摘要
Objective： To investigate the incidence and relative risk factors of post coronary artery bypass grafting（post-CABG） atrial fibrillation （AF）. Methods： 312 patients with CABG were reviewed and divided into an AF group and a non-AF group. Statistical analysis was used to compare the data between the two groups and screen for risk factors of post-CABG AF. Results： 103/312 （33.01%） patients developed post-CABG AF. Univariate analysis showed that patients in AF group compared with those in non-AF group were more likely to have advanced age （≥ 70 years）, early postoperative withdrawal of β-blockers, hypertension, left atrial enlargement （≥40 mm）, a history of AF, prolonged p-wave duration （≥ 120 ms） and increased number of grafts （≥13）. Multivariate logistic regression analysis showed that advanced age （≥70 years）, early postoperative withdrawal of β-blockers, hypertension, left atrial enlargement （≥40 mm） and a history of AF were highly related to post-CABG AF. Conclusion： The incidence of AF in patients following CABG was 33.01% in this study. Advanced age, early postoperative withdrawal of 13-blockers, hypertension, left atrial enlargement and a history of AF were independent risk factors of post-CABG AF.
