В исследование включены 158 женщин, проживающих в промышленном центре Крайнего Севера с размещением крупных предприятий металлургического профиля (группа наблюдения), и 65 женщин, проживающих в аналогичных климато-географических условиях, но без размещения промышленных предприятий (группа сравнения). Эхокардиографическое исследование проводилось с измерением структурных и допплерографических параметров сердца на ультразвуковом сканере экспертного класса «Vivid q».</p></sec><sec><title>Результаты</title><p>Результаты. В группе наблюдения были выше, чем в группе сравнения, значения миокардиальных индексов для митрального (0,55 ± 0,09 против 0,48 ± 0,07; р = 0,005) и трикуспидального (0,57 ± 0,10 против 0,48 ± 0,06; р = 0,001) колец. Повышение концентрации никеля в крови ассоциировано с повышением времени изоволюмического расслабления митрального атриовентрикулярного кольца (р = 0,0001) и систолического давления в лёгочной артерии (р = 0,00002). С повышением концентрации мышьяка в крови ассоциировано повышение давления наполнения левого желудочка и конечного диастолического размера левого желудочка (р = 0,0001), диаметры правого желудочка и правого предсердия (р = 0,0001), а также скорость позднего диастолического наполнения правого желудочка и миокардиального индекса для трикуспидального атриовентрикулярного кольца (р = 0,0001).</p></sec><sec><title>Ограничения исследования</title><p>Ограничения исследования.

The study included one hundred fifty eight women living in the industrial center of the Far North with the location of large metallurgical enterprises (observation group) and 65 women living in similar climatic and geographical conditions, but without the location of industrial enterprises (comparison group). An echocardiographic study was carried out with the measurement of structural and doppler parameters of the heart on an expert-class ultrasonic scanner “Vivid q”.</p></sec><sec><title>Results</title><p>Results. In the observation group the values of myocardial performance indices (MPI) values for mitral annulus (0.55 ± 0.09 vs. 0.48 ± 0.07, p=0.005) and tricuspid annulus (0.57 ± 0.10 vs. 0.48 ± 0.06, p=0.001) were higher than in the comparison group. A gain in the concentration of nickel in the blood is associated with an increase in isovolumic relaxation time (IVRT) of the mitral atrioventricular ring (p=0.0001) and systolic pressure in the pulmonary artery (p=0.00002). An increase in the concentration of arsenic in the blood is associated with an increase in the filling pressure of the left ventricle (E/Em) and end diastolic diameter of the left ventricle (EDD LV) (p=0.0001), the diameters of the right ventricle (RV) and right atrium (RA) (p=0.0001), and rate of late diastolic filling of the RV and MPI of the tricuspid atrio-ventricular ring (p=0.0001).</p></sec><sec><title>Limitations</title><p>Limitations. This study did not include middle aged and elderly women, and also did not include male patients and did not include the population of other territories except the Far North. </p></sec><sec><title>Conclusion</title><p>Conclusion. The revealed changes in echocardiographic parameters indicate subclinical dysfunctions of the myocardium of the left and right ventricles, affecting both systolic and diastolic function in residents of the industrial city of the Far North, living under the influence of nickel and arsenic.</p><p>Compliance with ethical standards.
