摘　　要：目的:探讨应用超声脉冲多普勒(pulsed wave doppler,PW)联合组织多普勒成像(tissue Doppler imaging,TDI)技术评价甲状腺功能亢进性心脏病患者的右心室功能的临床价值。方法:选取2011年10月至2014年7月收治的甲状腺功能亢进症患者81例,分为单纯甲亢组(48例)和甲亢性心脏病组(简称甲亢心组,33例),并选取同期健康体检者35例为正常对照组。应用PW测量心脏三尖瓣口舒张期峰值血流速度E峰;应用TDI在心尖四腔切面的三尖瓣环间隔处以及侧壁处测量收缩期峰值速度(Sm)、舒张期峰值速度(Em),计算E/Em值。结果:与对照组相比,甲亢心组侧壁处的Sm无明显变化,差异无统计学意义(P>0.05),而Em明显降低,E/Em明显升高,与对照组比较,差异有统计学意义(P<0.05);单纯性甲亢组与对照组比较,侧壁Sm增高,差异有统计学意义(P<0.05),而Em、E/Em无明显变化,差异无统计学意义(P>0.05)。单纯甲亢组、甲亢心组和对照组三尖瓣环间隔处的Sm、Em、E/Em比较,差异无统计学意义(P>0.05),见表2。结论:PW联合TDI技术用于甲亢心患者右心室功能的评价,效果良好。Objective：To investigate the clinical value of the application of pulsed wave （PW） combined with tissue Doppler imaging （TDI） in evaluating the right ventricular function in hyperthyroid heart disease （hyperthyroidism heart）.Methods：81 cases of hyperthyroidism hospitalized in our hospital from October 2011 to July 2014 were divided into the hyperthyroidism group （48 cases ） and the hyperthyroid heart disease group （33 cases）.Besides, 35 cases chosen from those who received physical examination during the same period to form the control group .Diastolic tricuspid peak flow velocity（E）was measured by PW.Systolic tricuspid annular veloci-ty（Sm）and diastolic tricuspid annular velocity（Em）were measured by TDI and the ratio of E to Em were calculated.Results：Compared with the control group, Sm of lateral wal of the hyperthyroid heart disease group was of no significant change （ P 〉0.05）, but Em decreased and E/Em increased significantly （ P 〈0.05）;Sm of lateral wal of the hyperthyroidism group increased significantly （ P 〈0.05）, but there was no significant dif erence for Em, and E/Em （ P 〉0.05）.The dif erence between Sm, Em, and E/Em of the hyperthyroidism group, the hyperthyroid heart disease group and the control group was not significant （ P 〉0.05）.Conclusion：PW combined with TDI can be used to evaluate the right ventricular function in hyperthyroid heart disease , which is of good ef ect .
