目前认为 ,心血管疾病的本质是血管结构与功能的异常 ,防治心血管疾病的重点在于防治血管病变。用于评价血管功能的动脉顺应性的定义为在单位压力改变下 ,血管面积、直径或体积的改变。它依赖于血管的几何和机械特性。动脉的扩张性、僵硬度、弹性与动脉顺应性意义相近。动脉顺 Currently, the nature of cardiovascular disease is abnormal vascular structure and function, prevention and treatment of cardiovascular disease focus on prevention and treatment of vascular disease. Arterial compliance, which is used to assess vascular function, is defined as the change in vascular area, diameter, or volume at a unit pressure change. It depends on the geometry and mechanical properties of the blood vessel. Artery expansion, stiffness, elasticity and arterial compliance similar meaning. Artery smooth
