| Summary: | Objective To evaluate the clinical efficacy of off-pump coronary artery bypass grafting in the treatment for acute myocardial infarction. Methods A total of 43 patients with acute myocardial infarction who were given off-pump coronary artery bypass grafting (OPCAB) surgery by the same medical team in Department of Cardiovascular Surgery of our hospital from February 2014 to January 2020 were enrolled as the treatment group, and their clinical data were collected and retrospectively analyzed. Among them, there were 5 females and 38 males, at a mean age of 62.40±9.14 years, 20 cases (46.5%) of left main coronary artery disease and 23 cases (53.5%) of multi-vessel disease, and 8 cases (18.6%) of ST-segment elevation myocardial infarction (STEMI), and 35 cases (81.4%) of non-ST-segment elevation myocardial infarction (NSTEMI). Another 46 patients of non-acute myocardial infarction who also underwent OPCAB during the same period were randomly selected and assigned into the control group, including 8 females and 38 males (62.40±9.14 years old), and 25 cases (54.3%) of left main disease and 21 cases (45.7%) of multi-vessel disease. The clinical indicators during the operation, at the first day following operation, and during the hospitalization period were collected and compared between the 2 groups. Results In the treatment group, 2 patients were converted to operation under cardiopulmonary bypass because of intraoperative ventricular fibrillation, 1 patient died of arrhythmia, and 1 experienced postoperative cerebral infarction. In the control group, there was no death and 1 case developed cerebral infarction. However, as for the clinical indicators during the operation, at the first day following operation, and during hospitalization, there were no significant differences between the 2 groups. Conclusion Off-pump coronary artery bypass grafting is safe and effective for patients with acute myocardial infarction.
