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. |
