Association of lymphocyte to monocyte ratio with severity of coronary artery disease

Abstract

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
