Ankle brachial index
Jump to navigation Jump to search
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."
Role in health care
Diagnosis of peripheral arterial disease
|81 consecutive patients referred for arterograms of any region.
• 17% had peripheral arterial disease
|ABI by auscultation||Doppler ABI < 0.9||71%||91%|
|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%|
|ABI by Doppler ultrasonography||Angiography||95%||> 95%|
