Postoperative Atrial Fibrillation Following Off-pump Coronary Artery Bypass Grafting / 日本心臓血管外科学会雑誌

ABSTRACT

It has been demonstrated that atrial fibrillation (AF) frequently occurs after coronary artery bypass grafting (CABG) and may cause cerebral infarction. The purpose of this research is to clarify the risk factors of AF in patients who underwent off-pump CABG (OPCABG). In this study, 142 patients (111 men and 31 women) were enrolled with an average age of 67 years old (range, 33-83). According to multivariate analysis, age and the preoperative peak early (E)/late (A) diastolic velocities ratio (E/A) were the independent predictors of postoperative AF. Patients who suffered from postoperative AF required a significantly longer hospital stay.
