Objective: Studies that have specifically compared arrest and beating methods in on-pump CABG are limited.

Methods and Material: In this retrospective cohort study that was conducted in Ghaem Hospital of Mashhad between November 2020 and 2022, data were extracted from all patients' records that underwent on-pump beating CABG or on-pump arrest CABG. According to the method of operation, other variables including post operation bleeding , atrial and ventricular arrhythmia, returning the patient to the operating room for bleeding, need for inotrope, need for a balloon pump, hospital mortality, superficial and deep sternal infection and dehiscence, kidney injury, delayed extubation, length of hospital and ICU stay and neurological complications were compared in the two groups.

Results: A total of 105 patients with an average age of 61.07 ± 10.55 years were included in the study. Of these, 65 cases (61.9%) were male and the rest were female. Of the total patients included in the study, 60 were in the beating group and 45 were in the arrest group. The postoperative outcomes were compared and there was no significant difference between the two groups in terms of patients' outcomes (p>0.05). Also, the comparison of in-hospital and one-month mortality of patients in two groups showed that there was no significant difference between the two groups (p>0.05).

Conclusion: Our study showed that postoperative complications, in-hospital and one-month mortality are not significantly different between on pump arrest CABG and on pump beating CABG.
