In recent years, the role of arterial stiffness in the development of cardiovascular diseases has been explored more extensively. Local arterial stiffness may be gauged via ultrasound, measuring pulse transit time relative to changing vessel diameters and distending pressures. Recently, direct vessel-wall tracking systems have been devised based on new ultrasonographic methodologies, such as tissue Doppler imaging and speckle-tracking analysis--vascular mechanics. These advances have been evaluated in varying arterial distributions, are proved surrogates of pulse wave velocity, and are ascending in clinical importance. In the course of this review, we describe fundamental concepts and methodologies involved in ultrasound assessment of vascular mechanics. We also present relevant clinical studies and discuss the potential clinical utility of such diagnostic pursuits.
近年来，动脉僵硬度在心血管疾病发展中的作用得到了更广泛的探索。可以通过超声测量脉搏波传导时间相对于血管直径和扩张压力的变化来评估局部动脉僵硬度。最近，基于组织多普勒成像和斑点跟踪分析等新的超声方法，已经设计出了直接血管壁跟踪系统，即血管力学。这些进展已经在不同的动脉分布中进行了评估，被证明是脉搏波速度的替代指标，并且在临床重要性上不断上升。在本综述中，我们描述了超声评估血管力学的基本概念和方法。我们还介绍了相关的临床研究，并讨论了这种诊断方法的潜在临床应用。
