Introduction.Timely detection of abnormalities of heart contractility is important for physicians, pulmonologists, and occu¬pational pathologists, who provide treatment of this category of patients, because it allows determining optimal approaches to development of prognosis of the disease, peculiarities of treatment policy, and the system of medical and social measures for prevention of the disease.
Purpose. In order to study heart contractility in ore mining industry workers with chronic obstructive pulmonary disease (COPD) of professional etiology an echocardiographic study in post-exposure period was undertaken for the purpose of timely detection of abnormalities in cardiovascular system and development of adequate and effective methods of treatment and prevention of the disease in aforementioned category of patients.
Methods. By means of one- and two-dimensional echocardiography volumetric and linear parameters of left and right com¬partments of the heart, as well as estimates as to their contractility, and total and specific peripheral vascular resistance param¬eters were obtained.
Results. The data on heart contractility in ore mining industry workers with COPD of professional etiology in post-exposure period were analyzed in the article. The results of analysis of the obtained data show that the increase in volumetric and linear parameters of left and right compartments of the heart, decrease of echocardiographic parameters as to heart contractility, formation and pro¬gression of hypertension in pulmonary circulation, as well as significant increase of peripheral vascular resistance are developed in the post-exposure period. Such changes are most developed in workers whose post-exposure period is more than 10 years. Conclusion. The timely detection of abnormalities of heart contractility and their monitoring in the post-exposure period in ore mining industry workers with COPD of professional etiology determines the need to include measures for correction of detected abnormalities in the combination therapy, in order to improve prognosis of the disease and quality of life of afore¬mentioned category of patients.
