Primary Outcome Measures:
  • Change from baseline in Health Status at 6 months [ Time Frame: Baseline (pre procedure), 6 months ] [ Designated as safety issue: No ]
    Health Status will be measured at baseline and six months following the procedure

Estimated Enrollment: 450
Study Start Date: May 2011
Estimated Study Completion Date: September 2014
Estimated Primary Completion Date: September 2014 (Final data collection date for primary outcome measure)
Patients treated for PAD medically or with exercise therapy

Detailed Description:

Using electronic medical records, a registry of patients undergoing lower extremity revascularization therapy will be identified. Chart reviews with be done by an expert panel.

The prospective cohort study will ask participants to complete health status surveys before they begin therapy for PAD and again 6 months later.
