The purpose of this study is to investigate the relation between residual SYNTAX score (rSS) and contrast-induced nephropathy (CIN) development in patients with non-ST segment elevation myocardial infarction (NSTEMI) with normal or near-to-normal left ventricular ejection fraction (LVEF) who underwent percutaneous coronary intervention (PCI). A total of 306 patients who underwent PCI with NSTEMI were included in our study. SYNTAX scores were calculated for the periods before and after PCI. Patients were divided into 2 groups as developed CIN following PCI (CIN +) and patients did not (CIN -). Fifty-four (17.6%) of patients who were included in the study developed CIN. Age (P = .001) and rSS (P = .002) were significantly higher and LVEF was lower (P = .034) in the CIN (+) group. Age (P = .031, odds ratio [OR]: 1.031, 95% CI, 1.003-1.059) and rSS (P = .04, OR: 1.036, 95% CI, 1.002-1.071) were independent predictors for CIN. In receiver operating characteristic analyses, when the cutoff value of rSS was taken as 3.5, it determined CIN with 79% sensitivity and 65% specificity. Contrast-induced nephropathy may develop more frequently in patients with increased rSS value. The rSS may be useful to follow-up these patients for CIN development.
