Our aim in this study is to investigate the relationship between the TyG index and CIN in non-diabetic non-ST elevation acute myocardial infarction (NSTEMI) patients. The study included 272 non-diabetic patients who applied with NSTEMI and underwent coronary angiography (CAG). Patient data were divided into quartiles according to the TyG index: Q1: TyG?<?8.55; Q2: 8.55???TyG???8.87; Q3: 8.88???TyG???9.29; and Q4: TyG?>?9.29. Baseline characteristics, laboratory measurements, angiography data, and the incidence of CIN were compared between the groups. CIN was observed in 18 (6.6%) patients in the study. The incidence of CIN was lowest in the Q1 group and highest in the Q4 group (1 (1.5%) in Q1; 3 (4.4%) in Q2; 5 (7.4%) in Q3; 9 (13.2%) in Q4; p?=?0.040). TyG index was found to be an independent risk factor for the development of CIN in multivariate logistic regression analysis (odds ratio?=?6.58; confidence interval (CI)?=?2.12–20.40; p?=?0.001). TyG index value of 9.17 was identified as an effective cut-off point for the prediction of CIN (Area under the curve: 0.712, CI: 0.590–0.834, p?=?0.003), and it had a sensitivity of 61% and a specificity of 72%. The results of this study showed that a high TyG index increases the incidence of CIN after CAG in non-diabetic NSTEMI patients and is an independent risk factor for the development of CIN.eninfo:eu-repo/semantics/closedAccessContrast-induced NephropathyInsulin ResistanceNon-ST Elevation Acute Myocardial InfarctionTriglyceride-glucose IndexArticle71883884410.1177/1081558923118231737377036Q2WOS:001098990000007Q1
