Predictors of mortality in patients with lower extremity peripheral arterial disease: 5-year follow-up.

BACKGROUND: Peripheral arterial disease (PAD) is associated with increased mortality. Lower extremity (LE) revascularization improves symptoms, but less is known about long-term survival benefits of LE arterial revascularization. METHODS: Two hundred and eighty-three patients with an ankle brachial index (ABI) or=65 years (HR 2.42 [95% CI 1.52-3.85], P < 0.001), history of coronary artery disease (HR 1.67 [95% CI 1.13-2.46], P = 0.010), chronic kidney disease (HR 1.75 [95% CI 1.15-2.67], P = 0.010), and an ABI
