Tei指数对青年原发性高血压患者左心功能的评价

目的探讨Tei指数检测青年原发性高血压患者心功能变化的临床应用价值。方法采用脉冲多普勒及组织多普勒显像技术对30例正常对照组、40例青年原发性高血压患者进行左心室Tei指数测定，用二维Simpson法测定左室射血分数（EF），用脉冲多普勒测定二尖瓣血流频谱E峰与A峰的比值（E／A）。结果高血压组左室Tei指数显著高于正常对照（P〈0．05）；左室EF、E／A高血压组与正常对照组比较差异无统计学意义（P〉0．05）。结论青年高血压患者早期即存在心功能改变；Tel指数能准确定量评价青年高血压患者整体心功能变化。

Assessment of the Changes of Left Ventricular Function in Young Patient with Essential Hypertension Using Doppler Tel Index

Objective To assess the clinical value of inspecting the changes of ventricular function in young patient with essential hypertension by applying Doppler Tei index. Methods Determined the left ventricular Tei index by applying pulse doppler and doppler imaging technique, determined left ventrieular by applying two dimensional Simpson, determining atrioventricular valve ratio of E/A of the 30 normal subjects and 40 young patient with essential ypertension. Results The left ventricular Tel index in youth essential hypertension patients was obviously higher than in the normal subjects （ P 〈 0.05 ）, but there is no statistic significance in the difference between left ventrieular EF and E/A and normal subjects （P 〉 0.05 ）. Coneluslon Young patients with essential hypertension have left ventrieular function change in the early stage, the Tel index can accurately assess the overall change of ventrieular function in young patient with essential hypertension quantitatively.
