Дополнительным фактором, вносящим вклад в развитие патологии сосудов и сердца, служит дефицит витамина D; в то же время данных о взаимосвязи уровня витамина D с состоянием миокарда у пациентов с ХСН недостаточно.</p><p>Целью исследования было оценить уровень витамина D в плазме крови у лиц с ХСН, изучить его влияние на морфофункциональное состояние миокарда.</p><sec><title>Материалы и методы</title><p>Материалы и методы. Обследовано 124 пациента с ХСН I–II функционального класса и 16 лиц группы контроля без ХСН. Всем пациентам проводилась оценка уровня общего витамина D (25(ОН)D total методом иммуноферментного анализа) и эхокардиография на аппарате Logiq Р5 (США).</p></sec><sec><title>Результаты</title><p>Результаты. Средний уровень 25(ОН)D в плазме крови пациентов с ХСН составил 16,6 (10,9; 23,7) нг/мл и был ниже (р = 0,01), чем в группе контроля — 42,1 (27,8; 49,6) нг/мл. Все пациенты с ХСН были разделены по уровню 25(ОН)D в плазме крови согласно центильному распределению на группу I (LQ0–UQ25) с уровнем 25(ОН)D до 10,9 нг/мл, группу II (LQ25–UQ75) с уровнем 25(ОН)D 10,9–23,7 нг/мл и группу III (LQ75–UQ100) с уровнем 25(ОН)D 23,7 нг/мл и выше. Уровень систолического артериального давления (САД) в группе I был выше, чем в группе III (р = 0,04), а в группе контроля — ниже, чем во всех группах пациентов с ХСН (р &lt; 0,05). Размеры аорты и ее отделов, левого предсердия, показатели конечного систолического объема, конечного диастолического объема (КДО), толщина передней и задней стенок левого желудочка (ЛЖ) в систолу были больше в группе I, по сравнению с группой II и III и с контрольной группой. Установлены отрицательные корреляции между уровнем 25 (ОН)D в плазме крови с показателями КДО (R = –0,24; р = 0,03), ударного объема (R = –0,28; р = 0,01), размером аорты на уровне аортального клапана (АК) (R = –0,39; р = 0,0002), восходящего отдела аорты (R = –0,31; р = 0,02) и дуги аорты (R = –0,41; р = 0,002), а также с толщиной передней стенки ЛЖ (R = –0,36; р = 0,004) и задней стенки ЛЖ в систолу (R = –0,27; р = 0,01) во всей группе пациентов с ХСН. Также нами установлена положительная корреляция между уровнем САД и размером аорты на уровне АК (R = 0,44; = 0,00003) и восходящего отдела аорты (R = 0,36; р = 0,006).</p></sec><sec><title>Выводы</title><p>Выводы. Установленные нами ассоциации уровня витамина D в плазме крови с морфофункциональным состоянием миокарда указывают на отрицательное влияние сниженного уровня витамина D на сократительную функцию миокарда, размеры аорты и размеры передней и задней стенок ЛЖ.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Objective</title><p>Objective. Chronic heart failure (CHF) is the most common complication of cardiovascular system diseases associated with unfavorable prognosis. Vitamin D deficiency is an additional factor contributing to the development of cardiovascular pathology. Current evidence on the relationship between vitamin D and the state of the myocardium in patients with CHF is insufficient. The aim of the study was to assess the plasma level of vitamin D in CHF patients and to evaluate its impact on the morphological and functional state of the myocardium.</p></sec><sec><title>Design and methods</title><p>Design and methods. The study involved 124 patients with CHF I–II functional class and 16 control subjects without CHF. In all patients, vitamin D level was assessed (25(ОН)D total by ELISA) and echocardiography on the apparatus Logiq Р5 (USA) was performed.</p></sec><sec><title>Results</title><p>Results. The average plasma level of 25 (OH)D in CHF patients was 16,6 (10,9; 23,7) ng/mL that was significantly lower (p = 0,01) than in the control group 42,1 (27,8; 49,6) ng/mL. All patients with CHF were divided by the plasma level of 25 (OH)D according to centile distribution into group I (LQ0–UQ25) with level of 25 (OH)D 10,9 ng/ml, group II (LQ25–UQ75) with level 25 (OH)D 10,9–23,7 ng/ml, and group III (LQ75–UQ100) with level of 25 (OH)D 23,7 ng/ml and above. Systolic blood pressure (SBP) was significantly higher in group I than in group III (p = 0,04), and in the control group this value was significantly lower than in all groups of CHF patients (p &lt; 0,05). Dimensions of the aorta and its sections, left atrium, parameters of end-systolic volume, end-diastolic volume (EDV), thickness of the anterior and posterior left ventricle wall during systole were significantly higher in group I as compared to group II, III and the control group. There is a negative correlation between the plasma level of 25 (OH)D and EDV (R = –0,24; p = 0,03), systolic output (R = –0,28; p = 0,01), dimensions of the aorta at aortal valve (AV) (R = –0,39; p = 0,0002), ascending aorta (R = –0,31; p = 0,02) and aortic arch (R = –0,41; p = 0,002), parameters of anterior (R = –0,36; p = 0,004) and posterior left ventricular wall thickness during systole (R = –0,27; p = 0,01) in all patients with CHF. Also, there is a positive correlation between SBP and aorta dimensions at the AV level (R = 0,44; р = 0,00003) and ascending aorta (R = 0,36; р = 0,006).</p></sec><sec><title>Conclusions</title><p>Conclusions. Found association of vitamin D plasma levels with structural and functional state of the myocardium indicates the negative impact of vitamin D deficiency on myocardial contractile function, dimensions of the aorta and anterior and posterior walls of the left ventricle.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>витамин D</kwd><kwd>хроническая сердечная недостаточность</kwd><kwd>эхокардиография</kwd><kwd>миокард</kwd></kwd-group><kwd-group xml:lang="en"><kwd>vitamin D</kwd><kwd>chronic heart failure</kwd><kwd>echocardiography</kwd><kwd>myocardium</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Булгак А.
