摘要
目的：探讨组织多普勒（tissueDopplerimaging，TDI）-Tei指数评价高原性肺水肿治疗前后右心室功能的研究。方法：收集2009年3月至2012年4月收纳确诊的高原性肺水肿住院病例105例．按NYHA分级分为4组．Ⅱ级27例，Ⅲ级26例，Ⅳ级27例，V级25例，取同期健康体检者25例作为对照组。结果：治疗前，右室射血分数（fightven-tricularejectionfraction，RVEF）和高峰充盈率（peakfillingrate，PFR）随着病患严重程度的增高而减少（P〈0．05）．Tei指数随着病患严重程度的增高而增高（P〈0．05）。经过1个疗程后，各个组别的症状均有显著改善．Ⅱ～Ⅴ级组总有效率分别为92．6％（25／27）、92-3％（24／26）、96．3％（26／27）和96．0％（24／25）。RVEF和Tei指数与病程呈现显著的负相关（P〈0．05）。与对照组相比，高原性肺水肿4个级别的病患RVEF、PFR和Tei指数均有显著差异（P〈0．05），经治疗后，Ⅱ和Ⅲ级的PFR改善不明显（P〉0．05），Ⅳ级的RVEF改善不显著（P〉0．05），Ⅱ～Ⅴ级组的Tei指数改善明显（P〈0．05）。结论：应用TDI—Tei指数可以准确、敏感地反映高原性心脏病患者的右心室功能。
Objective To investigate the effect of tissue Doppler imaging （TDI）-Tei index on evaluation of right ventricular function in High Altitude Pulmonary Edema （HAPE） before and after treatment. Methods From March 2009 to April 2012, 105 hospitalized cases of HAPE were collected, and then divided into 4 groups based on NYHA grading. There were 27 ones of grade 11,26 ones of grade Ⅲ, 27 ones of grade 1V and 25 ones of grade V, with 25 health adults involved in the control group. Results Before treatment, the right ventricular ejection fraction （RVEF） and peak filling rate （PFR） decreased significantly as the severity was aggravated, while Tei index increased statistically, with P〈0.05. After treatment, the total effective rates in 4 groups were 92.6%（25/27）, 92.3%（24/26）, 96.3%（26/27） and 96.0%（24/25）. RVEF and Tei index showed significant negative correlations with the course, with P〈0.05. Compared with the control group, the four groups had the RVEF, PFR and Tel index significantly different, with P〈O.05. After treatment, PFR was improved insignificantly for the cases of grade Ⅱ andⅢ, and the same as RVEF for the cases of grade IV, with P〉0.05; Tel index was improved signifi- cantly for the cases in the four experiment groups. Conclusion TDI-Tei index can reflect the right ventricular function of HAPE patient accurately and aptly.
