If you have signs of peripheral artery disease (PAD), it’s important to talk with a health care provider. Several conditions, including nerve problems, can cause similar symptoms, so getting the right diagnosis matters.
PAD happens when blood vessels in the legs become narrow or blocked. When found early, treatment can improve blood flow, ease pain and help prevent serious complications like non-healing wounds and amputations. PAD also raises your risk of heart attack and stroke, so early diagnosis helps protect your overall heart health.
If you smoke or have diabetes, high blood pressure or high cholesterol, ask your doctor about PAD screening during your regular checkups.
To diagnose PAD, your provider will review your medical history and examine your legs and feet for signs like weak pulses, changes in skin color or sores that won’t heal. They may also use one or more of these tests:
Compares blood pressure in your ankles and arms to check for reduced blood flow.
Uses sound waves to show the speed and direction of blood flow and locate narrowing or blockages.
A contrast dye is injected into your blood vessels so they can be seen on imaging. It helps identify narrowed or blocked areas and is often used when planning treatment.
Creates detailed images of blood vessels without the need for X-rays.
Provides cross-section and 3D images to help locate blockages and assess artery health.
A six-minute walk test helps show how PAD affects mobility and daily life.
Check cholesterol and blood sugar levels that may increase PAD risk.
Your provider may classify PAD based on your symptoms:
This staging helps determine the best treatment plan for you.
If PAD is diagnosed, your provider will talk with you about treatment options to improve blood flow, manage symptoms and reduce your risk of heart and vascular complications.
