| 中文摘要:目的 评价Tei指数在儿童轻症病毒性心肌炎心功能评估中的价值。方法 选择笔者医院收入的轻症病毒性心肌炎患者50例，将其纳入观察组，另选取同期来笔者医院健康体检者50例，纳入对照组，分别进行超声检查，于心尖四腔心切面测量二尖瓣口血流频谱E峰及A峰，计算VE/VA，并采用Simpson法测量计算左心室射血分数（EF），于心尖五腔心切面采取血流频谱数据，计算Tei指数，并将两组数据进行比较分析。结果 观察组及对照组两组的EF值及VE/VA差异无统计学意义（P>0.05）；观察组Tei指数为0.38±0.06，对照组Tei指数为0.34±0.03，观察组Tei指数与对照组Tei指数比较，差异有统计学意义（P<0.01）结论 Tei指数操作方便、计算简单，可敏感的反应心室收缩或舒张功能的变化，可用于评估儿童轻症病毒性心肌炎患者的心脏整体功能，临床应用价值高。 |

| Abstract:Objective To evaluate the heart function of children with mild viral myocarditis by Tei index.Methods Fifty patients with mild viral myocarditis were recruited by strict inclusion criteria named observation group, and 50 normal subjects were named control group. All of them were performed with routine echocardiography, the parameters of Tei index, ejection fraction(EF), VE/VA were calculated and analyzed.Results Compared with the control group, there was no sinificant difference in EF of children with mild viral myocarditis(63.4%±6.3% vs 65.5%±5.1%, P>0.05), and there was no statistical difference in VE/VA between the two groups(1.57±0.26 vs 1.64±0.21,P>0.05). Tei index of patients in observation group increased significantly compared with control group,(0.38±0.06 vs 0.34±0.03,P<0.01).Conclusion Tei index can be considered as a simple, convenient index to evaluate the change of heart systolic or diastolic function of patient with mild viral myocarditis. It can be regard as a sensitive method with high clinical value. |
