Neutrophil-to-HDL-C Ratio as an inflammatory biomarker in patients with anxiety and obstructive coronary artery disease: A retrospective study

Background: Anxiety is a common comorbidity with coronary artery disease (CAD). The neutrophil-to-lymphocyte ratio (NLR), neutrophil-to-high-density lipoprotein cholesterol (HDL-C) ratio (NHR), lymphocyte-to-HDL-C ratio (LHR), and monocytes-to-lymphocyte ratio (MLR) can predict the severity of CAD. This retrospective study aimed to explore the relationship between NLR, NHR, LHR, and MLR and the presence of obstructive or severe CAD (OCAD, SCAD) in patients with comorbid anxiety and chest pain. Methods: A total of 1063 patients with anxiety and chest pain were divided into an NOCAD group and OCAD group according to computed topography angiography (CCTA). The 455 patients in the OCAD group were further divided into the NSCAD group (n = 216) and SCAD group (n = 239) according to coronary angiography (CAG) results, and the Gensini score (GS) was calculated. Demographic and laboratory data were collected. Results: Multiple regression analysis showed that higher NLR, NHR, and LHR served as independent risk factors for OCAD in patients with anxiety and chest pain (OR 1.37, 95%CI: 1.13–1.65, p = 0.001; OR 2.24, 95%CI: 1.89–2.65, p
