The study found significant decreases in calcium, potassium, sodium, zinc, and vitamin D<sub>3</sub> levels among COVID-19 patients compared to the control group. Zinc and vitamin D<sub>3</sub> levels showed a significant correlation with sex, with males experiencing a decline in zinc levels and females having lower vitamin D<sub>3</sub> levels. The concentration of calcium, sodium, and zinc showed a negative correlation with age, with older patients having the lowest levels. COVID-19 patients with chronic cardiac issues and high blood pressure exhibited the lowest levels of these markers.

Ранее существовавшие или вызванные инфекцией сердечно-сосудистые заболевания ухудшают исходы для пациентов с COVID-19.</p> <p><bold>Материалы и методы. </bold>В образцах сыворотки крови пациентов проводили количественное определение электролитов (Na<sup>+</sup>, K<sup>+</sup>, Ca<sup>++</sup>, Zn) с помощью биохимического анализатора и витамина D<sub>3</sub> с помощью устройства ichroma ii.</p> <p><bold>Результаты. </bold>В исследовании приняли участие 142 пациента с диагнозом COVID-19, включая 35 критических случаев, 53 тяжелых случая, 54 среднетяжелых случая, а также 50 человек в контрольной группе. Возрастная группа с наибольшей распространенностью инфекции составила 50‒69 лет, а наименьшая распространенность наблюдалась среди лиц моложе 30 лет. Исследование выявило значительное снижение уровней кальция, калия, натрия, цинка и витамина D<sub>3</sub> среди пациентов с COVID-19 по сравнению с контрольной группой. Уровни цинка и витамина D<sub>3</sub> продемонстрировали значительную корреляцию с полом: у мужчин наблюдалось снижение уровня цинка, а у женщин ‒ более низкий уровень витамина D<sub>3</sub>. Концентрация кальция, натрия и цинка имела отрицательную корреляцию с возрастом, при этом у пожилых пациентов наблюдалась самая низкая концентрация. У пациентов с COVID-19 с хроническими заболеваниями сердца и высоким кровяным давлением наблюдались самые низкие уровни этих маркеров. Тяжесть заболевания также оказывала пагубное влияние на уровень электролитов, цинка и витамина D<sub>3</sub>, при этом в критических случаях COVID-19 наблюдались самые низкие уровни. Такие осложнения, как сердечная недостаточность, были связаны с более низким уровнем калия, натрия и цинка.</p> <p><bold>Вывод. </bold>Исследование выявило значительную связь между COVID-19 и снижением уровней электролитов, цинка и витамина D<sub>3</sub>. Было обнаружено, что пол и возраст коррелируют с этими маркерами. У пациентов с хроническими сердечно-сосудистыми заболеваниями и высоким кровяным давлением наблюдались самые низкие уровни этих маркеров. Тяжесть заболевания COVID-19 также была связана с более низким уровнем электролитов, цинка и витамина D<sub>3</sub>. Такие осложнения, как сердечная недостаточность, были связаны со снижением уровней калия, натрия и цинка.</p></trans-abstract><kwd-group xml:lang="en"><kwd>COVID-19</kwd><kwd>Cardiovascular</kwd><kwd>Vitamin D3</kwd><kwd>Zinc</kwd><kwd>electrolyte</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>COVID-19</kwd><kwd>сердечно-сосудистые заболевания</kwd><kwd>витамин D3</kwd><kwd>цинк</kwd><kwd>электролиты</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Montezano A.C., Camargo L.L., Mary S., Neves K.B., Rios F.J., Stein R., et al.
