Recently, we have demonstrated1 that the occurrence of AF is not confined to the postoperative period and that 6 months after surgery, AF is still present in 39% of the patients who develop postoperative supraventricular arrhythmias.It has been reported that ischemic injury of the atrium promotes AF, although the underlying mechanism remains unclear. In the September 26, 2000, issue of Circulation , Ascione and co-workers2 reported that the incidence of AF after coronary revascularization was significantly decreased, from 45% in patients operated on under cardiopulmonary bypass (CPB) to only 11% …
