    A retrospective cohort study analyzed hospitalization outcomes for atrial fibrillation or flutter in patients with and without prior thoracic radiation therapy.

  • 2

    Among 3,198,304 weighted admissions, 8,570 had prior thoracic radiation therapy, linked to higher in-hospital mortality and longer length of stay.

    Patients with prior thoracic radiation therapy had higher odds of palliative consultation and do-not-resuscitate status, but lower odds of acute kidney injury.

  • 4

    The study utilized propensity score matching and multivariable regression to evaluate outcomes, addressing confounding factors in the analysis.

  • 5

    Findings highlight the clinical complexity of atrial arrhythmia hospitalizations in patients with a history of thoracic irradiation.
