Abstract:

Objective To investigate the correlation of monocyte-to-lymphocyte ratio(MLR) with coronary heart disease(CHD) and the extent of coronary atherosclerosis. Methods A total of 200 CHD patients with positive coronary angiography results(major vessel diameter ≥50%) in North Branch of Ruijin Hospital of Shanghai Jiao Tong University School of Medicine from June to December 2022 were enrolled as CHD group,and 131 patients with negative coronary angiography results during the same period were enrolled as control group. The difference of MLR,neutrophil-to-lymphocyte ratio(NLR) and platelet-to-lymphocyte ratio(PLR) was evaluated between CHD and control groups. The correlations between MLR and creatine kinase(CK),lactate dehydrogenase(LDH) and Gensini scores were evaluated by Pearson or Spearman correlation analysis. Logistic regression analysis was used to evaluate the influencing factors of CHD. Receiver operating characteristic(ROC) curve was used to evaluate the efficacy of MLR in diagnosing CHD. Results MLR,NLR and PLR in CHD group were higher than those in control group(P<0.001). There was no statistical significance in MLR between CHD group and control group after therapy(P>0.05). MLR was positively correlated with CK,LDH and Gensini scores in CHD patients(r values were 0.150 0,0.290 0 and 0.545 1,P<0.05). CK,MLR,NLR and PLR were all influencing factors of CHD. After adjusting for confounding factors,the risk of CHD was 1.6 times higher when MLR>0.25 than when MLR≤0.17 [odds ratio(OR)=1.609,95% confidence interval(CI) 1.213-2.133]. The area under curve of MLR for diagnosing CHD was 0.674 3,the sensitivity was 62.00%,and the specificity was 62.60%. Conclusions MLR is related with CHD and the extent of coronary atherosclerosis,and it may be an independent predictor of the extent of coronary atherosclerosis in CHD patients,which can help clinical judgement whether to proceed with further invasive treatment.
