Introduction: This study investigated the mortality rates during the postoperative early period (one month) in patients who underwent on- or off-pump coronary artery bypass grafting (CABG) and explored the effects of cardiopulmonary bypass (CPB) on early mortality and cerebral accident. Patients and Methods: This study comprises a total of 260 subjects that underwent CABG surgery in our clinic. Patients who underwent CABG were grouped according to two different surgical techniques: the first group (Group 1) consisted of patients who underwent CABG using CPB and cross-clamp (on-pump); the second group (Group 2) consisted of patients who underwent CABG by beating heart (off-pump) technique. Proximal anastomoses were performed using side clamps in all cases. Results: Postoperative follow-up was conducted on patients until Day 30 for mortality. We encountered four dead cases and six cerebrovascular accidents. Conclusion: The rates of cerebral accidents (2.4% vs. 2.1%) and deaths (1.8% vs. 1%) have the same ratios and are not statistically significant in on-pump CABG surgeries compared with off-pump CABG surgeries.
