Inclusion Criteria:
* more than 18 years old
* undergoing CABG
* Provide informed consent
Exclusion Criteria:
* History of prior cardiac surgery or atrial fibrillation ablation;
* Emergency coronary artery bypass grafting (CABG);
* Concomitant cardiac procedures (e.g., congenital heart disease repair, left ventricular reconstruction, valve surgery, or aortic surgery);
* Critical preoperative status requiring mechanical or pharmacological support before CABG;
* Left ventricular ejection fraction (LVEF) \<35%;
* History of atrial fibrillation (defined as a supraventricular tachyarrhythmia characterized by rapid and irregular atrial electrical activity);
* Significant mitral valve disease (mitral valve area \<1.5 cm² or regurgitant jet area \<4 cm²), significant aortic valve disease (valve area \<1.5 cm² or regurgitant jet-to-left ventricular outflow tract ratio \>25%);
* Severe left atrial enlargement (left atrial anteroposterior diameter \>55 mm);
* Poorly controlled hyperthyroidism;
* Conditions requiring radiotherapy, chemotherapy, or long-term hormonal therapy;
* Patients with known clinical contraindications to stellate ganglion block (SGB).
