Predicting long-term prognosis in stable peripheral artery disease with baseline functional capacity estimated by the Duke Activity Status Index.

ABSTRACT:

Background

The ability of a simple self-assessment tool for estimated functional capacity to predict long-term prognosis in patients with established peripheral artery disease (PAD) is unknown. We investigate whether subjective measurement of functional capacity estimated by using the Duke Activity Status Index (DASI) questionnaire predicts long-term prognosis in patients with established PAD.

Methods

We administered the DASI questionnaire to 771 stable patients with established PAD who underwent elective diagnostic coronary angiography with 5-year follow-up all-cause mortality.

Results

Two hundred ten patients (27%) died over a 5-year follow-up. The lowest DASI score was associated with a 3.2-fold increased risk of 5-year all-cause mortality (unadjusted hazard ratio
