Overview
Screening
2011 ACCF/AHA Focused Update of the Guideline for the Management of Patients With Peripheral Artery Disease (Updating the 2005 Guideline) (DO NOT EDIT)
| Class I |
| "1. The resting ABI should be used to establish the lower extremity PAD diagnosis in patients with suspected lower extremity PAD, defined as individuals with 1 or more of the following: exertional leg symptoms, nonhealing wounds, age 65 years and older, or 50 years and older with a history of smoking or diabetes.(Level of Evidence: A)" |
| "2. The ABI should be measured in both legs in all new patients with PAD of any severity to confirm the diagnosis of lower extremity PAD and establish a baseline.(Level of Evidence: A)" |
| "3. The toe-brachial index should be used to establish the lower extremity PAD diagnosis in patients in whom lower extremity PAD is clinically suspected but in whom the ABI test is not reliable due to noncompressible vessels (usually patients with long-standing diabetes or advanced age). (Level of Evidence: A)" |
| "4. Leg segmental pressure measurements are useful to establish the lower extremity PAD diagnosis when anatomic localization of lower extremity PAD is required to create a therapeutic plan. (Level of Evidence: A)" |
| "5. ABI results should be uniformly reported with noncompressible values defined as greater than 1.40, normal values 1.00 to 1.40, borderline 0.91 to 0.99, and abnormal 0.90 or less. (Level of Evidence: A)" |
Ankle Brachial Index (ABI)
The ABI is a screening test for the assessment for the presence of PAD.
- Ratio of the ankle blood pressure divided by the highest brachial blood pressure
- Normal is 0.9 to 1.3
- The exercise ABI is done by having the patient stand on their toes repeatedly as exercies. The ABI is rechecked after exercise. This test is done if the patient has symptoms with exercise and a normal ABI at rest.
