Известно, что низкая концентрация L-гомоаргинина (гАрг) в плазме свидетельствует о прогрессировании сердечно-сосудистых заболеваний. Однако связь уровня гАрг в крови с риском сердечно-сосудистых осложнений (РССО) при артериальной гипертензии (АГ) не охарактеризована. Цель исследования заключалась в определении и сравнительном анализе уровней гАрг в качестве объективного лабораторного показателя РССО у пациентов с АГ. Материалы и методы. Обследовано 60 пациентов обоего пола с АГ, находившихся на стационарном лечении в клиниках ФГБОУ ВО ПСПбГМУ им. И. П. Павлова Минздрава России, в том числе с умеренным (n = 12), высоким (n = 16) и очень высоким (n = 32) РССО. В образцах плазмы оценивали комплекс биохимических показателей, включая уровень гАрг. Группа сравнения включала 30 регулярных доноров сопоставимого возраста. Результаты. Обнаружен существенно пониженный уровень гАрг у пациентов в сравнении со здоровыми лицами (р &lt; 0,001). Выявлены отрицательные корреляции показателя гАрг с эхокардиографическими показателями, характеризующими степень гипертрофии левого желудочка сердца. По мере увеличения РССО уровень гАрг прогрессивно снижался (р = 0,042). При ROC-анализе площадь под кривой с 95-процентным доверительным интервалом составила 0,860 (0,787–0,933). Порог отсечения для гАрг составил ≤ 1,69 мкМ при чувствительности 72,0 % и специфичности 93,3 %. Заключение. Уровень гАрг в плазме характеризует экспрессию и ферментативную активность белка аргинин: глицинамидинотрансферазы в различных тканях. Содержание гАрг в крови ниже 1,69 мкМ может расцениваться в качестве интегрального лабораторно-диагностического маркера высокого РССО. Требуются дальнейшие исследования прогностического и диагностического значения гАрг в качестве лабораторного критерия РССО при прогрессировании сердечно-сосудистых заболеваний и их терапии.</p></abstract><trans-abstract xml:lang="en"><p>Background. Low plasma concentration of L-homoarginine (hArg) is associated with the progression of cardiovascular disease. However, the association between plasma hArg and cardiovascular complications in hypertension is not established. Objective. To assess and compare hArg levels as a biomarker of cardiovascular risk in hypertension. Design and methods. We included 60 hypertensives with moderate (n = 12), high (n = 16) and very high (n = 32) cardiovascular risk. Blood plasma tests including hArg were assessed. The control group included 30 age-matched regular donors. Results. The level of hArg was signiﬁcantly lower in hypertensives compared to ocontrols (р &lt; 0,001). There were negative correlations between hArg and echocardiography parameters of left ventricular hypertrophy. In the higher cardiovascular risk groups hArg was lower (р = 0,042). ROC-analysis showed AUC 0,860 (95 % conﬁdence interval 0,787–0,933) with the threshold for hArg ≤ 1,69 µM, sensitivity 72,0 % and speciﬁcity 93,3 %. Conclusion. The hArg plasma level is associated with the expression and enzyme activity of the protein arginine: glycinamidinetransferase in various tissues. The hArg level ≤ 1,69 µM can be considered a cumulative laboratory biomarker of high cardiovascular risk. Further studies of prognostic and diagnostic role of hArg are needed.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>артериальная гипертензия</kwd><kwd>гомоаргинин</kwd><kwd>сердечно-сосудистый риск</kwd><kwd>энергетический метаболизм</kwd><kwd>клиническая биохимия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>hypertension</kwd><kwd>homoarginine</kwd><kwd>cardiovascular risk</kwd><kwd>energy metabolism</kwd><kwd>clinical biochemistry</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Работа выполнена в рамках выполнения государственного задания.</funding-statement><funding-statement xml:lang="en">The study was conducted within the framework of the Governmental Task.</funding-statement></funding-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Российское кардиологическое общество.
