Abstract
Objectives:
Atrial fibrillation after coronary artery bypass grafting is a relatively well known complication that has been observed for a long time. Though the management and drugs in the perioperative period have changed, their impact on the generation of postoperative atrial fibrillation remains unclear. Therefore, we investigated various perioperative management methods and the occurrence of postoperative atrial fibrillation.
Methods
The patients underwent off-pump coronary artery bypass grafting between January 2010 and October 2019. The study was a retrospective observational study, and we investigated the incidence of atrial fibrillation during all 5 postoperative days. Patient factors included age, sex, height, and weight, preoperative factors included oral statin, HbA1c, left ventricular ejection fraction, and left atrial diameter; intraoperative factors included operation time, remifentanil use, beta-blocker use, magnesium-containing infusions use, in-out balance, and number of vascular anastomoses.
Results
Postoperative atrial fibrillation was recognized in 81 out of 276 cases. There were significant differences between the two groups in terms of age, left atrial diameter, and intraoperative remifentanil use. A logistic regression analysis presented the effects of age (OR 1.045, 95% CI 1.015-1.076, P < 0.01), preoperative left atrial diameter (OR 1.072, 95% CI 1.023-1.124, P < 0.01), and intraoperative remifentanil use (OR 0.492, 95% CI 0.284-0.852, P =0.011) on postoperative atrial fibrillation.
Conclusions
Operative time did not affect postoperative atrial fibrillation. Age and left atrial diameter had previously been shown to affect postoperative atrial fibrillation, and our results were similar. This study showed that the use of remifentanil reduced the incidence of postoperative atrial fibrillation. On the other hand, no other factors were found to have an effect.
