The platelet to lymphocyte ratio (PLR) has been investigated as a new predictor for cardiovascular risk. The aim of the present study was to investigate the prognostic role admission PLRat admission in predicting in-hospital and early mortality in patients presenting with ST segment elevation myocardial infarction (STEMI). A total of 639 consecutive patients with STEMI who underwent primary percutaneous coronary intervention (PCI) were included. The study population was divided into tertiles on the basis of PLR values at the admission. A high PLR (N = 213) was defined as a value in the upper third tertile (PLR >174.9) and a low PLR (N = 426) was defined as any value in the lower two tertiles (PLR ≤ 174.9). The patients were followed for clinical outcomes for up to 6 months after discharge. In Kaplan-Meier survival analysis, the rate of 6-month all-cause deaths was 7% in the high PLR group versus 3% in the low PLR group (P = 0.03). In multivariate analyses, a significant association was noted between high PLR levels and the adjusted risk of 6-month all-cause deaths (odds ratio = 2.51, 95% confidence interval = 1.058-5.95; P = 0.03). PLR is a readily available clinical laboratory value associated with 6-month all-cause death in patients with STEMI who undergo primary PCI.
Galectin-3 is a novel, promising biomarker that may help identify type 2 diabetic patients who may require early CAD intervention because of the potential risk of coronary atherosclerosis.
We hypothesized that contrast media volume-estimated glomerular filtration rate (CV-e-GFR) ratio may be a predictor of contrast media-induced acute kidney injury (CI-AKI). We investigated the associations between CV-e-GFR ratio and CI-AKI in 597 patients undergoing primary percutaneous coronary intervention (pPCI). An absolute ≥0.3 mg/dL increase in serum creatinine compared with baseline levels within 48 hours after the procedure was considered as CI-AKI; 78 (13.1%) of the 597 patients experienced CI-AKI. The amount of contrast during procedure was higher in the CI-AKI group than in those without CI-AKI (153 vs 135 mL, P = .003). The CV-e-GFR ratio was significantly higher in patients with CI-AKI than without (2.3 vs 1.5, P < .001). In multivariate analysis, independent predictors of CI-AKI were low left ventricular ejection fraction (P = .018, odds ratio [OR] = 0.966), e-GFR <60 mL/min (P = .012, OR = 2.558), and CV-e-GFR >2 (P < .001, OR = 5.917). In conclusion, CV-e-GFR ratio is significantly associated with CI-AKI after pPCI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
