Acute care outcomes in patients admitted for atrial fibrillation who had prior metabolic surgery: A propensity score matched analysis.

BACKGROUND

Severe obesity increases atrial fibrillation (AF) burden; whether prior metabolic surgery (MS) improves outcomes during AF hospitalization is uncertain.

METHODS

Using a nationally representative database, we queried all primary admissions for AF and severe obesity. Patients were propensity score matched and analyzed with survey-weighted regression analysis.

RESULTS

Among 785,829 hospitalizations, 31,328 (4.0%) had prior MS. MS was associated with lower odds of mortality (AOR 0.60, 95% CI 0.48 - 0.76), acute kidney injury (AOR 0.72, 0.68 - 0.77), acute heart failure (AOR 0.76, 0.71 - 0.80), cardiogenic shock (AOR 0.50, 0.35 - 0.72), and non-home discharge (AOR 0.72, 0.67 - 0.77), with shorter LOS by 0.56 days and lower hospitalization costs by $885.

CONCLUSIONS

Prior MS is associated with improved clinical outcomes and resource use during AF hospitalization.
