or interventricular artery stenting. The presence of the relevant residual stenoses of the circumflex and right coronary arteries increases the possibility of the aggravated IHD progressing especially by the end of the fourth year of observation. CONCLUSION The disbalance of the local contractility of anterior, inferior and inferolateral left ventricle walls in the course of aggravated IHD is connected with the CA residual stenoses presence and forwards the decrease in global systolic-diastolic function of the left ventricle. The final results can serve as a foundation for optimization of recommendations for performing PCI on the patients with multivessel disease of CA.Introduction Hypertension is the most common cardiovascular disease (CVD) and a major cause of premature death. Study of age/gender-related and social aspects of the disease, and the assessment of the efficacy of antihypertensive treatment are essential elements of the epidemiological monitoring of hypertension and support a reasonable approach to planning further therapeutic and preventive interventions.Objective Assess the prevalence of hypertension in the working-age population, examine the relationship between hypertension patterns and level of education of respondents taking into account age, gender, and the main aspects of lifestyle.Materials and Methods The study included industrial workers who underwent a routine medical examination in September-November 2015. A total of 2432 subjects (59% males and 41% of females) were surveyed. GLPG0187 cell line The study design is cross-sectional, analytic. Methods used anonymous questionnaire surveys using the WHO STEPS questionnaire, anthropometric measurements, BP measurement. Qund, patients with higher education had a lower prevalence of hypertension, significantly higher awareness of the disease and efficacy of the treatment than those who had secondary or primary school education. Overall, the study confirmed that the sample of industrial workers could be a reliable source for monitoring hypertension. The significant gender differences and an independent protective effect of the level of education were identified in the epidemiology of hypertension, which should be taken into account in further studies.OBJECTIVE To assess possibilities of contrast echocardiography with quantitative evaluation of myocardial perfusion in patients with previous Q-wave myocardial infarction. MATERIALS AND METHODS We examined 15 men (42-72 years) with coronary artery disease and previous myocardial infarction, and pathological Q-wave in 2 or more ECG leads. Quantification of left ventricular (LV) myocardial perfusion was performed by calculating of the ultrasound signal tissue intensity from the LV myocardial segments during intravenous administration of the ultrasound contrast agent (SonoVue). The Tissue intensive curve (TIC) analysis was done in the end-diastolic period before and on the fourth cardiac cycle after applying the "flash". Changes in the intensity of myocardial perfusion (A4, dB) was estimated as the difference between the intensity values of the ultrasound signal in the myocardial segment during the period of filling the contrast bubbles on 4-th cardiac cycle and before applying the «flash». Measurements were performed in 16 segments of the LV. A contrast cardiac magnetic resonance imaging (contrast MRI) was performed in order to verify the LV scar. Fibrotic changes of 50% of myocardial wall or more were considered as signs of post-infarction scar. RESULTS The dynamics of perfusion and scar presence in 240 myocardial segments were evaluated. The median A4 was 1 dB (range, -20 to 10 dB). MRI revealed 82 of 240 segments with the large-focal scar. The effectiveness of the diagnostic test (quantitative contrast perfusion echocardiography with A4 assessment) to detect myocardial scar was investigated. ROC curve analysis showed good model quality, AUC=0,787 (0,730-0,837); sensitivity 82.9%; specificity 75.3%; p less then 0.01. The cut-off point for A4 was -1. CONCLUSION A new approach to quantitative contrast assessment of perfusion allows to identify perfusion disorders with high efficiency in patients with previous Q-wave myocardial infarction.OBJECTIVE Assess time and possible predictors of restenosis after the implantation of first- and second-generation coronary stents and bare metal stents (BMSs) in patients with stable coronary artery disease after elective coronary stenting. MATERIALS AND METHODS From 2010 to 2014, 3,732 (2,897 males, 60 [53; 68] years old) patients with stable exertional angina of functional class I-III underwent coronary stenting. From 2014 to 2017, 1,487 (1,173 males and 314 females) patients returned. Repeat coronary angiography was performed in 699 patients. RESULTS A total of 644 first-generation stents, 5,321 second-generation stents, and 473 BMSs were implanted. During the control coronary angiography, contrasting was repeated for 193 first-generation stents, 899 second-generation stents, and 77 BMSs. Restenosis (stenosis of 50 % or more in the previously stented segment) was detected in 28 (14 % of angiographic control) first-generation drug-eluting stents, 94 (10 %) second-generation drug-eluting stents, and 21 (27 %) BMSs. Patients with BMS restenosis returned significantly earlier than patients with restenosis of the first- and second-generation drug-eluting stents (11 [6, 27] months vs. 32 [11; 48]) months and 24 [12; 42] months, respectively; p25 mm.RELEVANCE Diastolic dysfunction occurring at hypertension, obesity, diabetes, or treatment with doxorubicin tends to prevail in all patterns of chronic heart failure. Lack of effective therapy forces to look more into the metabolic processes in cardiomyocytes. OBJECTIVE Assess energy metabolism in cardiomyocytes and changes in titin, a giant myofibril protein that responsible for their elasticity. MATERIAL AND METHODS The study model was cardiomyopathy occurring after the 4-week administration of doxorubicin (2 mg/kg weekly). Diastolic dysfunction was identified by echocardiography and catheterization with the simultaneous measurement of pressure and volume of the left ventricle (LV). RESULTS The levels of adenine nucleotides and phosphocreatine in the heart of animals treated with doxorubicin differed little from the normal values, but lactate levels were increased manifold. A 50% increase in the level of titin phosphorylation was detected, which correlated (r = 0,94) with a nearly twofold increase in the share of a more elastic N2BA-isoform of this protein.
