[Emergency coronary artery bypass grafting for acute coronary syndrome].
Emergency CABG for acute coronary syndrome (ACS) was studied. Sixty patients had CABG for medically refractory UAP, 78 patients for AMI and 8 patients for post-infarction angina (PIA). In UAP group 7 patients (12%) died postoperatively, mainly due to perioperative myocardial infarction (PMI) and operative complications. In AMI group, 26 patients (33%) died, 14 of them due to myocardial failure. The operative mortality was extremely high in shock-state patients group (48%) and cardiac pulmonary arrest state patients group (85%). Operative result was poor in those patients whose infarct-related artery was not recanalized preoperatively. Operative mortality was 13% in PIA group. It was concluded that the reduction of mortality of those patients required much refined myocardial preservation technique and powerful mechanical assist system to support the postoperative myocardial failure.
