目的

探讨早发心肌梗死(AMI)患者甘油三酯葡萄糖(TyG)指数的变化及其临床意义。

方法

回顾性分析2021年1月至2022年12月在常州市武进人民医院心内科住院明确诊断的早发AMI 110例患者,其中男性88例(80.00%),女性22例(20.00%);年龄22~64岁,平均(47.60±8.35)岁。选择同期住院缺乏典型心绞痛症状,冠脉造影显示主要冠脉血管(≥2.0 mm)狭窄<50%,并且发病年龄男性˂55岁或女性˂65岁的患者为对照组,其中男性80例(33.76%),女性157例(66.24%);年龄29~64岁,平均(53.33±6.65)岁。比较两组间的TyG指数,按性别进行亚组分析,采用Logistic回归分析探讨TyG与早发AMI的相关性,并采用受试者工作曲线(ROC)分析TyG对早发AMI的诊断价值。

结果

早发AMI组年龄、HDL-C水平显著低于对照组;而男性比例、空腹血糖、LDL-C、HbA1C水平显著高于对照组。早发AMI组TyG指数显著高于对照组(10.53±0.78比10.20±0.55,P<0.001)。按性别进行亚组分析,无论是男性还是女性亚组,早发AMI组TyG指数均显著高于对照组。Logistic回归结果显示,TyG指数是早发AMI的独立相关因素(OR=1.664,95%CI=1.102~2.513,P=0.015)。TyG指数诊断早发AMI ROC曲线下面积为0.634(95% CI=0.570~0.698,P<0.001),敏感度和特异度分别为0.545、0.692。

结论

TyG指数在早发AMI患者中显著升高,与早发AMI密切相关。

Objective

To investigate the changes in the triglyceride-glucose (TyG) index and its clinical value in patients with premature acute myocardial infarction (AMI).

Methods

A retrospective analysis was conducted on 110 patients with premature AMI who were hospitalized and definitively diagnosed in the Department of Cardiology at Changzhou Wujin People's Hospital from January 2021 to December 2022. Patients ranged in age from 22 to 64 years (average 47.60±8.35 years). Of these, 88 (80.00%) were male and 22 (20.00%) were female. For comparison, patients hospitalized during the same period were selected as controls. These control patients lacked typical angina symptoms, showed stenosis of <50% in major coronary vessels (≥2.0 mm) on coronary angiography, and had an age of onset of <55 years for males or <65 years for females. Ages ranged from 29 to 64 years (mean 53.33±6.65). Of these, 80 were men (33.76%) and 157 were women (66.24%). The TyG index was compared between the two groups, and subgroup analysis was performed by gender. Logistic regression analysis was used to explore the association between the TyG index and premature AMI, and receiver operating characteristic (ROC) curve analysis was employed to evaluate the diagnostic value of the TyG index for premature AMI.

Results

Patients in the premature AMI group had significantly lower age and HDL-C levels than the control group, while exhibiting significantly higher proportions of males, fasting blood glucose, LDL-C, and HbA1c levels. The TyG index was significantly higher in the premature AMI group compared to the control group (10.53±0.78 vs. 10.20±0.55, P<0.001). Subgroup analysis by sex revealed that the TyG index remained significantly higher in the premature AMI group for both male and female subgroups. Logistic regression results indicated that the TyG index was an independent influencing factor for premature AMI (OR=1.664, 95% CI=1.102-2.513, P=0.015). The area under the ROC curve for the TyG index in diagnosing premature AMI was 0.634 (95% CI: 0.570-0.698, P<0.001), with a sensitivity of 0.545 and specificity of 0.692.

Conclusion

The TyG index is significantly elevated in patients with premature AMI and is an independent correlated factor for premature AMI.
