Frequency and risk factors of atrial fibrillation after acute abdominal surgery: A prospective cohort study
Authors' conclusion
In conclusion, this prospective study of POAF in patients undergoing acute abdominal surgery showed that one in 20 patients developed clinically recognized in-hospital POAF. Multiple risk factors of POAF were identified. POAF was associated with severe complications up to 30 days after surgery.
