A time-related parametric risk factor analysis for postoperative atrial fibrillation after heart surgery

Abstract

Phase I and phase II periods are associated with distinct risk factors; therefore, it is likely that the mechanisms of postoperative atrial fibrillation change over time.

Preoperative Tissue Doppler Imaging-Derived Atrial Conduction Time Predicts Postoperative Atrial Fibrillation in Patients Undergoing Mitral Valve Surgery for Mitral Valve Regurgitation

“…3 Melby et al reported that patients receiving MVS had a higher risk of POAF compared with patients receiving CABG. 12 The present study showed that the incidence of postoperative heart failure tended to be higher in patients with POAF, and 2 patients had cerebral infarction during POAF. Furthermore, in patients with degenerative disease, the presence of POAF significantly prolonged hospital stay by more than 27 days.…”

Postoperative atrial fibrillation in non‐cardiac and cardiac surgery: an overview

“…POAF typically occurs on postoperative day 2, with 70% of cases occurring within the first four postoperative days [32]. Melby et al [33] conducted a time series analysis on patients after bypass and valvular surgeries and documented two postoperative periods where patients are at highest risk of POAF. They proposed a trajectory whereby the highest risk occurs immediately after surgery with a second increase in risk occurring 48 h postoperatively.…”

New-onset postoperative atrial fibrillation after aortic valve replacement: Effect on long-term survival

“…Recently, incidence rates of new-onset POAF after isolated aortic valve replacement (AVR) or CABG with concomitant AVR were 28% and 39%, respectively. 4 New-onset POAF appeared to affect both mental and physical health months after CABG. 5 In some studies, new-onset POAF was associated with decreased 30-day survival after cardiac surgery.…”
