目的探讨Tei指数评价急性心肌梗死患者心功能的临床价值。方法2004年1月至2005年1月福建省泉州市第一医院心内科95例急性心肌梗死患者,根据左室射血分数(EF)分为EF正常组52例(A组)和EF低下组43例(B组)。另设正常对照组50例(C组)。超声测量左室舒张末期内径(LVDd)和收缩末期内径(LVDs),二尖瓣口舒张早期和舒张晚期血流峰值之比(E/A)、E峰减速时间(EDT)、左室等容舒张时间(IRT)、肺静脉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均较C组增大,EF值均较C组下降,IRT均较C组延长;B组的EDT较C组缩短;A组的S/D较C组增大;A组和B组的Tei指数均较C组延长,B组延长的幅度比A组大;而且差异均具有显著性。结论Tei指数能简便、敏感地综合评价急性心肌梗死患者整体收缩和舒张功能。
Objective To investigate the clinical value of Tei index in evaluating cardiac function in patients with acute myocardial infarction. Methods From January 2004 to January 2005, 95 patients with acute myocardial infarction in Department of Cardiology, First Hospital of Quanzhou, Fujian Province were divided into two groups according to the left ventricular ejection fraction (EF): EF group (52 cases), EF group 43 cases (group B). Another set of normal control group of 50 patients (C group). The left ventricular end-diastolic diameter (LVDd) and end-systolic diameter (LVDs) were measured by echocardiography. The ratio of peak early diastolic and diastolic velocities (E / A), peak decelerating time Diastolic time (IRT), pulmonary venous contractile and diastolic wave ratio (S / D), and Tei index. Results The LVDd and LVDs in group A and group B were both higher than those in group C, while EF values were lower than those in group C and IRT were longer than those in group C. EDT in group B was shorter than group C; S / D in group A was significantly higher than group C Increase; Tei index of group A and group B are longer than group C, group B is longer than group A; And the difference is significant. Conclusion Tei index can be a simple, sensitive and comprehensive evaluation of patients with acute myocardial infarction overall contraction and diastolic function.
