A dissection method is used to examine hearts from 202 unselected autopsies, 150 of which are from soft coal workers, in a study of right ventricular hypertrophy in West Virginia coal miners. A definite increase in right ventricular mass is demonstrated in 40% of the miners, with 19% of the miners having definite right ventricular hypertrophy associated with uncomplicated coal workers' pneumoconiosis. The high incidence of right ventricular change is considered significant in the light of the discovery of pulmonary hypertension occurring during light or moderate exercise early in the natural history of the disease.
