摘　　要：目的应用实时三维超声心动图(RT-3DE)与二维斑点追踪技术(2D-STE)评估甲状腺功能减低症(以下简称甲减)患者左房功能。方法选取我院收治的甲减患者52例(研究组)和同期健康成人62例(对照组),观察两组及研究组治疗前后常规超声心动图、RT-3DE及2D-STE检测指标的差异,分析促甲状腺素(TSH)与RT-3DE和2D-STE指标的相关性。结果两组常规超声心动图参数比较差异均无统计学意义。RT-3DE检查显示,研究组治疗前后左房主动射血分数(LAAEF)、左房收缩期纵向应变(LASct)均高于对照组,左房被动射血分数(LAPEF)、左房管道期纵向应变(LAScd)和左房储备期纵向应变(LASr)均低于对照组,差异均有统计学意义(均P<0.05);研究组治疗后LAPEF、LAScd和LASr均高于治疗前(均P<0.05),LASct低于治疗前(P<0.05)。2D-STE检查显示,研究组治疗后各节段舒张早期应变率(SRe)和收缩期应变率(SRs)均高于治疗前(均P<0.05);研究组治疗前各节段舒张晚期应变率(SRa)均高于对照组,SRe和SRs均低于对照组,差异均有统计学意义(均P<0.05)。研究组治疗后各节段SRa均高于对照组,SRe和SRs低于对照组,差异均有统计学意义(均P<0.05)。TSH与LAAEF呈正相关,与LAPEF和左房中间段SRe绝对值均呈负相关(均P<0.05)。结论甲减患者左房储存功能下降,左房泵功能、管道均有所损伤,RT-3DE和2D-STE可为临床治疗提供参考依据。Objective To apply real-time three-dimensional echocardiography(RT-3DE)and two-dimensional speckle tracking echocardiography(2D-STE)in assessing the left atrial function of patients with hypothyroidism.Methods Fiftytwo cases of hypothyroidism(study group)and 62 healthy adults(control group)in our hospital were selected,and the differences in the detection indexes of conventional echocardiography,RT-3DE and 2D-STE between the two groups and in the study group before and after treatment were observed.The correlation between thyroid stimulating hormone(TSH)and RT-3DE and 2D-STE indicators were analyzed.Results There were no statistically significant difference in the conventional echocardiographic parameters between the two groups.RT-3DE showed that LAAEF and LASct in the study group were higher than those in the control group before and after treatment,and that LAPEF,LAScd and LASr were lower than those in the control group,and the differences were statistically significant(all P<0.05).LAPEF,LAScd and LASr in the study group after treatment were higher than those before treatment(all P<0.05),and LASct was lower than that before treatment(P<0.05).2D-STE showed that the strain rate of early diastolic period(SRe)and the strain rate of systolic period(SRs)of each segment in the study group after treatment were higher than those before treatment(all P<0.05),the strain rate of late diastolic period(SRa)of each segment in the study group was higher than that of the control group,and both SRe and SRs were lower than those of the control group.The differences were statistically significant(all P<0.05).After treatment,SRa of each segment in the study group was higher than that of the control group,while SRe and SRs were lower than those of the control group,and the differences were statistically significant(all P<0.05).TSH was positively correlated with LAAEF,and negatively correlated with LAPEF and the absolute value of SRe in the middle segment of the left atrium(all P<0.05).Conclusion In patients with hypothyroidism,the s
