Definition

 

Peripheral artery disease is a common disorder that usually affects men over age 50.

People are at higher risk if they have a history of:

  • Abnormal cholesterol

  • Diabetes

  • Heart disease (coronary artery disease)

  • High blood pressure (hypertension)

  • Kidney disease involving hemodialysis

  • Smoking

  • Stroke (cerebrovascular disease)

indication of blocked arteries

normal: ankle is slightly higher pressure than at the elbow (normally positive)

1.3 to .91 = normal (ankle > arm)

0.9  to .4 = mild (ankle bp less than arms)

0.4 to 0   = severe (ankle BP much lower than arms)

Term
