Ankle-Brachial Index (ABI)
Diagnoses and grades severity of peripheral arterial disease (PAD). ABI = ankle systolic BP / brachial systolic BP. Predicts cardiovascular risk.
Score interpretation
→ Secondary prevention: antiplatelet, statin, smoking cessation; repeat ABI in 1-2 years; supervised exercise programme
→ Vascular surgery referral; supervised exercise programme (6 months); antiplatelet + statin; blood pressure control; duplex USS
→ Urgent vascular surgery assessment; toe-brachial index or pulse wave if non-compressible; angiogram; revascularisation; wound care; critical limb team
Interpretation bands for the Ankle-Brachial Index. Apply clinical judgement and local guidance.
