Screening for Peripheral Artery Disease and Cardiovascular Disease Risk Assessment With the Ankle-Brachial Index in Adults: U.S. Preventive Services Task Force Recommendation Statement

Description: Update of the 2005 U.S. Preventive Services Task Force (USPSTF) recommendation on screening for peripheral artery disease (PAD). Methods: The USPSTF reviewed the evidence on the use of resting ankle-brachial index (ABI) as a screening test for PAD or as a risk predictor for cardiovascular disease (CVD). The review focused on resting ABI as the sole screening method; the diagnostic performance of ABI testing in primary care populations, unselected populations, and asymptomatic populations; the predictive value of ABI testing for major CVD outcomes in primary care or unselected populations; and the effect of treatment on general CVD and PAD-specific morbidity in patients with asymptomatic or minimally symptomatic PAD. Population: This recommendation applies to asymptomatic adults who do not have a known diagnosis of PAD, CVD, severe chronic kidney disease, or diabetes. Recommendation: The USPSTF concludes that the current evidence is insufficient to assess the balance of benefits and harms of screening for PAD and CVD risk assessment with the ABI in adults.
