摘　　要：目的应用超声三维斑点追踪技术(3DSTE)评价左室射血分数正常的原发性高血压(EH)患者左心室旋转及扭转,探讨其早期改变及临床应用价值。方法左心室正常构型的EH患者30例,年龄匹配的正常对照组30例,经胸采集心尖四腔心切面的左室全容积三维动态图像存储,应用随机携带的3DT分析软件进行脱机分析,测量左心室基底段、中间段、心尖段的旋转角度峰值(Prot-base,Prot-mid,Protl-ap),左心室扭转角度峰值(Ptw)。结果EH患者与正常对照组的左室旋转和扭转曲线的形态和走形趋势基本一致。与正常组比较,高血压组的Prot-ap、Prot mid、Ptw明显增加(P均<0.05)。Prot base两组间差异无统计学意义。结论 3DSTE可有效评估EH患者左室旋转及扭转运动,为临床提供了检测高血压患者早期心功能改变的新方法。Objective To assess the clinical value and early changes of left ventricular rotation and twist in essen- tial hypertension （EH） patients with normal left ventricular ejection fraction（LVEF） using 3 dimension speckle track ing echocardiography （3DSTE）. Methods 30 EH patients with left ventricular normal geometry （LVN） and 30 healthy control subjects were included. Real-time 3 dimensional full volume data sets were acquired from apical four chamber views. Peak rotation on basal plane （Prot-base）, peak rotation on middle plane （Prot-mid）, peak rotation on apical plane （Prot-ap） and peak twist angle （Ptw） were measured. Results In the patients with essential hyperten- tion,the trend of the rotation and twist curves remained unchanged, the value of Prot-ap, Prot-mid and Ptw signifi- cantly increased （all P〈0.05） in EH patients, There was no significant difference in Prot base （P〉0.05）. Conclu- sions 3DSTE can effectively assess the left ventrieular rotation and twist in patients with essential hypertension,and 3DSTE is an new tool to evaluate the early change of left ventricular function.
