Ankle-brachial index measurement only when prompted by symptoms leaves most cases of peripheral artery disease unrecognized because the majority of patients are asymptomatic.
T he ankle-brachial index (ABI) is widely accepted as a diagnostic test used to evaluate the presence of lower extremity peripheral artery disease (PAD) in patients with symptoms of intermittent claudication or rest ischemia.[1][2][3] However, the majority of patients with PAD are asymptomatic; therefore, measurement of the ABI only when prompted by symptoms will result in most cases of PAD going unrecognized.

Perlstein et al. (2009) conducted a review in Peripheral artery disease (PAD) / Cardiovascular risk. Ankle-brachial index (ABI) was evaluated. Ankle-brachial index measurement only when prompted by symptoms leaves most cases of peripheral artery disease unrecognized because the majority of patients are asymptomatic.
