摘要
目的:应用速度向量成像(VVI)技术评价高血压患者左室扭转运动。方法:对20例健康成人和58例原发性高血压患者行常规二维超声心动图检查后,根据左室壁厚度及二尖瓣口血流E/A值,将原发性高血压患者分为3组:单纯高血压组(20例)、高血压伴左室舒张功能下降组(20例)、高血压伴左室肥厚组(18例)。进行采集并存贮3beats状态下心底部短轴切面和心尖部短轴切面二维超声动态图,在VVI模式下对受检者勾画心内膜,应用VVI软件自动跟踪分析左室扭转角度。结果:与正常组比较,高血压各组扭转角度明显增大,差异均有统计学意义(P<0.01),高血压各组间比较左室扭转角度差异均有统计学意义(P<0.01)。结论:VVI技术能够简便、无创的评价心脏扭转运动,对高血压引起心脏损害的诊断提供一种有价值的检查手段。
Objective： Apphcatton of w, y o with left ventricular twisting motion, Methods： 20 normal adults and 60 patients with Primary hypertension were Undergone a medical examination by conventional two - dimensional echocardiography, according to the disease progresses, patients with Primary hypertension were divided into three groups： hypertension group （20 cases）, hypertension with left ventricular diastolic dysfunction group （20 cases）, hypertension with left ventricular hy- dy- 1 pertrophy （18 cases）. Under the 3beats condition gatneru g and storeing the two dimensional supersonic namic chart of heart base minor axis section and the heart point minor axis section, the endocardium o[ the pa- tient were outlined under VV｜ pattern, appling VVI software automatic tracking to analyzed the left room re- verse angle. Resuls：Compari~）n of Ve and SRe compared with the control group, A group only basal septal, an- terior wall and lateral wall of the central early diastolic peak velocity （Ve） decreased, the difference was statisti- cally significant（ P〈0.05, P 〈 0.01）, the remaining segment of Ve had no significant difference; The most segment of group B （posterior wall of the middle,the inferior wall and apical ventricular seplal except） Ve were significantly lower （ P 〈0.01） ; All segments of C group, Ve were significant lower than the control group（P 〈0.01 ） ;Among three groups of hypertensive patients Ve decreased, the difference between the groups（except for posterior wall of the middle,inferior wall and apical ventricular septal extracellular of the A group and B group） were statistically significant（P 〈 0.05, P〈0.01）. Most segments of group A （except of basal lateral wall, the central anterior septal） early diastolic decreasing SRe than those in the control group, the difference was statisti- cally significant （ P 〈 0.05, P 〈 0.01 ） ： B group segments （except of central anterior septal） SRe were significant lower than the control group （P 〈 0.01）; C group all segments SRe were significant lower than the control group（P 〈 0.01）; three groups among patients with hypertension, among all groups （except of A group and B group central anterior septal） the difference was statistically significant（P 〈 0.05, P 〈 0.01）. Conclusion： VVI technology is simple, non- wounded evaluation of cardiac reverse the movement, diagnosis of hypertension- induced cardiac damage provides a valuable means of checking.
