Peculiarities of the clinical course of the postinfarcti on period in the workers of mining production.

Abstract

Objective: to study the features of the clinical course of the post-infarction period in mining workers. 102 patients with mining working experience from 12 to 35 years were examined. The diagnosis of a previous myocardial infarction (MI) was verified on the basis of anamnesis (analysis of medical documentation), if there are signs of cicatricial changes in the myocardium and zones of left ventricular myocardial asynergy on the electrocardiogram (ECG) according to the ultrasound of the heart. All patients underwent general clinical examination according to generally accepted standard criteria. ECG registration was performed in the classical 12 lead systems, as well as in the V3R-V5R at rest state and at the state of the dosed physical activity. The structural and functional state of the heart was examined using the "HDI - 1500" apparatus by a standard procedure. It is established that risk of MI in mining workers with CHD increases over the age of 40 years mainly and after 10 years of work in unfavorable industrial environments. Predictors of HF in post-MI miners are: age over 40 years, a segment-elevation myocardial infarction with ST, a front localization of infarction, complications in acute MI period, especially of cardiac arrhythmias and conductivity.
