Abstract

BACKGROUND: The long-term effect of bariatric surgery on cardiovascular outcomes in the elderly population is not well studied.

OBJECTIVES: The aim of this study was to evaluate the association between bariatric surgery and long-term cardiovascular outcomes in the Medicare population.

METHODS: Medicare beneficiaries who underwent bariatric surgery from 2013 to 2019 were matched to a control group of patients with obesity with a 1:1 exact matching based on age, sex, body mass index, and propensity score matching on 87 clinical variables. The study outcomes included all-cause mortality, new-onset heart failure (HF), myocardial infarction (MI), and ischemic stroke. An instrumental variable analysis was performed as a sensitivity analysis.

RESULTS: The study cohort included 189,770 patients (94,885 matched patients in each group). By study design, the 2 groups had similar age (mean: 62.33 ± 10.62 years), sex (70% female), and degree of obesity (mean body mass index: 44.7 ± 7.3 kg/m

CONCLUSIONS: Among Medicare beneficiaries with obesity, bariatric surgery is associated with lower risk of mortality, new-onset HF, and MI.
