Early post operative outcome of CABG In patients with previous coronary stenting

Background: Rates of percutaneous coronary intervention (PCI) have increased dramatically in recent years, whereas rates of coronary artery bypass grafting (CABG) have remained remarkably stable.Aim: To evaluate the impact of coronary stenting on coronary artery pathology and the way of grafting, the early post- operative outcomes and complications of coronary artery bypass grafting surgery following previous revascularization by percutaneous intervention (PCI).Patients and methods: This prospective study was conducted on One hundred and twenty patients with multi-vessel CAD and indicated for CABG in ASU hospital and Sheikh Zayed specialized hospital between February 2019 and March 2024.Results: There was no significant difference in the incidence of myocardial infarction and cerebrovascular stroke between group A and group B, no significant difference in postoperative cardiac enzymes, ECG, or echocardiography after 3 months of EF, respectively.Conclusion: Our study revealed that there was a significant difference in coronary artery pathology, with severe atherosclerosis in group A compared to group B. Total bypass time and cross clamp time increased in group B. Additionally, there was a slight decrease in EF follow-up in group A after 3 months.
