What are the signs and symptoms of peripheral artery disease (PVD)?
Approximately half of people with peripheral artery disease do not experience any symptoms. For patients with symptoms, the most common symptoms are intermittent claudication and rest pain.
- Intermittent claudication refers to arm or leg pain or cramping in the arms or legs that occurs with exercise and goes away with rest. The severity and location of the pain of intermittent claudication vary depending upon the location and extent of blockage of the involved artery. The most common location of intermittent claudication is the calf muscle of the leg, leading to calf or leg pain while walking. The pain in the calf muscle occurs only during exercise such as walking, and the pain steadily increases with continued walking until the patient has to stop due to intolerable pain. Then the pain quickly subsides during rest. Intermittent claudication can affect one or both legs.
- Rest pain in the legs occurs when the artery occlusion is so critical that there is not enough blood and oxygen supply to the legs even at rest and represents a more serious form of the condition. The pain typically affects the feet, is usually severe, and occurs at night when the patient is lying down, face up.
Other symptoms and signs of peripheral artery disease include:
- Numbness of the legs or feet
- Weakness and atrophy (diminished size and strength) of the calf muscle
- A feeling of coldness in the legs or feet
- Changes in color of the feet; feet turn pale when they are elevated, and turn dusky red in dependent position
- Hair loss over the top of the feet and thickening of the toenails
- Poor wound healing in the legs or feet
- Painful ulcers and/or gangrene in areas of the feet where blood supply is lost; typically in the toes
Who is at risk for peripheral artery disease (PVD)?
Peripheral artery disease (or peripheral arterial disease) that affects approximately 10 million adults in the U.S. About 5% of people over the age of 50 are believed to suffer from peripheral artery disease. Peripheral artery disease is slightly more common in men than in women and most often occurs in older persons (over the age of 50). The known risk factors for peripheral artery disease are those that predispose to the development of atherosclerosis. Risk factors for peripheral artery disease include:
- High blood levels of the "bad" LDL cholesterol and triglycerides
- Low blood levels of the "good" HDL cholesterol
- Cigarette smoking
- Diabetes mellitus (both type 1 and type 2 diabetes)
- High blood pressure (hypertension) or a family history of hypertension
- A family history of atherosclerotic disease
- Chronic renal failure
- Overweight or obesity
- Physical inactivity
In peripheral artery disease, the risk factors are additive, so that a person with a combination of two risk factors -- diabetes and smoking, for example -- has an increased likelihood of developing more severe peripheral artery disease than a person with only one risk factor.
