Longitudinal deformation of the left ventricle and the left atrium in workers of railway transport with arterial hypertension

Abstract

The research objective was in studying and evaluating the indicators of longitudinal deformation of the left ventricle and the left atrium in persons with arterial hypertension (AH), and also in persons with risk factors, but without AH, workers of railway transport.Materials and methods. The workers of railway transport under research are: 45 patients with AH, 35 people with risk factors, but without AH and 20 healthy volunteers. All the people under research were exposed the transthoracal echocardiography on ultrasonic Philips iE 33 system (Holland) including two-dimensional impulsive wave tissue Doppler echocardiography.Results. The decrease of a systolic velocity of a fibrous ring of the mitral valve in the region of septal and lateral segments in both groups is observed in comparison with the control. In studied groups deterioration of a diastolic function and significant decline of indicators of global longitudinal deformation of a left ventricle and the left atrium in comparison to healthy people are also registered. Depression of segmental deformation of a left ventricle in both groups has a chaotic character. The more the index of mass of a myocardium of a left ventricle, the lower indicators of global deformation are; the more the index of volume of the left atrium, the lower indicators of deformation of the left atrium are.Conclusion. Depression of diastolic and segmental systolic functions of a left ventricle of workers of railway transport is registered both with AH and without AH, but with risk factors that are reflected in indicators of longitudinal deformation of a left ventricle and a left atrium.
