The study was designed to compare the Doppler myocardial performance index (Tei index) between those patients with systemic hypertension with normal populations. 50 patients with hypertension (16 with left ventricular hypertrophy and 34 without hypertrophy) were taken as cases and 52 age & sex matched healthy individuals were taken as controls. Left ventricular global function was calculated using the echocardiographic Doppler index as described by Tei et al. (Tei index). Left ventricular global function differs significantly between the groups. It does not differ significantly between those with left ventricular hypertrophy and without hypertrophy. Pulmonary venous flow parameters revealed significant increase in atrial reversal velocity and also significant lengthening of atrial reversal duration. All of these parameters signify worsening diastolic properties. The Tei index is not affected by increasing age and therefore, is appropriate for evaluating left ventricular global function in hypertensive patients, most of whom are middle aged or older. This index may be useful for determining treatment strategy and evaluating treatment effects.
本研究旨在比较系统性高血压患者与正常人群之间的多普勒心肌性能指数（Tei指数）。选取50例高血压患者（16例有左心室肥厚，34例无肥厚）作为病例组，52例年龄和性别匹配的健康个体作为对照组。采用Tei等人描述的超声心动图多普勒指数（Tei指数）计算左心室整体功能。两组之间左心室整体功能存在显著差异。有左心室肥厚和无肥厚的患者之间差异不显著。肺静脉血流参数显示心房逆向血流速度显著增加，心房逆向血流持续时间也显著延长。所有这些参数均表明舒张功能恶化。Tei指数不受年龄增长的影响，因此适用于评估大多数为中年或老年的高血压患者的左心室整体功能。该指数可能有助于确定治疗策略和评估治疗效果。
