To determine whether you might have peripheral artery disease (PAD), your doctor will ask about your history of cardiovascular disease, diabetes, high blood pressure and high cholesterol. He or she may also ask about your diet, medications and symptoms, such as leg pain and weakness.
Your legs will be examined, and your pulse and temperature will be checked. The doctor also will perform a painless test called an ankle brachial index (ABI), which compares blood pressure readings from your arms and legs. You may be sent for blood tests or such imaging tests, such as computer tomography (CT), magnetic resonance angiography (MRA, a type of MRI) or a Doppler ultrasound to pinpoint blocked or narrowed arteries.
