The study was aimed to evaluate the right ventricular function in pneumoconiosis patients by real-time three-dimensional echocardiography. A total of 80 individuals including 44 consecutive pneumoconiosis patients and 36 age- and gender-matched healthy volunteers as controls were prospectively recruited for the study. All the patients underwent two- and three-dimensional echocardiography. Measurements of the right ventricle included tricuspid regurgitation pressure (TRPG), anterior and posterior wall thickness and range of motion (TH1, TH2, M1, M2), right end-diastolic volume and end-systolic volume. The right ventricular ejection fraction (RVEF) was also calculated. The RVEF of healthy volunteers ranged from 50 to 78 %, whereas that of the pneumoconiosis patients varied from 29 to 73 %. An increase in TRPG caused a significant (p = 0.006) decrease in RVEF (by 77.3 %), suggesting the two variables were negatively correlated (r = -0.643, p < 0.01). In comparison with normal, the volume-time curves of the pneumoconiosis patients showed a lower trough. Use of real-time three-dimensional echocardiography provides with added clinical information needed to evaluate right ventricular function in pneumoconiosis patients.
