Asymptomatic Peripheral Arterial Disease Is Independently Associated With Impaired Lower Extremity Functioning

Abstract
Background—We report the implications of asymptomatic lower extremity peripheral arterial disease (PAD) for lower extremity functioning among participants in the Women’s Health and Aging Study, an observational study of disabled women ≥65 years of age living in and around Baltimore. Methods and Results—The ankle brachial index (ABI) and measures of upper and lower extremity functioning were measured among study participants. Of 933 women with ABI ≤1.50, 328 (35%) had an ABI Conclusions—Asymptomatic PAD is common and is independently associated with impaired lower extremity functioning. In addition to preventing cardiovascular morbidity and death, further study is warranted to identify effective interventions to improve functioning among the growing number of men and women with asymptomatic PAD.
