目的:探讨Tei指数评价肥厚型心肌病患者左心功能的临床价值。方法:检测18例肥厚型梗阻性心肌病患者(HOCM组)、15例肥厚型非梗阻性心肌病患者(HNCM组)、20例健康体检者(对照组)左心常规超声指标,记录二尖瓣及主动脉瓣血流频谱,计算Tei指数。结果:与对照组比较,HOCM组与HNCM组E峰减速时间增高,E/A比值降低,Tei值明显增大(P<0.05);HOCM组与HNCM组间差异无统计学意义(P>0.05)。结论:Tei指数能早期、敏感、综合评价HCM患者左心功能变化。
Objective: To investigate the clinical value of Tei index in evaluating left ventricular function in patients with hypertrophic cardiomyopathy. Methods: 18 patients with hypertrophic obstructive cardiomyopathy (HOCM group), 15 hypertensive non-obstructive cardiomyopathy patients (HNCM group) and 20 healthy subjects (control group) Flap and aortic valve blood flow spectrum, calculate Tei index. Results: Compared with the control group, the E peak decelerating time, the E / A ratio and the Tei value increased significantly in HOCM group and HNCM group (P <0.05), but there was no significant difference between HOCM group and HNCM group (P> 0.05 ). Conclusion: The Tei index can be early, sensitive and comprehensive evaluation of left ventricular function in HCM patients.
