In recent years, the assessment of systolic acceleration in lower-extremity peripheral artery disease (PAD) has been brought back into the spotlight, whatever measure is used: time (in s) or acceleration (in cm.s). Acceleration time (also called systolic rise time) and maximal acceleration are two different but very useful measurements of growing interest in PAD. A background of the historical development, physics rationale, semantics, and methods of measurement, as well as their strengths and weaknesses, are discussed herein. Acceleration time is a powerful tool for predicting significant arterial stenosis or for estimating the overall impact of PAD as it is highly correlated to the ankle or toe pressure indexes. It could even become a new diagnostic criterion for critical limb ischemia. Similarly, maximal systolic acceleration ratios are highly predictive of carotid or renal stenosis. However, the literature lacks reference standards or guidelines for the assessment of such variables, and their measurement techniques seem to differ between authors. We propose herein a semantic and measurement statement order to clarify and help standardize future research.
近年来，无论采用何种测量方式（时间，单位为秒；或加速度，单位为厘米·秒），下肢外周动脉疾病（PAD）的收缩期加速度评估再度成为焦点。加速度时间（也称为收缩期上升时间）和最大加速度是两种不同但非常有用的测量方法，在PAD中越来越受到关注。本文讨论了其历史发展背景、物理原理、语义及测量方法，以及它们的优缺点。加速度时间是预测严重动脉狭窄或评估PAD整体影响的有力工具，因为它与踝部或趾部压力指数高度相关。它甚至可能成为严重肢体缺血的新诊断标准。同样，最大收缩期加速度比值对颈动脉或肾动脉狭窄具有高度预测性。然而，文献中缺乏评估此类变量的参考标准或指南，而且不同作者的测量技术似乎也有所不同。我们在此提出一种语义和测量声明顺序，以澄清并帮助规范未来的研究。
