| 摘 要： | 目的:探讨应变率成像(SRI)评价高血压患者左房功能的临床价值。方法:原发性高血压病患者89例,分为左室正常构型组(LVN)40例和左室重构组(LVR)49例;正常人41例为对照组。于心尖四腔切面,应用SRI获取左房侧壁中段应变率曲线,分别测量左室收缩期、舒张早期、舒张晚期左房峰值应变率(SRs、SRe、SRa);应用组织多普勒成像(TDI)获得二尖瓣环附着处左室舒张早期及舒张晚期峰值速率(Ea、Aa),计算Ea/Aa。应用脉冲多普勒(PW)测量二尖瓣E峰及A峰流速(E、A),计算E/A;应用二维超声测量左房前后径(LAD)。结果:与对照组比较,高血压各组SRe及SRs均减低,LVN组SRa增高(P<0.01);高血压各组Ea/Aa均减低,LVR组E/A减低(P<0.01);高血压各组LAD均增高,且LVR组大于LVN组(P<0.01)。结论:SRa、SRe、SRs能够评价高血压病患者左房收缩及舒张功能。

| Abstract: | Objective: To evaluate the clinical value of left atrial function by strian rate imaging (SRI) in primary hypertensive patients. Methods: Eighty-nine patients with primary hypertensions were divided into two groups, normal geometry group (LVN, n=40) and remodeling geometry group (LVR, n=49). Forty-one healthy participants were included as the control. At four-chamber view, the strain rate curves were gained by SRI in the middle segments of each left atrial lateral wall . Strain rate parameters SRs, SRe and ... |
