中性粒细胞/高密度脂蛋白胆固醇比值与青年急性心肌梗死患者冠脉病变严重程度的相关性研究

Correlation Between Neutrophil/HDL-C Ratio and Severity of Coronary Artery Lesion in Young Adults with Acute Myocardial Infarction

目的 研究中性粒细胞/高密度脂蛋白胆固醇比值(NHR)与青年急性心肌梗死患者冠脉病变严重程度的相关性。方法 选取2019年6月至2023年6月于安徽医科大学第一附属医院住院的青年(年龄18~45岁)急性心肌梗死患者109例,根据Syntax评分分为Syntax低危组(n=85)和Syntax中高危组(n=24),以同时期冠状动脉造影阴性患者为阴性对照组(非冠心病组,n=52),收集一般临床资料及相关血清学指标,计算出NHR值,使用Pearson相关性分析及Logistics回归分析NHR与冠脉病变严重程度的相关性,并进一步进行亚组分析及交互性检验。受试者工作曲线(ROC)评价NHR在预测青年急性心肌梗死患者冠脉病变严重程度中的价值。结果 性别、吸烟率、饮酒率、糖尿病史、中性粒细胞绝对数、三酰甘油、高密度脂蛋白胆固醇(HDL-C)、NHR、极低密度脂蛋白胆固醇(VLDL-C)、载脂蛋白B(APOB)、空腹血糖、糖基化血红蛋白在三组间差异均有统计学意义(均P<0.05)。两两比较中,中性粒细胞绝对数、NHR在三组间差异均有统计学意义;体质量指数(BMI)在非冠心病组与Syntax中高危组间差异有统计学意义;HDL-C、空腹血糖、糖基化血红蛋白在Syntax低危组与非冠心病组及Syntax中高危组与非冠心病组间的差异有统计学意义(均P<0.05);肌酐、APOB在Syntax低危组与非冠心病组间差异有统计学意义;三酰甘油、脂蛋白(a)[LP(a)]、VLDL-C在Syntax低危组与Syntax中高危组间差异有统计学意义(均P<0.05)。Pearson相关性分析显示,NHR与Syntax评分呈正相关(r=0.322,P<0.01)。单因素及多因素二元Logistic回归分析显示NHR(OR=1.265,95%CI:1.097~1.458,P<0.05)是青年急性心肌梗死冠脉病变严重程度的独立危险因素。亚组分析显示,NHR在BMI≥24 kg/m^(2)、吸烟、饮酒人群中与冠脉病变严重程度均呈显著相关(均P<0.05),交互作用检验差异无统计学意义。ROC曲线显示,NHR预测青年急性心肌梗死冠脉病变严重程度曲线下面积(AUC)为0.758,截断值为7.0319,敏感度83.3%,特异度63.53%。结论 NHR在预测青年急性心肌梗死冠脉病变严重程度上有一定价值。

Objective To investigate the relationship between neutrophil/high-density lipoprotein cholesterol ratio(NHR)and the severity of coronary artery lesions in young adults with acute myocardial infarction.Methods A total of 1o9 young adults(aged 18~45 years)with acute myocardial infarction admitted to the First Affiliated Hospital of Anhui Medical University from June 2019 to June 2023 were selected and divided into Syntax low-risk group(n=85)and Syntax medium-high-risk group(n=24)according to Syntax score.Patients with negative coronary angiography during the same period were negative control group(n=52).General clinical data and related serum markers were collected,and NHR value was calculated.Pearson correlation analysis and logistics regression analysis were performed to examine the correlation between NHR and the severity of coronary artery lesions.Subgroup analysis and interaction testing were further conducted.The receiver operating curve(ROC)was performed to evaluate the value of NHR in predicting the severity of coronary artery lesions in young adults with acute myocardial infarction.Results Gender,smoking rate,alcohol consumption rate,diabetes history,absolute number of neutrophils,triglyceride,HDL-C,NHR,VLDL-C,apolipoprotein B(APOB),fasting blood glucose and glycosylated hemoglobin were significantly different among the three groups(P<o.05).In pairwise comparison,the absolute number of neutrophil and NHR were significantly different among the three groups.BMI was significant different between non-CHD group and Syntax medium-high-risk group.HDL-C,fasting blood glucose and glycosylated hemoglobin were significant different between Syntax low-risk group and non-CHD group,as well as between Syntax medium-high-risk group and non-CHD group(P<o.05).Creatinine and APOB were significant different between Syntax low-risk group and non-CHD group.Triglyceride,VLDL-C and LP(a)were significant different between Syntax low-risk group and Syntax medium-high-risk group(P<0.05).Pearson correlation analysis showed a positively correlation between NHR and Syntax score(r=0.322,P<0.01).Univariate and multivariate binary logistic regression analysis showed that NHR(OR-1.265,95%CI1.097~1.458,P<0.05)was an independent risk factor for the severity of coronary artery lesions in young adults with acute myocardial infarction.Subgroup analysis showed that NHR was significantly associated with the severity of coronary artery lesions in patients with BMI≥24 kg/m^(2),smokers,drinkers and non-drinkers(P<0.05).No significant difference was observed in interaction analysis.The ROC curve showed that the area under the curve(AUC)predicted by NHR for acute myocardial infarction in young adults was 0.758,with a cut-off value of 7.0319,sensitivity of 83.3%,and specificity of 63.53%.Conclusion NHR has a certain value in predicting the severity of coronary artery lesions in young adults with acute myocardial infarction.
