摘要:

目的 · 探讨基线脂代谢谱与降糖药物格列吡嗪和二甲双胍干预后心血管结局的关系,寻找能够预测格列吡嗪和二甲双胍长期心 血管效应的脂质组分。方法 · 选取 116 例分别接受格列吡嗪(56 例)和二甲双胍(60 例)治疗 3 年的 2 型糖尿病(T2DM)合并冠状动 脉粥样硬化性心脏病(CHD)患者,运用液相色谱 -四级杆飞行时间质谱联用技术(LC-QTOF/MS)测定基线血清中的 119 种脂质组分。 随访所有患者心血管复合终点(包括心血管死亡、全因死亡、非致命性心肌梗死、非致命性脑卒中及冠脉血运重建)的发生情况。通过 Logistic 回归分析脂质组分与患者心血管复合终点的关系。采用连续净重新分类指数(cfNRI)和整体鉴别指数(IDI)评价基线脂质组分 是否有助于提高对再发心血管事件的预测能力。结果 · 除利尿剂使用率和 PC(O-34:2)及 SM(d18:0-24:0)水平外,2 组间基线药物分 布及临床特征和生化指标的差异均无统计学意义。Logistic 回归分析结果显示:基线 ChE(20:4)是格列吡嗪组患者再发心血管事件的保 护性因素(OR=0.87,P=0.039); ChE(20:4)显著提高了心血管复合终点的cfNRI 和 IDI,分别为69% 和 0.07(P=0.011,P=0.028)。基 线 SM(d18:1-22:0)是二甲双胍组患者和全部受试者再发心血管事件的危险因素(OR=1.65,P=0.039;OR=1.64,P=0.014); SM(d18:122:0)显著提高了二甲双胍组和全部受试者的心血管复合终点的 cfNRI,分别为 74% 和55%(P=0.012,P=0.005)。 结论 · 在由 LC-QTOF/ MS 方法测得的 119 种脂质组分中,基线 ChE(20:4)和 SM(d18:1-22:0)可分别为 T2DM 合并 CHD 患者接受格列吡嗪和二甲双胍长期 治疗后出现心血管复合终点的保护性和危险因素,且均有助于提高预测再发心血管事件风险的准确性。

Abstract:

 Objective · To explore the relationship between baseline lipid profiles and long-term cardiovascular outcomes after intervention with hypoglycemic drugs metformin and glipizide and to detect lipid components that can predict the long-term cardiovascular effect of metformin and glipizide.  Methods · Liquid chromatography–quadrupole time of flight–mass spectrometry (LC-QTOF/MS) was used to measure 119 lipid components in baseline serum for 116 patients with type 2 diabetes (T2DM) and atherosclerotic heart disease (CHD) who were treated with glipizide (56 cases, the glipizide group) or metformin (60 cases, the metformin group). Cardiovascular complex end points (including cardiovascular death, all-cause death, nonfatal myocardial infarction, nonfatal stroke, and arterial revascularization) of all patients were followed up. The relationship between lipid components and cardiovascular  complex end points was analyzed with Logistic regression analysis. The category-free net reclassification index (cfNRI) and the integrated discrimination improvement (IDI) were used to evaluate whether lipid components are helpful for predicting the recurrent cardiovascular events.  Results · The differences in baseline drug distribution, clinical characteristics, and biochemical indexes between two groups were not statistically significant, except for diuretics use, serum PC (O-34:2) level, and SM (d18:0-24:0) level. Logistic regression analysis showed that baseline ChE (20:4) was a protective factor for recurrent cardiovascular events in the glipizide group (OR=0.87, P=0.039). ChE (20:4) significantly increased the cfNRI and IDI of cardiovascular  complex end points by 69% and 0.07, respectively (P=0.011, P=0.028). Baseline SM (d18:1-22:0) was a risk factor for recurrent cardiovascular events in the metformin group and all participants (OR=1.65, P=0.039; OR=1.64, P=0.014). SM (d18:1-22:0) significantly increased the cfNRI of cardiovascular  complex end points in the metformin group and all participants by 74% and 55%, respectively (P=0.012, P=0.005).  Conclusion · Of 119 lipid components measured with LC-QTOF/ MS, baseline ChE (20:4) is a protective factor and SM (d18:1-22:0) is a risk factor for cardiovascular  complex end points in with T2DM and CHD patients after long-term treatment with metformin and glipizide. Both lipid components are helpful for improving the prediction of recurrent cardiovascular events.
