Цель: изучить молекулярные эффекты тиотриазолина у пациентов с ишемической болезнью сердца (ИБС). Материалы и методы: у 60 пациентов со стабильной стенокардией напряжения I-III функционального класса сравнивались эффекты тиотриазолина со стандартным режимом терапии (СРТ), учитывая активность уровня основных продуктов свободнорадикального окисления (СРО) и антиоксидантных систем (АОС), протеомный профиль белков. Результаты: через 24 недели на фоне СРТ и тиотриазолина выявлено статистически достоверное увеличение содержания глутатион редуктазы, снижение малонового диальдегида, увеличение частоты выявления экспрессии эндотелиальной липазы, фосфомевалонаткиназы, γ-бутиробетаин гидроксилазы, линолеил-КoA-десатуразы, снижение экспрессии дельта-5 десатуразы. Заключение: тиотриазолин обладает кардиопротекторным действием с антиоксидантным и цитопротекторным эффектами, снижая содержание продуктов СРО, повышая активность ферментов АОС при ИБС. Ключевые слова: тиотриазолин, хроническая ишемическая болезнь сердца, антиоксидантная система, свободно-радикальное окисление, протеомика.

Repetitive quarantines and social restrictions during the coronavirus disease 2019 (COVID-19) pandemic have negatively affected the population health in general, and the control of hypertension (HTN) in particular.Aim. To evaluate the control of HTN in the Russian population during the COVID-19 period based on the results of screening for HTN May Measurement Month 2021 (MMM2021).Material and methods. During May-August 2021, 2491 participants from 11 Russian regions took part in the screening. Participation was voluntary without restrictions on sex. All participants were over 18 years of age. During the screening, blood pressure (BP) was measured three times using automatic and mechanical BP monitors. In addition, a questionnaire was filled out on behavioral risk factors, comorbidities and therapy. HTN was diagnosed with systolic BP ≥140 mmHg and/ or diastolic blood pressure ≥90 mmHg and/or taking antihypertensive therapy. The questionnaire included questions about prior COVID-19, vaccinations and their impact on the intake of antihypertensive drugs.Results. The analysis included data from 2461 respondents aged 18 to 92, of which 963 were men (39,1%). The proportion of hypertensive patients was 41,0%, while among them 59,0% took antihypertensives and 30,9% were effectively treated. In comparison with pre-pandemic period according to MMM2018-2019, the higher proportion of HTN patients in the Russian sample was revealed during MMM2021 (41,0% vs 31,3%, p<0,001) with a comparable proportion of patients receiving antihypertensive therapy (60,7% vs 59,0%, p=0,05) and treatment efficacy (28,7% vs 30,9%, p=0,36). Monotherapy was received in 44,7% of cases, while dual and triple combination therapy — in 30,9% and 14,1%, respectively. The majority of respondents (~90%) did not adjust their antihypertensive therapy during the COVID-19 pandemic.Conclusion. According to HTN screening in Russia, there is persistent ineffective control of HTN, which may be due to both the worsening pattern of behavioral risk factors, limited access to healthcare during COVID-19, and the inertia of physicians and low adherence of patients due to the asymptomatic HTN course in the majority.

Relevance. Among cardiovascular diseases arterial hypertension (AH) in elderly people over 60 years old is the main risk factor for stroke, heart failure, terminal renal failure and lethal outcome. Today hypertension is defined as accelerated aging of the arterial component of the cardiovascular system with developing of remodeling processes due to age. Studies of a molecular phenotype of hypertension in elderly patients with obtaining molecular profiles of biological samples determining the clinical course of hypertension and its classification characteristics are topical nowadays. The aim of the study is to search correlations between structural, functional and molecular diagnostic parameters in patients with AH of Grade 2 of a moderate and high risk. Methods and materials: The study involved patients over 60 years old with a diagnosis of Grade 2, moderate and high risk hypertension (Group 2, n=200), taking into consideration the criteria of inclusion and non-inclusion into the study. The control group (KG, Group 1) included 30 elderly people with no hypertension. Central blood pressure (BP) in the aorta and pressure on the brachial artery were measured, indicators of daily blood pressure monitoring, structural and functional parameters of the heart were evaluated on the basis of echocardiography. There was fulfilled a qualitative proteomic analysis of blood plasma based on time–of–flight mass spectrometry with a laser desorption and ionization and quantitative assessment of the level of proteins in the blood with the help of enzyme immunoassay. Results: There was revealed an increase of the blood concentration of MPO, apoD, HIF1α, TGFβ1, hyaluronidase 1, kininogen 1, fibulin 5 and their significant correlations with LVMM and ACC. Conclusions: There was determined diagnostic molecular profile of blood of elderly patients with AH of Grade 2 and confirmed the involvement of proteins in myocardial and vascular remodeling in elderly patients with AH.
