OBJECTIVE: To evaluate safety of coronary artery bypass surgery using bilateral internal mammary artery and effectiveness of this procedure in long-term postoperative period.
MATERIAL AND METHODS: The study involved 129 patients who underwent CABG for the period 2006-2007. There were 2 groups of patients depending on surgical strategy: group 1 (n=61) - double IMA harvesting, group 2 (n=68) - CABG using single IMA. Short-term results were compared using standard statistical methods. Long-term survival was compared using Kaplan-Meyer method.
RESULTS: Revascularization index was 3.014±0.76 in the 1st group and 3.1±0.73 in the 2nd group (p>0.05). In-hospital mortality was 0% and 1.47%, respectively (p> 0.05). A 10-year survival was 95.1% and 91.2%, respectively (p>0.05). Freedom from cardiac events (mortality, myocardial infarction, recurrent angina pectoris) was significantly different (95% vs. 81%, p<0.05).
CONCLUSION: Significantly lower rate of adverse cardiac events in long-term postoperative period in comparison with conventional CABG clearly demonstrates high quality of life after coronary artery bypass surgery using bilateral internal mammary artery for a long time. Therefore, this procedure is preferred in patients with coronary artery disease.
