Discordant Values in Lower Extremity Physiologic Studies Predict Increased Cardiovascular Risk

摘要

Ankle‐brachial indexes ( ) are a noninvasive diagnostic tool for peripheral arterial disease and a marker of increased cardiovascular risk. is calculated using the highest systolic blood pressure of the 4 ankle arteries (bilateral dorsalis pedis and posterior tibial). Accordingly, patients may be assigned a normal when the result would be abnormal if calculated using one of the other blood pressure readings. Cardiovascular outcomes for patients with discordant s are undescribed.
