Purpose: We evaluated a treatment strategy for acute myocardial infarction (AMI) that percutaneous coronary intervention (PCI) is performed on a culprit lesion unless the culprit is an unprotected left main trunk. Emergent coronary artery bypass grafting (CABG) is done when the culprit is a left main trunk and a mechanical complication exists.Methods: From 1997 to 2008, 22 and 232 patients underwent CABG for AMI and non-AMI, respectively. Of the 22 patients of AMI, PCI was performed in 12 patients and not performed in 10 patients before surgery. We investigated complication, intubation period, in-hospital mortality and hospitalization period. Results: No in-hospital mortality was observed in all 22 AMI patients. There was no difference in in-hospital mortality and complication between the AMI and the non-AMI patients. No significant difference was found in hospital stay, complication, intubation period, in-hospital mortality and hospitalization period between patients who received preceding PCI and not. Conclusions: These results suggest that our treatment strategy is reasonable. Further studies will be warranted to clarify the role of preceding PCI.
