ABSTRACT
Objective:
To evaluate the changes of right ventricular function in patients with pneumoconiosis in different stages using three-dimensional speckle-tracking imaging (3D-STI) .Methods:
In June 2020, 114 pneumoconiosis patients were selected as subjects, including 45 patients in stage â pneumoconiosis group, 36 patients in stage â ¡ pneumoconiosis group and 33 patients in stage â ¢ pneumoconiosis group. Fifty healthy subjects were enrolled and served as control group. The longitudinal strain (LS) , radial strain (RS) and circumferential strain (CS) of free wall middle and basal segment of right ventricular were collected and compared. The right ventricular global longitudinal strain (GLS) , right ventricular global circumferential strain (GCS) , right ventricular ejection fraction (RVEF) , right ventricular global radial strain (GRS) , the rate of fractional area change (FAC) , the tricuspid valve systolic peak velocity (TVSPV) and the pulmonary artery systolic pressure (PASP) of each subject in the groups were collected and compared by 3D-STI.Results:
The LS and RS of the right ventricular basal segment of patients in stage â ¡ pneumoconiosis group were significantly lower than those of control group (P<0.0125) . The LS, CS, RS of the right ventricular basal segment and RS of right ventricular middle segment of patients in stage â ¢ pneumoconiosis group were significantly lower than those of control group (P<0.0125) . The LS, CS and RS of the right ventricular basal segment of patients in stage â pneumoconiosis group were significantly higher than those of stage â ¢ pneumoconiosis group (P<0.0125) , and the RS of the right ventricular basal segment of patients in stage â ¡ pneumoconiosis group was significantly higher than that of stage â ¢ pneumoconiosis group (P<0.0125) . The levels of RVEF and GLS of patients in stage â ¡ and stage â ¢ pneumoconiosis group were significantly lower than those of control group (P<0.0125) , while the levels of PASP were significantly higher than that of control group (P<0.0125) . The levels of FAC and TVSPV of patients in stage â ¢ pneumoconiosis group were significantly lower than those of control group (P<0.0125) . The levels of RVEF, GLS and FAC of patients in stage â pneumoconiosis group were significantly higher those that of stage â ¢ pneumoconiosis group (P<0.0125) , and the PASP level was significantly lower than that of stage â ¢ pneumoconiosis group (P<0.0125) . The FAC level of patients in stage â ¡ pneumoconiosis group was significantly higher than that of stage â ¢ pneumoconiosis group (P<0.0125) .Conclusion:
Patients with pneumoconiosis could experience a decline in right ventricular function at an early stage. The 3D-STI can accurately detect the GLS, GRS, GCS and hemodynamic changes of the right ventricular and evaluate the right ventricular function comprehensively and objectively. 3D-STI is of great significance for the early detection of right ventricular dysfunction in patients with pneumoconiosis.Palavras-chave
