What value on the ankle-brachial index diagnoses peripheral artery disease?

Question

Quizplus · Accepted Answer

An ankle-brachial index (ABI) of less than 0.90 is considered diagnostic for peripheral artery disease (PAD). An ABI of 0.90 to 1.00 is considered normal, and an ABI greater than 1 may indicate non-compressible arteries. An ABI of less than 0.50 may indicate severe PAD and a high risk for complications such as ulcers or gangrene, but it is not the diagnostic threshold. An ABI of less than 0.25 is extremely severe and associated with critical limb ischemia, but it is not the diagnostic threshold either.
