Ankle Brachial Index

The ankle brachial index (ABI) is a noninvasive test used to determine a patient’s risk for peripheral artery disease, a condition that involves a narrowing of the arteries in the leg and can lead to a heart attack or stroke.

The Ankle Brachial Index (ABI) uses a Doppler device to detect blood flow within the ankle and arm, and then compares these two results to properly assess a patient’s risk. Blood pressure that is lower in the leg than in the arm may be a sign of a blocked artery.

Recent studies in the AMA Journal recognize the usefulness and value of ABI testing for the evaluation of cardiovascular risk. The study states these tests are under-utilized in routine clinical practice because:

  • Most clinicians are not aware that a low ABI is a marker of cardiovascular risk
  • It is perceived as a specialist test
  • Most clinicians would not know how to perform the test

Our service will accurately perform this test and enable your practice to treat the patient in the most efficacious manner.
