Ankle-brachial index (ABI) test

Peripheral artery disease (PAD) can be predicted using the ankle-brachial index (ABI) test

Ankle-brachial index (ABI) test is a simple, noninvasive test that compares blood pressure in the ankle and arm

A ratio of less than 0.9 may indicate PAD in the legs

A normal ABI is between 0.9 and 1.4

A low ABI is an independent marker of cardiovascular risk

An ABI over 1.3-1.4 correlates with major adverse cardiovascular events

Risk factors of developing Peripheral Artery Disease (PAD)

- Age over 50 years

- Being a current or former smoker

- Diabetes

- High blood pressure

- High cholesterol

- Overweight (a body mass index of 25 or greater)

Useful of Ankle-Brachial Index test

- Diagnosis of lower extremity arterial disease.

- Assess the severity of lower extremity arterial disease

- For prediction of future cardiovascular events
