Postexercise Ankle-Brachial Index Testing to Diagnose Peripheral Artery Disease —Reply

In Reply Dr Mah é and colleagues are concerned about the sensitivity and specificity of the thresholds used for diagnosing PAD in patients with normal (1.00-1.40) or borderline (0.91-0.99) resting ABI and exertional non–joint-related leg pain. The diagnostic threshold of either a postexercise ABI decrease of mor e than 20% or a postexercise ankle systolic pressure decrease of more than 30 mm Hg were suggested by Aboyans et al as a reasonable diagnostic criterion for PAD (recommendation class IIa; level of evidence A) in the 2012 American Heart Association scientific statement on measurement and interpretati on of the ABI.
