Executive Summary

Peripheral artery disease (PAD) is a common but often underdiagnosed condition affecting millions of people worldwide. It occurs when arteries in the legs become narrowed or blocked by atherosclerotic plaque, reducing blood flow to the muscles and tissues. PAD is not just a leg problem—it is a marker of systemic atherosclerosis that significantly increases the risk of heart attack, stroke, and cardiovascular death.

The most common symptom of PAD is claudication—leg pain, cramping, or fatigue with walking that resolves with rest. However, many people with PAD have no symptoms or dismiss leg discomfort as a normal part of aging, leaving the condition undiagnosed and untreated. This is concerning because PAD indicates widespread vascular disease that requires aggressive management.

At Healers Clinic Dubai, we recognize that PAD requires comprehensive, individualized care. Our integrative approach combines evidence-based conventional treatments with lifestyle modification, nutritional support, smoking cessation programs, and complementary therapies to address all aspects of this systemic disease. We focus not only on relieving leg symptoms but also on preventing heart attacks, strokes, and other cardiovascular events.

This comprehensive guide provides the knowledge needed to understand PAD, recognize its symptoms, seek appropriate evaluation, and implement effective treatment strategies. Whether you have been diagnosed with PAD, have risk factors for the disease, or are caring for someone with PAD, this guide will help you navigate this important health condition.

Understanding Peripheral Artery Disease - Comprehensive Overview

What Is Peripheral Artery Disease

Peripheral artery disease is a manifestation of atherosclerosis in the arteries outside the heart and brain. While PAD most commonly affects the arteries supplying the legs, it can also affect arteries in the arms, kidneys, abdomen, and neck. The term “peripheral” refers to the peripheral (outer) regions of the body, as opposed to the central circulation (heart and brain).

Atherosclerosis is the underlying process in PAD, the same disease that causes coronary artery disease (heart attacks) and cerebrovascular disease (strokes). Atherosclerosis develops when LDL (bad) cholesterol enters the artery wall, becomes oxidized, and triggers an inflammatory response. This leads to the formation of fatty streaks, which progress to atherosclerotic plaques consisting of a core of lipid and inflammatory cells capped by fibrous tissue.

As plaques grow in the leg arteries, they narrow the arterial lumen, restricting blood flow to the muscles and tissues below the blockage. During rest, the reduced blood flow may be sufficient for the metabolic demands of the tissues. However, during walking, when muscles require increased blood flow, the narrowed arteries cannot deliver enough blood, leading to the characteristic symptoms of claudication.

PAD severity is classified based on symptoms and hemodynamic findings. The Rutherford classification ranges from Category 0 (asymptomatic) through Category 6 (severe ischemia with tissue loss). The Fontaine classification similarly ranges from Stage I (asymptomatic) through Stage IV (ulceration/gangrene).

The Global and Dubai-Specific Context

PAD affects approximately 200 million people worldwide, with prevalence increasing with age. In developed countries, approximately 5-10% of people over age 60 have PAD, and the prevalence is rising as populations age and risk factors become more common.

In Dubai and the UAE, the high prevalence of diabetes, hypertension, obesity, and metabolic syndrome contributes to PAD risk. Smoking rates in some segments of the population are also significant. The professional culture with long hours of sitting or standing may affect vascular health.

PAD is often underdiagnosed. Studies suggest that only about 25% of people with PAD are aware of their condition. Many dismiss leg discomfort as a normal part of aging or attribute it to arthritis or other conditions.

The significance of PAD extends beyond leg symptoms. People with PAD have a 2-3 fold increased risk of heart attack and stroke compared to those without PAD. PAD is considered a coronary heart disease risk equivalent, meaning that having PAD confers cardiovascular risk similar to someone who has already had a heart attack.

The Science Behind Peripheral Artery Disease

Atherosclerosis in the Leg Arteries

Atherosclerosis affecting the leg arteries has the same underlying mechanisms as atherosclerosis in the coronary and cerebral arteries. However, the clinical presentation differs because the symptoms (claudication) are related to physical exertion and the metabolic demands of leg muscles.

The most common sites of atherosclerosis in the legs are the superficial femoral artery (in the thigh), the popliteal artery (behind the knee), and the tibial arteries (in the calf). Aortoiliac disease (affecting the aorta and iliac arteries in the pelvis) is also common, particularly in smokers.

When blood flow is restricted by arterial narrowing, the leg muscles receive less oxygen during exercise. The accumulation of metabolic waste products (lactic acid, hydrogen ions) during anaerobic metabolism causes the muscle pain and cramping characteristic of claudication. Rest allows these waste products to be cleared and oxygen supply to catch up with demand, relieving the pain.

With severe disease, even rest may not provide adequate blood flow, leading to rest pain—typically in the feet, worse at night when legs are elevated. Severe PAD can lead to tissue damage, non-healing wounds, and gangrene requiring amputation.

Risk Factors for PAD

The risk factors for PAD are essentially the same as for coronary artery disease.

Smoking is the most important modifiable risk factor for PAD. Smokers are 2-4 times more likely to develop PAD than non-smokers, and smoking accelerates disease progression.

Diabetes dramatically increases PAD risk. People with diabetes are 2-4 times more likely to develop PAD, and the disease tends to be more severe and progress more rapidly.

Hypertension (high blood pressure) damages artery walls and accelerates atherosclerosis.

High LDL cholesterol and low HDL cholesterol contribute to plaque formation.

Age is a major risk factor; PAD becomes more common after age 50 and increases significantly after age 70.

Family history of atherosclerosis increases risk, likely through both genetic and shared lifestyle factors.

Obesity, physical inactivity, and metabolic syndrome all contribute to PAD risk.

Chronic kidney disease is associated with accelerated atherosclerosis and increased PAD risk.

Signs, Symptoms, and Warning Signs

Classic Symptom: Claudication

The most characteristic symptom of PAD is claudication—a cramp-like, aching, or burning pain in the leg muscles (typically the calf, but can affect the thigh or buttock) that occurs with walking and resolves with rest.

Key characteristics of claudication include:

Onset with a consistent amount of walking distance (the “claudication distance”), which may shorten as PAD progresses.

Relief within 1-5 minutes of stopping walking.

Reproducible occurrence with the same level of exertion.

Location below the level of arterial blockage (calf involvement suggests femoral/popliteal disease; buttock/thigh claudication suggests aortoiliac disease).

Other Symptoms

Leg fatigue or heaviness, particularly with exertion.

Weakness or numbness in the legs.

Coldness in the affected leg compared to the other leg.

Skin changes including thin, shiny skin; loss of hair on the legs and feet; thickened or discolored toenails.

Muscle atrophy (wasting) in severe cases.

Asymptomatic PAD

Many people with PAD have no symptoms, a condition sometimes called asymptomatic peripheral artery disease. This is particularly common in women, in people with diabetes, and in those who are less active. Asymptomatic PAD still confers increased cardiovascular risk and warrants treatment.

Critical Limb Ischemia

Critical limb ischemia (CLI) is the most severe form of PAD, characterized by chronic rest pain lasting more than 2 weeks, non-healing wounds or ulcers, or gangrene. CLI indicates severely compromised blood flow and requires urgent intervention to prevent amputation.

Warning Signs Requiring Immediate Care

Sudden severe leg pain, pallor, pulselessness, paralysis, and paresthesia may indicate acute limb ischemia—a medical emergency.

Wounds or ulcers that are not healing, particularly on the feet.

Signs of infection in a foot wound (increasing pain, redness, warmth, pus, fever).

Increasing pain despite rest.

Diagnosis and Assessment Methods

Clinical Evaluation

History and physical examination are the foundation of PAD diagnosis.

History should include symptoms (claudication characteristics), risk factors, and functional limitation.

Physical examination may reveal diminished or absent pulses in the legs and feet, cool skin temperature, hair loss on legs and feet, thin shiny skin, thickened nails, and pallor on elevation with rubor (redness) on dependency.

Ankle-Brachial Index (ABI)

The ABI is a simple, non-invasive test that compares blood pressure in the ankles to blood pressure in the arms.

A normal ABI is 0.90-1.30. ABI less than 0.90 indicates arterial disease: 0.90-0.71 mild, 0.70-0.41 moderate, and less than 0.40 severe disease.

ABI greater than 1.30 may indicate non-compressible calcified arteries, common in diabetics and those with kidney disease. In such cases, other tests are needed.

Imaging Studies

Duplex ultrasound combines traditional ultrasound with Doppler to visualize arteries and assess blood flow. It can localize blockages and assess severity.

CT angiography (CTA) provides detailed images of the arterial tree using CT scanning with contrast dye.

MR angiography (MRA) uses MRI to visualize arteries, avoiding radiation and some risks of contrast dye.

Conventional angiography (invasive catheter-based imaging) remains the gold standard and allows intervention (angioplasty, stenting) during the same procedure.

Functional Assessment

Treadmill exercise testing can objectively measure claudication distance and assess improvement with treatment.

Walking distance tests (6-minute walk test) assess functional capacity.

Conventional Treatment Approaches

Medical Therapy

Antiplatelet therapy (aspirin or clopidogrel) reduces the risk of heart attack, stroke, and cardiovascular death in PAD patients.

Statin therapy (high-intensity statins) stabilizes plaque, reduces LDL cholesterol, and improves symptoms and outcomes.

Cilostazol improves walking distance in patients with claudication (not recommended in patients with heart failure).

ACE inhibitors or ARBs may improve walking distance and cardiovascular outcomes.

Exercise Therapy

Supervised exercise training is highly effective for improving claudication symptoms. Programs typically involve walking on a treadmill for 30-50 minutes, 3 times per week, for 12 weeks or more.

Home-based exercise programs can also be effective with proper guidance.

The improvement occurs through multiple mechanisms: development of collateral circulation, improved endothelial function, more efficient oxygen extraction, and improved walking economy.

Revascularization Procedures

Endovascular (minimally invasive) procedures include:

Angioplasty: Balloon inflation to open narrowed arteries.

Stenting: Placement of metal scaffolds to keep arteries open.

Atherectomy: Removal of plaque using specialized devices.

Bypass surgery creates a new route for blood flow around the blocked artery, using either the patient’s own vein (autologous bypass) or a synthetic graft.

Revascularization is indicated for patients with lifestyle-limiting claudication despite optimal medical therapy and exercise, and for those with critical limb ischemia.

Wound Care

For patients with ulcers or gangrene, specialized wound care is essential.

Debridement (removal of dead tissue) promotes healing.

Infection control with antibiotics when needed.

Offloading pressure from the affected area.

Advanced wound therapies including growth factors and skin grafts for non-healing wounds.

Smoking Cessation

Smoking cessation is the single most important intervention for slowing PAD progression. All PAD patients who smoke should receive intensive support for quitting.
