This valuable experience led us to develop a stroke-free management strategy for patients undergoing CABG.In the recent years, POAF has been reported as a complication in 30% of CABG, 50% of valvular surgery, 30% of pneumonectomy, and 20% of esophagectomy cases in general surgery30). More-over, the 2020 European Cardiology Guidelines states that POAF is 4-5 times more likely to recur than normal sinus rhythm after a 5-year follow- Age>75 (years) (yes=1)Sex (Male=1)Body mass index >30 (yes=1)Hypertension (yes=1)Lipid disorder (yes=1)Diabetes Mellitus (yes=1)Peripheral arterial disease (yes=1)Previous stroke (yes=1)Chronic kidney diseaseeGFR<60 (ml/min/1.73m2) (yes=1)Hemodialysis (yes=1)LVEF<40% (yes=1)LVEF: Left ventricular ejection fraction.Age>75 (years) (yes=1)Sex (Male=1)Body mass index >30 (yes=1)Hypertension (yes=1)Lipid disorder (yes=1)Diabetes Mellitus (yes=1)Peripheral arterial disease (yes=1)Previous stroke (yes=1)Chronic kidney diseaseeGFR<60 (ml/min/1.73m2) (yes=1)Hemodialysis (yes=1)LVEF<40% (yes=1)LVEF: Left ventricular ejection fraction.Table 4　Multivariate predictors for MACE; Major Adverse Cardiovascular EventsTable 3　Multivariate predictors for hospital mortalityUnivariateP value<0.0010.090.480.02<0.0001<0.001<0.001<0.001<0.001<0.001<0.001UnivariateP value0.240.490.0010.040.500.26<0.00010.003<0.001<0.001<0.001up31). These findings have even led to the opinion that pulmonary vein isolation and surgical inter-vention of the LAA may be desirable in the pres-ence of any risk factor for AF30). Although there is no evidence that POAF tends to convert to distant AF after surgery since the valuable publication in 201432), Endo and his colleagues found that the recurrence rate of POAF was high and 20% of patients converted to chronic AF at least ten years after surgery (Figure 7)33). Furthermore, the same analysis showed that 8% of all cases older than 70 years had converted to chronic AF.MultivariateOR (95%CI)2.03(1.94-2.72)1.10(0.91-1.33)0.67(0.57-0.79)1.30(1.11-1.53)1.69(1.39-2.06)1.43(1.18-1.73)3.16(2.50-3.99)1.69(1.43-2.00)MultivariateOR (95%CI)2.03(1.36-3.02)1.13(0.90-1.42)1.55(1.21-1.99)1.31(1.02-168)2.24(1.63-3.07)1.38(1.11-1.70)P value<0.0010.30<0.0010.001<0.001<0.001<0.0010.003P value<0.00010.30 <0.00010.03<0.0010.003107
