Incidence and Clinical Implications of Postoperative Atrial Fibrillation in patients Undergoing On-Pump and Off-Pump Coronary Artery Bypass Grafting

Abstract

Aim: Post-operative incidence and clinical implications of atrial fibrillation in patients having on-pump and off-pump CABG. Place of Study: Department of Cardiovascular & Thoracic Surgery, Shaikh Zayed Hospital, Lahore. Study Duration: 1 year Design of Study: Quasi-experimental study Methodology: 140 cases were selected. Non-probability purposive sampling technique was used. Grouping: Group A (Off-pump) and Group B (On-pump). Results: In group A, cases showed atrial fibrillation and in group B 23(32.9%) cases were noted. The incidence of postoperative atrial fibrillation was low in off-pump CABG as compare to on pump CABG.Clinical implications of postoperative AF such as, length of ICU & hospital stay, cerebrovascular events, wound infections and mortality of the cases are significantly reduced by using off-pump CABG. Conclusion: Incidence of P/O atrial fibrillation is low in off-pump CABG as compare to on pump CABG Keywords: Coronary Artery Bypass Graft (CABG), Atrial Fibrillation, on pump CABG.
