This study will include the subjects who enrolled in pCAD-POAF trial (NCT05009914) to observe clinical outcomes 3 years after surgery. The primary outcome is the AF burden during 3-day continuous ECG monitoring among 2 groups in pCAD-POAF trial 3 years after surgery. The secondary outcomes are：1. Freedom of AF without the use of antiarrhymic medications or interventions ; 2. The occurence of MACCE (including all-cause mortality, stroke, myocardial infarction, systemic arterial embolism, revascularization, and rehospitalization for heart failure); 3. AF incidence in 3 years and recorded by continuous ECG monitoring; 4. Post-operative antiarrhythmic interventions and occurrence of arrhythmias other than AF; 5. The mean, maximum, and minimum heart rate recorded by Holter monitoring, as well as heart rate variability (HRV); 6. Quality of life assessment, such as EQ-5D-5L and AFEQT.
