System of diagnosis of predisposition to the formation of diastolic heart failure in patients with anthracosilicosis and hypertension

Introduction. Anthracosilicosis (AS) is a serious and common occupational disease of workers in the coal industry, and among somatic diseases in miners more oft en than in the General population, there is an arterial hypertension (AH). One of the complications of such diseases is the development of chronic heart failure, and diastolic heart failure precedes the reduction of contractile function.

The aim of the study was to develop a system of diagnosis of predisposition to the formation of diastolic heart failure in patients with AS and AH.

Materials and methods. 71 miners with AC in combination with AH aged 40 to 54 years with preserved systolic function of the left  ventricle (LV) were examined. Determined by: the presence of diastolic dysfunction of the ventricles, the presence and degree of respiratory failure, obesity, blood group AB0, MN and Rh, mass index left  ventricular, thickness of the interventricular septum, posterior wall of LV anterior wall of right ventricle, index of relative wall thickness of LV and the average pressure in the pulmonary artery.

Results. The higher the detection rate of this complication in the combination of AS and AG in patients with respiratory failure, obesity, with an increased index of myocardial mass of left  ventricle, index of relative wall thickness of LV sphericity index, thickening of the walls of the ventricles, increased pressure in the pulmonary artery, having blood group 0 (I), B (III), MM, NN, Rh-, R+. Th e method of predicting the development of diastolic heart failure is as follows: the survey is carried out once, 10 of the above markers are determined, the data are analyzed using a prognostic table.

Conclusions. With the help of the proposed method of predicting the development of diastolic heart failure in miners with AS and AH, it is possible to quickly and with litt le material cost to identify a group of people with a high risk of developing this complication.
