Screening for peripheral arterial disease.

Peripheral arterial disease (PAD) is an age-dependent condition that limits ambulation and compromises quality of life in an estimated two million Americans. Early detection and treatment is essential for minimizing the signs and symptoms of PAD. Using a methodology developed by the National Council on the Aging, a noninvasive screening program was conducted for this disease in a population of 1,092 elderly ambulatory Rhode Island residents. Possible PAD was detected in 17.7% of the subjects, while 42% were identified as being at high risk for the disease.
