Predictors of an abnormal postexercise ankle brachial index: Importance of the lowest ankle pressure in calculating the resting ankle brachial index.

ABSTRACT:

Background

The postexercise ankle-brachial index (ABI) is useful in patients with suspected peripheral arterial disease (PAD) and a normal resting ABI. Our objective was to determine the independent predictors of an abnormal postexercise ABI.

Hypothesis

We hypothesized that the lowest ankle systolic pressure to calculate the resting ABI would be associated with an abnormal post-exercise ABI.

Methods

Among 619 consecutive patients referred for suspected PAD, we calculated the postexercise ABI in patients with a normal resting ABI. An ABI <0.90 at rest was considered abnormal. We investigated 3 definitions of an abnormal postexercise ABI, defined as either <0.90, or >5% or >20% reduction compared with rest.

Results

Using multivariate analysis, the lowest ABI (cal
