Art Assist Device for Critical Limb Ischemia (ArtAssist Trial)

In this clinical research study the investigators will test the efficacy of an innovative, non-invasive methodology to reduce mortality and lower limb loss among high-risk medically-underserved patients with cardiovascular disease in North Philadelphia. Patients with cardiovascular disease and recent lower limb amputation will be treated with an intermittent compression device on the remaining lower limb to prevent dual amputation. The study hypothesis is that the study intervention will protect against further lower limb-loss/death and reduce cardiovascular mortality in these patients (one year effect against limb-loss/death). This study may result in better secondary prevention strategies for disadvantaged urban populations as well as the general population.
