September is Peripheral Artery Disease (PAD) Awareness Month, and a time dedicated to raising awareness through the Save a Leg, Save a Life (SALSAL) Foundation’s White Sock Campaign. The goal is to help educate the physician and patient community about PAD – a common, yet serious cardiovascular condition that can result in devastating consequences including heart attack, stroke, amputation, and early death if left untreated.1
WHAT IS PAD?
- PAD occurs when arteries in the legs become narrowed or blocked by plaque build-up, reducing blood flow to the limbs.
WHO IS AT RISK OF PAD?
- Peripheral artery disease, or PAD, affects at least 12 million people in the US2 and is found most commonly in people over age 50 with a history of smoking, diabetes, high blood pressure or heart disease.3-6
WHAT ARE THE SYMPTOMS OF PAD
- Despite its prevalence, PAD is historically difficult to diagnose and treat as symptoms are often ignored, masked or confused with the typical aches and pains of aging.3,7-8 Symptoms may include:
- Fatigue in the leg muscles (buttocks, thigh or calf) that occurs during activities such as walking or climbing stairs.
- Pain in the legs and/or feet that disturbs sleep.
- Sores or Wounds on toes, feet or legs that heal slowly, poorly or not at all.
- Color Changes on the skin of the feet, including paleness or blueness.
- Lower Temperature in one leg compared with the other leg.
- Poor Nail Growth and decreased hair growth on toes and legs.
- As a result, nearly 50 percent of patients with late-stage PAD are left untreated each year, placing them at greater risk of undergoing an amputation.11
DID YOU KNOW?
- PAD affects at least 12 million people in the US.2
- About 95% of PAD patients have at least one other chronic disease, such as diabetes, heart disease, or high blood pressure.12
- Because this disease is not limited to the legs, patients with PAD are also at greater risk of future heart attack and stroke.9,10
- Up to 50% have unrecognized or masked symptoms and may progress directly to severe disease.12,13
- Inhaling smoke damages your blood cells and function of your blood vessels, causing plaque to build up in your arteries. Smoker have up to 4 times greater risk of PAD.3,4
- Poor glycemic control and long-term use of insulin can lead to PAD. Diabetics have up to 4 times greater risk of PAD and up to 5 times greater risk of amputation. 3,4,5,13
- Elevated blood pressure (BP) raises the risk of developing plaque in the arteries. High BP is found in more than 65% of PAD patients.14,15
- Excess cholesterol and fat in your blood creates plaque in arteries, reducing or blocking blood flow to your heart, brain or limbs. It is found in more than 60% of PAD patients.15
- Aging plays a role in your risk of PAD. More than 1 in 10 people over age 65 have PAD.4,6,16
