摘要
目的：探讨应用实时三维超声心动图（RT-3DE）评价高血压病患者左心室重构的价值。方法：采集96例高血压病患者（32例正常构型组，28例向心性肥厚组，36例离心性肥厚组）与36例正常人的左心室三维图像。测量左室舒张末期容积（LVEDV）、左室舒张末期心外膜容积（EDVepi）、左室重构指数（LVRI），结果与二维超声心动图（2DE）Simpson法测值比较。结果：①RT-3DE与2DE检测的LVRI、EDVI、LVMI值在各组间差异均有统计学意义（P<0.05），对照组内、高血压病正常构型组内、高血压病向心性肥厚组内差异无统计学意义（P>0.05），而在高血压病离心性肥厚组内差异有统计学意义（P<0.05）；②对照组、高血压病正常构型组、高血压病向心性肥厚组内，RT-3DE和2DE检测的LVRI、EDVI、LVMI值均呈显著正相关。高血压病离心性肥厚组内RT-3DE与2DE检测的LVRI、EDVI、LVMI值均不显著相关。结论：运用RT-3DE评价高血压病患者左心室重构和左室壁运动同步性具有形态和功能相结合的优点，是有效、准确的无创性检查方法，对高血压病患者病情的发展和预后判断具有重要的临床意义。
Abstract
Objective: Using real-time three-dimensional echocardiography(RT-3DE) to assess left ventricular remodeling in patients with hypertensive heart disease(HHD). Methods: RT-3DE data of 96 HHD(32 normal configuration, 28 concentric hypertrophy, 36 eccentric hypertrophy), 36 normal controls were acquired. Left ventricular end-diastolic volume(LVEDV), left ventricular end-diastolic epicardial volume(EDVepi) by RT-3DE and two-dimensional echocardiography(2DE) Simpson biplane method; left ventricular mass(LVM), left ventricular mass index(LVMI), left ventricular end diastolic epicardial volume index(EDVI), left ventricular remodeling index(LVRI) were calculated and compared. Result: ①LVRI, EDVI, LVMI measured by RT-3DE and 2DE were significantly different inter group, in eccentric hypertrophy groups(P<0.05), but no significantly different in normal control group, normal configuration and concentric hypertrophy(P>0.05); ②The LVRI, EDVI, LVMI had significant correlation between RT-3DE, 2DE in normal control group, normal configuration and concentric hypertrophy, the LVRI, EDVI, LVMI had no significant correlation between RT-3DE, 2DE in eccentric hypertrophy. Conclusions: RT-3DE LVRI can be a new approach for evaluating left ventricular remodeling and systolic synchronicity in clinic.
