摘要 目的:使用二维双平面Simpson法评价高血压病患者左心房(LA)容积及功能。方法:选取20例高血压病患者,除外房颤、瓣膜病、肥厚型心肌病、肺心病、心肌梗死或超声心动图上存在明显节段运动异常等器质性心脏病。采用彩色多普勒超声心动图仪于心尖四腔心切面及心尖二腔切面采集LA二维图像,下线描记双平面LA面积,测量左房各期容积。结果:两组间性别、年龄、体表面积、合并疾病及LAD、LVEDD、LVEF等常规超声心动图指标均无统计学差异;高血压病组IVS、LVPW及RWT明显高于对照组;两组间E/E’无明显差异,高血压病组DT较对照组呈延长趋势,A、A’较对照组呈增高趋势,E’呈降低趋势;高血压病组E、E/A明显低于对照组;两组间LAVmin、LAEFtotal无显著差异,高血压病组LAEFpas较对照组呈降低趋势,LAVmax、LAVPreP较对照组呈增大趋势,LAEFact明显高于对照组。结论:与LA内径相比较,二维双平面Simpson法-LAV更加精确,更接近于LA真实容积,更好地反映了舒张功能的异常,并可以很好地预测AF的发生。二维双平面Simpson法评价高血压病患者左心房容积及功能对其长期预后有重要意义并能较好满足临床需求。
