© 2020 Sociedade Portuguesa de CardiologiaBackground: Contrast-induced nephropathy (CIN) is a life-threatening complication after primary percutaneous coronary intervention (p-PCI). Oxidative stress and inflammation may play an important role in the development of CIN. Objective: We aimed to assess the relationship between total oxidant status, total antioxidant capacity, high-sensitivity C-reactive protein (hs-CRP), gamma-glutamyltransferase and uric acid (UA) in the development of CIN in patients presenting with ST-elevation myocardial infarction (STEMI). Methods: This prospective cohort study consisted of 341 patients with STEMI. Patients were divided into two groups: those with and those without CIN. Predictors of CIN were determined by multivariate regression analyses. Results: Multivariate regression analysis showed that initial glucose level, contrast media volume/glomerular filtration ratio (eGFR) ratio, hs-CRP, UA and oxidative status index were associated with the development of CIN in patients with STEMI. Conclusion: The main finding of this study is that increased oxidative stress and inflammation parameters were associated with the development of CIN in patients with STEMI. Other independent predictors of CIN were contrast media volume/eGFR ratio, initial glucose level, UA and hs-CRP. |
