摘　　要：目的评价Tei指数反映不同类型冠心病(CAD)心功能受损严重情况的价值。方法将85例疑诊或确诊冠心病并接受冠状动脉(冠脉)造影的患者分为对照组、冠脉轻度狭窄组、冠脉重度狭窄组和急性心肌梗死(AMI)组,进行完整超声心动图检查及左室Tei指数测量。结果4组Tei指数分别为0.40±0.06,0.41±0.07,0.48±0.08,0.56±0.15。冠脉重度狭窄组较冠脉轻度狭窄组及对照组均显著上升,AMI组显著高于另外3组,冠脉轻度狭窄组与对照组间差异无统计学意义。结论Tei指数可反映不同类型CAD患者左心室功能受损严重情况。Objective To determine the feasibility of Tei index in evaluating left ventricular cardiac function in patients with different types of coronary artery disease. Methods Eighty five patients who had received CAG were divided into 4 groups： group Ⅰ as the control group, group Ⅱ with coronary artery diameter stenosis ≥ 50% 〈 70%, group Ⅲ with coronary artery diameter stenosis ≥ 70% and group Ⅳ with AMI. Patients in group Ⅱ and group Ⅲ had no history of Ml. All patients received complete UCG and their Tei indexes were examined. Results The Teiindexs were 0.40±0.06, 0.41±0.07, 0.48±0.08 and 0.56±0.15 from group Ⅰ to group Ⅲ respectively. The Tei indexes in group Ⅲ were higher than which of group Ⅰ and group Ⅱ, and the Tel in dexes in the AMI group were significantly higher than which in the other 3 groups. However there was no significant difference between group Ⅰ and group Ⅱ. Conclusion Tei index can reflect the difference of left ventricular cardiac function in patients with different types of coronary artery disease.
