Early Outcomes of Coronary Artery Bypass Grafting in Patients with Recent Non-ST Segment Elevation Myocardial Infarction

Background: Coronary artery disease (CAD) remains a major contributor to global mortality. Non-ST-segment elevation myocardial infarction (NSTEMI) is a high-risk acute coronary syndrome with increasing prevalence.
Aim: This research aimed to evaluate early results ofcoronary artery bypass grafting (CABG) in cases with recent NSTEMI in comparison with those undergoing elective CABG without myocardial infarction.
Patients and methods: This prospective, analytical case-control research involved 80 patients scheduled for isolated CABG at Kasr Al-Ainy Hospitals through the period from September 2024 to February 2025.
Results: Statistically insignificant variances were observed among the 2 groups according to gender, age, operative time, number of grafts, body mass index (BMI), cross-clamp time, Intensive Care Unit (ICU)/hospital stay duration, and postoperative complications such as arrhythmia, bleeding, stroke, or need for reoperation (p > 0.05). No mortality occurred in either group during the 30-day follow-up. Although NSTEMI patients had slightly longer cardiopulmonary bypass times, the differences were not significant.
Conclusion: Early CABG in patients with recent NSTEMI is associated with comparable short-term outcomes to those without prior MI. It can be considered a safe strategy in carefully selected patients.
