Prediabetes (preD) carries increased risk of cardiovascular (CV) events than normal-glucose-tolerance (NGT). Insulin resistance, a hallmark of preD, is closely linked to CV-risk, making its assessment crucial. Triglycerides-to-high-density-lipoprotein-cholesterol-ratio (TG/HDL) and triglycerides-and-glucose-product (TyG) have emerged as surrogate of insulin resistance. We aimed to evaluate the association of these indexes with CV-risk assessed through arterial stiffness in preD.
377 individuals without diagnosis of diabetes underwent: (1) complete biochemistry and oral-glucose-tolerance-test; (2) CV-risk assessment through arterial stiffness (pulsed-wave-velocity - PWV - and augmentation-index - AugI) and intima-media-thickness (IMT). Participants were split according to current guidelines: NGT (n = 100), preD (n = 216), and newly-diagnosed-type-2-diabetes (ND-T2D) (n = 61).
TG/HDL and TyG were higher in preD than NGT, with no difference between preD and ND-T2D regarding TG/HDL. PreD showed higher PWV, AugI, and IMT than NGT. In preD group, after adjusting for major confounders, PWV was correlated with TG/HDL (β = 0.16; P = 0.03), but not with TyG, and there was a trend of association with HOMA-IR (β = 0.19, P = 0.07). In logistic regression, being in the higher tertile of TG/HDL was associated with higher PWV (odds-ratio 2.51, 95 %CI 1.01-6.29, P = 0.048).
In preD, TG/HDL was independently associated with PWV, suggesting its possible role as a simple, cost-effective tool for assessing CV risk.
与糖耐量正常(NGT)相比,糖尿病前期(preD)发生心血管(CV)事件的风险更高。胰岛素抵抗是糖尿病前期的一个标志,与心血管风险密切相关,因此对其进行评估至关重要。甘油三酯与高密度脂蛋白胆固醇比值(TG/HDL)和甘油三酯与葡萄糖乘积(TyG)已成为胰岛素抵抗的替代指标。我们旨在评估这些指标与通过动脉僵硬度评估的糖尿病前期CV风险之间的关联。
377名未诊断出糖尿病的个体接受了:(1)完整的生化检查和口服葡萄糖耐量试验;(2)通过动脉僵硬度(脉搏波速度 - PWV - 和增强指数 - AugI)以及内膜中层厚度(IMT)进行CV风险评估。参与者根据现行指南进行分组:NGT(n = 100)、preD(n = 216)和新诊断的2型糖尿病(ND-T2D)(n = 61)。
糖尿病前期的TG/HDL和TyG高于NGT,糖尿病前期与新诊断的2型糖尿病在TG/HDL方面无差异。糖尿病前期的PWV、AugI和IMT高于NGT。在糖尿病前期组,在调整主要混杂因素后,PWV与TG/HDL相关(β = 0.16;P = 0.03),但与TyG无关,并且与稳态模型评估的胰岛素抵抗(HOMA-IR)存在关联趋势(β = 0.19,P = 0.07)。在逻辑回归中,处于TG/HDL较高三分位数与较高的PWV相关(优势比2.51,95%CI 1.01 - 6.29,P = 0.048)。
在糖尿病前期,TG/HDL与PWV独立相关,表明其可能作为一种简单、经济有效的工具用于评估CV风险。
