Justification. To this day, the problem of choosing the method of complete revascularization in the category of patients with acute coronary syndrome without the ST segment elevation and multi-vascular lesions of the coronary bed does not lose its relevance. The goal of this study was to compare the results of surgical manipulations in patients who underwent percutaneous coronary intervention using 3rd-generation drug-coated stents and coronary artery bypass grafting, according to the two-year follow-up data. Methods. The results of surgical and endovascular revascularization strategies were compared in 140 patients with ischemic heart disease and multivessel coronary disease after previously successfully performed stenting of a clinically dependent artery using 3rd-generation drug-coated stents for acute coronary syndrome without the ST segment elevation based on the results of a two-year follow-up. Results. There were no statistically significant differences in clinical, demographic and operational characteristics between the groups, except for the number of smoking patients, wich was significantly higher in the PCI group. In the PCI group, there was a statistically significant difference in the frequency of repeated revascularizations and the combined MACCE point. Discussion. The obtained results showed the advantage of CABG in a group of patients with previously successfully performed PCI of the clinically dependent artery for non -STEMI and multi-vascular lesions. Conclusion. In patients with coronary artery disease and multivascular lesions of the coronary bed, who had successfully underwent stenting of the clinical-dependent artery using stents of the 3rd generation with drug coating for acute coronary syndrome without the ST segment elevation, and intermediate severity of lesions on the SYNTAX scale when performing full functional revascularization by coronary artery bypass grafting or stenting, there are no differences in the indicators of cardiovascular mortality, myocardial infarction, acute cerebrovascular disease, frequency of return of the clinic angina pectoris, with the exception of the frequency of repeated revascularization and composite MACCE points, which was statistically significantly higher in the group of stenting.

Aim. To assess the long-term results of different approaches to treating patients with non-ST-segment elevation acute coronary syndrome (NSTE ACS) and multivessel coronary artery disease (MVCAD). Subjects and methods. A total of 150 patients with NSTE ACS, in whom coronary angiography revealed MVCAD, were examined. The patients were divided into 3 groups according to the selected treatment policy: 1) percutaneous coronary intervention (PCI) (n=91 (60.6%)); 2) coronary artery bypass grafting (CABG) (n=40 (26.6%)); and 3) only medical treatment (n=9 (6%)). The mean follow-up was 27.6±3.5 months. Results. The medical treatment policy in this patient sample demonstrates the worst results, with the majority of cardiovascular events developing in the hospital period. PCI in patients with NSTE ACS and multiple coronary atherosclerosis has a number of objective limitations in this patient sample, leading to suboptimal treatment outcomes Conclusion. The use of CABG or PCI as a myocardial revascularization technique in patients with NSTE ACS and MVCAD is characterized by a comparable satisfactory survival in the hospital and long-term follow-up periods. 12% of patients do not receive revascularization due to the extremely high risk from any of coronary blood restoring methods, which results in very many deaths largely occurring during the hospital period.

The feasibility of dual antiplatelet therapy as early as possible in patients with ST-segment elevation acute coronary syndrome, where percutaneous coronary intervention is recommended, has been proven: it improves treatment outcomes by reducing the risk of adverse ischemic events, including stent thrombosis and myocardial infarction.This article provides a detailed analysis of the evidence data and current recommendations on the validity and timing of dual antiplatelet therapy for acute coronary syndrome. The emphasis is made on the controversy regarding the early dual antiplatelet therapy in non-ST-segment elevation acute coronary syndrome. The rationale for using dual antiplatelet therapy only after coronary angiography and determining the revascularization strategy is described, which should increase the accessibility of coronary artery bypass graft surgery for patients.

Background A sizeable number of patients with a diagnosis of non-ST segment elevation acute coronary syndrome show non-obstructive coronary artery disease. In this study we assessed whether differences in vascular and cardiac autonomic function exist between non-ST segment elevation acute coronary syndrome patients with obstructive or non-obstructive coronary artery disease. Methods and results Systemic endothelium-dependent and independent vascular dilator function (assessed by flow-mediated dilation and nitrate-mediated dilation of the brachial artery, respectively) and cardiac autonomic function (assessed by time-domain and frequency-domain heart rate variability parameters) were assessed on admission in 120 patients with a diagnosis of non-ST segment elevation acute coronary syndrome. Patients were divided into two groups according to coronary angiography findings: (a) 59 (49.2%) with obstructive coronary artery disease (≥50% stenosis in any epicardial arteries); (b) 61 (50.8%) with non-obstructive coronary artery disease. No significant differences between the two groups were found in both flow-mediated dilation (5.03 ± 2.6 vs. 5.40 ± 2.5%, respectively; P = 0.37) and nitrate-mediated dilatation (6.79 ± 2.8 vs. 7.30 ± 3.4%, respectively; P = 0.37). No significant differences were also observed between the two groups both in time-domain and frequency-domain heart rate variability variables, although the triangular index tended to be lower in obstructive coronary artery disease patients (30.2 ± 9.5 vs. 33.9 ± 11.6, respectively; P = 0.058). Neither vascular nor heart rate variability variables predicted the recurrence of angina, requiring emergency room admission or re-hospitalisation, during 11.3 months of follow-up. Conclusions Among patients admitted with a diagnosis of non-ST segment elevation acute coronary syndrome we found no significant differences in systemic vascular dilator function and cardiac autonomic function between those with obstructive coronary artery disease and those with non-obstructive coronary artery disease.
