Question: 1 / 400

Which assessment method is used to categorize the severity of peripheral artery disease?

Thigh circumference measurement

Ankle-brachial index measurement

The ankle-brachial index (ABI) measurement is the appropriate method to categorize the severity of peripheral artery disease (PAD). This test involves comparing the blood pressure in the ankle with the blood pressure in the arm, providing a non-invasive and straightforward assessment of arterial blood flow. A lower ABI indicates more severe PAD and correlates with a worse prognosis for cardiovascular outcomes.

The importance of the ABI lies in its ability to quantitatively assess the severity of the disease, helping clinicians determine appropriate management and intervention strategies. It is widely accepted in clinical practice as a reliable diagnostic tool for evaluating the presence and severity of peripheral artery disease.
