Peripheral artery disease (PAD) is an atherosclerotic disease that causes obstruction in lower limb arteries. It increases cardiovascular risk even in asymptomatic patients. Accurate diagnostic tools for identification of affected individuals are needed. Recently, there have been attempts to establish a reliable method of automated ankle-brachial index (ABI) identification. A search of PubMed database to identify studies assessing automatic ABI measurements in agreement with standard PAD diagnosis methods was conducted in December 2020. A total of 57 studies were analyzed in the review. The majority of analyzed studies found ABI measured by automatic oscillometric devices to be potentially feasible for use. Some note that, even though the Doppler and oscillometric methods are not fully interchangeable, the oscillometric devices could be used in screening. Significantly fewer publications are available on automatic plethysmographic devices. For photoplethysmography, most studies reported either good or moderate agreement with reference standards. For air plethysmography, poorer agreement with Doppler ABI is suggested. It is noted that pulse volume recording (PVR) function may improve the diagnostic accuracy of the devices.
外周动脉疾病（PAD）是一种动脉粥样硬化疾病，可导致下肢动脉阻塞。即使在无症状患者中，它也会增加心血管风险。因此需要准确的诊断工具来识别受影响的个体。最近，人们尝试建立一种可靠的自动踝臂指数（ABI）识别方法。2020年12月，我们检索了PubMed数据库，以确定评估自动ABI测量与标准PAD诊断方法一致性的研究。本综述共分析了57项研究。大多数分析研究发现，通过自动示波装置测量的ABI可能具有可行性。一些研究指出，尽管多普勒法和示波法不能完全互换，但示波装置可用于筛查。关于自动体积描记装置的出版物明显较少。对于光电容积描记法，大多数研究报告与参考标准的一致性良好或中等。对于空气体积描记法，与多普勒ABI的一致性较差。值得注意的是，脉搏容积记录（PVR）功能可能会提高这些装置的诊断准确性。
