In medicine and the physical examination, the ankle brachial index is the "comparison of the blood pressure between the brachial artery and the posterior tibial artery. it is a predictor of peripheral arterial disease."[1]
Method
The blood pressure at the posterior tibial artery can be measured by Doppler ultrasonography[2], palpation[3], or auscultation.[4]
Role in health care
Diagnosis of peripheral arterial disease
| Study | Patients | Test | Outcome | Results | |
|---|---|---|---|---|---|
| Sensitivity | Specificity | ||||
| Carmo, 2009[4] Cross-sectional study |
81 consecutive patients referred for arterograms of any region. • 17% had peripheral arterial disease |
ABI by auscultation | Doppler ABI < 0.9 | 71% | 91% |
| Migliacci, 2008[3] Cross-sectional study |
205 patients from 24 primary care physicians. Subjects has at least one major cardiovascular risk factor. • 4% had peripheral arterial disease |
ABI by palpation | Doppler ABI < 0.9 | 88% | 82% |
| Khan, 2006[2] Systematic review |
ABI by Doppler ultrasonography | Angiography | 95% | > 95% | |
Prediction vascular disease and mortality
A meta-analysis concluded that "measurement of the ABI may improve the accuracy of cardiovascular risk prediction beyond the FRS (Framingham risk score)".[5]
