Abstract
Background
Neutrophil-to-lymphocyte ratio (NLR) is a marker of systemic inflammation that correlates with cardiac events. This study assessed the association between NLR and the presence of chronic coronary total occlusion (CTO).
Methods
The study population included 225 patients, a control group (n = 75), a coronary artery disease group (n = 75), and a CTO group (n = 75). NLR was compared in the three groups.
Results
NLR levels were significantly higher in the CTO than in the other two groups (p < 0.001). Bivariate correlation analysis showed a positive correlation between NLR and SYNTAX Score, and multivariate logistic regression analysis found that NLR was an independent predictor of CTO. ROC analysis showed that an NLR cut-off of 2.09 could distinguish between patients with and without CTO (AUC = 0.74; 95% CI, 0.68–0.81), with a specificity of 69.3% and a sensitivity of 61%.
Conclusion
NLR may be useful as a marker of CTO.
