The assessment of the Nt-proBNP test result in T2DM has its own specifics due to polymorbid pathology (obesity and CKD) and the presence of multidirectional “disturbing” factors. When planning a follow-up program for elderly patients with DM2 and hypertension, the indications for Nt-proBNP screening should be taken into account, and if the result is positive, for an in-depth Echocardiography examination.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель</bold> – определить специфические особенности применения иммунохроматографической полуколичественной методики оценки Nt-proBNP для диагностики хронической сердечной недостаточности (ХСН) у коморбидных пожилых пациентов с СД 2 типа (СД2) во взаимосвязи с показателями клинико-метаболического статуса.</p> <p><bold>Материал и методы. </bold>Исследование выполнено по кроссекционному дизайну. Изучено 97 клинических и лабораторно-инструментальных показателей, включая определение Nt-proBNP полуколичественным методом, в выборке 50 коморбидных пожилых пациентов с СД2. Выделены группы по пороговому значению Nt-proBNP 450 пг/мл. Проанализированы взаимосвязи и значимость различий переменных в группах, в том числе средних значений биомаркеров достижения целей лечения СД2 и структуры медикаментозной терапии.</p> <p><bold>Результаты. </bold>Выявлены высокая распространенность коморбидной патологии (артериальной гипертензии (АГ) – 90%, ожирения – 74%, дислипидемии – 72%) и высокая доля недостижения терапевтических целей участников, сопоставимые в группах Nt-proBNP. Определена значимая ассоциация между группой Nt-proBNP и ранее установленной стадией ХСН (χ2 = 6,4; р = 0,041), а также положительная корреляция с показателем соотношения скоростей трансмитрального кровотока в раннюю и позднюю диастолу Е/А (r = 0,309; р = 0,003). Получены косвенные доказательства высокой чувствительности полуколичественной оценки Nt-proBNP для диагностики ХСН ранних стадий.</p> <p><bold>Выводы.</bold> Большинство (72%) коморбидных пожилых пациентов с СД2 имеют уровень Nt-proBNP выше общепопуляционного порогового значения 125 пг/мл и нуждаются в верификации диагноза ХСН. Оценка результата теста Nt-proBNP при СД2 имеет специфику, обусловленную полиморбидной патологией (ожирение и ХБП) и наличием разнонаправленных «возмущающих» факторов. При планировании программы диспансерного наблюдения пожилых пациентов, имеющих СД2 и АГ, следует учитывать показания к скринингу Nt-proBNP, а при положительном результате – к углубленному эхоКГ-обследованию.</p></trans-abstract><kwd-group xml:lang="en"><kwd>old age</kwd><kwd>type 2 diabetes mellitus</kwd><kwd>N-terminal brain-promoting natriuretic peptide</kwd><kwd>chronic heart failure</kwd><kwd>comorbid pathology</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>пожилой возраст</kwd><kwd>сахарный диабет 2 типа</kwd><kwd>N-терминальный промозговой натрийуретический пептид</kwd><kwd>хроническая сердечная недостаточность</kwd><kwd>коморбидная патология</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Panchal K, Lawson C, Chandramouli C, et al.
