摘要
目的探讨Tei指数评价原发性高血压左室功能的临床价值。方法原发性高血压74例,根据WHO将高血压分为3期,Ⅰ期(A组,38例)、Ⅱ期(B组,筛选左室肥厚22例)、Ⅲ期(C组,筛选左心衰14例);对照组(D组,32例)。以常规超声测量舒张末期室间隔(IVS)、左室后壁厚度(LVPW)与左室内径(LVEDD),舒张期二尖瓣口正向血流峰值比(E/A)与右肺上静脉血流峰值S/D比值,左室射血分数(EF)以及Tei指数。结果A、B组E/A均<1(P<0.05);A、B、C组与D组比较S/D增大(P<0.05);高血压各组Tei指数比对照组呈递增性增高(P<0.001)。结论Tei指数能简便、敏感、综合评价高血压左室功能。
Objective To investigate the value of a new index - Tei index for estimating left ventricular global function of essential hypertension. Methods This study included 74 patients with essential （hypentension divided into three groups according to the classifications issued） by the WHO for the hypertension evaluation in which hypertension was classified in 3 stages. Group A consisted of 38 cases matching stage 1. Group B consisted of 22 cases, complicated heart hypertrophy. Group 3 had 14 stage 3 （severe） cases, with complication of left heart failure. There were 32 normal subjects in - group D, which acted as the control group.The conventional echo - Doppler parameters assessed includ- edtheIVS, LVPW, LVEDD, F/A ratio, S/Drafio, ejecfionfraetion（EF）andTeiindex. Results E/A rafio in groups A and B was all less than 1 （ P 〈 0.05） ;The S/D ratio increased compared with group D （ P 〈 0.05） ;The Tei index in groups A, B and C was all greater than the control group （group D） and progressively increased（ P 〈0.001）. Conclusion The Tei index would be valuable and simple for estimating the left ventrieular systolic and diastolic functions with high sensitivity in hypertension patients.
