The effects of high blood pressure on arterial vessels has become an important topic of research. These effects can be evaluated by analyzing three major components: systemic vascular resistance, arterial compliance and wave reflection. The increase in systemic vascular resistance and arterial stiffness produces modifications of left ventricular afterload and morphologic changes of pressure and flow waves. These effects can eventually cause structural changes of the left ventricle, an increase in oxygen consumption and a decrease in coronary perfusion. Until recently, invasive methods were the only means to evaluate arterial function. The aim of this review is to assess the usefulness of non invasive methods to determine the components of arterial impedance in order to evaluate the hemodynamic changes due to high blood pressure.
高血压对动脉血管的影响已成为一个重要的研究课题。这些影响可通过分析三个主要组成部分来评估：全身血管阻力、动脉顺应性和波反射。全身血管阻力和动脉僵硬度的增加会导致左心室后负荷的改变以及压力和血流波的形态变化。这些影响最终可导致左心室结构改变、氧消耗增加和冠状动脉灌注减少。直到最近，侵入性方法仍是评估动脉功能的唯一手段。本综述的目的是评估非侵入性方法在确定动脉阻抗成分以评估高血压引起的血流动力学变化方面的实用性。
