【摘要】 背景 胰岛素抵抗(IR)与动脉粥样硬化(AS)相关,三酰甘油葡萄糖(TyG)指数是评估 IR 较好
的指标,目前 TyG 指数与症状性冠状动脉粥样硬化性心脏病(CAD)的相关性研究较少,同时老年人群中 TyG 指数与
颈动脉 AS 关系尚不明确。目的 分析 TyG 指数与冠状动脉及颈动脉 AS 程度的相关性,评估其评价大动脉 AS 的应用
价值。方法 本研究为单中心回顾性研究,纳入 2018 年 1 月至 2021 年 1 月兰州大学第二医院疑诊为 CAD 的住院患
者,通过电子病例系统获取一般临床资料及颈动脉超声、冠状动脉造影结果,计算 TyG 指数、Framingham 风险评分、
Gensini 评分。结果 该研究共纳入 1 232 例受试者,依据 TyG 指数平均值将受试者分为低值组(<9.05,n=616)和高
值组(≥ 9.05,n=616)。TyG 指数及 TyG 指数分组与 Framingham 风险评分、CAD、阻塞性 CAD、Gensini 评分均呈
正相关(P<0.01),而与颈动脉斑块、平均颈动脉内膜中层厚度(IMT)、颈动脉斑块评分(cPS)无相关关系(P>0.05);
CAD 及阻塞性 CAD 与颈动脉斑块、平均 IMT、cPS、Framingham 风险评分呈正相关(P<0.001)。二元 Logistic 回归分
析结果显示,TyG 指数是 CAD〔OR=1.385,95%CI(1.123,1.707),P<0.01〕及阻塞性 CAD〔OR=1.255,95%CI(1.034,
1.523),P<0.05〕发生的影响因素。结论 TyG 指数可能与经冠状动脉造影检查证实的冠状动脉 AS 病变程度相关,
是 CAD、阻塞性 CAD 的影响因素,而 TyG 指数与颈动脉 AS 无相关性,其与颈动脉 AS 的因果关系尚需前瞻性研究进
一步证实。

【Abstract】 Background Triglyceride-glucose (TyG) index is a relatively good predictor of insulin resistance,
an indicator that is associated with atherosclerosis. There are few studies on the correlation between TyG index and symptomatic
coronary artery disease (CAD). And there is no evidence definitely determining the relationship between TyG index and carotid
atherosclerosis in the elderly. Objective To perform an analysis of the relationship of TyG index with coronary and carotid
atherosclerosis,to assess its predictive value for large artery atherosclerosis. Methods A single-center retrospective design was
used. Inpatients with suspected CAD in Lanzhou University Second Hospital were enrolled from January 2018 to January 2021.
General clinical characteristics,carotid ultrasonography and coronary angiography results obtained from the electronic hospital
information system,as well as calculated TyG index,Framingham Risk score,and Gensini score were collected. Results A
total of 1 232 cases were enrolled. Correlation analysis showed that the Framingham Risk score,risk of CAD,obstructive CAD,
and Gensini score increased with the growth of TyG index value(P<0.01) either in high TyG index(mean value ≥ 9.05,
n=616) or low TyG index(mean value <9.05,n=616) group of patients,but had no association with carotid atherosclerosis,
mean intimal media thickness(IMT) and carotid plaque score(cPS)(P>0.05);CAD and obstructive CAD were positively
correlated with carotid atherosclerosis,mean IMT,cPS and Framingham risk score(P<0.001). Binary Logistic regression
