Peripheral artery disease, or PAD, happens when narrowed or blocked arteries reduce blood flow to the legs or other parts of the body. It is often related to atherosclerosis, the same plaque-building process that can affect arteries in the heart and brain.
PAD may cause leg pain with walking, cramping, tiredness, numbness, weakness, cold feet, slow-healing sores, or skin and nail changes. Some people have no obvious symptoms, which can make PAD easy to miss.
This checklist can help you prepare for a visit with your primary care clinician, cardiologist, vascular medicine specialist, vascular surgeon, podiatrist, or rehabilitation team. Bring a list of symptoms, walking limits, foot concerns, medication list, smoking history, diabetes results, blood pressure readings, cholesterol results, prior procedures, and questions about exercise, medicines, and follow-up.
Why Questions Matter With PAD
PAD is not only a leg problem. It is a blood vessel disease that can raise the risk of heart attack, stroke, limb complications, poor wound healing, and reduced quality of life.
The CDC explains that PAD is narrowing or blockage of vessels that carry blood from the heart to the legs. The classic symptom is leg pain with physical activity, such as walking, that improves after rest. The CDC also notes that people with PAD are at risk for coronary artery disease and cerebrovascular disease, which can lead to heart attack or stroke.
The 2024 ACC/AHA multisociety guideline emphasizes that PAD care should include medical therapies to reduce cardiovascular and limb events, including antiplatelet or antithrombotic therapy, lipid-lowering therapy, blood pressure treatment, diabetes management, smoking cessation, structured exercise, foot care, and follow-up.
Checklist Step 1: Ask Whether Your Symptoms Fit PAD
PAD symptoms can be classic, subtle, or absent. Some people describe calf pain when walking. Others notice tired legs, slow walking, weakness, coldness, numbness, or wounds that do not heal.
- “Do my symptoms sound like PAD?”
- “Could my leg pain be claudication?”
- “Could spine, arthritis, neuropathy, vein disease, or muscle problems be causing similar symptoms?”
- “What symptoms should I track before my next visit?”
The American Heart Association says the most common symptom of lower-extremity PAD is leg pain during activity. PAD may also cause cramping, fatigue, heaviness, aching, or discomfort in the leg or buttock muscles that improves with rest.
Checklist Step 2: Ask About the Ankle-Brachial Index Test
The ankle-brachial index, or ABI, compares blood pressure in the ankle with blood pressure in the arm. It is a common, noninvasive test used to help diagnose PAD.
- “Do I need an ankle-brachial index test?”
- “Should my ABI be measured at rest, after exercise, or both?”
- “What does my ABI result mean?”
- “Do I need ultrasound or other imaging?”
The American Heart Association explains that PAD diagnosis begins with a medical history and physical exam, and that tests may include the ankle-brachial index and imaging of the arteries when needed.
Checklist Step 3: Ask How Serious Your PAD Is
PAD severity depends on symptoms, walking ability, blood flow testing, wounds, rest pain, tissue loss, and overall heart and limb risk.
- “Is my PAD mild, moderate, severe, or limb-threatening?”
- “Do I have claudication, chronic limb-threatening ischemia, or another PAD pattern?”
- “Do I have reduced pulses or skin changes?”
- “What signs would suggest worsening blood flow?”
The American Heart Association notes that chronic limb-threatening ischemia is a severe type of PAD, and clinicians may use wound, ischemia, and foot infection assessments to understand severity and guide treatment.
Checklist Step 4: Ask About Heart Attack and Stroke Risk
Because PAD is usually a sign of atherosclerosis, your care plan should include cardiovascular risk reduction, not only leg symptom management.
- “What is my heart attack and stroke risk?”
- “Do I need cholesterol treatment, blood pressure treatment, or diabetes management changes?”
- “Should I be checked for coronary artery disease or carotid disease?”
- “Which risk factor should we treat most aggressively first?”
The American Heart Association states that people with PAD have a higher risk of coronary artery disease, heart attack, and stroke. It encourages people with leg or foot concerns to talk with a doctor about PAD and ask to take off their socks for an exam.
Checklist Step 5: Ask About Cholesterol Treatment
People with PAD often need intensive cholesterol management, even if cholesterol numbers do not seem extremely high. The goal is to reduce plaque-related risk throughout the body.
- “Do I need a statin?”
- “Should it be high-intensity?”
- “What LDL cholesterol goal or reduction are we aiming for?”
- “If a statin is not enough or not tolerated, what comes next?”
The 2024 ACC/AHA PAD guideline states that effective medical therapies for PAD include lipid-lowering therapy, specifically high-intensity statin therapy, to prevent major cardiovascular and limb events.
Checklist Step 6: Ask About Antiplatelet or Antithrombotic Therapy
Some people with PAD are prescribed medicines that reduce clot-related risk, such as antiplatelet therapy. In selected patients, additional antithrombotic therapy may be considered depending on bleeding risk and procedure history.
- “Do I need aspirin, clopidogrel, or another antiplatelet medicine?”
- “Do I need any antithrombotic therapy after a procedure?”
- “What bleeding symptoms should I watch for?”
- “Should I stop these medicines before dental work, surgery, or procedures?”
The 2024 ACC/AHA guideline includes antiplatelet and antithrombotic therapy among effective medical therapies for PAD, alongside lipid-lowering treatment, blood pressure treatment, diabetes management, and smoking cessation.
Checklist Step 7: Ask About Blood Pressure and Diabetes
High blood pressure and diabetes can worsen vascular risk. Diabetes can also increase the risk of foot wounds, infection, neuropathy, and limb complications.
- “What blood pressure goal is right for me?”
- “Do I need home blood pressure monitoring?”
- “What A1C or glucose goal is appropriate?”
- “How do diabetes, kidney disease, or neuropathy change my PAD care?”
The 2024 PAD guideline highlights antihypertensive therapy and diabetes management as key parts of PAD medical therapy and risk reduction.
Checklist Step 8: Ask About Smoking and Nicotine Support
Smoking is one of the strongest PAD risk factors and can worsen blood vessel damage, walking symptoms, wound healing, and procedure outcomes.
- “How much does smoking or nicotine affect my PAD?”
- “What support can help me quit?”
- “Are nicotine replacement, medications, counseling, or quitline support appropriate?”
- “Does vaping or smokeless tobacco affect my vascular risk?”
The ACC’s summary of the 2024 guideline lists tobacco use among PAD risk amplifiers and notes that smoking cessation interventions are recommended for PAD care.
Checklist Step 9: Ask About Structured Exercise Therapy
Walking can be difficult with PAD, but structured exercise therapy is one of the main treatments for chronic symptomatic PAD. It is more specific than simply being told to “walk more.”
- “Am I a candidate for supervised exercise therapy?”
- “What walking plan should I follow?”
- “How much discomfort is acceptable during walking?”
- “What should make me stop or call?”
The 2024 PAD guideline states that structured exercise is a core component of care for patients with PAD and notes that supervised exercise therapy and structured community-based or home-based programs are used for chronic symptomatic PAD. It also states that unstructured advice to simply “go out and walk” has not shown the same evidence for improving walking performance and quality of life.
Checklist Step 10: Ask About Foot Care
PAD can make minor foot injuries harder to heal. Foot care is especially important if you also have diabetes, neuropathy, prior ulcers, foot deformities, or poor vision.
- “Can you examine my feet today?”
- “Do I have wounds, pressure points, skin changes, or reduced pulses?”
- “Should I see a podiatrist?”
- “What foot symptoms should make me call right away?”
The AHA’s 2024 patient messages emphasize that minor wounds can be difficult to heal with PAD and may lead to infection, tissue damage, or amputation in severe cases. They also note that foot exams and ABI testing can help evaluate PAD.
Checklist Step 11: Ask About Leg Pain at Rest
Leg pain with walking that improves with rest can fit claudication. Pain in the foot or leg at rest, especially at night or when lying flat, can be more concerning.
- “Is my pain claudication or rest pain?”
- “Does pain at night suggest poor blood flow?”
- “Should I be evaluated for chronic limb-threatening ischemia?”
- “What should I do if rest pain returns or worsens?”
Tell your doctor if pain is present when you are not walking, if it wakes you from sleep, or if dangling the leg over the bed seems to relieve it.
Checklist Step 12: Ask About Procedures and Revascularization
Some people with PAD need procedures to restore blood flow. These may include angioplasty, stenting, atherectomy, bypass surgery, or other vascular procedures depending on anatomy and severity.
- “Do I need a vascular procedure?”
- “Would a procedure improve symptoms, wound healing, or limb risk?”
- “What are the benefits, risks, and recovery expectations?”
- “What happens if I choose medical therapy and exercise first?”
The ACC’s key points state that in patients with functionally limiting claudication and an inadequate response to guideline-directed medical therapy, including structured exercise, revascularization is a reasonable treatment option to improve walking function and quality of life.
Checklist Step 13: Ask About Follow-Up After a Procedure
PAD procedures require long-term follow-up. Symptoms can return, stents or bypass grafts can narrow, and cardiovascular risk still needs treatment.
- “How often do I need follow-up after the procedure?”
- “Do I need ultrasound or repeat ABI testing?”
- “What symptoms suggest the artery has narrowed again?”
- “Which medicines should I continue long term?”
The ACC’s 2024 guideline summary states that for patients who have undergone revascularization and develop new lower-extremity signs or symptoms, ABI and arterial duplex ultrasound are recommended.
Checklist Step 14: Ask About Medications for Walking Symptoms
Some medicines may help walking distance in selected people with claudication, but they are not right for everyone and do not replace risk-reduction treatment.
- “Is there medication that could improve my walking symptoms?”
- “Am I a candidate for cilostazol?”
- “Are there reasons I should avoid it, such as heart failure?”
- “How will we know if it is helping?”
Ask your clinician to explain the goal of each medication: reducing heart and limb risk, lowering cholesterol, controlling blood pressure, treating diabetes, preventing clots, reducing pain, or improving walking ability.
Checklist Step 15: Ask What to Track at Home
Home tracking can make follow-up more useful. It can also help identify worsening symptoms earlier.
- “Should I track walking distance or time before pain starts?”
- “Should I track foot color, temperature, wounds, or skin changes?”
- “Should I track blood pressure, glucose, or weight?”
- “What changes should make me call before my next visit?”
Useful tracking may include how far you can walk before symptoms start, how long symptoms take to improve with rest, whether pain is in the calf, thigh, buttock, or foot, and whether there are new wounds or color changes.
Checklist Step 16: Ask Which Symptoms Are Urgent
PAD symptoms can change slowly, but some signs need urgent evaluation.
- “What symptoms suggest acute limb ischemia?”
- “What should I do if my foot becomes suddenly cold, pale, blue, numb, or weak?”
- “What if I develop a wound that is not healing?”
- “When should I go to the emergency department?”
Seek urgent care for sudden leg or foot pain, sudden coldness, sudden weakness, numbness, pale or blue color, loss of pulses if known, rapidly worsening symptoms, or a foot wound with spreading redness, drainage, fever, or black tissue.
Home Tools That May Help
Home tools can support PAD care when used with a clinician’s plan. Helpful options may include a walking log, symptom diary, foot mirror, properly fitting shoes, blood pressure monitor, medication organizer, glucose meter or continuous glucose monitor when recommended, smoking cessation tools, and a folder for vascular test results.
A home blood pressure monitor can help track cardiovascular risk. A foot mirror can help people with limited mobility inspect the soles of the feet. Supportive shoes can reduce rubbing and pressure points.
Do not use home tools to delay care for rest pain, wounds, sudden coldness, color change, numbness, weakness, or symptoms that worsen quickly.
Common Mistake: Thinking PAD Is Just Leg Pain
PAD affects blood vessels and can signal higher risk throughout the body. The leg symptoms matter, but so do heart attack, stroke, kidney, diabetes, cholesterol, and blood pressure risk.
Ask your doctor how PAD changes your whole cardiovascular prevention plan.
Treatment should address both walking symptoms and long-term vascular risk.
Common Mistake: Ignoring Symptoms Because They Improve With Rest
Claudication often improves with rest, but that does not mean it should be ignored. Pain that repeatedly appears with walking may be an important PAD symptom.
Track how far you can walk before symptoms start and how long recovery takes.
Tell your clinician if your walking distance is getting shorter.
Common Mistake: Skipping Foot Checks
PAD can make wounds harder to heal. If sensation is reduced from neuropathy or diabetes, foot injuries may go unnoticed.
Ask to remove your socks and shoes during the visit so your clinician can examine skin, pulses, wounds, and pressure points.
Call promptly for new sores, color changes, infection signs, or wounds that do not improve.
Common Mistake: Avoiding Exercise Completely
Leg discomfort can make people stop walking. But for many people with chronic symptomatic PAD, structured exercise is part of treatment.
Ask for a specific program rather than guessing. Supervised exercise therapy may be available and may be covered depending on your health plan and location.
Do not push through severe, sudden, or unusual pain without medical guidance.
Common Mistake: Treating a Procedure as a Cure
Procedures can improve blood flow, symptoms, or wound healing, but they do not remove the underlying tendency toward artery disease.
After revascularization, continued medication, risk-factor control, foot care, exercise, and follow-up remain important.
Ask which medicines and visits continue after the procedure.
When to Talk to a Doctor
Talk to a doctor if you have leg pain, cramping, heaviness, fatigue, numbness, weakness, or buttock, thigh, calf, or foot discomfort during walking that improves with rest.
You should also ask about PAD if you have slow-healing foot or leg wounds, cold feet, color changes, reduced hair growth on the legs, shiny skin, weak pulses, diabetes, smoking history, kidney disease, high blood pressure, high cholesterol, prior heart disease, stroke, or family history of vascular disease.
A clinician may recommend pulse checks, foot exam, ankle-brachial index testing, exercise ABI testing, arterial ultrasound, vascular imaging, cholesterol treatment, antiplatelet therapy, blood pressure treatment, diabetes care, smoking cessation support, structured exercise therapy, podiatry, or vascular specialist referral.
When to Seek Urgent or Emergency Care
Seek urgent care for sudden leg or foot pain, sudden coldness, pale or blue skin, new numbness or weakness, loss of movement, rapidly worsening symptoms, black tissue, or a wound with spreading redness, drainage, fever, or severe pain.
Call emergency services for stroke symptoms, chest pain, severe shortness of breath, fainting, or symptoms that feel life-threatening.
Do not wait for a routine PAD appointment if symptoms suggest sudden loss of blood flow, severe infection, heart attack, stroke, or another emergency.
The Bottom Line
A PAD visit should help you understand whether your symptoms fit peripheral artery disease, how severe the blood-flow problem is, what your heart and stroke risk is, and what treatment plan fits your situation.
Helpful questions include asking about claudication, ABI testing, imaging, severity, heart risk, statins, antiplatelet therapy, blood pressure, diabetes, smoking cessation, structured exercise, foot care, rest pain, procedures, post-procedure follow-up, walking medications, home tracking, and urgent symptoms.
The most common mistakes are thinking PAD is just leg pain, ignoring symptoms because they improve with rest, skipping foot checks, avoiding exercise completely, and treating a procedure as a cure.
Bring this checklist to your next visit and ask your doctor to examine your feet, review your vascular risk factors, and explain which steps can reduce both walking symptoms and long-term heart, stroke, and limb risk.
