ankle-brachial index

(redirected from Ankle Brachial Index)

ankle-brachial index (ABI),

objective measurement of arterial insufficiency based on the ratio of ankle systolic pressure to brachial systolic pressure. An ABI of 1.0 indicates absence of arterial insufficiency; an ABI of less than 0.50 indicates severe arterial insufficiency.

ankle-brachial index (ABI)

the ratio of ankle systolic pressure to the arm systolic pressure, used in assessing the status of lower extremity arteries. It is calculated by dividing the higher of the left and right ankle pressures by the higher of the two brachial artery pressures. Also called ankle-arm index.

ankle-brachial index

The ankle-to-arm ratio of systolic blood pressure, which is useful in diagnosing peripheral arterial disease.

Systolic pressure ratio (A/B)Interpretation
0.9-1.1Normal
0.5-0.9Arterial compromise/impaired arterial supply to lower leg/foot; patient may report claudication
<0.5Severe arterial supply/frank ischaemia of lower leg and foot; patient may report rest pain

In this study, we aimed to evaluate CD146 and PWV as non-invasive methods for prediction of early vascular affection in SLE patients without symptoms of vascular disease, to detect the outcome and reproducibility of these methods, and to correlate CD146 and PWV with lipid profile, intima media thickness (IMT), and ankle brachial index.
