摘要
The aim of this study was to investigate the relationship between lymphocyte to monocyte ratio (LMR) and the severity of coronary artery disease (CAD) by using Gensini score. A total of 199 patients, who had undergone coronary angiography, were included in the study and retrospectively analyzed. Among them, 49 patients who had normal coronary arteries were selected as the control group. Patients with CAD were divided into 2 groups, those with low Gensini score (<= 40) and those with high Gensini score (>= 40). Our results showed that LMR in the severe atherosclerosis group was significantly lower than those of the mild atherosclerosis group and the control group. There was a closely significant correlation between the Gensini score and LMR (r= -0.362, P < .001). Furthermore, multivariate logistic regression analysis demonstrated that LMR (odds ratio, 0.715; 95% confidence interval [CI], 0.551-0.927; P = .012) was independent predictors of severe atherosclerosis. Using an optimal LMR cut-off value of 5.06, LMR predicted severe atherosclerosis with a sensitivity of 57.1% and specificity of 69.7% (area under curve = 0.634; 95% CI, 0.545-0.724; P = .005). Then patients with CAD group was divided into 2 groups according to the LMR value of 5.06. Patients with LMR <= 5.06 had worse prognosis, with a higher rate of cardiovascular events during up to 1 year follow-up. Our study demonstrated that LMR was independently and positively associated with the severity of coronary atherosclerosis, providing a new insight in the application of inflammation index evaluating the severity of CAD. And LMR may be a useful predictor of future cardiovascular events in patients with CAD.
