Peripheral Arterial Disease (PAD) and CVD in Adults: Risk Assessment with Ankle Brachial Index
Recommendations made by the USPSTF are independent of the U.S. government. They should not be construed as an official position of the Agency for Healthcare Research and Quality or the U.S. Department of Health and Human Services.
Clinical Summary of U.S. Preventive Services Task Force Recommendation
|Population||Asymptomatic adults without a known diagnosis of peripheral artery disease (PAD), cardiovascular disease, severe chronic kidney disease, or diabetes|
Grade: I statement
|Risk Assessment||Important risk factors for PAD include older age, diabetes, smoking, hypertension, high cholesterol level, obesity, and physical inactivity. Peripheral artery disease is more common in men than women and occurs at an earlier age in men.|
|Screening Tests||Resting ankle–brachial index (ABI) is the most commonly used test in screening for and detection of PAD in clinical settings. It is calculated as the systolic blood pressure obtained at the ankle divided by the systolic blood pressure obtained at the brachial artery while the patient is lying down. Physical examination has low sensitivity for detecting mild PAD in asymptomatic persons.|
|Balance of Benefits and Harms||Evidence on screening for PAD with the ABI in asymptomatic adults with no known diagnosis of cardiovascular disease or diabetes is insufficient; therefore, the balance of benefits and harms cannot be determined.|
|Other Relevant USPSTF Recommendations||The USPSTF has made recommendations on using nontraditional risk factors, including the ABI, in screening for coronary heart disease. These recommendations are available at http://www.uspreventiveservicestaskforce.org.|
