Preoperative atrial fibrillation tied to adverse outcomes after noncardiac surgery: JACC
USA: A recent study in the Journal of the American College of Cardiology (JACC) found pre-existing atrial fibrillation to be independently associated with postoperative unfavorable outcomes following noncardiac surgery (NCS).
Atrial fibrillation whether perioperative, pre-existing, or postoperative poses a unique challenge, and is shown to be associated with worse outcomes in the surgical settings. The data is scant regarding outcomes associated with pre-existing AF in the setting of noncardiac surgery despite robust retrospective analyses of perioperative.
Considering the above, Sameer Prasada, Heart, Thoracic and Vascular Institute, Cleveland Clinic, Cleveland, Ohio, USA, and colleagues aimed to study the impact of AF on the risk of adverse outcomes after noncardiac surgery in a nationwide cohort.
For this purpose, the researchers identified Medicare beneficiaries admitted for noncardiac surgery from 2015 to 2019. The study cohort was divided into 2 groups: with and without AF. Noncardiac surgery was classified into thoracic, vascular, general, gynecological, genitourinary, neurosurgery and orthopedics, breast, head and neck, and transplant.
