摘　　要：目的:应用速度向量成像(VVI)技术评价尿毒症高血压患者节段性心肌收缩功能的变化。方法:利用VVI技术检测25例尿毒症高血压患者左室心尖长轴切面左室壁基底段、中间段和心尖段收缩期峰值速度(Vs)、收缩期峰值应变(ε),另取25例健康志愿者进行对照。结果:尿毒症高血压患者心肌各节段Vs、ε较对照组显著降低(P<0.05),并且失去正常节段的运动规律。结论:VVI技术可敏感评价尿毒症高血压患者局部心肌受损情况。Objective To investigate the change of left ventricular（LV） regional myocardial systolic function by velocity vector imaging（VVI） in patients with uremia hypertension.Methods The systolic peak velocity（Vs） and peak systolic strain（ε）of basal,mid and apical segments along LV apical long axis view were determined by VVI in 25 patients with uremia hypertension and then compared with 25 cases of healthy controls.Results The Vs and ε of all segments were significantly decreased in patients with uremia hypertension compared with those of control group（P0.05）.Conclusion VVI is a sensitive technology in evaluating myocardial regional systolic dysfunction of uremia hypertension.
