| 目的 应用实时三维超声心动图技术评价高血压病患者心室质量、容积和功能改变。方法 在38例正常人、36例高血压无左室肥厚(NLVH)患者和31例高血压伴左室肥厚(LVH)患者中进行了超声心动图检查。应用二维超声双平面Simpson法测量左室舒张末期容积(EDV)、收缩末期容积(ESV)和射血分数(EF),实时三维超声测量左室质量(LVM)及左室质量指数(LVMI), 左、右心室容积、左房最大容积(Vmax)、最小容积(Vmin)及Vmin/Vmax。结果 应用实时三维超声心动图16平面、8平面法、4平面法与2平面法、二维超声双平面Simpson法测量的左室EDV、ESV、EF各组测值之间差异有统计学意义。应用RT-3DE 16平面法测量的LVM、LVMI低于M型超声测值。与对照组比较,高血压NLVH组、LVH组三维超声测量的左室EDV、ESV均显著增高,高血压LVH组左室EF减低;高血压LVH组、NLVH组右室EDV、ESV均较对照组增大,两组左房Vmax、Vmin增加,LVH组Vmax/Vmax增加。结论 实时三维超声技术能够定量评价高血压病患者左、右心室及左房容积和功能,测量左心室质量。 |

| Objective Using real-time three-dimensional echocardiography (RT-3DE) to assess biventricular volumes, function and mass in patients with hypertension. Methods Biventricular and left atrial volumes, ejection fraction and left ventricular mass were determined by RT-3DE in 38 normal controls and 67 patients with hypertension which was divided into left ventricular hypertrophy (LVH) group and non-left ventricular hypertrophy (NLVH) group. Results The end-diastolic volume (EDV), end-systolic volume (ESV) of the left ventricle by RT-3DE 16-, 8-and 4-plane were greater than those obtained with RT-3DE 2-plane and two-dimensional echo (2DE), while ejection fraction(EF) was smaller (P＜0.05). Compared with control group, EDV and ESV of left-and right-ventricular and left ventricular mass increased in LVH group and NLVH group(P＜0.05). EF of left ventricle decreased in LVH group(P＜0.05). LAVmax and LAVmin also increased in LVH group and NLVH group than those of controls, LAVmin/LAVmax only in LVH group(P＜0.05). Conclusion The application of real-time three-dimensional echocardiography presents an important tool for the quantification of cardiac performance and left ventricular mass in the patients with hypertension. |
