Validity intra- and inter-observer reliability of automated devices for the assessment of ankle brachial index using photo-plethysmography

摘要

BackgroundAnkle-brachial-Index (ABI) measured by manual Dopplersonography is an easily assessable marker of global cardiovascular risk. The aim of this study was to establish novel photo-plethysmography (PPG)-based ABI assessments in an epidemiologic context and to compare its results with those of Doppler.
