Background/Objectives. We aimed to investigate the incidence and clinical outcome of coronary artery bypass grafting (CABG) performed in contemporary patients with ST-elevation myocardial infarction (STEMI) within 30 days after presentation.Methods. All 1071 patients enrolled in the Thrombus Aspiration during Percutaneous coronary intervention in Acute myocardial infarction Study (TAPAS) were included in this analysis. CABG was indicated for both ischaemic and anatomical reasons according to the current treatment guidelines for STEMI. For all surgical as well as non-surgical patients, clinical outcome was assessed at both 30 days and one year. Results. CABG was performed within 30 days of presentation in 59/1071 (5.5%) patients, in 13 (22%) within 24 hours, in eight (14%) between one and three days, and in 38 (64%) between four and 30 days. Compared with non-surgical patients, surgical patients required more initial intra-aortic balloon pump support (33 vs. 5%, p<0.001) and more often had multi-vessel disease (p<0.001). Overall, rethoracotomy was performed in 9/59 (15%) patients. In patients operated within three days, the rethoracotomy rate was markedly higher than after three days (33 vs. 5%, p=0.004). Cardiac mortality at 30 days and one year was 1.7% in the surgical group and 3.2 and 5.3%, respectively, in the non-surgical group. Conclusion. STEMI patients treated with CABG within three days after presentation are at increased risk of rethoracotomy. However, despite this higher incidence of surgical complications and multiple high-risk features at presentation, surgical management during the acute and subacute phase is associated with excellent 30-day and one-year survival.
