[Clinical and functional tests for pulmonary hypertension and cor pulmonale in chronic pulmonary berylliosis and plutonium-induced pulmonary sclerosis].

Berylliosis and plutonium pneumosclerosis patients appeared to have two types of pulmonary hypertension: hypervolemic and hypertonic ones. Hypervolemic type of pulmonary circulation was revealed in 31.7% of berylliosis patients and in 53.8% of plutonium pneumosclerosis patients. Hypertonic type of pulmonary circulation was seen in 68.3% of berylliosis patients and in 46.2% of plutonium pneumosclerosis patients mainly at stages II and III. Berylliosis and plutonium pneumosclerosis patients are subjects for early pulmonary hypertension--moderate in most patients at stage I and high at stage II and III. Pulmonary hypertension is a main pathogenetic factor underlying chronic corpulmonale formation.
