Abstract
BACKGROUND
Superior clinical outcomes after hospitalization for cardiovascular-related disease such as acute heart failure have been linked with prior history of bariatric surgery, but similar analyses in acute myocardial infarction (MI) are currently limited.
OBJECTIVE
This work examines clinical outcomes and resource utilization in patients with acute MI hospitalizations with a prior history of bariatric surgery.
SETTING
Academic university-affiliated hospital in the United States.
METHODS
All adult patients with hospitalizations with a primary diagnosis of acute MI were queried using the 2016-2020 Nationwide Readmissions Database. The study population was comprised of patients with an International Classification of Diseases, Tenth Revision (ICD-10) diagnosis code for obesity (body mass index ≥35 kg/m2) as well as those with a prior history of bariatric surgery regardless of their body mass index status. Comparison was made between those with a prior history of bariatric surgery and those without. Univariate analysis and multivariate regression models were used to examine the association between bariatric surgery and outcomes of interest, which included in-hospital mortality, medical complications, and resource utilization.
RESULTS
Of an estimated 2,736,606 hospitalizations for acute MI, 296,902 patients (10.8%) had a diagnosis of obesity and/or a prior history of bariatric surgery. The bariatric cohort was more frequently female and had a lower prevalence of congestive heart failure, chronic lung disease, diabetes, and electrolyte derangements than the nonbariatric cohort. After risk adjustment, prior history of bariatric surgery was associated with significantly lower odds of in-hospital mortality, cardiogenic shock, and acute kidney injury. Additionally, prior history of bariatric surgery was linked to a decreased duration of hospital stay and lower hospitalization costs as well as lower odds of nonhome discharge.
CONCLUSION
Among acute MI patients with obesity, prior history of bariatric surgery was associated with decreased odds of in-hospital mortality, improved clinical outcomes, and lower resource utilization. Expansion of bariatric surgery programs may provide improved access to a medical intervention that is intertwined with cardiovascular health.
