Peripheral Artery Disease

Peripheral Arterial Disease (P.A.D.) is a narrowing of the arteries outside the heart that causes diminished blood flow.

Prevalence of P.A.D.

  • P.A.D. affects 8-12 million people in the United States
  • One in every 20 Americans over the age of 50 has P.A.D.
  • One in every 3 persons with Diabetes has P.A.D.

Risk Factors for P.A.D.

  • Tobacco use – Risk is four times greater for developing P.A.D.
  • Hypertension (high blood pressure)
  • Anyone older than 50
  • African Americans are twice as likely to have P.A.D.
  • Personal history of vascular disease, heart attack or stroke risk is 3 times greater for developing P.A.D.

Early Signs and Symptoms of P.A.D.

  • Claudication – fatigue or cramping in leg muscles that occurs while 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 in the skin on the feet, including paleness or blueness
  • Poor nail growth and decreased hair growth on toes and legs

The STPH SensiLase® System provides reliable, early and accurate detection of P.A.D. – even in patients with diabetes – by conducting rapid, noninvasive vascular assessments. The professional STPH wound care team performs two tests with the SensiLase® System:

  • Skin Perfusion Pressure to assess the very small vessels (microcirculation)
  • Pulse Volume Recording to assess the large arteries (macrocirculation)

Together, these tests quickly provide information about whether the blood flow in your legs, feet, toes or fingers is decreased or absent due to blockage or damage to your vascular system. This is very important, as small vessels or arteries that have become blocked or damaged may be the cause of wounds healing abnormally.

In addition to wound care, these results can be used to assist physicians in diagnosing any circulatory problems, such as peripheral artery disease (P.A.D.), and guide them in prescribing the most appropriate treatment plan for you.
