Abstract

Background: Type 2 diabetes mellitus (T2DM) is a primary contributor to coronary artery disease (CAD). Insulin resistance (IR) is a hallmark of T2DM and a significant risk factor for the progression of CAD. The triglyceride-glucose (TyG) index is a new alternative indicator to identify IR. We aimed to explore the association between the TyG index and severity of CAD in patients with T2DM.

Methods: 280 inpatients with T2DM were enrolled from November 2019 to November 2022, classified into the CAD group (n = 175) and non-CAD group (n = 105). The TyG index and SYNTAX score were calculated. According to SYNTAX score, patients were further classified into the mid-CAD group (n = 97) and moderate to severe CAD group (n = 78).

Results: A significant positive correlation between the TyG index and SYNTAX score was found in the CAD group (r = 0.70, p < 0.01). The TyG index predicted the presence of moderate to severe CAD significantly, and the area under the ROC curve was 0.79 (95% CI: 0.71-0.85, p < 0.01). The higher LDL-C and TyG index, the higher risk of developing moderate to severe CAD (OR = 4.40, 95% CI 1.28 - 15.16, p = 0.02; OR = 9.00, 95% CI 3.69 - 21.96, p < 0.01).

Conclusions: There was a significantly positive correlation between the TyG index and SYNTAX score in T2DM patients who developed CAD; the TyG index could predict a mid/high SYNTAX score (≥ 23) and increase the risk of moderate to severe CAD.

2 型糖尿病合并冠状动脉疾病患者的甘油三酯-葡萄糖指数与冠状动脉疾病严重程度之间的关系：一项回顾性研究。

背景：2 型糖尿病（T2DM）是冠状动脉疾病（CAD）的主要诱因。胰岛素抵抗（IR）是 T2DM 的标志，也是导致冠状动脉疾病恶化的重要风险因素。甘油三酯-葡萄糖（TyG）指数是识别 IR 的一个新的替代指标。我们旨在探讨TyG指数与T2DM患者CAD严重程度之间的关联。方法：从2019年11月至2022年11月，我们招募了280名T2DM住院患者，分为CAD组（n = 175）和非CAD组（n = 105）。计算TyG指数和SYNTAX评分。根据SYNTAX评分，患者被进一步分为中度CAD组（n = 97）和中重度CAD组（n = 78）：结果：在 CAD 组中，TyG 指数与 SYNTAX 评分之间存在明显的正相关性（r = 0.70，p p = 0.02；OR = 9.00，95% CI 3.69 - 21.96，p 结论：TyG 指数与 SYNTAX 评分之间存在明显的正相关性：在患有 CAD 的 T2DM 患者中，TyG 指数与 SYNTAX 评分之间存在明显的正相关；TyG 指数可预测 SYNTAX 评分的中/高值（≥ 23），并增加患中度至重度 CAD 的风险。
