摘　　要：目的:探究二维斑点追踪成像技术(2D-STI)在阻塞性睡眠呼吸暂停低通气综合征(obstructive sleep apnea hypopnea syndrome,OSAS)患者左心室功能定量评估中的临床应用。方法:选择2016年7月～2018年12月在我院就诊的86例OSAS患者作为OSAS组,按睡眠呼吸暂停低通气指数(AHI)将其分为轻度OSAS组(24例)、中度OSAS组(29例)和重度OSAS组(33例)。另选择同期在我院进行体检的50例健康志愿者作为对照组。采用2D-STI技术对所有受检者的左心室功能进行定量评估,对OSAS组、对照组患者以及不同严重程度的OSAS患者的常规超声心动图检查结果和左心室整体应变参数进行对比分析。结果:两组受检者以及不同严重程度的OSAS患者的左心室射血分数(LVEF)、左心室舒张末期内径(LVEDd)、左心室收缩末期内径(LVESd)水平比较无显著差异(P>0.05)。OSAS组患者的舒张末期室间隔厚度(IVS)、左心室后壁厚度(LVPW)、左室质量指数(LVMI)水平均明显高于对照组,重度OSAS组患者的IVST、LVPW和LVMI水平明显高于轻度和中度OSAS组,中度OSAS组患者的IVST、LVPW和LVMI水平明显高于轻度OSAS组,组间差异比较有统计学意义(P<0.05)。OSAS组患者的整体纵向应变(GLS)、整体径向应变(GRS)、整体圆周应变(GCS)水平均明显低于对照组,差异比较有统计学意义(P<0.05)。重度OSAS组患者的GLS、GRS和GCS水平明显低于轻度OSAS组和中度OSAS组,中度OSAS组患者的GLS、GRS和GCS水平明显低于轻度OSAS组,差异比较有统计学意义(P<0.05)。结论:OSAS患者的左心室收缩功能明显受损,借助二维斑点追踪成像技术能够及时、准确地对OSAS患者的左心室功能进行评估。Objective: To research the clinical application of two-dimensional speckle tracking imaging (2D-STI) in quantitative assessment of left ventricular function in patients with obstructive sleep apnea-hypopnea syndrome (OSAS). Method: From July 2016 to December 2018, 86 patients with OSAS were selected as OSAS group. According to sleep apnea hypopnea index (AHI), they were divided into mild OSAS group (24 cases), moderate OSAS group (29 cases) and severe OSAS group (33 cases). Another 50 healthy volunteers who underwent physical examination in our hospital during the same period were selected as the control group. The left ventricular function of all patients was quantitatively assessed by 2D-STI. The left ventricular function of all patients was quantitatively assessed by 2D-STI. The results of routine echocardiography and left ventricular global strain parameters of the OSAS group, the control group and the OSAS patients with different severity were compared and analyzed. Result:There were no significant differences in the levels of left ventricular ejection fraction (LVEF), left ventricular end diastolic diameter (LVEDd), left ventricular end systolic diameter (LVESd) between the two groups and OSAS patients with different severity ( P >0.05). The levels of IVST, LVPW and LVMI in the OSAS group were significantly higher than those in the control group, the levels of end-diastolic interventricular septal thickness (IVS), left ventricular posterior wall thickness (LVPW), left ventricular mass index (LVMI) in the severe OSAS group were significantly higher than those in the mild and moderate OSAS group, and the levels of IVST, LVPW and LVMI in the moderate OSAS group were significantly higher than those in the mild OSAS group, there were significant differences between groups ( P <0.05). The levels of GLS, GRS and GCS in the OSAS group were significantly lower than those in the control group ( P <0.05). GLS, GRS and GCS levels in the severe OSAS group were significantly lower than those in the mild OSAS group and th
