The evidence on risk factors and complications associated with perioperative AF after noncardiothoracic surgery is limited.<h4>Methods</h4>The primary objective was to determine demographic and clinical risk factors for new-onset atrial fibrillation associated with noncardiothoracic surgery. A secondary aim was to identify the incidence and odds of perioperative complications associated with the new-onset atrial fibrillation. A systematic search within multiple databases was conducted for studies that explicitly reported on new-onset atrial fibrillation after noncardiAnesthesiology research and practice5527199https://www.ebi.ac.uk/biostudies/studies/S-EPMC8099514biostudies-literatureIncidence, Risk Factors, and Outcomes of Perioperative Atrial Fibrillation following Noncardiothoracic Surgery: A Systematic Review and Meta-Regression Analysis of Observational Studies.PMC8099514Yang HSubramani YFayad ANagappa MJalali DEl Tohamy OfalseIncidence, Risk Factors, and Outcomes of Perioperative Atrial Fibrillation following Noncardiothoracic Surgery: A Systematic Review and Meta-Regression Analysis of Observational Studies.<h4>Background</h4>Atrial fibrillation (AF) occurs in 16-30% of patients after cardiac and thoracic surgery and can lead to serious complications like hypoperfusion of vital organs, pulmonary edema, and myocardial infarction.
