Postoperative Atrial Fibrillation Is Associated With Late Mortality After Coronary Surgery, but Not After Valvular Surgery

Atrial fibrillation following off-pump versus on-pump coronary artery bypass grafting: Incidence and risk factors

“…Although in some studies it has been considered a benign and self-limiting complication, some data suggest serious morbidity and an increase in outcomes in patients who developed AF postoperatively [7,8]. In a large study, Mariscalco et al [9] found that long-term mortality rates were significantly higher in patients with postoperative AF.…”

Validation of SYNTAX and clinical SYNTAX scores in predicting atrial fibrillation following on-pump coronary artery bypass grafting

“…[10] It typically occurs within the first four postoperative days. [11] Although numerous risk factors predisposing to PoAF development have been identified such as advanced age, anemia, hypoxia, left atrial dilatation, left ventricular dysfunction, severe CAD, hypertension, type of cardiac surgery, increased sympathetic activation, oxidative stress and inflammation, the main pathophysiology of PoAF has not been well-understood completely and it is likely multi-factorial in cause.…”

Left-ventricular electromechanical delay is prolonged in patients with postoperative atrial fibrillation

“…Such patients were included for several reasons. First, despite the evidence of the larger incidence of AF in mitral valve surgery than in coronary artery bypass grafting (CABG) [18], the incidence of postoperative AF was not different between mitral valve and ischemic heart disease during the study period in our institution (unpublished data in 2009), and we intended to find a general parameter for AF. Second, we also included off-pump CABG patients.…”
