[Research progress of postoperative atrial fibrillation].

Postoperative atrial fibrillation (POAF) is the most common complication after cardiac surgery, which leads to hemodynamics disorder, prolongs hospitalization and increases mortality. The underlying mechanisms behind POAF are associated with cardiomyocyte injury, sympathetic activation and inflammation. The prediction of POAF is based on correlated index from pre-, intra- and post-surgery. POAF can be treated by rhythm and heart rate control as well as and antithrombotic therapy.
