Intraoperative hypotension, new onset atrial fibrillation, and adverse outcome after carotid endarterectomy.

Background: Information regarding predisposing factors, frequency, and prognostic implications of new onset atrial fibrillation (NOAF) after carotid endarterectomy (CEA) is scarce. We assessed the frequency, risk factors, and the prognostic impact of NOAF after CEA.

Methods: We assessed every patient undergoing CEA (n = 186) at our academic hospital between 2006 and 2009.
