Frequency of Postoperative Atrial Fibrillation (POAF) in Diabetic Patients Underwent Elective Coronary Artery Bypass Grafting Surgery (CABG).

Abstract

Introduction: Postoperative atrial fibrillation (AF) is a common problem after cardiac surgery with cardiopulmonary bypass (CPB). It can cause increased morbidity including stroke and need prolonged hospital stay and cost^1,2.

The present study was undertaken in our local population to document the frequency of Postoperative atrial fibrillation (POAF) in diabetic patients who preoperatively had normal ejection fraction underwent elective coronary artery bypass surgery (CABG).

Objective: To document the frequency of Postoperative atrial fibrillation (POAF) in diabetic patients underwent elective coronary artery bypass grafting surgery (CABG).

Material and Method: This Descriptive case series was conducted at the department of Cardiac Surgery, Civil Hospital, Karachi from January 2019 to June 2019.

Total one hundred and four patients undergone elective, isolated, coronary artery bypass grafting surgery who have preoperative normal ejection fraction and normal serum potassium levels (4.5 – 5.5mEq/L). Patients were monitored postoperatively for four days from the day of surgery. Twelve lead ECG was done daily of all patients.

Results: Total one hundred and four patients included in the study with average age of 54.8±7.076 years. Eighty (76.92%) were male and 24 (23.08%) were female. Out of 52 diabetic patients, 14(26.9%) postoperatively developed AF.

Conclusion: In our study the frequency of Postoperative atrial fibrillation (POAF) in diabetic patients underwent elective coronary artery bypass surgery (CABG) was found to be 26.9% (14 patients).
