RT Journal Article SR Electronic T1 Using the ankle-brachial index to diagnose peripheral artery disease and assess cardiovascular risk JF Cleveland Clinic Journal of Medicine JO Cleve Clin J Med FD Cleveland Clinic SP 651 OP 661 DO 10.3949/ccjm.79a.11154 VO 79 IS 9 A1 Esther S. H. Kim A1 Keattiyoat Wattanakit A1 Heather L. Gornik YR 2012 UL http://www.ccjm.org/content/79/9/651.abstract AB The ankle-brachial index is valuable for screening for peripheral artery disease in patients at risk and for diagnosing the disease in patients who present with lowerextremity symptoms that suggest it. The ankle-brachial index also predicts the risk of cardiovascular events, cerebrovascular events, and even death from any cause. Few other tests provide as much diagnostic accuracy and prognostic information at such low cost and risk.
