Background: Metabolic bariatric surgery (MBS) not only leads to a durable weight loss but also lowers mortality, and reduces cardiovascular risks.
Objectives: The current study aims to investigate the association of bariatric metabolic surgery (BMS) with admissions for acute myocardial infarction (AMI), including ST-elevation myocardial infarction (STEMI) and non-ST-elevation myocardial infarction (NSTEMI), as well as, coronary revascularization procedures, including percutaneous coronary intervention (PCI), coronary artery bypass graft (CABG), and thrombolysis.
Setting: The National Inpatient Sample (NIS) database.
Methods: The NIS data from 2016 to 2020 were analyzed. A propensity score matching in a 1:1 ratio was performed to match patients with history of MBS with non-MBS group.
Results: Two hundred thirty-three thousand seven hundred twenty-nine patients from the non-MBS group were matched with 233,729 patients with history of MBS. The MBS group had about 52% reduced odds of admission for AMI compared to the non-MBS group (adjusted odd ratio: .477, 95% confidence interval: .454-.502, P value <.001). In addition, the odds of STEMI and NSEMI were significantly lower in the MBS group in comparison to the non-MBS group. Also, the MBS group had significantly lower odds of CABG, PCI, and thrombolysis compared to the non-MBS group. In addition, in patients with AMI, MBS was associated with lower in-hospital mortality (adjusted odd ratio: .627, 95% confidence interval: .469-.839, P value = .004), length of hospital stays, and total charges.
Conclusions: History of MBS is significantly associated with reduced risk of admission for AMI including STEMI and NSTEMI, as well as the, need for coronary revascularization such as PCI and CABG.
