[Early and mid-term outcome of off-pump coronary artery bypass grafting in patients with acute myocardial infarction].
Coronary artery bypass grafting (CABG) is one of the options for treating acute myocardial infarction (AMI). However, the mortality of conventional CABG is reported to be high. Therefore, we assessed the outcomes of off-pump coronary artery bypass grafting (OPCAB) in patients with AMI. Between September 2004 and October 2007, 50 patients with AMI, mean age 71.7 years, were operated on. Anterior, inferior and lateral infarctions were observed in 30, 16 and 4 patients, respectively. The time from AMI to operation was <24 hours in 13 patients, <3 days in 5, <7 days in 9, <14 days in 10 and >14 days in 13. Intra-aortic balloon pumping was used in 44% of the patients. Mean number of anastomoses per patient was 4.0. There was no in-hospital mortality. Low output syndrome was observed in 1 patient, and stroke in 2. Ejection fraction of the left ventricle significantly improved after the operation (p<0.01). The graft patency rate was 97.3%. Actuarial survival was 95.9% at 3.5 years. We concluded that OPCAB is a safe and effective procedure with favorable early and midterm survival outcomes in patients with AMI.
