Abstrakt:	Background: This study aimed to investigate the intraoperative and early postoperative effects of modified del Nido cardioplegia (DNC) compared to classic blood cardioplegia (BC) in patients with impaired left ventricular ejection fraction (EF) who underwent isolated coronary artery bypass grafting (CABG). Methods: A total of 123 patients (108 males, 15 females; mean age: 62.2±8.5 years; range, 42 to 78 years) with an EF of 35% or lower who underwent on-pump CABG were included in the retrospective study between December 2022 and December 2023. The patients were divided into two groups according to the type of cardioplegia used: Group 1 (n=74) was designated as the BC group, and Group 2 (n=49) was designated as the DNC group. The groups were compared in terms of aortic cross-clamp duration, cardiopulmonary bypass (CPB) duration, need for defibrillation during weaning from CPB, positive inotrope requirement, intra-aortic balloon pump requirement, postoperative troponin-I levels, postoperative atrial fibrillation occurence, postoperative prolonged ventilation, development of postoperative neurologic complications, need for reintervention due to postoperative bleeding, postoperative transfusion requirement, and EF values at one month after the operation. Results: There was no significant difference between the two groups in the terms of aortic cross-clamp and CPB duration (p=0.955 vs. p=0.816). Additionally, there was no significant difference in the need for intra-aortic balloon pump usage between the two groups (p=0.105). Dopamine and dobutamine usage were significantly lower in Group 2 (p=0.04 and p=0.05, respectively). The intraoperative requirement for defibrillation was significantly lower in Group 2 (p=0.01). In addition, troponin levels at 12 h postoperatively were significantly lower in Group 2 (p=0.03). The incidence of postoperative atrial fibrillation was significantly lower in Group 2 (p=0.02). Moreover, there was no significant difference in EF values at one month after the operation (p=0.08). Conclusion: In patients who underwent CABG with reduced EF, modified DNC provided myocardial protection comparable to classic BC. Additionally, the need for intraoperative defibrillation and postoperative inotropic agents, as well as the incidence of postoperative atrial fibrillation, were lower in patients operated with DNC.
