Eighty six (43 in each on-pump and off-pump) patients admitted for elective coronary artery bypass grafting, aged 30-80 years were included in the study. Baseline data and cardiac troponin-I levels preoperatively as well as at 6, 12, 18 and 24 hours after the surgery in both groups were recorded and analyzed.</p> <p><strong>Results:</strong> Out of 100 patients, mean age of the patients was 57.59 ± 10.24 years and 85% were males. All the base line characteristics, comorbid conditions and intra-operative findings were identical in both groups. There was marked rise in CK-MB levels postoperatively in overall participants. There was significant rise in Troponin I levels postoperatively in overall participants. Compared to OPCAB, postoperative Troponin I at 6hours and 12-hours was significantly higher in ONCAB.</p> <p><strong>Conclusion:</strong> Compared to OPCAB, postoperative Troponin I at 6 hours and 12-hours was significantly high in ONCAB. However, there was no gross discrepancy in postoperative Troponin I levels between OPCAB and ONCAB at 18- & 24-hours after surgery.</p>}, number={Suppl-4}, journal={Pakistan Armed Forces Medical Journal}, author={Ullah, Kifayat and Waseem, Muhammad and Janjua, Asif Mahmood and Khadim, Shakila and Amin, Mashood Shahid and Ashfaq, Muhammad and Mustafa, Anum}, year={2021}, month={Jan.}, pages={S849–54} }
