Early postoperative outcome of coronary artery bypass grafting in patients with previous coronary stenting

Background: Rates of percutaneous coronary intervention 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 postoperative outcomes, and complications of CABG surgery following previous revascularization by percutaneous intervention. Patients and Methods: This prospective study was conducted on One hundred and twenty patients with multi-vessel CAD (coronary artery disease) 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 ejection fraction, respectively. Conclusion: Our study revealed that there was a significant difference in coronary artery pathology, with severe atherosclerosis in group A compared with group B. Total bypass time and cross clamp time increased in group B. Additionally, there was a slight decrease in ejection fraction follow-up in group A after 3 months.
