Aim: Contrast-induced nephropathy (CIN) is responsible for an increased mortality rate and correlates with increases in hospital stays and the risk of cardiovascular complications. The platelet to lymphocyte ratio (PLR) was introduced as a potential marker to determine the balance between thrombosis and inflammation and was associated with increased cardiovascular morbidity and mortality. We investigated whether PLR on admission is an independent risk factor that predicts the development of CIN in patients with ST-segment elevation myocardial infarction (STEMI) underwent primary percutaneous coronary intervention (pPCI). Material and Methods: 1348 consecutive patients with acute STMI who were admitted to our institution and underwent pPCI were retrospectively evaluated. Data obtained from hospital files and computer records. CIN development was accepted as the endpoint. Results: A total of 127 (9.4%) patients experienced CIN. 16 patients underwent renal replacement theraphy. In-hospital mortality rate was found 2.7% (n = 37). Patients were divided into two groups based on development of CIN. Age (P = 0.001), baseline GFR (P < 0.001), grade 3 and more chronic kidney disease (P < 0.001), baseline creatinin (P < 0.001), EF (P < 0.001), presence of DM (P < 0.001) were different between groups. In multivariate analyses, PLR (odds ratio [OR] 1.012, 95% confidence interval [CI] 1.006-1.017, P < 0.001) was independently predicted CIN development. Conclusion: PLR is easily available, widely used, and relatively cheap biomarker, and is an independent predictor of CIN development in patients with STEMI undergoing pPCI.
