BACKGROUND: Long-term cardiovascular and limb outcomes after revascularization for peripheral artery disease and, in particular, prognosis after post-procedure major adverse limb events (MALE) are not well-studied.
OBJECTIVES: This study sought to describe outcomes after peripheral revascularization and assess relationships between post-procedure MALE hospitalization and subsequent events.
METHODS: Patients undergoing peripheral artery revascularization between January 1, 2009, and September 30, 2015, in the Premier Healthcare Database were examined for the co-primary outcomes of interest, composite myocardial infarction (MI) or stroke and composite major amputation or peripheral revascularization. Multivariable adjusted Cox proportional hazards models with post-procedure MALE hospitalization included as a time-dependent covariate were developed to estimate hazard ratios for outcomes.
RESULTS: Among 393,017 revascularized patients followed for a median of 2.7 years (interquartile range: 1.3 to 4.4 years), the cumulative incidence of MI or stroke was 9.8% and that of major amputation or peripheral revascularization was 41.9%. A total of 50,750 patients (12.9%) had at least 1 post-procedure MALE hospitalization. In time-dependent covariate adjusted models, post-procedure MALE hospitalization was associated with greater risk of subsequent MI or stroke (hazard ratio: 1.34; 95% confidence interval: 1.28 to 1.40) and major amputation or peripheral revascularization (hazard ratio: 8.13; 95% confidence interval: 7.96 to 8.29). After peripheral revascularization with or without post-procedure MALE hospitalization, risk of limb events increased rapidly post-procedure and more slowly after the first year, whereas cardiac risk increased steadily during follow-up.
CONCLUSIONS: Revascularized peripheral artery disease patients face earlier limb and later cardiovascular ischemic risk that is heightened among patients with post-procedure MALE hospitalization. Increased provider awareness of these long-term risks may guide efforts to improve post-procedural outcomes.
