| 摘 要： | 背景二尖瓣环运动速度可用于评价左室整体收缩、舒张功能,原发性高血压患者舒张功能障碍已为人们熟知,反映左室收缩功能的指标二尖瓣环收缩期速度也可能有变化。目的探讨应用组织速度显像(TVI)探讨原发性高血压患者二尖瓣环收缩期运动速度的变化特征。方法依照左室质量指数(LVMI)将高血压组患者(n=139)分为左室肥厚组(LVH 组,n=61),与非左室肥厚组(N-LVH 组,n=78)。对高血压组及正常对照组(对照组,n=76)利用 TVI 测量心尖四腔、心尖两腔、心尖长轴切面二尖瓣环六位点收缩期峰速度均值(M-Sa)、舒张期早期运动速度(M-Ea)、舒张期晚期运动速度(M-Aa)、计算 Ea/Aa,以及 E/Ea。比较3组间心功能指标的差异及各参数间的相关关系。结果 M-Sa 在正常对照组、N-LVH 组、LVH 组进行性降低(6.6±1.1)、(5.9±1.2)、(5.2±1.5)cm/s,N-LVH 组、LVH 组 M-Sa、M-Ea、M-Ea/M-Aa 低于对照组(P<0.01),LVH 组又低于N-LVH 组(P<0.05)。M-Sa 与 LVMI(r=-0.363,P<0.01)呈负相关。M-Sa 与 M...

| Abstract: | Background The mitral annular peak velocities has been used to evaluate left ventricular globle and diastolic function in patients with essential hypertension.However,there is a paucity of reports about its value in detecting LV systolic function.Objective To evaluate left ventricular systolic function in patients with essential hypertension by tissue velocity imaging (TVI).Methods One hundred and thirty nine patients with essential hypertension were classified as LVH group(n=61) and N-LVH group(n= 78) base... |
