[Relative factors of recent discovered atrial fibrillation following isolated coronary artery bypass grafting].
OBJECTIVE
To identify the relative factors of recent discovered atrial fibrillation (AF) following isolated coronary artery bypass grafting (CABG).


METHODS
Classified the 649 cases undergoing isolated CABG from January 2005 to December 2006 to two groups according to whether AF appeared after operation. Collected the peri-operative data and operative strategy, then analyzed with single-factor analysis and Logistic regression.


RESULTS
The incidence of AF was 8.0% (52 cases), and 84.6% (44 cases) recovered sinus-rhythm leaving hospital. Age, standard European system for cardiac operative risk evaluation (EuroSCORE), ratio of high-operative-risk, left atrium diameter and ratio of left coronary artery dominance were higher in AF group than in non-AF group. Age, eject fraction, left atrium diameter, operative risk evaluation, left coronary artery dominance and anastomosis on right coronary artery were the relative factors of recent discovered AF following isolated CABG. But off-pump operation, prescription of adrenergic beta-antagonists pre-operatively and degree of coronary artery stenosis had no influence to AF.


CONCLUSIONS
AF following CABG is a result of common influence by many factors. EuroSCORE might forecast partially the incidence of AF following CABG. Improve the myocardial protection and reduce the surgical damage during operative progress maybe the mostly approach to decrease the incidence of AF following CABG.
