摘要/Abstract

摘要： 目的应用三维斑点追踪成像(3D-STI)技术评价睡眠呼吸暂停综合征患者左、右心室整体收缩功能。方法 OSAS患者60例,根据睡眠呼吸暂停低通气指数(AHI)分为3组,轻度组,中度组,重度组,每组20人;另选择20名健康正常人作为正常对照组。用三维斑点追踪成像技术测量各组左心室整体纵向应变(LVGLS)、圆周应变(LVGCS)、径向应变(LVGRS)、面积应变(LVGAS)以及右心室整体纵向应变(RVGLS)、圆周应变(RVGCS)、径向应变(RVGRS),并比较各组间参数的差异。结果与轻度OSAS组比较,中、重度OSAS组LVGLS、LVGAS降低,差异有统计学意义(P<0.05);与中度OSAS组相比较,重度组LVGLS、LVGCS、LVGRS以及LVGAS均降低,差异有统计学意义(P<0.05);右心室部分应变参数变化早于左心室。结论应用3D-STI技术能够在患者左心室射血分数(LVEF)发生改变之前发现早期左、右心室功能收缩障碍,为临床早期诊断及干预提供可靠的依据。

Abstract: Objective To evaluate left and right ventricular systolic function of patients with obstructive sleep apnea syndrome (OSAS) by using three-dimensional speckle tracking imaging(3D-STI). Methods Sixty patients with OSAS were divided into three groups according to the sleep apnea hypopnea index (AHI), the mild group, the moderate group and the severe group, with 20 patients in each group. Another 20 healthy people were selected as the normal control group. The left ventricle global longitudinal strain (LVGLS), left ventricle global circumferential strain (LVGCS), left ventricle global radial strain (LVGRS), left ventricle global area strain (LVGAS) and right ventricle global longitudinal strain (RVGLS), right ventricle global circumferential strain (RVGCS) and right ventricle global radial strain (RVGRS) were measured by three-dimensional speckle tracking imaging technology, and the differences of parameters between groups were compared. Results Compared with mild OSAS group, LVGLS and LVGAS were decreased in moderate and severe OSAS groups, and the difference was statistically significant (P<0.05). Compared with the moderate OSAS group, LVGLS, LVGCS, LVGRS and LVGAS in the severe group all decreased, and the difference was statistically significant (P<0.05). Some of right ventricle strain parameters were earlier than that of left ventricle. Conclusion The application of 3D-STI technology can detect early left and right ventricular dysfunction before left ventricular ejection fraction(LVEF)changes, provide a reliable basis for early clinical diagnosis and intervention.
