摘　　要：目的应用M型超声心动图定量分析煤尘肺患者的三尖瓣环收缩期位移(TAPSE)变化情况,并探讨其评价右心室收缩功能的价值。方法选取2021年5月至2022年6月60例于萍乡市第三人民医院接受检查并确诊的60例煤尘肺患者作为尘肺组,另外,选取同时期于本院进行常规体检的50名健康者作为参照组。比较不同组别受试者、不同尘肺分期和肺功能分型患者右心室面积变化率(RVFAC)、右心室整体长轴应变(GLS)、TAPSE,并采用Pearson相关分析煤尘肺患者RVFAC、GLS、TAPSE之间的关系。结果尘肺组RVFAC、GLS均低于参照组,TAPSE短于参照组,差异有统计学意义(P<0.05)。不同尘肺分期患者RVFAC、GLS、TAPSE比较差异有统计学意义(P<0.05);尘肺分期Ⅲ期患者RVFAC、GLS低于Ⅰ、Ⅱ期,Ⅱ期低于Ⅰ期,Ⅲ期患者TAPSE短于Ⅰ、Ⅱ期,Ⅱ期短于Ⅰ期,差异有统计学意义(P<0.05)。不同肺功能分型尘肺患者RVFAC、GLS、TAPSE比较差异有统计学意义(P<0.05);混合型患者RVFAC、GLS低于限制型、阻塞型、正常型,且限制型低于阻塞型、正常型,阻塞型低于正常型,混合型患者TAPSE短于限制型、阻塞型、正常型,且限制型短于阻塞型、正常型,阻塞型短于正常型,差异有统计学意义(P<0.05)。Pearson相关分析结果显示,TAPSE分别与RVFAC、GLS均呈正相关(r>0,P<0.05)。结论煤尘肺患者TAPSE明显缩小,且随着患者病情的加重TAPSE明显缩小,TAPSE可以反映煤尘肺的病情和肺功能情况,能够作为评价右心室收缩功能的有效指标。Objective M-mode echocardiography was used to quantitatively analyze the changes of tricuspid annular systolic displacement(TAPSE)in patients with coal pneumoconiosis,and to explore its value in evaluating right ventricular systolic function.Methods 60 patients with coal pneumoconiosis who were examined and diagnosed in The Third People's Hospital of Pingxiang City from May 2021 to June 2022 were selected as the pneumoconiosis group,50 normal patients who underwent routine physical examination in our hospital at the same time were selected as the reference group.The right ventricular area change rate(RVFAC),the right ventricular global long-axis strain(GLS),and TAPSE in different groups of subjects,different pneumoconiosis stages and lung function types were compared and analyzed,and the relationship between RVFAC,GLS and TAPSE in patients with coal pneumoconiosis was analyzed by Pearson.Results The RVFAC and GLS in pneumoconiosis group were lower than those in reference group,TAPSE was shorter than that in reference group,and the differences were statistically significant(P<0.05).There were significant differences in RVFAC,GLS and TAPSE among patients with different stages of pneumoconiosis(P<0.05);the RVFAC and GLS in stageⅢwere lower than those in stageⅠandⅡ,and stageⅡwas lower than stageⅠ,and TAPSE in stageⅢwas shorter than that in stageⅠandⅡ,and stageⅡwas shorter than stageⅠ,and the differences were statistically significant(P<0.05).There were significant differences in RVFAC,GLS and TAPSE among pneumoconiosis patients with different pulmonary function types(P<0.05);the RVFAC and GLS in mixed type were lower than those in restricted type,blocking type and normal type,and restricted type was lower than blocking type and normal type,blocking type was lower than normal type,and TAPSE in mixed type was shorter than those in restricted type,blocking type and normal type,and restricted type was shorter than blocking type and normal type,blocking type was shorter than normal type,and the differe
