Introduction: Coronary artery bypass grafting (CABG) is a vital surgical procedure for coronary heart disease, addressing significant morbidity and mortality. Off-pump CABG (OPCAB) offers potential advantages over conventional on-pump CABG by avoiding cardiopulmonary bypass (CPB)-associated complications. This study examines early postoperative outcomes between these two techniques at the Department of Cardiac Surgery, BSMMU, emphasizing the increasing adoption of OPCAB for safer and effective cardiac surgery. Objectives: To compare early postoperative morbidity and mortality between off-pump and on-pump CABG procedures. Methods and Materials: This prospective cohort study included 40 patients undergoing elective CABG at BSMMU from July 2011 to June 2013. Patients were grouped equally into OPCAB and on-pump CABG cohorts. Data on clinical characteristics, complications, and outcomes were collected through preoperative evaluations, postoperative monitoring, and one-month follow-ups. Statistical analysis assessed significant differences in recovery, morbidity, and mortality between the groups. Results: The study compared Off-pump and On-pump CABG groups. Off-pump patients had shorter operative time (174.3±20.9 vs. 235.3±48.4 min) and required less blood during surgery (1.57±0.69 vs. 2.83±1.04 units), both statistically significant (p<0.05). Mechanical ventilation (7.5±2.7 vs. 16.5±15.7 hours), hospital stay (6.3±0.8 vs. 8.7±2.1 days), and ICU blood usage (1.8±0.76 vs. 3.1±1.12 units) were also lower in Off-pump, with significant differences (p<0.05). NYHA improvement and LVEF changes were comparable (p>0.05). Conclusion: Off-pump CABG showed lower morbidity, mortality, and faster recovery compared to On-pump CABG, with similar functional improvements.
