIN group [31 (24-41) vs. 14 (9-23), p<0.001, respectively]. In multivariate logistic regression analysis, PRECISE-DAPT score was independently associated with the development of CIN [odds ratio (OR) 1.090, 95% confidence interval (CI) 1.066-1.114, p<0.001]. A receiver-operating characteristic (ROC) analysis was drawn to show the best cut-off value of the PRECISE-DAPT score to predict CIN was21 with 81.3% sensitivity and 72.7% specificity [area under curve (AUC): 0.834; 95% CI 0.812-0.854; p=0.017]. The PRECISE-DAPT score may be a significant independent predictor of CIN in patients with STEMI treated with primary PCI. Therefore, follow-up of patients with higher PRECISE-DAPT score should be performed more cautiously, and it should be noted that the development of CIN risk of these patients group is high.
