内皮细胞通过释放内皮源性舒张因子和内皮源性收缩因子,控制着血管的舒张和收缩,在调节血管紧张度方面发挥着关键作用。内皮功能失调是触发或促进动脉粥样硬化等心血管疾病发生的关键因素。血管内皮功能受损是动脉粥样硬化的一个早期标志,在动脉粥样硬化病变形成前即可出现。动 Endothelial cells play a key role in the regulation of vascular tone by controlling the relaxation and contraction of blood vessels by releasing endothelium-derived relaxing factors and endothelium-derived contraction factors. Endothelial dysfunction is a key factor that triggers or promotes the development of cardiovascular diseases such as atherosclerosis. Vascular endothelial dysfunction is an early sign of atherosclerosis that occurs before atherosclerotic lesions develop. move
