摘要:

目的 探讨甘油三酯-葡萄糖(TyG)指数对下肢动脉硬化闭塞症患者介入治疗后再狭窄的预测价值。方法 回顾性分析210例接受介入治疗的下肢动脉硬化闭塞症患者临床资料,根据TyG指数分为低TyG组(TyG<7.70,75例)、中TyG组(7.70≤TyG≤8.50,80例)和高TyG组(TyG>8.50,55例)。比较3组患者临床特征,采用单因素分析筛选再狭窄相关因素,通过Cox比例风险回归分析确定独立影响因素;绘制受试者工作特征(ROC)曲线评估TyG指数对再狭窄的预测效能,采用Kaplan-Meier法比较不同TyG指数患者再狭窄的发生情况。结果 高TyG组患者年龄、体质量指数(BMI)、糖尿病患病比例、病变长度及支架置入比例均高于低TyG组和中TyG组(P<0.05)。术后随访6~24个月,平均(15.36±4.25)个月,全组再狭窄发生率为34.76%(73/210),其中轻度26例(35.62%)、中度24例(32.88%)、重度23例(31.50%)。低、中、高TyG组再狭窄率依次升高(21.33%、35.00%、52.73%)。Cox比例风险回归分析表明,TyG指数升高(HR=3.245,95%CI:1.987~5.316,P<0.001)是再狭窄的独立危险因素。Kaplan-Meier分析显示,高TyG组再狭窄率高于低TyG组和中TyG组(Log-rank χ2=13.951,P<0.01)。结论 TyG指数可作为下肢动脉硬化闭塞症患者介入治疗后再狭窄的有效预测指标,TyG指数越高,患者术后再狭窄风险越高。

Abstract:

Objective To explore the predictive value of the triglyceride-glucose (TyG) index for restenosis in patients with lower extremity arteriosclerotic occlusive disease after interventional therapy. Methods A retrospective analysis was conducted on the clinical data of 210 patients with lower extremity arteriosclerotic occlusive disease who received interventional treatment. The patients were divided into the low TyG group (TyG<7.70, n=75), the medium TyG group (7.70≤TyG≤8.50, n=80) and the high TyG group (TyG>8.50, n=55) based on the TyG index. The clinical characteristics of the three groups were compared. Univariate analysis was used to screen the factors related to restenosis, and Cox proportional hazards regression analysis was used to determine the independent influencing factors. The receiver operating characteristic (ROC) curve was drawn to evaluate the predictive efficacy of the TyG index for restenosis, and the Kaplan-Meier method was used to compare the occurrence of restenosis in patients with different TyG levels. Results The patient age, body mass index (BMI), prevalence of diabetes, lesion length and stent implantation rate were higher in the high TyG group compared with those of the low TyG group and the medium TyG group (P<0.05). After 6 to 24 months of postoperative follow-up, with an average of (15.36±4.25) months, the restenosis rate of the entire group was 34.76% (73/210), including 26 cases (35.62%) of mild restenosis, 24 cases (32.88%) of moderate restenosis and 23 cases (31.50%) of severe restenosis. The restenosis rates of the low, medium and high TyG groups increased successively (21.33% vs. 35.00% vs. 52.73%). Cox proportional hazards regression analysis showed that an elevated TyG index (HR=3.245, 95%CI: 1.987-5.316, P<0.001) was an independent risk factor for restenosis. Kaplan-Meier analysis revealed that the restenosis rate of the high TyG group was higher than that of the low TyG group and the medium TyG group (Log-rank χ2=13.951, P<0.01). Conclusion The TyG index can serve as an effective predictor for restenosis in patients with lower extremity arteriosclerotic occlusive disease after interventional treatment. The higher the TyG index, the higher the risk of restenosis after the operation.
