Current Guidelines

The worldwide morbidity and mortality burden of cardiovascular disease (CVD) is overwhelming and caused by increasing life expectancy and an epidemic of risk factors, including hypertension. Therapeutic options targeting different areas of the renin–angiotensin–aldosterone system (RAAS) to disrupt pathophysiological processes along the cardiovascular continuum are available. Angiotensin-converting enzyme (ACE) inhibitors are first-line treatments for CVD and angiotensin receptor blockers (ARBs) are suitable alternatives. Both ACE inhibitors and ARBs prevent CVD by lowering blood pressure (BP). Additionally, several studies have demonstrated that RAAS blockade can reduce cardiovascular risk beyond what might be expected from BP lowering alone. However, the ARBs are not all equally effective. Telmisartan is a long-lasting ARB that effectively controls BP over the full 24-hour period. Recently, the Ongoing telmisartan alone and in combination with ramipril global endpoint trial (ONTARGET) study showed that telmisartan reduces cardiovascular events in high cardiovascular risk patients similarly to the gold standard ACE inhibitor ramipril beyond BP lowering alone, but with a better tolerability. Based on the results of the ONTARGET and Telmisartan randomized assessment study in ACE intolerant subjects with cardiovascular disease (TRANSCEND) studies, telmisartan is indicated for the reduction of cardiovascular morbidity. This article aims to review current guidelines for the management of CVD and consider key data from clinical trials and clinical practice evaluating the role of telmisartan in CVD.

Background: The prevalence of coronary heart disease (CHD) appears to be high among Chinese Mongolians. MiR-23b has been proven to play a key role in atherosclerosis. The expression and role of miR-23b in the Mongolians at high cardiovascular risk were explored in the present study. Methods: Forty cases of blood samples from the Mongolians at high cardiovascular risk were enrolled in the present study. The expression of miR-23b was quantified by quantitative real-time PCR. To induce monocytes differentiation into macrophages, HP-1 cells were cultured with phorbol 12-myristate 13-acetate. The level of inflammatory markers was determined by the enzyme-linked immunosorbent assay. The interaction between miR-23b and A20 was explored by the dual luciferase reporter assay. Results: The expression of miR-23b in the Mongolian at high cardiovascular risk was higher than that in healthy Mongolian volunteers. Decrease in ATP-binding cassette transporter A1 caused by miR-23b is responsible for TC accumulation in the Mongolian at high cardiovascular risk. MiR-23b enhanced the oxidized low-density lipoprotein (oxLDL)-induced inflammatory response of THP-1 derived macrophage. MiR-23b regulated nuclear factor-κB (NF-κB) pathway through targeting A20. MiR-23b mediated oxLDL-induced inflammatory response of peripheral blood mononuclear cell in the Mongolian at high cardiovascular risk. Conclusion MiR-23b enhanced oxLDL-induced inflammatory response of macrophages in the Mongolian at high cardiovascular risk through the A20/NF-κB signaling pathway, and thus contributing to atherosclerosis.

Изучение свободно циркулирующей митохондриальной ДНК (мтДНК) плазмы крови вызывает растущий интерес. Предполагается, что показатель мтДНК может быть перспективным клиническим биомаркёром оценки рисков течения заболеваний. Целью исследования явилась оценка взаимосвязи количественного показателя мтДНК со стадией заболевания и сердечно-сосудистым риском у пациентов с артериальной гипертензией (АГ). Методы. В исследовании участвовал 70 пациентов, которые были разделены на группу с АГ (n = 51) и контрольную группу практически здоровых пациентов (n = 19). Все пациенты подписали информированное согласие на обследование и обработку данных в рамках научного исследования. Проведена оценка демографических данных, длительности заболевания АГ, факторов риска, наследственности, уровня физической активности, антропометрических данных, лабораторное и инструментальное обследование. Оценка уровня мтДНК проведена методом количественной полимеразной цепной реакции. Использовали фрагмент мтДНК с праймерами FmtMinArc 5'-CTAAATAGCCCACACGTTCCC-3' и RmtMinArc 5'-AGAGCTCCCGTGAGTGGTTA-3'. Результаты. На основании проведенного исследования оценки взаимосвязи количественного показателя мтДНК в крови пациентов с АГ, выявлено, что независимо от стадии заболевания, достоверных различий в показателях уровня мтДНК не выявлено, однако отметим, что количество копий имело тенденцию к увеличению по сравнению с условно здоровыми пациентами. При анализе сердечно-сосудистого риска обнаружено, что количественный показатель мтДНК не зависит от стадии АГ. В то же время уровень мтДНК статистически значимо повышается у пациентов с АГ очень высокого сердечно-сосудистого риска по сравнению с условно здоровыми субъектами: Me (Q1; Q3) - 56731 (42531; 129375) копий/мл против 35156 (18325; 54956) копий/мл соответственно (p = 0,015). Заключение. Уровень мтДНК у пациентов с АГ может явиться маркёром сердечно-сосудистого риска. Учитывая ранее показанную патогенетическую роль уровня мтДНК при остром коронарном синдроме, следует продолжить анализ, чувствительность которого может быть повышена за счет включения количественных показателей содержания ядерной ДНК. Studying cell-free circulating mitochondrial DNA (mtDNA) in blood plasma induces growing interest. It is assumed that an indicator of mtDNA may appear a promising clinical biomarker for assessment of the risks in the course of diseases. The aim of this study was evaluating the relationship between the quantitative indicator of mtDNA in the blood of patients with arterial hypertension (AH) and the stage of the disease and the cardiovascular risk. Methods The study included 70 patients who were divided into a group with AH (n = 51) and a control group of apparently healthy patients (n = 19). All patients signed the informed consent for examination and the processing of personal data as a part of the study. Demographic data, duration of hypertension, risk factors, heredity, physical activity, anthropometric data, results of slaboratory and instrumental examinations were recorded. Concentration of mtDNA was measured by the quantitative polymerase chain reaction. A mtDNA fragment with primers FmtMinArc 5'-CTAAATAGCCCACACGTTCCC-3' and RmtMinArc 5'-AGAGCTCCCGTGAGTGGTTA-3' was used. Results. Studying the relationships between the quantitative indicator of mtDNA in the blood and AH showed that there were no significant differences in the indicators for the level of mtDNA regardless of the AH stage. However, we noted that the number of copies tended to increase in comparison with that in conventionally healthy patients. Analysis of the cardiovascular risk showed that the quantitative indicator of mtDNA did not depend on the stage of hypertension. At the same time, the level of mtDNA was significantly increased in very high cardiovascular risk patients with AH as compared to conventionally healthy subjects: Me (LQ; UQ), 56731.2 (42531.25; 129375.0) copies/ml vs. 35156.00 (18325.00; 54956.00) copies/ml, respectively (p = 0.015). Conclusion. The level of mtDNA in AH patients is a potential a marker for cardiovascular risk as shown by the increase in mtDNA in very high cardiovascular risk patients. Taking into account the previously demonstrated pathogenetic role of the level of mtDNA in acute coronary syndrome, the analysis should be continued. The analysis sensitivity can be increased by inclusion of quantitative indicators for the content of nuclear DNA.

Cardiovascular diseases are one of the main reasons of death in the modern world. Risk factor conception is emphasized in theirs prophylaxis. Nowadays besides risk factors mark out so called «special» population groups in which prophylactic actions school be more aggressive because of high cardiovascular risk. One of such groups is HIV-infected patients. It well known that among them the prevalence of traditional and «new» risk factors is much higher. At the same time in spite of the fact that there are a lot of trials it is lack of evidence about cardiovascular risk factors in HIV-infected patients with the saved immune system function as in «naive», so in antiretroviral treated patients. The aim of our investigation was to evaluate range of express traditional and «new» risk factors in «naive» and antiretroviral treated HIV-infected patients with the saved immune system function.

The article discusses the role of epidemiological studies in the development of preventive programs through the example of the ESSE-RF study. The most interesting and sometimes unexpected research results are discussed. There is an increase in the prevalence of hypertension and obesity, a decrease in the prevalence of smoking, and an extremely high cardiovascular risk. In conclusion, it is noted that the results do provide an opportunity to assess the population health and the priorities of targeted prevention, which is the most effective. Thus, Galen’s statement is confirmed: “Qui bene diagnoscit — bene curat”.
