摘　　要：目的探讨冠心病患者经皮冠状动脉介入治疗(PCI)前后右室功能的短期改变。方法测量冠心病(CHD)组和健康对照组的右室常规超声指标,以及Tei指数、TA Sa、TAPSE及心尖四腔观右室面积变化分数(RVFAC),比较CHD组术前、术后和健康对照组之间的差异。结果与健康对照组相比,CHD组术前TA Sa、TAPSE下降及Tei指数增高,术后较术前TAPSE增高及Tei指数下降,术后与健康对照组相比TA Sa、TAPSE下降及Tei指数增高,差异均有统计学意义(P<0.05)。TA Sa与TAPSE呈正相关(r=0.641,P<0.01),Tei指数与TA Sa、TAPSE呈负相关(r=-0.542,P<0.01;r=-0.570,P<0.01)。结论 TA Sa、TAPSE及Tei指数相关性良好,能有效评价冠心病患者PCI前后右室功能的短期改变。Objective To observe the changes of right ventricular function in patients with coronary artery heart disease（ CHD） before and after percutaneous coronary intervention（ PCI）. Methods TA Sa,Tei index,TAPSE and RVFAC were evaluated in 77 patients with CHD before and after PCI. Additionally,TA Sa,Tei index,TAPSE and RVFAC were evaluated in 64 health volunteers. Results Before intervention,TA Sa and TAPSE of patients with CHD were less than those of the health volunteers,Tei index was more than those of the health volunteers,and the differences were statistically significant（ P〈0. 05）. After intervention,TAPSE of patients with CHD was more than before,Tei index of patients with CHD was less than before,and the differences were statistically significant（ P〈0. 05）; TA Sa and TAPSE of patients with CHD were less than those of the health volunteers,Tei index was more than those of the health volunteers,and the differences were statistically significant（ P〈0. 05）. TA Sa had a close correlation with TAPSE（ r = 0. 641,P〈0. 01）,TA Sa and TAPSE had a close correlation with Tei index（ r =- 0. 542,P〈0. 01; r =- 0. 570,P〈0. 01）. Conclusion TA Sa and TAPSE have a close correlation with Tei index,playing a significant role in estimating the short-term changes of right ventricle function before and after PCI in patients with CHD.
