摘要
Objective: To investigate right ventricular function in patients with pneumoconiosis, and to provide a basis for quantitative diagnosis and treatment of pneumoconiosis in clinical practice. Methods: A total of 43 patients with pneumoconiosis who were hospitalized consecutively in Shijiazhuang Prevention and Treatment Center for Occupational Diseases from May 2015 to May 2016 were enrolled, and according to the stage of pneumoconiosis, they were divided into stage I group with 16 patients, stage II group with 14 patients, and stage III group with 13 patients. A total of 16 healthy subjects were enrolled as control group. Echocardiography was performed and the relevant parameters were recorded, i.e., right ventricular transverse diameter (RVTD), tricuspid annular plane systolic excursion (TAPSE), and right ventricular myocardial performance index(Tei index). Results: There were significant differences in Tei index and TAPSE between all groups (P 0.05) and between the stage I group and the stage II group in terms of TAPSE (P>0.05). Right ventricular Tei index was negatively correlated with TAPSE (r=-0.547,P<0.05). Conclusion: A combination of right ventricular Tei index and TAPSE can be used for early quantitative evaluation of right ventricular function in patients with pneumoconiosis.
