Relationship between Neutrophil-to-Lymphocyte Ratio and Plaque Components in Patients with Coronary Artery Disease: Virtual Histology Intravascular Ultrasound Analysis.

Relationship between Neutrophil-to-Lymphocyte Ratio and Plaque Components in Patients with Coronary Artery Disease: Virtual Histology Intravascular Ultrasound Analysis. J Korean Med Sci. 2014 Jul;29(7):950-6 Authors: Choi YH, Hong YJ, Ahn Y, Park IH, Jeong MH Abstract The aim of this study was to evaluate the relation between neutrophil-to-lymphocyte ratio (NLR) and plaque components assessed by virtual histology-intravascular ultrasound in 399 coronary artery disease (CAD) patients with 471 coronary lesions. We classified the lesions into two groups according to the NLR on admission {low NLR group (NLR≤2.73 [n=370]) vs. high NLR group (NLR>2.73 [n=101])}. By volumetric analysis, total atheroma and the absolute necrotic core (NC) volumes were significantly greater in high NLR group (249.9±149.7 µL vs. 192.5±127.7 µL, P=0.001, and 32.7±26.8 µL vs. 22.8±19.4 µL, P=0.001, respectively) and thin-cap fibroatheroma (TCFA) was observed more frequently in high NLR group (33% vs. 18%, P=0.001). ST segment elevation myocardial infarction (odds ratio [OR], 2.159; 95% CI, 1.000-4.660, P=0.050) and NLR>2.73 (OR, 1.848; 95% CI, 1.016-3.360, P=0.044) and total atheroma volume (OR, 1.003; 95% CI, 1.001-1.004, P=0.004) were the independent predictors of TCFA. CAD patients with high NLR had more vulnerable plaque components (greater NC-containing plaques) than those with low NLR. PMID: 25045227 [PubMed - in process]
