目的:探讨Tei指数评价Ⅰ级高血压病患者左心室功能的临床价值。方法:选择高血压病患者107例,其中左心房径线正常35例(A组)、左心房增大72例(B组),同期健康体检30例为对照组。常规行超声心动图检查,测量左心房内径、室间隔厚度、左心室舒张末期内径及左心室收缩末期内径,二尖瓣口血流频谱舒张早期和舒张晚期血流峰值之比(E/A),左心室射血分数及Tei指数。结果:B组左心房内径较A组和对照组增大(P<0.05);E/A值较A组、对照组减小(P<0.05),A组E/A值与对照组比较差异无统计学意义(P>0.05);A,B组Tei指数较对照组增高(P<0.05),且B组Tei指数与A组比较差异有统计学意义(P<0.05)。结论:Tei指数可敏感反映早期高血压病患者左心房结构尚未改变时左心功能下降情况。
Objective: To investigate the clinical value of Tei index in evaluating left ventricular function in patients with grade I hypertension. Methods: A total of 107 patients with hypertension were selected. Among them, 35 patients with normal left atrial diameter (group A) and 72 patients with left atrial enlargement (group B), and 30 patients with normal physical examination as control group. Routine echocardiography, left atrial diameter, interventricular septum thickness, left ventricular end-diastolic diameter and left ventricular end-systolic diameter, mitral inflow velocity spectrum early diastolic and diastolic blood flow peak ratio (E / A) , Left ventricular ejection fraction and Tei index. Results: The diameter of left atrium in group B was higher than that in group A and control group (P <0.05); the E / A value was lower than that in group A and control group (P <0.05) The Tei index in group A and group B was higher than that in control group (P <0.05), and the Tei index in group B was significantly different from that in group A (P <0.05). Conclusion: The Tei index can reflect the decline of left ventricular function in patients with early-stage hypertension with left atrial structure unchanged.
