Atrial fibrillation in patients undergoing coronary artery surgery is associated with adverse outcome.

ABSTRACT:

Background

The aim was to determine the association between atrial fibrillation (AF) and outcome in patients undergoing coronary artery bypass grafting (CABG).

Methods

All patients undergoing CABG between January 2010 and June 2013 were identified in the Swedish Heart Surgery Registry. Outcomes studied were all-cause mortality, cardiovascular mortality, myocardial infarction, congestive heart failure, ischemic stroke, and recurrent AF. Patients with history of AF prior to surgery (preoperative AF) and patients without history of AF but with AF episodes post-surgery (postoperative AF) were compared to patients with no AF using adjusted Cox regression models.

Results

Among 9,107 identified patients, 8.1% (n = 737) had preoperative AF, and 25.1% (n = 2,290) had postopera
