Implications of new-onset atrial fibrillation after cardiac surgery on long-term prognosis: A community-based study

Postoperative atrial fibrillation (POAF) is a common complication after cardiac surgery. Data are lacking on the long-term prognostic implications of POAF. We hypothesized that POAF, which reflects underlying cardiovascular pathophysiologic substrate, is a predictive marker of late AF and long-term mortality.We identified 603 Olmsted County, Minnesota, residents without prior documented history of AF who underwent coronary artery bypass graft...
