Изучить наличие и характер взаимосвязей между эхокардиографическими параметрами функции миокарда левого желудочка (ЛЖ) и показателями углеводного обмена, а также оценить возможность применения метода спекл-трекинговой эхокардиографии (СТЭ) в ранней диагностике субклинической дисфункции миокарда ЛЖ при сахарном диабете (СД) 2 типа у лиц без клинических проявлений сердечно-сосудистых заболеваний.</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В исследование было включено 120 человек обоего пола в возрасте от 45 до 75 лет. Пациенты были разделены на три группы: 1 — с СД 2 типа (n=53), 2 — с предиабетом (n=20), 3 — контрольная, без нарушений углеводного обмена (n=47). Всем участникам была проведена трансторакальная двухмерная эхокардиография с оценкой стандартных показателей систолической и диастолической функции сердца, а также количественных параметров СТЭ. Кроме того, всем участникам проводилась лабораторная диагностика нарушений углеводного обмена, включавшая определение в крови уровня глюкозы натощак, гликированного гемоглобина (HbA1c), инсулина, С-пептида и расчет индекса инсулинорезистентности.</p></sec><sec><title>Результаты</title><p>Результаты. У пациентов с СД 2 типа в сравнении с контрольной группой статистически значимо отличались показатели диастолической функции миокарда: меньшее значение отношения соотношения скорости трансмитрального потока в раннюю и позднюю диастолу (E/А), отношение скорости трансмитрального потока в раннюю диастолу к скорости движения митрального кольца (Е/е'), скорости движения митрального кольца (е') и более высокое время изоволюмического расслабления (IVRT), а также время замедления ранне-диастолического потока (DT). По результатам многофакторного анализа, независимым предиктором развития диастолической дисфункции оказался не только СД 2 типа, но и предиабет. Фракция выброса ЛЖ (по Simpson) у всех участников исследования сохранена. У пациентов с СД 2 типа в сравнении с контролем, по данным СТЭ, выявлено снижение глобальной продольной деформации (ГПД), увеличение апикальной ротации, а также скручивания миокарда ЛЖ. В многомерном регрессионном анализе уровень HbA1с имел обратную связь с ГПД и явился независимым предиктором снижения ГПД, а достоверным предиктором изменения скручивания, апикальной и базальной ротации была длительность СД. При этом ГПД и скручивание ЛЖ имели высокую чувствительность в определении снижения Е/А, е'/а', е', повышения IVRT.</p></sec><sec><title>Заключение</title><p>Заключение. У пациентов с СД 2 типа без клинических проявлений сердечно-сосудистых заболеваний выявлены субклинические признаки диастолической дисфункции по типу замедленной релаксации ЛЖ; систолическая дисфункция при сохраненной фракции выброса ЛЖ проявилась снижением ГПД, а также увеличением апикальной ротации и скручивания миокарда ЛЖ, выявленных с помощью СТЭ. Выраженность бессимптомной систоло-диастолической дисфункции ЛЖ была ассоциирована со степенью тяжести нарушения обмена глюкозы и длительностью СД.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Aim</title><p>Aim. To study the relationship between echocardiographic parameters of left ventricular (LV) function and carbohydrate metabolism indicators, as well as to evaluate value of speckle-tracking echocardiography (STE) in the early diagnosis of subclinical LV dysfunction in type 2 diabetes (T2D) in individuals without clinical manifestations of cardiovascular disease (CVD).</p></sec><sec><title>Material and methods</title><p>Material and methods. The study included 120 people of both sexes aged 45 to 75 years. Patients were divided into three following groups: 1 — with T2D (n=53), 2 — with prediabetes (n=20), 3 — control, without carbohydrate metabolism disorders (n=47). All participants underwent transthoracic two-dimensional echocardiography with an assessment of standard systolic and diastolic parameters, as well as quantitative STE indicators. In addition, all participants underwent laboratory diagnostics of carbohydrate metabolism disorders, which included the determination of blood fasting glucose, glycated hemoglobin (HbA1c), insulin, and C-peptide, as well as insulin resistance index estimation.</p></sec><sec><title>Results</title><p>Results. In patients with T2D, in comparison with the control group, diastolic function parameters were significantly different as follows: a lower value of early to late diastolic transmitral flow velocity (E/A) ratio, the ratio of early transmitral flow velocity to early diastolic mitral annulus velocity (E/e'), mitral annular velocity (e') and higher isovolumic relaxation time (IVRT), as well as early diastolic flow deceleration time (DT). According to multivariate analysis, not only T2D, but also prediabetes was an independent predictor of diastolic dysfunction. The Simpson's LV ejection fraction was preserved in all study participants. In patients with T2D, in comparison with the control, according to STE, a decrease in global longitudinal strain (GLS), an increase in apical rotation, and also LV twist were revealed. In a multivariate regression analysis, the HbA1c level had an inverse relationship with GLS and was an independent predictor of its decrease, and the T2D duration was a significant predictor of twisting changes, apical and basal rotation. At the same time, GLS and LV twist had a high sensitivity in determining the decrease in E/A, e'/a', e', as well as the increase in IVRT.</p></sec><sec><title>Conclusion</title><p>Conclusion. In patients with T2D without CVD manifestations, sub-clinical signs of diastolic dysfunction were revealed, such as delayed LV relaxation; systolic dysfunction with preserved ejection fraction was manifested by a decrease in GLS, as well as an increase in apical rotation and LV twisting, identified by STE. The severity of asymptomatic LV systolic-diastolic dysfunction was associated with the severity of glucose metabolism disorders and T2D duration.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>сахарный диабет 2 типа</kwd><kwd>диабетическая кардиомиопатия</kwd><kwd>хроническая сердечная недостаточность</kwd><kwd>спекл-трекинговая эхокардиография</kwd><kwd>глобальная продольная деформация</kwd><kwd>скручивание и ротация миокарда</kwd></kwd-group><kwd-group xml:lang="en"><kwd>type 2 diabetes</kwd><kwd>diabetic cardiomyopathy</kwd><kwd>heart failure</kwd><kwd>speckle tracking echocardiography</kwd><kwd>global longitudinal strain</kwd><kwd>myocardial twist and rotation</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">Cosentino F, Grant PJ, Aboyans V, et al. 2019 ESC Guidelines on diabetes, pre-diabetes, and cardiovascular diseases developed in collaboration with the EASD.
