| 摘 要： | 目的:应用多普勒组织成像(DTI)技术检测原发性高血压(EH)不同左心室构型患者三尖瓣环脉冲组织多普勒(PW-DTI)频谱,评价其右心室舒张功能.方法:EH患者80例,按照Ganau分类方法,以左心室质量指数(LVMI)和相对室壁厚度(RWT)分为:正常左心室构型组(EH1组),向心性重构组(EH2组),向心性肥厚组(EH 3组)及离心性肥厚组(EH 4组);另入选20例健康体检者作为正常对照组.取标准心尖四腔切面,用PW-DTI技术测量各组的三尖瓣瓣环舒张早期峰值速度(E),舒张晚期峰值速度(A)及E/A值.结果:与正常对照组比较:EH1、2、3、4组E峰逐渐减低,A峰逐渐增高,E/A比值逐渐减低(P<0.05);EH各组间比较:平均E峰逐渐减低且随左心室构型改变呈下降趋势(P<0.05);平均A峰逐渐增高且随左心室构型改变呈上升趋势(P<0.05).结论:①EH患者早期左心室构型正常时已存在右心室舒张功能减低;②EH患者的右心室舒张功能在不同左心室构型中根据恶化程度呈下降趋势;③DTI技术可用于评价EH患者右心室舒张功能.
