Cardiac hypertrophy in coalworkers' pneumoconiosis.

Right ventricular hypertrophy in a group of coalworkers.

The prevalence of right ventricular hypertrophy was studied in necropsy material from 215 coalworkers, a group which consisted of 115 men with simple or no pneumoconiosis and 100 with progressive massive fibrosis. Right ventricular hypertrophy was considered to be present if the ratio of the weight of the left ventricle plus septum to that of the right ventricle was less than 2:1. The prevalenc...

The right ventricle and the small pulmonary arteries in coalworkers.

In previous work (Thomas, 1951; James and Thomas, 1956), we have been made aware of some problems of pulmonary heart disease that needed further elucidation. Further consideration of the method of assessment of right ventricular hypertrophy and its relation to emphysema and pneumoconiosis when present, separately or together, was needed. Jaffe (1934), referred to the lesion of pneumoconiosis as...

Cor pulmonale in coal-worker's pneumoconiosis.

Attention has been drawn to the occurrence of pulmonary heart disease in South Wales coalworkers suffering from severe pneumoconiosis. The clinical, radiological, and electrocardiographic features have been described by Thomas (1948) and, assessing right ventricular hypertrophy post mortem by a technique of differential ventricular weighing, he concluded that cardiographic patterns are poor ind...
