Peripheral arterial disease (PAD) is an important manifestation of atherosclerosis, with an estimated age-adjusted prevalence of approximately 13% in people older than 50 years. Noninvasive vascular laboratory physiologic studies are indispensable tools in the initial evaluation and workup and postintervention follow-up. In this review, we describe a practical approach to the technique, interpretation, pitfalls, and limitations of these physiologic studies. We also provide an algorithmic approach for using these studies in the initial workup of patients with suspected PAD. Noninvasive techniques that primarily provide anatomic information have not been included in this review.
外周动脉疾病（PAD）是动脉粥样硬化的一种重要表现，据估计，在50岁以上人群中，年龄调整后的患病率约为13%。无创血管实验室生理研究是初始评估、检查及干预后随访中不可或缺的工具。在本综述中，我们描述了这些生理研究的技术、解读、陷阱及局限性的实用方法。我们还提供了一种算法方法，用于在疑似PAD患者的初始检查中使用这些研究。本综述未纳入主要提供解剖学信息的无创技术。
