【摘要】：目的应用三维斑点追踪(3D-STI)技术评价阻塞型睡眠呼吸暂停低通气综合征(OSAHS)伴高血压(HT)患者左心室整体收缩功能。方法 OSAHS 40例,分为单纯OSAHS组20例和OSAHS+HT组20例;另选择20名健康正常人作为正常对照组。行常规超声心动图检查,采集左心室心尖四腔三维全容积图像,存储图像并应用3D-STI分析软件在线分析,计算左心室整体纵向收缩峰值应变(GLS)、左心室整体径向收缩峰值应变(GRS)、左心室整体圆周收缩峰值应变(GCS)及左心室整体面积收缩峰值应变(GAS)。结果与正常对照组相比,OSAHS组左心室GLS、GRS、GAS减低(P均0.05),OSAHS+HT组左心室GLS、GRS、GCS、GAS均减低(P均0.05)。与OSAHS组比较,OSAHS+HT组左心室GLS、GCS、GAS均减低(P均0.05)。结论 OSAHS合并HT患者存在左心室收缩功能受损。3D-STI能早期、准确有效地评估其左心室整体收缩功能改变。OSAHS患者心脏结构及功能变化独立于HT而单独存在,二者同时存在时改变加重。
[Abstract]:Objective to evaluate the left ventricular global systolic function in patients with obstructive sleep apnea hypopnea syndrome (OSAHS) with hypertension (HT) by three dimensional dot tracing (3D-STI). Methods 40 cases of OSAHS were divided into OSAHS group (n = 20) and OSAHS HT group (n = 20). Three dimensional full volume images of left ventricular apical four lumen were collected by routine echocardiography. The images were stored and analyzed on line by 3D-STI analysis software. The (GLS), of left ventricular longitudinal peak systolic strain was calculated. Left ventricular global radial systolic peak strain (GRS), left ventricular global circumferential systolic peak strain (GCS) and left ventricular global area systolic peak strain (GAS). Results compared with the normal control group, the left ventricular GLS,GRS,GAS in the OSAHS group was lower than that in the control group (P0.05). The left ventricular GLS,GRS,GCS,GAS in the), OSAHS HT group was significantly lower than that in the control group (P0.05). The left ventricular GLS,GCS,GAS in, OSAHS HT group was lower than that in OSAHS group (P0.05). Conclusion left ventricular systolic function is impaired in patients with OSAHS combined with HT. 3D-STI can evaluate the changes of left ventricular global systolic function in early stage and accurately and effectively. The changes of cardiac structure and function in patients with OSAHS are independent of HT, but exist alone in patients with OSAHS. When both of them exist at the same time, the change aggravates.
