摘要：

目的 :探讨 Tei指数评价冠心病患者心功能的临床价值。方法 :冠状动脉造影检查显示左冠状动脉主干或其主要分支至少 1支狭窄≥ 70 %的患者 45例 ,根据左室射血分数 (EF)分为 EF正常组 (EF≥ 50 % ,2 6例 ,A组 ) ,EF低下组 (EF<50 % ,1 9例 ,B组 )。正常对照组 2 7例 (C组 )。行常规超声心动图检查测量左室舒张末期内径和收缩末期内径 (LVDd,LVDs) ,二尖瓣口血流图舒张早期和舒张晚期血流峰值之比 (E/A)、 E峰减速时间 (DT)、左室等容舒张时间 (IVRT)、肺静脉血流图收缩波和舒张波之比 (S/D)以及 Tei指数。结果 :A组和 B组的 LVDd和 LVDs较 C组增大 [(50 .2 7± 4.56) mm,(60 .0 0± 5.1 9) mm和 (46.67± 2 .59) mm;(33.62± 4.74) mm,(44.89± 6.1 1 ) mm和 (2 9.1 1± 1 .69) mm,P值均 <0 .0 1 ] ,IVRT较 C组延长 [(1 2 3.2 1± 1 5.0 0 ) ms,(1 1 9.47± 1 9.74) ms和 (1 0 3.0 9± 1 1 .82 ) ms,P值均 <0 .0 1 ] ;B组的 DT较 C组缩短 [(1 4 4 .74± 33.2 6) ms和 (1 78.0 6± 2 2 .46) ms,P值均 <0 .0 1 ] ;A组的 S/D较 C组增大 (1 .41± 0 .1 5和 1 .2 7± 0 .2 0 ,P<0 .0 5) ;A组和 B组的 Tei指数均较 C组延长 (0 .71± 0 .1 2 ,0 .87± 0 .2 4和 0 .46± 0 .0 9,P值均 <0 .0 1 ) ,而且B组延长的
