Abstract

New-onset atrial fibrillation (AF) is common form of rhythm disturbance following coronary artery bypass grafting (CABG) surgery. It is still unclear which factors have a significant impact on its occurrence after this procedure. The relationship between preoperative low heart rate variability (HRV) and AF after CABG surgery has been investigated with divergent results. Objective: To evaluate clinical predictors of postoperative atrial fibrillation (POAF) after myocardial revascularization. Subjet and method: The study involved 119 consecutive patients who underwent the first CABG operation without baseline AF. All subjects underwent assessed with 24-hour Holter recordings 2 days preoperative and 7 days, 3 months, 6 months postoperative at Hanoi Heart Hospital from 6/2016 to 8/2018. Result: The incidence of POAF varies from 13.7% (7 days), to 13.8% (3 months) and to 17.2% (6 months). The incidence of pre and postoperative low HRV varies from 28.6% (preop) to 51.8% (postop 7 days), 19.6% (postop 3 months) and 12.7% (postop 6 months). In which, reduced HRV preoperative had the risk of developing POAF 3.04 - 4.3 times (p<0.05). Multivariate logistic regression analysis was used to identify the following independent clinical predictors of POAF: Diabetes mellitus (RR = 0.16, 95%CI: 0.03 - 0.76; p<0.05), preoperative with low HRV (RR = 3.02, 95%CI: 1.01 - 8.96, p<0.05). Conclusion: Preoperative with low HRV was pedict a risk factor for POAF following coronary artery bypass grafting.
