Atrial Fibrillation after Off-pump Coronary Artery Surgery: A Prospective, Matched Study

The effect of cardiopulmonary bypass and myocardial ischaemia on the occurrence of atrial fibrillation (AF) after coronary artery bypass graft (CABG) was studied in 136 patients undergoing off-pump CABG who were matched for age and number of distal anastomoses with 136 patients undergoing on-pump CA...

Description
Summary:The effect of cardiopulmonary bypass and myocardial ischaemia on the occurrence of atrial fibrillation (AF) after coronary artery bypass graft (CABG) was studied in 136 patients undergoing off-pump CABG who were matched for age and number of distal anastomoses with 136 patients undergoing on-pump CABG. Possible risk factors for postoperative new-onset AF were recorded. AF occurred in 64 (24%) of the 267 patients for whom data could be analysed. AF occurred in 29 patients (22%) in the off-pump group versus 35 (26%) in the on-pump group, but this difference was not statistically significant. On univariate analysis, age and length of hospital stay were significant risk factors for the occurrence of AF. In a multivariate analysis that included operative technique, age was found to be the only significant risk factor. In conclusion, the occurrence of AF after CABG does not depend on the type of operation.
