What is Peripheral Artery Disease (PAD)?

Peripheral Artery Disease (PAD) is a vascular condition characterized by the narrowing or blockage of arteries that supply blood to the extremities, primarily the legs. It is a type of peripheral vascular disease that results from atherosclerosis, a process in which fatty deposits, cholesterol, and other substances build up in the arterial walls, forming plaques.


What causes PAD and who is at risk?

Peripheral Artery Disease (PAD) is primarily caused by atherosclerosis, a condition characterized by the buildup of fatty deposits, cholesterol, and other substances on the inner walls of arteries. The formation of plaques narrows and restricts blood flow to the extremities, most commonly affecting the legs. Several factors contribute to the development of PAD, and certain individuals are at a higher risk.

Here are key causes and risk factors:

  • Atherosclerosis: The leading cause of PAD is atherosclerosis, the accumulation of plaque in the arteries. Over time, this process can result in the narrowing or blockage of blood vessels.
Risk Factors:
  • Smoking: Tobacco use is a significant risk factor for PAD. Smoking damages the arteries and accelerates the progression of atherosclerosis.
  • Diabetes: Individuals with diabetes are at an increased risk of developing PAD. High blood sugar levels can contribute to arterial damage.
  • Age: PAD becomes more prevalent with age. The risk increases significantly in individuals over the age of 50.
  • High Blood Pressure (Hypertension): Elevated blood pressure can contribute to the hardening and narrowing of arteries, increasing the risk of PAD.
  • High Cholesterol: Elevated levels of LDL cholesterol (low-density lipoprotein) can contribute to the formation of arterial plaques.
  • Genetics (Family History): A family history of PAD or atherosclerosis increases the likelihood of developing the condition.
  • Obesity: Excess body weight can contribute to the development and progression of atherosclerosis.
  • Inactive Lifestyle: Lack of physical activity is a significant risk factor. Regular exercise promotes cardiovascular health and helps prevent PAD.
  • Race and Ethnicity: African Americans have a higher risk of PAD than Caucasians. Other ethnic groups may also have varying levels of risk.
  • Gender: Men are generally at a higher risk of PAD than women, especially in younger age groups. However, the risk becomes more equal in older age groups.
  • Other Cardiovascular Diseases: Individuals with a history of coronary artery disease or cerebrovascular disease are at an increased risk of PAD.

Additional Risk Factors:

  • Inflammatory Conditions: Conditions that cause inflammation, such as rheumatoid arthritis, may increase the risk of PAD.
  • Certain Medications: Some medications may contribute to vascular issues and increase the risk of PAD. It's important to note that while these factors contribute to the risk of PAD, the presence of one or more risk factors does not guarantee that an individual will develop the condition. Individuals with risk factors or symptoms should consult with healthcare professionals for proper evaluation and guidance.

What are the symptoms of PAD?

Peripheral Artery Disease (PAD) can manifest with a variety of symptoms, primarily due to reduced blood flow to the extremities, most commonly the legs. The severity of symptoms can vary, and some individuals with PAD may not experience noticeable symptoms. Common symptoms of PAD include:

  • Claudication: Pain, cramping, or fatigue in the muscles of the legs, especially during physical activity or walking. This discomfort typically improves with rest and worsens again with activity.
  • Numbness or Weakness: A sensation of numbness or weakness in the legs may occur, affecting the ability to walk or perform daily activities.
  • Wounds or sores may take longer to heal: Wounds does not heal due to decreased blood supply and required intervention.
  • Coldness in the Extremities: The affected leg or foot may feel cooler than the other, and the skin may appear pale or bluish.
  • Changes in Skin: The skin on the legs or feet may change color, becoming shiny, dry, or discolored.
  • Hair Loss on Legs: Reduced blood flow may lead to decreased hair growth on the legs or feet.
  • Poor Nail Growth: Slowed or poor nail growth may occur due to decreased blood circulation.
  • Erectile Dysfunction (in Men): Reduced blood flow to the pelvic area may contribute to erectile dysfunction in men.
  • Pain or Discomfort at Rest: In advanced cases, individuals may experience pain or discomfort in the legs even at rest. This is known as rest pain and is a sign of severe PAD.

It's important to note that some individuals with PAD may not experience classic symptoms, a condition referred to as asymptomatic PAD. Additionally, symptoms of PAD can be similar to other conditions, so a comprehensive evaluation by a healthcare professional is essential for an accurate diagnosis.

How is PAD diagnosed and treated?

Peripheral Artery Disease (PAD) is diagnosed through a combination of medical history assessment, physical examination, and various diagnostic tests. Once diagnosed, treatment aims to manage symptoms, improve blood flow, and reduce the risk of complications. Here's an overview of how PAD is diagnosed and treated:


  • Medical History and Physical Examination: The healthcare provider will inquire about symptoms, risk factors, and overall health. A physical examination may involve checking pulses, assessing for signs of arterial disease, and evaluating the skin and nails.
  • Ankle-Brachial Index (ABI): This non-invasive test compares the blood pressure in the ankles to that in the arms. A lower ABI suggests reduced blood flow to the legs.
  • Doppler Ultrasound: This imaging test uses sound waves to create images of blood flow in the arteries. It can help identify blockages or narrowing in the arteries.
  • Segmental Pressure Measurements: Blood pressure measurements are taken at different levels of the legs to assess blood flow and identify areas of blockage.
  • Angiography: Invasive procedures, such as angiography, involve injecting a contrast dye into the arteries to obtain X-ray images. This provides detailed information about the location and severity of arterial blockages.
  • Magnetic Resonance Angiography (MRA) or Computed Tomography Angiography (CTA): These non-invasive imaging techniques use advanced imaging technology to visualize blood vessels and identify blockages.


Lifestyle Modifications:
  • Smoking Cessation:Quitting smoking is crucial to slow the progression of PAD.
  • Exercise:Regular physical activity can improve circulation. A supervised exercise program may be recommended.
  • Antiplatelet Medications: Aspirin or clopidogrel may be prescribed to reduce the risk of blood clots.
  • Cholesterol-Lowering Medications: Statins may be used to manage cholesterol levels and slow the progression of atherosclerosis.
  • Blood Pressure Medications: Controlling hypertension is important for managing PAD.
Angioplasty and Stenting:
  • In cases of significant arterial blockage, angioplasty may be performed. A catheter with a balloon is used to open the blocked artery, and a stent may be inserted to keep the artery open.
Bypass Surgery:
  • In severe cases, bypass surgery may be recommended. This involves creating a new route for blood flow using a graft.
Supervised Exercise Programs:
  • Structured exercise programs, often supervised by healthcare professionals, can improve walking distance and reduce symptoms.
Wound Care:
  • For individuals with ulcers or wounds, proper wound care is essential to prevent infection and promote healing.
Risk Factor Management:
  • Addressing and managing underlying risk factors, such as diabetes, hypertension, and obesity, is crucial.
Regular Follow-up:
  • Ongoing monitoring and regular follow-up with healthcare providers are important to assess the effectiveness of treatment and make adjustments as needed. Treatment for PAD is individualized based on the severity of the condition, the presence of symptoms, and other health considerations. Patients with PAD should actively participate in their care by adopting a heart-healthy lifestyle and adhering to the prescribed treatment plan. Early diagnosis and management of PAD are essential to prevent complications and improve overall cardiovascular health.

How does PAD affect wound healing?

Peripheral Artery Disease (PAD) can significantly impact wound healing, particularly in the lower extremities, due to reduced blood flow to the affected areas. In PAD, the arteries that supply blood to the legs and feet become narrowed or blocked, leading to insufficient oxygen and nutrient delivery to the tissues. This compromised blood flow can impair the body's ability to heal wounds efficiently.
