Coalworker’s pneumoconiosis – Symptoms

Both CWP and mild complicated CWP are often asymptomatic or only affect lung function slightly. When symptoms do occur, shortness of breath and chronic cough are the most common. Progression to PMF is marked by lung dysfunction, pulmonary hypertension, and cor pulmonale.

Both CWP and mild complicated CWP are often asymptomatic or only affect lung function slightly. When symptoms do occur, shortness of breath and chronic cough are the most common. Progression to PMF is marked by lung dysfunction, pulmonary hypertension, and cor pulmonale. Unlike silicosis, patients with CWP do not appear to have a substantial increased risk for tuberculosis, but coal miners may experience significant silica dust exposure, and therefore the accompanying risks. CWP is associated with a variety of autoimmune abnormalities, including rheumatoid arthritis (see Caplan's syndrome below) and scleroderma.
