Ankle brachial index test evaluates blood flow to your legs

This non-invasive heart test enables your cardiologist to determine if there is any narrowing or restriction of an artery or blood vessel that reduces blood flow, how serious the blockage is and exactly where it is located.

This test is done by measuring blood pressure at the ankle and in the arm while a person is at rest.

What to expect

During the ankle brachial index test

The stress technician will start by taking or reviewing your medical history.

You will be asked to lie on your back while standard blood pressure cuffs are placed around your ankles and arms.

The cuffs will be inflated, and a small ultrasound probe will be placed against the leg. As the cuffs are deflated, waveforms will be documented assessing blood flow to your heart.

Who will give me the results of the ankle brachial index test?

After a review of the test, your medical history, other imaging modalities and previous tests by a Baylor Scott & White Legacy Heart Center cardiologist in Plano, a report will be sent to the ordering physician.

The ordering physician will then review the results and discuss them with you.
