Understanding Peripheral Artery Disease

The most common type of peripheral vascular disease (PVD) is peripheral artery disease (PAD). Like the blood vessels of the heart (coronary arteries), your peripheral arteries (blood vessels outside the heart) also may develop atherosclerosis. Over time, the plaque buildup narrows the artery, causing increased pressure in the blood vessel. Eventually, the inside of the artery narrows so much that it restricts blood flow and less oxygen is delivered to the tissues, causing a condition called ischemia, an inadequate supply of blood that causes tissue damage.

If a fragment of this plaque from any part of the body breaks loose and clogs one of the arteries supplying the heart itself, the result is a heart attack. If a fragment breaks and blocks an artery going to the brain, a stroke will result. Narrowing of the arteries that supply the kidneys with blood can cause high blood pressure and kidney failure. Any tissue that does not have an adequate supply of blood and oxygen will, over time, become permanently damaged and die. It is critical to diagnose and treat peripheral vascular diseases before it becomes a more serious problem.

In the early stages of PAD, symptoms include cramping and pain in the legs and buttocks, indicating poor circulation in the legs. Other common symptoms include fatigue, heaviness and discomfort during exercise or activity. These symptoms generally go away when the activity stops or you are resting. This is called “intermittent claudication.”

These are early warning signs. If left undiagnosed and untreated, the symptoms of severe PAD intensify:

  • Leg pain that does not go away when you stop exercising
  • Foot or toe wounds that don’t heal or heal very slowly
  • A decrease in the temperature of your lower leg or foot, particularly compared to the other leg or the rest of your body.

What are the Risk Factors of Peripheral Artery Disease?

The most common type of peripheral vascular disease (PVD) is peripheral artery disease (PAD), which affects about 8 million Americans. Atherosclerosis can start as early as the age of 20, and becomes more common as one gets older. By age 65, about 12 to 20 percent of the population has some degree of vascular disease. The exact cause is unknown, but several risk factors are known to accelerate the formation of fatty deposits, or plaque, in the arteries:

  • Smoking
  • Family history of vascular disease, angina, heart attacks or stroke
  • Being overweight
  • An unhealthy diet
  • Lack of exercise
  • Diabetes
  • Being male
  • High blood pressure
  • High cholesterol levels
  • Stress

Early diagnosis is critical, as people with PAD have a four to five times higher risk of having a heart attack or stroke. Unfortunately, PAD often goes undiagnosed as symptoms are often mistaken for something else.
