Symptom Summary

Detecting & Treating PAD

Detecting & Treating PAD

Peripheral arterial disease (PAD) may be asymptomatic or present with a variety of signs and symptoms of extremity ischemia. Patients in the early stages of PAD often do not report symptoms or mistake them for normal signs of aging. Detection of asymptomatic PAD is important as it may also identify patients at increased risk of atherosclerosis in other arterial beds. These patients can benefit from medical therapies and lifestyle changes that reduce their risk for PAD progression and myocardial infarction (MI), stroke, and death.1

Risk Factors

Risk factors for PAD are similar to those that promote the development of coronary heart disease. For PAD, markers of inflammation and tobacco smoking are more influential while total cholesterol and body mass are less important though relevant. Other important predictors for PAD are age, high-sensitivity C-reactive protein, systolic blood pressure, socioeconomic status, and lipoprotein(a).2 Diabetes mellitus is a powerful predictor of PAD and has been associated with increased rates of Critical Limb Ischemia (CLI) and amputation.3

Age
1 in 20 people ages 50+ are estimated to be affected by PAD.4

Age

High cholesterol
The risk of PAD increases 5-10% with every 10 mg/dL increase in total cholesterol levels.5

High cholesterol

High blood pressure
Can eventually damage artery walls and lead to disease.6

High blood pressure

diabetes
Type 2 diabetes can make you 4 times more likely to develop PAD.7

Diabetes

smoking cessation
Tobacco use increases your risk of developing PAD up to 4 times.8

Tobacco use

Kidney disease
Individuals with low kidney function are twice as likely to have PAD.9

Family History
Having family members with PAD can increase your risk.10

Ethnicity
African Americans and Hispanics are at the highest risk for PAD.11

Screening Guidelines

The American College of Cardiology/American Heart Association (ACC/AHA) guidelines on PAD have identified the following groups with a higher prevalence of PAD where screening may be appropriate12:

  • Age ≥65 years
  • Age 50 to 64 years with risk factors for atherosclerosis (e.g., diabetes mellitus, history of smoking, hyperlipidemia, hypertension) or family history of PAD
  • Age <50 with diabetes mellitus and one additional risk factor for atherosclerosis
  • Known atherosclerosis at other sites (e.g., coronary, carotid, renal artery disease)
  • A history of claudication, other non-joint related exertional lower extremity symptoms, impaired walking function, and/or ischemic rest pain
  • Physical presentation with abnormal lower extremity pulses, vascular bruit, non-healing lower extremity wound or gangrene, or other suggestive physical findings (e.g., elevation pallor/dependent rubor)

Diagnosis of PAD

Patients at risk for PAD should undergo a comprehensive vascular examination and PAD screening should always include questions related to a history of walking impairment, extremity pain that might be due to ischemia, and the presence of non-healing wounds. Since the presentation of PAD can vary, patients with risk factors for PAD who report no or few symptoms should be asked about functional capacity and decline in activity over time, including exertional non-joint related pain.12

For many patients, a history of risk factors or symptoms of PAD, in combination with physical examination findings, is sufficient to establish a diagnosis of PAD. Patients with atypical symptoms or abnormal physical findings require confirmation with an Ankle-Brachial Index (ABI) to establish the diagnosis of PAD. The ACC/AHA guidelines recommend for patients with a history or physical examination findings suggestive of PAD, a resting ABI, with or without segmental pressures and waveforms, is recommended to establish the diagnosis.12

Clinical classification of chronic lower extremity PAD is based upon the severity of symptoms and differentiates the advanced signs of PAD, tissue loss, such as ulceration and gangrene. The later stages of the disease, ischemic rest pain and tissue loss, are considered critical limb ischemia (CLI).13

Critical Limb Ischemia

Critical limb ischemia presents as ischemic rest pain with or without tissue loss, such as skin ulceration, diabetic ulcer or gangrene. CLI is estimated to occur in 1 to 2 percent of patients with symptomatic PAD.14

Patients with CLI are at risk for limb loss with an associated 1-year limb loss rate of 20% and a 1-year mortality rate of 20%.15 Estimates show that 33% of CLI patients with an amputation will have a contralateral amputation within 3 to 5 years.16 It has been reported in a retrospective analysis, however, that 54% of CLI patients had no vascular procedures performed in the year before major lower extremity amputation.17 Early intervention with the right network is key to reduce the chances of amputation.

Limb Salvage Programs

A multidisciplinary and integrated approach involving the primary care provider, podiatrist and/or wound care, interventional specialist, and other hospital resources provides optimal medical and surgical care. PAD is a manageable condition. When recognized early and appropriately managed by a limb salvage team, complications that can lead to amputation can be minimized.

Early Intervention With The Right Team Is Key

The key physicians on a limb salvage team are determined by the pathology and stage of the disease. The core team includes clinicians caring for the foot and wounds (podiatrist and/or wound care) along with clinicians focused on the vascular integrity of the lower extremity (interventional specialist). Additional participants in a comprehensive care model may include internal medicine, endocrinology, infectious disease, physical therapy, plastic surgery, nursing, emergency medicine and prosthetics.18 Multiple global studies have shown the effectiveness of a multidisciplinary team in reducing ulceration rates and preventing amputations related to diabetic foot conditions, including PAD.19

Economics Of PAD

The total cost of amputation goes far beyond the operating room.

At 5 years, a purely endovascular approach was projected to have a cost savings of approximately 21% versus amputation.*20 Factors influencing the total cost of amputation include procedural costs, nursing home and rehabilitation costs, home healthcare, and medical equipment such as prosthetics and wheelchairs.21

Quality Of Life

People with limb loss due to CLI experience significantly lower health status, high rates of mortality, and increased risk for cardiovascular disease, obesity, joint and bone issues, plus high rates of depression, and emotional distress.22-27

Studies estimate the 5-year mortality rate for people with an amputation, due to PAD, to be between 50% and 74%, which is higher than colorectal cancer, breast cancer and coronary artery disease (CAD).28-29
