最近的一项数值研究通过模拟脉搏波在动脉树中的传播，研究了外周PWV测量在评估主动脉僵硬方面的潜在应用。在这篇评论中，我们提供了对动脉顺应性改变的模拟的额外分析。分析表明，当顺应性改变时，主动脉和外周脉搏通过时间(PTTS)之间的关系可能不是恒定的。因此，外周PWV测量在特定的临床环境中可能具有最大的实用价值，在这种情况下：可以假设顺应性的可能变化，允许根据外周PTT来估计主动脉PTT；或者，人们希望评估外周PWV随时间的变化。
A recent numerical study investigated the potential utility of peripheral PWV measurements for assessing aortic stiffness by simulating pulse wave propagation through the arterial tree. In this Comment we provide additional analysis of the simulations in which arterial compliances were changed. The analysis indicates that relationships between aortic and peripheral pulse transit times (PTTs) may not be constant when compliances change. Consequently, peripheral PWV measurements may have greatest utility in particular clinical settings in which either: an assumption can be made about possible changes in compliance, allowing aortic PTT to be estimated from peripheral PTT; or, one wishes to assess changes in peripheral PWV over time.
