摘要:

目的 探讨中性粒细胞/淋巴细胞比值(neutrophil-lymphocyte ratio, NLR)、血小板/淋巴细胞比值(platelet-lymphocyte ratio, PLR)及单核细胞/淋巴细胞比值(monocyte-lymphocyte ratio, MLR)与2型糖尿病(diabetes mellitus type2, T2DM)合并冠心病(coronary heart disease, CHD)患者冠状动脉病变严重程度的相关性。方法 收集2019年1月至2021年12月于威海市中心医院住院并行冠状动脉造影检查的T2DM患者517例,根据冠状动脉造影结果分为单纯T2DM组161例和T2DM合并CHD组356例,比较两组一般资料及实验室检查指标。依据冠状动脉造影结果,计算出Gensini积分,将T2DM合并CHD组分为低危亚组(Gensini积分<16)151例、中危亚组(16≤Gensini积分<40)97例及高危亚组(Gensini积分≥40)108例,比较各亚组一般资料及实验室检查指标,Spearman相关性分析评估NLR、PLR、MLR与患者Gensini积分的相关性,采用logistic回归分析探讨T2DM合并CHD患者冠状动脉病变严重程度的影响因素。结果 T2DM合并CHD组与单纯T2DM组性别构成比、年龄、低密度脂蛋白、低密度脂蛋白/高密度脂蛋白、糖化血红蛋白、尿素氮、肌酐、胱抑素及NLR、PLR、MLR水平差异均有统计学意义( P<0.05)。高危亚组年龄、胱抑素及NLR、PLR、MLR水平显著高于低危亚组和中危亚组,差异有统计学意义( P<0.05)。Spearman相关性分析显示,NLR、PLR、MLR与患者Gensini积分呈正相关( r s=0.393, P<0.01; r s=0.322, P<0.01; r s=0.360, P<0.01)。有序多分类logistic回归分析提示年龄、性别、舒张压、身体质量指数、肌酐以及NLR、PLR是T2DM合并CHD患者冠状动脉病变严重程度的独立影响因素( P<0.05)。结论 NLR、PLR、MLR与T2DM合并CHD患者的Gensini积分呈正相关,NLR、PLR可作为T2DM合并CHD患者冠脉病变严重程度的独立预测因子。监测NLR、PLR有利于早期识别T2DM合并CHD患者冠脉病变的严重程度,预防急性冠脉综合征事件发生。

Abstract:

Objective To investigate the correlation of neutrophil-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR) and monocyte-lymphocyte ratio (MLR) with the severity of coronary artery disease in patients with type 2 diabetes mellitus (T2DM) complicated with coronary heart disease (CHD). Methods A total of 517 T2DM patients who underwent coronary angiography (CAG) in Weihai Central Hospital from January 2019 to December 2021 were divided into T2DM group ( n=161) and T2DM + CHD group ( n=356) according to the CAG findings of CHD or not. The general data and laboratory examination indexes of the two groups were compared. According to the results of CAG, Gensini scores were calculated. Patients in T2DM+CHD group were further divided into low-risk subgroup (Gensini score<16, n=151), medium-risk subgroup (16≤Gensini score <40, n=97) and high-risk subgroup (Gensini score≥40, n=108). The general data and laboratory examination indexes of patients in each subgroup were compared. Spearman correlation analysis was used to evaluate the correlation of NLR, PLR and MLR with the Gensini scores. Logistic regression analysis was used to explore the risk factors for the severity of coronary artery disease in T2DM patients complicated with CHD. Results There were significant differences in sex constituent ratio, age, low density lipoprotein (LDL), LDL/high density lipoprotein (HDL), glycosylated hemoglobin (HbA1c), urea nitrogen, creatinine, cystatin, NLR, PLR and MLR between T2DM group and T2DM+CHD group. The levels of age, cystatin, NLR, PLR and MLR in the high-risk subgroup were significantly higher in those of the low-risk and medium-risk subgroups ( P<0.05). Spearman correlation analysis showed that NLR, PLR and MLR were positively correlated with the Gensini scores ( r s=0.393, P<0.01; r s=0.322, P<0.01; r s=0.360, P<0.01). Ordered multivariate logistic regression analysis showed that age, sex, diastolic blood pressure, body mass index, creatinine, NLR and PLR were independent factors for the severity of coronary artery disease in T2DM patients complicated with CHD ( P<0.05). Conclusion NLR, PLR and MLR are positively correlated with the Gensini score of T2DM patients complicated with CHD. NLR and PLR can be used as independent predictors of the severity of coronary artery disease in them. Monitoring NLR and PLR is helpful to early identify the severity of coronary artery disease in T2DM patients complicated with CHD and prevent the occurrence of acute coronary syndrome.
