Despite its validity as a screening test for peripheral arterial disease (PAD), and its prognostic value, the ankle-brachial index (ABI) is infrequently used in primary care, probably because a Doppler device is required, along with the requisite skill for its use. We hypothesized that ABI could be accurately measured either by pulse palpation (pABI) or automatic blood pressure devices (autoABI) instead of Doppler method (dABI).
