Study covered 426 miners aged 40-54 years with previously diagnosed occupational respiratory diseases due to dust (246 patients with chronic occupational obstructive bronchitis, 98 with anthracosilicosis and 82 with chronic dust nonobstructive bronchitis). 315 (73.9%) examinees out of 426 with lung diseases due to dust demonstrated chronic cor pulnmonale. Considering high share of this complication, the authors used Bayes method to create a method to diagnose predisposition towards chronic cor pulmonale in patients with dust lung diseases through respiratory failure, concomitant coronary heart disease and arterial hypertension, blood groups ABO, MN and P, some structural and functional parameters of heart: myocardium weight index, relative wall thickness index and left ventricle sphericity index, average lung artery pressure. Increasing number of analyzed factors that directly influence chronic cor pulmonale development and selecting additional markers help to improve forecasting of the complication.
