[Emergency myocardial revascularization in non-ST-segment elevation acute coronary syndrome (literature review)]

Present-day guidelines on treatment of non-ST-segment elevation acute coronary syndrome do not determine the place of emergency coronary artery bypass grafting in this condition, however underlining that in high-risk patients, revascularization should be performed within the first 24 hours. Analysing the evidence-based data of using emergency coronary artery bypass grafting demonstrated that performing intra-aortic balloon counterpulsation prior to operation in high-risk patients with non-ST segment elevation acute coronary syndrome improved clinical outcomes. It was shown that CABG on the beating heart in patients with acute coronary syndrome improved outcomes of surgical revascularization and may be a method of choice in such patients, provided complete revascularization is achieved. We also analysed studies comparing the results of coronary artery bypass grafting and percutaneous interventions, demonstrating that CABG at the expense of a persistent effect improved the long-term prognosis and reduced the risk of repeat revascularizations in future.
