Диастолическая функция характеризуется наиболее ранними изменениями в миокарде желудочков, нежели нарушения их сократимости, и может использоваться в алгоритме профилактических мероприятий по предупреждению фатальных сердечно-сосудистых событий, в том числе у работающих на промышленных предприятиях.</p><p>Цель исследования — оценить показатели диастолической функции правого желудочка у работников угледобывающей промышленности юга Кузбасса.</p></sec><sec><title>Материалы и методы</title><p>Материалы и методы. В условиях периодического медицинского осмотра обследованы 337 человек, не имеющих заболеваний лёгких и ишемической болезни сердца, из которых 206 работников угольных шахт юга Кузбасса и 131 работник угольных разрезов, в возрасте от 40 до 55 лет (средний возраст шахтёров — 46,12±0,36 года, работников разрезов — 46,98±0,34 года, р=0,107). На ультразвуковой системе «Vivid E9» фирмы-производителя General Electric всем обследуемым проводилась оценка структурно-функционального состояния сердца.</p></sec><sec><title>Результаты</title><p>Результаты. Диастолическая дисфункция в виде снижения отношения транстрикуспидальных потоков менее единицы выявлена у 22,5% шахтёров с артериальной гипертензией и 2,6% без неё (р=0,00001), у работников разрезов — у 12,3% и у 8,3% соответственно (р=0,071). Снижение отношения тканевых допплеровских потоков движения трикуспидального кольца было выявлено у 89,9% шахтёров с артериальной гипертензией и 81,2% без неё (р=0,083), у работников разрезов данный показатель также не отличался (68,4% и 60,3% соответственно, р=0,337), но между шахтёрами и работниками разрезов различия оказались достоверны (р=0,0012 у обследованных с артериальной гипертензией, р=0,0015 — без неё). </p><p>На основании проведённого корреляционного анализа выявлено, что на развитие нарушения диастолической функции правого желудочка у работников угольной промышленности оказывают влияние не только общепринятые факторы и сопутствующая артериальная гипертензия, но и длительный стаж работы в подземных условиях у шахтёров.</p></sec><sec><title>Заключение</title><p>Заключение. На развитие диастолической дисфункции правого желудочка у шахтёров оказывали влияние стаж работы в подземных условиях, наличие артериальной гипертензии, снижение продольной деформации левого желудочка, уменьшение жизненной ёмкости лёгких и нарушение диастолической функции левого желудочка. У работников угольных разрезов выявлены ассоциации показателей диастолической функции правого желудочка с наличием артериальной гипертензии, повышенными значениями индекса курильщика, индекса Кетле, окружности талии, индекса относительной толщины стенок левого желудочка, снижением продольной деформации левого желудочка и объёма форсированного выдоха за 1 секунду и нарушением диастолической функции левого желудочка.</p></sec></abstract><trans-abstract xml:lang="en"><sec><title>Introduction</title><p>Introduction. Diastolic function is characterized by the earliest changes in the ventricular myocardium, rather than violations of their contractility, and can be used in the algorithm of prophylactic measures to prevent fatal cardiovascular events, including in people working at industrial enterprises.</p><p>The objective of the study was to assess the indices of diastolic function of the right ventricle in workers of the coal mining industry in the South of Kuzbass.</p></sec><sec><title>Materials and methods</title><p>Materials and methods. Under the conditions of a periodic medical examination, we surveyed 337 people without lung diseases and coronary heart disease, of which 206 workers of coal mines in the South of Kuzbass and 131 workers of open pit mines, aged from 40 to 55 years (the average age of the miners was 46.12±0.36 years old, of the workers at open pit mines was 46.98±0.34 years, p=0.107). On the ultrasound system "Vivid E9" manufactured by General Electric, all examined persons underwent an assessment of the structural and functional state of the heart.</p></sec><sec><title>Results</title><p>Results. Diastolic dysfunction in the form of a decrease in the ratio of transtricuspid flows less than one was revealed in 22.5% of the miners with arterial hypertension and in 2.6% of the subjects without it (p=0.00001), in the workers of open pit mines there was in 12.3% and 8.3%, respectively (p=0.071). A decrease in the ratio of tissue Doppler flows of tricuspid annulus plane movement was detected in 89.9% of the miners with arterial hypertension and in 81.2% of the subjects without it (p=0.083), this parameter also did not differ among the workers of open pit mines (68.4% and 60.3% respectively, p=0.337), but the differences between the miners and the workers of the open pit mines turned out to be reliable (p=0.0012 in those examined with arterial hypertension, p=0.0015 — without it).</p><p>Based on the conducted correlation analysis, it was revealed that the development of impaired right ventricular diastolic function in coal industry workers was influenced not only by generally accepted factors and concomitant arterial hypertension, but also by long-term work experience in underground conditions in the miners.</p></sec><sec><title>Conclusion</title><p>Conclusion. The development of diastolic dysfunction of the right ventricle in miners was influenced by work experience in underground working conditions, the presence of arterial hypertension, a decrease in the longitudinal deformation of the left ventricle, a decline in the vital capacity of the lungs and impaired diastolic function of the left ventricle. Associations of right ventricular diastolic function indices with the presence of arterial hypertension, increased values of the smoker’s index, Quetelet index, waist circumference, relative wall thickness index of the left ventricle, a decrease in the longitudinal deformation of the left ventricle and forced expiratory volume in 1 second and impaired diastolic function of the left ventricle were revealed in the workers of open pit mines.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>диастолическая дисфункция правого желудочка</kwd><kwd>артериальная гипертензия</kwd><kwd>угольная промышленность</kwd></kwd-group><kwd-group xml:lang="en"><kwd>right ventricular diastolic dysfunction</kwd><kwd>arterial hypertension</kwd><kwd>coal industry</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">Нестеров В.С., Урванцева И.А., Воробьев А.С.
