研究目的:

本研究采用血流介导的肱动脉内皮依赖性扩张的无创测量方法来观察替尓泊肽药物治疗对T2DM患者的内皮依赖性血管舒张功能的影响,探索其潜在的心血管保护作用机制,并证实其改善血管内皮功能的作用独立于降糖和减重效应。  

Objectives of Study:

This study employs a non-invasive measurement of flow-mediated dilation (FMD) of the brachial artery to observe the effects of tirzepatide treatment on endothelium-dependent vasodilation in patients with T2DM, explore its potential mechanism of cardiovascular protection, and demonstrate that its improvement in vascular endothelial function is independent of its glucose-lowering and weight-reducing effects.

药物成份或治疗方案详述:

 

Description for medicine or protocol of treatment in detail:

 

纳入标准:

1)确诊的T2DM患者(符合2023年WHO的诊断标准),T2DM病程≤6月,既往未使用过任何降糖药物(含口服药、GLP-1RA、胰岛素),仅通过生活方式干预; 2)年龄40-70岁,性别不限; 3)6.5%≤ HbA1c ≤8.5%;24≤ BMI <28kg/m^2; 4)血管内皮功能障碍:基线肱动脉血流介导的舒张功能(FMD)<6%(超声规范测定,两次均值);同时 NMD(硝酸甘油介导舒张)≥ 10%,以排除结构性血管病变; 5)血压 <140/90 mmHg;LDL-C ≤ 2.6 mmol·L?1,既往未使用降压、调脂药物; 6)同意参加临床试验且能按照研究要求及时随访者。

Inclusion criteria

1) Confirmed T2DM patients (meeting the diagnostic criteria of the 2023 WHO), with a disease course of T2DM ≤ 6 months, who have never used any hypoglycemic drugs (including oral hypoglycemic agents, GLP-1RA, and insulin) and have only received lifestyle intervention; 2) Age 40-70 years, gender unrestricted; 3) 6.5% <= HbA1c <= 8.5%; 24 <= BMI < 28 kg/m^2; 4) Endothelial dysfunction: baseline brachial artery flow-mediated dilation (FMD) < 6% (measured by ultrasound, average of two measurements); and NMD (nitroglycerin-mediated dilation) >= 10% to rule out structural vascular disease; 5) Blood pressure < 140/90 mmHg; LDL-C <= 2.6 mmol·L?1, and have never used antihypertensive or lipid-lowering drugs; 6) Agree to participate in the clinical trial and be able to follow up in a timely manner as required by the study.

排除标准:

Exclusion criteria:

1) A history of type 1 diabetes, acute diabetic complications, unconscious hypoglycemia, or pancreatitis; 2) Non-proliferative diabetic retinopathy, proliferative diabetic retinopathy, or diabetic macular edema requiring urgent treatment; 3) Allergy or contraindication to tirzepatide; 4) Gastroparesis; 5) Critical illness (such as cancer, severe infection, active tumor, autoimmune disease, etc.); 6) Previous occurrence of severe cardiovascular events (such as myocardial infarction, stroke, vascular reconstruction surgery or major surgical history); 7) Severe liver or kidney dysfunction (ALT/AST >= 3 times the upper limit of normal or eGF < 30 mL/min/1.73m^2); 8) Pregnant or lactating women; 9) Mental illness or inability to cooperate with follow-up.
