To study the changes of the levels of cardiac biomarkers (N-terminal pro-brain natriuretic peptide (NT-proBNP) and high-sensitivity troponin I (hsTnI)) in patients with newly diagnosed multiple myeloma (MM) during programmatic treatment with bortezomib (VCd regimen).</p></sec><sec><title>Material and methods</title><p>Material and methods. This prospective pilot study included patients with a newly diagnosed MM (n=30), who were scheduled for a cycle of chemotherapy including a proteasome inhibitor (bortezomib). All patients underwent standard laboratory (complete blood count, biochemical tests, serum protein electrophoresis), electrocardiography, echocardiography, as well as the level of specific laboratory markers of myocardial dysfunction (NT-proBNP) and injury (hsTnI) was determined immediately before treatment, after 3 and 6 cycles of chemotherapy.</p></sec><sec><title>Results</title><p>Results. The mean age was 63,8±10 years with a slight predominance of men (56,7%, n=17). The patients initially had an increased level of NT-proBNP (316 [75,9; 602,6] pg/mL) with its decrease to 144,0 [102,3; 294,0] pg/ml after 3 cycles and to 109,2 [59,9; 344,5] pg/ml after 6 cycles of chemotherapy. At the MM onset, the mean hsTnI values were 0,06 [0,03; 0,49] ng/mL, whereas after 3 and 6 chemotherapy cycles it accounted for 0,02 [0,01-0,68] and 0,65 [0,02; 1,51] ng/ml, respectively, with the normal range of less than 0,1 ng/ml. Despite this, no statistical significance has been obtained. There were no clinical and/or laboratory signs of heart failure, ischemia, or other non-cardiac causes of elevated NT-proBNP levels in this cohort. Multivariate regression analysis revealed the following significant factors influencing the initial hsTnI level: paraprotein, hemoglobin and erythrocyte sedimentation rate (ESR). The resulting regression model was characterized by a strong correlation (r=0,702, p&lt;0,001).</p></sec><sec><title>Conclusion</title><p>Conclusion. MM and its pathogenetic features such as paraproteinemia may be challenging for NT-proBNP and hsTnI levels assessment in group of interest before treatment. An unreliable assessment of these markers before chemotherapy may lead to incorrect baseline cardiovascular risk stratification and make it difficult for a cardiologist/cardio-oncologist to choose proper management strategy.</p></sec></abstract><trans-abstract xml:lang="ru"><sec><title>Цель</title><p>Цель. Изучение динамики уровней кардиальных биомаркеров — N-концевого фрагмента мозгового натрийуретического пептида (NT-prоBNP) и высокочувствительного тропонина I (hsTnI) — у пациентов с впервые установленной множественной миеломой (ММ) на фоне программного лечения с использованием бортезомиба (режим VCd).</p></sec><sec><title>Материал и методы</title><p>Материал и методы. В проспективное пилотное исследование включены больные с впервые установленным диагнозом ММ (n=30), которым была запланирована курсовая химиотерапия (ХТ) с включением ингибитора протеасом (бортезомиб). Всем пациентам проведены стандартное лабораторное (клинический анализ крови, биохимическое исследование с электрофорезом белков сыворотки крови), инструментальное (электрокардиография, эхокардиографическое исследование) обследование, а также определен уровень специфических лабораторных маркеров дисфункции (NT-prоBNP) и повреждения (hsTnI) миокарда непосредственно перед лечением, после 3 и 6 курсов ХТ.</p></sec><sec><title>Результаты</title><p>Результаты. Средний возраст больных с ММ составил 63,8±10 лет, несколько превалировали мужчины (n=17, 56,7%). У исследуемых пациентов исходно отмечался повышенный уровень NT-proBNP (316 [75,9; 602,6] пг/мл); на фоне терапии выявлено его снижение до 144,0 [102,3; 294,0] пг/мл после 3 курсов, до 109,2 [59,9; 344,5] пг/мл после 6 курсов ХТ. В дебюте онкогематологического заболевания средние значения hsTnI составили 0,06 [0,03; 0,49] нг/ мл, а на фоне 3 и 6 курсов ХТ — 0,02 [0,01-0,68] и 0,65 [0,02; 1,51] нг/мл соответственно, при норме менее 0,1 нг/мл (динамика для обоих маркеров не достигла уровня статистической значимости). Клинических и/или лабораторных признаков хронической сердечной недостаточности, ишемии, других некардиальных причин повышения уровня NT-proBNP в данной выборке больных не наблюдалось. При многофакторном регрессионном анализе выявлены следующие статистически значимые факторы, влияющие на исходный уровень hsTnI: парапротеин, гемоглобин и скорость оседания эритроцитов (СОЭ). Полученная регрессионная модель характеризовалась коэффициентом корреляции r=0,702, что соответствует высокой силе взаимосвязи (p&lt;0,001).</p></sec><sec><title>Заключение</title><p>Заключение. Наличие ММ с учетом патогенетических особенностей заболевания (в частности, парапротеинемии), может являться причиной трудности оценки уровней NT-proBNP и hsTnI в исследуемой группе пациентов до начала специфического лечения. Недостоверная оценка данных серологических маркеров до начала ХТ может способствовать неверной стратификации исходного кардиоваскулотоксического риска и затруднять выбор тактики ведения кардиологом/кардиоонкологом.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>кардиоонкология</kwd><kwd>кардиотоксичность</kwd><kwd>множественная миелома</kwd><kwd>парапротеин</kwd><kwd>биомаркеры</kwd><kwd>натрийуретический пептид</kwd><kwd>тропонин I</kwd></kwd-group><kwd-group xml:lang="en"><kwd>cardio-oncology</kwd><kwd>cardiotoxicity</kwd><kwd>multiple myeloma</kwd><kwd>paraprotein</kwd><kwd>biomarkers</kwd><kwd>natriuretic peptide</kwd><kwd>troponin I</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование выполнено при финансовой поддержке Российского научного фонда (РНФ) в рамках гранта №22-25-00208 "Изучение экспрессии циркулирующих микроРНК-126 и микроРНК-203, ассоциированных биомолекулярных взаимодействий и сердечно-сосудистого ремоделирования в патогенезе кардиоваскулотоксичности ингибиторов протеасом".</funding-statement><funding-statement xml:lang="en">The study was performed with the financial support of the Russian Science Foundation under the scientific project No. 22-25-00208, scientific grant "Assessment of circulating microRNA-126 and microRNA-203 expression, associated biomolecular interactions and cardiovascular remodeling in the pathogenesis of cardiovasculotoxicity of proteasome inhibitors".</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">Firkins J, Hansen L, Driessnack M, Dieckmann N.
