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 analysis showed that high TyG index was associated with increased risk of CAD〔OR=1.385, 95%CI (1.123, 1.707) , P<0.01〕 and obstructive CAD〔OR=1.255, 95%CI (1.034, 1.523) , P<0.05〕.

Conclusion

TyG index was correlated with coronary atherosclerosis, and its increase was associated with enhanced risk of CAD and obstructive CAD, but had no correlation with carotid atherosclerosis. The relationship between TyG index and carotid atherosclerosis still needs to be confirmed by prospective studies.
