Ascending aorta wrapping in surgical correction of aortic valve disease
D. Bozhko
Objective: To study the results of surgical treatment of patients with ascending aorta dilatation and aortic valve disease. Methods: Echocardiographic examination was performed in all patients before surgery, within 1 month after surgery, and in the long-term period - once a year. Computed tomography was performed in patients from the main group as a control research method within 1 month after surgery and in the long-term period – once a year. Results: The results of surgical treatment of 255 patients with aortic valve disease and ascending aorta dilatation from 40 to 55 mm in the early postoperative and long-term periods with an average follow-up period of 3 years were analyzed. The wrapping method of the ascending aorta, performed in 93 patients, led to a significant decrease in the ascending aorta diameter from 45.47±2.96 mm to 35.98±3.88 mm, preventing the progression of its dilatation and aneurysm formation. The method showed a lower risk of complications in the early postoperative period compared to ascending aorta replacement. In the long-term follow-up, the frequency of major cardiovascular events and overall survival after aorta wrapping and aorta replacement in combination with correction of the aortic valve pathology did not differ significantly. After aorta wrapping, according to computed tomography, during the observation period, there were no complications from the ascending aorta in the form of dissection, intimal defects, wrap dislocation, aorta kinking; there was no significant calcification of the xenopericardial wrap. Conclusion: Ascending aorta wrapping can be performed as an alternative method of surgical treatment of the ascending aorta dilatation in aortic valve surgery in a certain cohort of patients with good results in the early postoperative and long-term follow-up periods.

D. Goncharik, L. Plashchinskaya, V. Barsukevich, A. Chasnoit, Ye. Rebeko, M. Zakharevsky, O. Kovalenko
The article describes current approaches to the interventional treatment of patients with arrhythmogenic cardiomyopathy (ACM) complicated with paroxysmal sustained ventricular tachycardia (VT). The advantages and disadvantages of two competing methods for mapping and ablation – activation mapping vs substrate mapping – are analyzed. The rationale for the proposed method of VT substrate mapping in ACM and the authors’ own results are presented. The results obtained by the authors make it possible to recommend substrate ablation according to the proposed technique as an invasive first-line therapy for patients with persistent monomorphic VT and ACM.

Application of photomodification of blood using low-intensity optical radiation in the combination treatment of patients with unstable angina
O. Laskina, G. Zalesskaya, N. Mitkovskaya
The in vivo effect of low-intensity optical radiation (LIOR) on the blood of patients with unstable angina (UA) was studied. The integration of LIOR in the combined therapy of patients with UA proved to result in positive changes in the oxygen uptake system. Changes in the absorption spectra of the patients’ blood samples, blood oxygenation characteristics, and the proportion of metabolic products were studied at all stages of light exposure. The absorption of LIOR by the blood was found to lead to its photomodifica tion, which was manifested in changes of the partial pressure of blood gases, the content of oxyhemoglobin and the degree of saturation of hemoglobin with oxygen. LIOR affects the oxygen exchange in the body of patients with UA, changes the delivery and consumption of oxygen by tissues, initiates positive changes in the balance between the production of reactive oxygen intermediates, acting as physiologically active compounds, and their inhibition by antioxidant systems.

Shybekа Nаtallia, Gelis Lyudmila, Rusak Tatsiana
One of the main causes for operative mortality and perioperative complications after coronary artery bypass grafting is myocardial reper fusion injur y following the restoration of the coronar y circulation in the ischemic zone of the myocardium and characterized by myocardial, electrophysiological and vascular dysfunction. In order to identify the diagnostic signs of myocardial reperfusion injury after coronary artery bypass grafting, a prospective study was conducted, which included 89 patients with ischemic heart disease and forthcoming coronary artery bypass grafting either on-pump or off-pump. Postischemic myocardial dysfunction was assessed using transesophageal echocardiography, morphological and functional signs of myocardial reperfusion injury were detected using cardiac magnetic resonance imaging, moreover, the level of highly sensitive troponin, myoglobin, creatine phosphokinase-MB, metalloproteinase-2, and highly sensitive C-reactive protein was measured to assess the contribution of biomarkers to the development of reperfusion injuries. The obtained data allowed us to assess the morphological and functional characteristics of postischemic myocardial dysfunction and identify diagnostic signs of irreversible reperfusion injuries.

ST-elevation myocardial infarction and acute ischemic kidney injury
E.Yu. Brankovskaya, L.V. Kartun, E.V. Hodosovskaya, N.P. Mitkovskaya
The aim of the study was to investigate specific clinical manifestations, homeostasis indices and parameters of the cardiovascular system in patients with acute ST-elevation myocardial infarction (STEMI) and acute ischemic kidney injury. Methods. 173 patients with STEMI participated in the study. The study group consisted of 111 patients with acute ischemic kidney injury associated with myocardial infarction (MI); 62 patients with MI and normal kidney function were enrolled in the comparison group. Clinical, anthropometric, laboratory, and instrumental diagnostic methods were used. Results. Compared with patients of the MI and normal kidney function group, those with MI and acute ischemic kidney injury had a higher average heart rate, required more prolonged vasopressor and/or inotropic therapy, and more frequently developed tachyarrhythmias with adverse prognostic impact and postinfarction aneurysms. The study revealed that patients of the MI and acute ischemic kidney injury group demonstrated more severe dilatation of the left ventricle (LV), more pronounced reduction in myocardial LV contractility according to echocardiography results; they developed multivessel coronary artery disease more frequently. Furthermore, patients of this group had a higher incidence of infarction-associated artery damage located in the proximal segments of major coronary arteries and more frequently developed thrombotic occlusion in the infarction-affected artery. Patients with MI and acute ischemic kidney injury had higher levels of inflammatory, myocardial necrosis, hemostasis and neurohormonal activation markers. Higher concentration of neutrophil gelatinase-associated lipocalin (uNGAL) was observed in patients with MI and acute ischemic kidney injury; moreover, in 14,1% of patients belonging to this group, elevated levels of this marker preceded the diagnostically significant increase in creatinine concentration and decrease in glomerular filtration rate.

Arterial hypertension and atrial fibrillation: molecular genetic aspects of pathogenesis and complex therapy, focus on the renin-angiotensin-aldosterone system
N.V. Bukvalnaya, L.V. Yakubova, V.A. Snezhitskiy
This article is devoted to the effect of the renin-angiotensin-aldosterone system on the development and maintenance of atrial fibrillation on patients with arterial hypertension. It is noted that the adverse effects of the renin-angiotensin-aldosterone system end products, angiotensin II and aldosterone, can be caused not only by their hyperproduction, but also by the activation of the transforming growth factor β1 initiated by them. This cytokine initiates the process of fibrosis in the left atrium, which is a substrate of arrhythmia. The article features the results of multicenter clinical trial demonstrating the effectiveness of angiotensin-converting enzyme inhibitors, angiotensin II receptor blockers and mineralocorticoid receptor antagonists in the prevention of atrial fibrillation. The review includes the analysis of the effect of polymorphic variants of the angiotensin-converting enzyme gene ((I/D) ACE), the angiotensin II receptor gene type 1 ((A1166C) AGTR1), the aldosterone synthase gene (C/T (-344) CYP11B2) and the gene of the transforming growth factor β1 (G/C (+915) TGFB1) on the development of arterial hypertension and atrial fibrillation, as well as on the effectiveness of therapy with renin-angiotensin-aldosterone system blocking drugs.
