Authors' objectives: We conducted a systematic evidence review on the diagnostic and prognostic value of the resting ankle-brachial index (ABI) in unselected populations. This review also examined the benefit and harms of treating generally asymptomatic persons with peripheral artery disease (PAD). We conducted this review to support the U.S. Preventive Services Task Force in updating its recommendation on screening for PAD.
Authors' recommendations: There is very limited evidence examining the diagnostic accuracy of the ABI as a screening tool (one study) or examining the treatment of generally asymptomatic persons with PAD or a low ABI (two trials). However, there is a large body of evidence (18 population-based cohorts) suggesting that a low ABI is independently associated with increased CAD and CVD risk, after adjusting for FRS factors. Despite this association, the magnitude of risk reclassification of ABI in addition to FRS is still unclear and is likely small. The net reclassification may have the largest impact among persons age 65 years and older and persons at the thresholds of FRS risk categories.
