Two-Year Life Expectancy in Patients With Critical Limb Ischemia

Abstract Objectives This study sought to estimate the 2-year life expectancy (2YLE) (estimated survival rate >50% at 2 years) in patients with critical limb ischemia (CLI) using the risk score based on predictors of all-cause mortality within 2 years. Background It has been reported that 2YLE is...

Zusammenfassung:	Abstract Objectives This study sought to estimate the 2-year life expectancy (2YLE) (estimated survival rate >50% at 2 years) in patients with critical limb ischemia (CLI) using the risk score based on predictors of all-cause mortality within 2 years. Background It has been reported that 2YLE is one of the important factors in the decision making of the revascularization strategy. However, little is known about the probability and the prognostic factors of a 2YLE. Method This study was performed as a multicenter retrospective analysis. Between March 2004 and December 2011, 995 CLI patients with follow-up period >730 days undergoing endovascular therapy (EVT) were identified and analyzed. Results Within 2 years, 412 patients (41%) died, and a cardiovascular cause accounted for 47% of deaths. On multivariate analysis, the independent prognostic factors were age 65 to 79 years (odds ratio [OR]: 1.9), 80 years of age or older (OR: 3.7), body mass index (BMI) 18.0 to 19.9 kg/m2 (OR: 1.5), BMI
