Background. Arterial hypertension (AH) remains the leading risk factor associated with cardiovascular diseases (CVDs), cerebrovascular disease and chronic kidney disease. About 70% of patients with AH who are on monotherapy cannot achieve blood pressure (BP) targets, and therefore all quidelines for the management of AH have recently recommended prescribing combination therapy (PCT). In real clinical practice (RCP), there remains significant uncertainty in the effectiveness and rationality of therapy, despite the wide availability of antihypertensive drugs (AHD) and the presence of recommendations for a stepwise approach to prescribing combinations of specific groups of AHD in different clinical situations. Aim. Analyze the real ongoing antihypertensive therapy, including the PCT; international nonproprietary names of drugs and their dosages in RCP; compliance of therapy with clinical recommendations; changing trends in the PCT. Materials and methods. An analysis was carried out of the data from the register of AH, the compliance of treatment in different clinical groups of patients and the achievement of BP and low-density lipoprotein cholesterol targets in the sample of 2019–2022 (n=5012). The prescription of AHD and achievement of targets values were assessed in accordance with current clinical guidelines for the management of AH and hypercholesterolemia. Data from 2010 (n=7782) and 2020 (n=3061) were analyzed to assess the dynamics of prescription of monotherapy and PCT. Results. The greatest increase in the number of AHD was observed in patients with hypertension in combination with coronary heart disease, heart failure, and atrial fibrillation. In a small group of patients with hypertension without other CVDs, the recommended combinations of AHD were not prescribed; preference was given to angiotensin-converting enzyme inhibitors, angiotensin receptor blockers, and β-adrenoblocker (β-AB). PCT mainly differed from the recommended combinations by the wider use of drugs from the β-AB group. The PCT of recommended drugs was highest in patients with hypertension and coronary artery disease – more than 90%, hypertension and heart failure in 56.2%, hypertension and atrial fibrillation – 33.3%, hypertension and chronic kidney desease – 19.6%. Achievement of BP and low-density lipoprotein cholesterol targets was insufficient in all analyzed groups. Among the international nonproprietary names of drugs, the most frequently prescribed are the following: bisoprolol, metoprolol, lisinopril, perindopril, losartan, spironolactone, amlodipine, torasemide, indapamide, hypochlorothiazide, moxonidine. The prescribed daily dosages were closer to the initial recommended ones. By 2020, the prescription of PCT with β-AB and a more uniform prescription of various combinations will come to the fore, while PCT in 2010 is characterized by the presence of one or two leaders combinations. Conclusion. The described features of prescribing AHD partially reproduce clinical recommendations for the management of AH. Differences in therapy provided in RCP may be associated with an attempt to intensify the treatment of hypertension in patients with other concomitant CVDs. At the same time, analysis of combinations and dosages of prescribed drugs suggests the presence of wide opportunities for further escalation of therapy. The presented data can provide insight into current patterns of antihypertensive therapy prescription in patients in RCP and lay the foundation for optimizing therapy in different categories hypertensive patients.

The aim of the research is to analyze correlations between uric acid and cardiovascular risk factors (age, body mass index, waist circumference, total cholesterol and low-density lipoprotein cholesterol levels, glucose) and glomerular filtration Rate in outpatient care hypertensive patients. The research was based on the data of 1285 ambulatory patients from the national register of hypertension. Hyperuricemia was detected in 28,4% of cases. A positive correlation was established between uric acid and waist circumference, body mass index; negative – between uric acid and kidney function deterioration (based on glomerular filtration rate). It was stated that diuretic therapy and smoking are associated with the increase in uric acid serum levels. The study of cardiovascular risk factors frequency in patients with hypertension and hyperuricemia concluded that 80% had more than 1 additional risk factor; combination of ≥3 risk factors occurred in males significantly more often than in females.Acquired data proves that uric acid is closely related to disturbance in metabolic factors, kidney function and diuretic therapy admission, which makes it essential to control its levels in hypertensive patients, as well as to use measures approved by the modern guidelines to decrease uric acid in patients with hyperuricemia.

Аim. To investigate the clinical characteristics and quality of treatment (according to the national guidelines) of patients with arterial hypertension (AH) and chronic kidney disease observed in primary health care. Materials and methods. The study was carried out on the basis of the AH registry data (n=43 133; 20052019 years). Glomerular filtration rate (eGFR) was calculated using the CKD-EPI formula; renal structure and albuminuria were not evaluated. The analysis was performed using the SPSS software (version 22; SPSS Inc). Results. The creatinine level was assessed in 60% of patients, 23.6% of them had decreased eGFR60 ml/ min/1.73 m2. The incidence of co-morbid CVD and type 2 diabetes in patients with hypertension increased markedly with a decrease in eGFR (14 groups): the incidence of coronary artery disease increased 1.8 times (up to 72.5%), myocardial infarction 1.7 times (up to 20.6%), chronic heart failure 2 times (up to 84.0%), atrial fibrillation 10 times (up to 18.3%), history of stroke 3.7 times (up to 15.3%) and type 2 diabetes 2.4 times (up to 32.8%). Achievement of target goals of CV risk factors was not enough: systolic BP less than 50% of patients, triglycerides less than 7%, LDL-C in high and very high CVD risk patients less than 13%. Conclusion. Conducting timely assessment of renal function, drug therapy and lifestyle changes in patients with AH and decreased renal functional could prevent severe kidney damage, the development of CV complications, chronic renal failure and reduce mortality.

AIM:To analyze therapy in patients with arterial hypertension (AH) in 20102020.MATERIALS AND METHODS:Data of hypertensive patients observed in primary health care, entered into the base of hypertension registry for 20102020 years in the whole group (n=44 653) and in a separate subgroup of hypertensive patients in the absence of: ischemic heart disease, a history of myocardial infarction, chronic heart failure (n=20 569).RESULTS:About 80% of hypertensive patients are patients of high and very high risks (from 2010 to 2020, the proportion of very high cardiovascular risk (CVR) increased from 18.1 to 57.3%). The number of hypertensive patients with a history of myocardial infarction increased in 5 times, in 3 times with ischemic heart disease and with chronic heart failure. The number of prescribed drugs increased: mineralocorticoid receptor antagonist (in 5.8 times), loop diuretics (in 7.2) angiotensin receptor blockers (in 3 times), b-adrenoblockers, calcium channel blockers of the dihydropyridine series, thiazide-like diuretics in 2 times. Patients at high and very high risk are more likely reached target blood pressure values. Angiotensin-converting enzyme inhibitors were prescribed in more than 70% of patients with hypertension and the absence of coronary heart disease, chronic heart failure, history of myocardial infarction; the prescription of b-adrenoblockers, angiotension receptor blockers, thiazide-like and loop diuretics increased.CONCLUSION:The proportion of more severe and comorbid patients has increased in observed in primary health care patients with AH over a 10-year period (20102020). This was probably the main factor of increasing antihypertensive therapy and prescribing drugs with additional indications and improving the achievement of target blood pressure in patients with high and very high cardiovascular risk.

The diagnosis of resistant arterial hypertension allows us to single out a separate group of patients in whom it is necessary to use special diagnostic methods and approaches to treatment. Elimination of reversible factors leading to the development of resistant arterial hypertension, such as non-adherence to therapy, inappropriate therapy, secondary forms of arterial hypertension, leads to an improvement in the patient's prognosis. Most patients with resistant hypertension should be evaluated to rule out primary aldosteronism, renal artery stenosis, chronic kidney disease, and obstructive sleep apnea. The algorithm for examining patients, recommendations for lifestyle changes and a step-by-step therapy plan can improve blood pressure control. It is optative to use the most simplified treatment regimen and long-acting combined drugs. For a separate category of patients, it is advisable to perform radiofrequency denervation of the renal arteries.

Диагностика резистентной артериальной гипертонии (РАГ) позволяет выделить отдельную группу больных, у которых необходимо использование специальных диагностических методов и подходов к лечению. Устранение обратимых факторов, приводящих к развитию РАГ, таких как неприверженность терапии, неоптимально подобранная терапия, вторичные формы артериальной гипертонии, приводит к улучшению прогноза больного. Большинство лиц с РАГ следует обследовать для исключения первичного альдостеронизма, стеноза почечной артерии, хронической болезни почек и обструктивного апноэ во сне. Алгоритм обследования больных, рекомендации по изменению образа жизни и поэтапный план терапии позволяют улучшить контроль уровня артериального давления. Желательно использование максимально упрощенной схемы лечения и комбинированных препаратов длительного действия. Отдельной категории больных целесообразно выполнение радиочастотной денервации почечных артерий.

Arterial hypertension (AH), smoking and type 2 diabetes mellitus (T2DM) are the risk factors for the development of myocardial infarction (MI). Their age and gender peculiarities of AH have been studied only in a small number of epidemiological studies. Aim. To study the effect of smoking status and type 2 diabetes on the incidence of MI in men and women with hypertension. Materials and methods. The frequency of MI in men and women with hypertension confirmed by ECG criteria was analyzed depending on age, smoking status and type 2 diabetes. 28 899 hypertensive patients of primary health care in 20102016 were included in the registry of hypertension. Results. In the age of 2544 the number of visits of men and women with hypertension in primary health care was the same, thereafter the ratio of men progressively had been decreasing with the age. The incidence of MI in men with hypertension is significantly higher at all ages than in women (it is 18.3 times higher at the age of 2544). 37.4% of men and 94.8% of women with hypertension have never smoked. The maximum incidence of MI is in middle-aged men (33.0%) and in old-aged women (14.1%) groups, who stopped smoking. MI developed in 3.7 times more often in hypertensive young-age men group who are smoking than in nonsmokers, in those who stopped smoking 13 times more often. The maxima of the curves of the incidence of MI in women with hypertension, based on the smoking status, shifted towards an older age in comparison with men. Percutaneous coronary intervention / Coronary artery bypass graft surgery was performed 2 times more often in hypertensive patients with MI who stopped smoking, compared to nonsmokers. The incidence of MI in hypertensive patients with diabetes in middle-aged men increased by 1.6 times, in women 2.5 times. The higher influence of diabetes mellitus on escalation of MI incidence in women with hypertension than in men persisted until old age. The incidence of MI was 9.8% in never-smoked, 17.7% for smokers and 28.3% for stopped smoking hypertensive patients with diabetes. In the group of patients who never smoked, the risk of MI increased by 1.8 times in the men group and 2.8 in women with AH and DM. However, the odds of MI development in nonsmoking men and women groups with hypertension and diabetes did not significant. Conclusion. Gender-age characteristics of the influence of smoking and type 2 diabetes on the risk of MI in patients with hypertension in primary health care were disclosed. Such risk factors for MI as male gender and smoking are most significant at a young age. In old age, smoking status no longer affects the risk of MI, while the male gender remains important at all ages. The higher incidence of MI in men with hypertension (18.3 times at a young age) compared to women is explained by both the influence of gender and the higher frequency of smoking (12 times). T2DM increases the risk of developing MI in middle age and older. In hypertensive patients with type 2 diabetes, the incidence of MI is maximally increased in middle age in women by 2.5 times; in men 1.6 times. Smoking in patients with AH and type 2 diabetes leads to an additional increase of MI risk (up to 2.8 times).

Артериальная гипертония (АГ), курение и сахарный диабет (СД) 2-го типа – факторы риска развития инфаркта миокарда (ИМ). Их половозрастные особенности при АГ изучены лишь в небольшом количестве эпидемиологических исследований. Цель. Изучение влияния статуса курения и СД 2-го типа на заболеваемость ИМ у мужчин и женщин с АГ. Материалы и методы. Проанализирована частота перенесенного ИМ, подтвержденного ЭКГ-критериями, у мужчин и женщин с АГ в зависимости от возраста, статуса курения и СД 2-го типа. Исследование проведено на выборке данных регистра АГ, включившей 28 899 больных АГ, наблюдавшихся в первичном звене здравоохранения в 2010–2016 гг. Результаты. Число обращений мужчин и женщин с АГ в первичное звено здравоохранения являлось одинаковым в возрасте 25–44 лет, с возрастом доля мужчин прогрессивно уменьшалась. Частота развития ИМ у мужчин с АГ значительно выше во всех возрастах по сравнению с женщинами (в возрасте 25–44 лет выше в 18,3 раза). Никогда не курили 37,4% мужчин с АГ и 94,8% женщин с АГ. Максимальная заболеваемость ИМ 33,0% у мужчин среднего возраста, прекративших курить, у женщин – 14,1% в пожилом возрасте, прекративших курить. В молодом возрасте ИМ у курящих мужчин с АГ развивался в 3,7 раза, у прекративших курить – в 13 раз чаще по сравнению с некурящими. Максимумы кривых заболеваемости ИМ у женщин с АГ в зависимости от статуса курения смещены в сторону более старшего возраста по сравнению с мужчинами. У больных АГ с перенесенным ИМ, прекративших курить, по сравнению с некурящими больными в 2 раза чаще выполнены чрескожная ангиопластика коронарных артерий/коронарное шунтирование. Заболеваемость ИМ при СД у мужчин в среднем возрасте повышалась в 1,6 раза, у женщин с АГ – в 2,5 раза. Более выраженный вклад СД в увеличение заболеваемости ИМ у женщин с АГ по сравнению с мужчинами сохранялись до старческого возраста. В целом по группе больных АГ с СД заболеваемость ИМ составила 9,8% среди никогда не куривших больных, 17,7% – среди курящих и 28,3% – среди больных, прекративших курить. В группе никогда не куривших больных у мужчин с АГ и СД риск ИМ увеличивался в 1,8 раза, у женщин с АГ и СД – в 2,8 раза. Однако отношения шансов вероятности развития ИМ на фоне СД у некурящих мужчин и женщин с АГ статистически значимо не различались. Заключение. Выявлены гендерно-возрастные особенности влияния курения и СД 2-го типа на риск развития ИМ у больных АГ, наблюдающихся в первичном звене здравоохранения. Такие факторы риска ИМ, как мужской пол и курение, максимально проявляют себя в молодом возрасте. В старческом возрасте – статус курения уже не влияет на риск развития ИМ, тогда как мужской пол сохраняет свое значение во всех возрастах. Более высокая заболеваемость ИМ у мужчин с АГ по сравнению с женщинами (в 18,3 раза в молодом возрасте) объясняется как влиянием пола, так и большей частотой курения (в 12 раз). СД 2-го типа повышает риск развития ИМ во все периоды жизни: среднем, пожилом и старческом возрасте. У больных АГ СД 2-го типа повышает заболеваемость ИМ максимально в среднем возрасте – у женщин в 2,5 раза; у мужчин – в 1,6 раза. Курение у больных АГ и СД 2-го типа приводит к дополнительному повышению риска ИМ (до 2,8 раза).

Modern clinical guidelines for the diagnosis and treatment of arterial hypertension (AH) do not provide different treatment strategies separately for men and women. The analysis of gender differences in cardiovascular complications and features of AH therapy contributes to the development of an individualized approach to diagnosis and treatment of hypertension. The purpose of this study is to study the effect of sex on the features of therapy of arterial hypertension and the development of cardiovascular complications. Materials and methods. Data from the register of AH from outpatient hospital and cardiology departments of hospitals of 22 regions of the Russian Federation were analyzed. Data of medical documents of 33 564 patients with AH [(36.2%) men and 21 423 (63.8%) women] were entered into the on-line computer program and were analyzed using the statistical software package STATISTICA 10. Results. Cardiovascular and cerebrovascular diseases are more often diagnosed in men: peripheral artery disease, coronary heart disease, acute coronary syndrome, congestive heart failure, ischemic stroke, dissecting aortic aneurysm. The beginning of development cardiovascular disease in men with elevated blood pressure is already observed at age of 25-44 years, which indicates the need for preventive measures already in adolescence and closer monitoring of treatment at a young age. Conclusion. The study confirmed the role of the male sex as a risk factor for the development of cardiovascular disease in hypertensive men and women with comparable figures of blood pressure in. Identified gender features must be considered when diagnosing patients with AH.

Артериальная гипертония (АГ) - один из ведущих факторов, определяющих высокую смертность населения от сердечно - сосудистых заболеваний (ССЗ) во многих странах мира, включая Россию. Современные клинические рекомендации по диагностике и лечению АГ не предусматривают различные стратегии медикаментозной терапии для мужчин и женщин с АГ. Анализ гендерных и возрастных особенностей медикаментозной терапии у мужчин и женщин с АГ может выявить необоснованное и неоптимальное лечение больных АГ. Целью данного исследования было изучение гендерных особенностей медикаментозной терапии больных АГ, применяемой врачами первичного звена здравоохранения. Материалы и методы. Исследование проводилось методом регистра АГ, который функционирует с 2012 г. Методика его проведения описана ранее [1]. Медицинские данные из амбулаторных карт вводились врачами 53 городских поликлиник и 5 кардиологических диспансеров из 22 регионов Российской Федерации. Из базы данных регистра АГ в исследование вошли данные 33 564 больных старше 18 лет с диагнозом «артериальная гипертония». В регистре АГ использовалась единая компьютеризованная карта, в которую врачи вносили данные пациентов о половой принадлежности, возрасте, росте, массе тела, статусе курения, клиническом уровне артериального давления (АД), лабораторных и инструментальных методов обследования, диагностированных сердечно - сосудистых и цереброваскулярных заболеваниях и коморбидности в соответствии с Международной классификацией болезней 10-го пересмотра [ICD-10], а также о проводимом лечении (антигипертензивная и гиполипидемическая терапия). Результаты и заключение. Выявлены гендерные различия в назначении врачами медикаментозной антигипертензивной терапии (АГТ) у мужчин и женщин с АГ. Одной из причин этих различий, по - видимому, являются особенности клинического течения, связанного с более частым и ранним развитием сердечно - сосудистых и цереброваскулярных осложнений АГ у мужчин, чем у женщин. Так, бета - адреноблокаторы (БАБ) и ингибиторы ангиотензинпревращающего фермента (ИАПФ) чаще назначаются мужчинам с АГ с ишемической болезнью сердца (ИБС), перенесенным инфарктом миокарда (ИМ) и хронической сердечной недостаточностью (ХСН). Женщинам с АГ чаще назначают блокаторы к ангиотензину II (БРА), тиазидные и тиазидоподобные диуретики. Исследование показало неоптимальность лечения больных АГ. В частности, у больных с АГ и ИБС, перенесенным ИМ и ХСН выявлено недостаточное назначение препаратов [ИАПФ/БРА, БАБ, антагонистов минералокортикоидных рецепторов], улучшающих прогноз заболевания. Обращает на себя внимание отсутствие записей в амбулаторных картах о проводимой АГТ у больных АГ всех возрастных категорий: в молодом возрасте - у 9,6%, в старческом возрасте - у 15,1%. Недостаточно назначается гиполипидемическая терапия (статины), несмотря на то, что большинство больных, наблюдаемых в первичном звене здравоохранения, относятся к высокому и очень высокому сердечно - сосудистому риску. Максимально большее назначение статинов наблюдалось у больных АГ с ИБС (50,1%) и перенесенным ИМ (62,7%).

Hypertension is one of the most important risk factors for cardiovascular diseases (CVD) in the world, including Russia. Current Guidelines for the management of arterial hypertension do not include different theatment strategies for men and women. Gender and age analysis of antihypertensive treatmen in men and women could reveal unreasonable and non - optimal treatment in each group. The purpose of this study was to identify the gender features of antihypertensive therapy used by primary care physicians in patients with hypertension. Materials and methods. The study is based on the Arterial Hypertension Registry established in 2012. The methodology of it has been described previously [1]. Medical data from outpatient cards were entered by doctors of 53 city primary care medical centers and 5 cardiology clinics from 22 regions of the Russian Federation. The study included the data of 33 564 patients from 18 years and older with diagnosis of arterial hypertension. Gender, age, height, body weight, smoking status, office blood pressure (BP), laboratory and instrumental examination methods, diagnosed cardiovascular and cerebrovascular diseases and comorbidities in accordance with the International Classification of Diseases of the 10th revision [ICD-10], as well as the treatment (antihypertensive and lipid - lowering therapy) were listed. Results and conclusion. Gender differences in the prescription antihypertensive therapy (AHT) in men and women with hypertension were revealed. Apparently, one of the reasons for these differences is the earlier and more frequent development of cardiovascular and cerebrovascular complications of hypertension in men than in women. Beta - blockers (BB) and angiotensin - converting enzyme inhibitors (ACEi) are more often prescribed to men with hypertension and with coronary artery disease (CAD), myocardial infarction (MI) and chronic heart failure (CHF). Women with hypertension are more often prescribed angiotensin receptor blockers (ARB), thiazide and thiazide - like diuretics. The study also showed non - optimal treatment of patients with hypertension. Insufficient prescription of medication which could improve the prognosis of the disease (ACE inhibitors /ARB, BB, mineralocorticoid receptor antagonist) have been identified in patients with hypertension and CAD, MI, CHF. It is noteworthy that in the some outpatient cards of patients with AH there is no record of AHT prescription: at a young age - in 9.6%, at old age in 15.1% of cards. Despite the fact of high and very high cardiovascular risk of the majority of patients, lipid - lowering therapy (statins) was prescribed insufficiently. The most statin administration was observed in hypertensive patients with coronary artery disease (50.1%) and myocardial infarction (62.7%).

Объединение препаратов с антигипертензивным, гиполипидемическим, гипогликемическим и антиагрегантным действием в одну таблетку существенно повышает приверженность лечению и обеспечивает множественный контроль факторов риска, снижая риск развития сердечно-сосудистых заболеваний и фатальных событий. При этом в настоящее время еще не получены убедительные доказательства, что использование полипилла в кардиологии приводит к большему снижению частоты развития первичных конечных точек (общая смертность, фатальный инфаркт миокарда, острое нарушение мозгового кровообращения и т.д.), чем стандартная стратегия лечения.

Рефрактерная артериальная гипертония (АГ) - особый фенотип АГ, устойчивый к проводимой антигипертензивной терапии. Термины «рефрактерная АГ» и «резистентная АГ» зачастую считают взаимозаменяемыми и используют в отношении АГ, трудно поддающейся лечению. Группа пациентов с рефрактерной АГ, т.е. больных, не достигающих целевых цифр артериального давления на фоне максимальной антигипертензивной терапии, очень мала. Настоящий обзор посвящен сравнению сходных и контрастных черт в определениях, частоте встречаемости, характеристике пациентов, факторах риска и возможных этиологиях.

В настоящем документе продемонстрированы современные представления о состоянии проблемы диагностики и лечения ортостатической гипотензии (ОГ). В нем основное внимание уделяется разработанным алгоритмам диагностики классической ОГ, начальной ОГ и отсроченной ОГ. Описаны необходимые методы для поэтапного проведения дифференциальной диагностики причин ОГ. Проанализированы рекомендации по лечению данного состояния Американской коллегии кардиологов/Американской ассоциации сердца/Общества сердечного ритма и Европейского общества кардиологов. Описаны варианты лечения различных групп пациентов с ОГ.

Objective: To assess effect of antihypertensive (AHT) and CPAP- therapy on inflammatory risk factors of cardiovascular complications- CRP (C-reactive protein) and hsCRP (high-sensitivity CRP) as well as homocysteine in patients with arterial hypertension and obstructive sleep apnea. Design and method: We included 15 male middle-aged patients (41,1 ± 8,5 age) with AH (office BP 152,1 ± 6,6 /89,6 ± 10,1 mmHg), obesity (BMI 35,7 ± 4,6) and severe OSAS (AHI 58,9 ± 24,3), and otherwise healthy (in terms of chronic heart disease, diabetes mellitus, chronic kidney disease, manifested autoimmune or inflammatory disease). CRP, hs-CRP, homocysteine were assessed in the morning, fasting, 3 times: after initial diagnostics, after achievement of target BP levels (office BP 127,8 ± 8,1/ 76,5 ± 5,1 mmHg) 1–2 month of solely on AHT (ACEi and calcium channel blocker – fixed combination of perindopril + amlodipine) and after addition of CPAP-therapy (compliance > 4 h/night) for 3 month. Results: CRP levels didn’t change significantly with the therapy: at baseline 0,35 mg / dl, 0.26 mg /dl on AHT and 0.20 mg/dl - CPAP + AHT. hsCRP levels showed a tendency to decrease from baseline - 4.62 mg /l to 2.65 mg /l – on AHT and 2.21 mg /l on AHT+CPAP-therapy. Homocysteine level at baseline was 12,3 μmol/L, 1 month of AHT - 13,2 μmol/L and when CPAP- therapy was added to AHT level dropped to 8,5 μmol/L l (p < 0,05).Conclusions: In the study levels of CRP were in the range of normal values, whilst hsCRP was elevated at baseline and showed a tendency to decrease on AHT and CPAP-therapy, but did not reach statistical significance. It is planned to continue this study on a large sample of patients. Homocysteine levels, initially and on the AHT were at the boundary values and moderate hyperhomocysteinemia, but with CPAP-therapy showed a significantly decrease of its value to a safe level.
