| 摘要 目的：评价超声二维斑点追踪显像技术（2D-STI）对冠心病（CAD）患者左心房、左心室功能的临床应用价值。方法：选取2015年12月至2016年12月因CAD在我院住院就诊患者30例作为实验组，另选取同期健康体检者30例为对照组，采用彩色多普勒超声仪应用2D-STI测量左心室各节段心内膜下心肌、中层心肌、心外膜下心肌纵向应变（TLSendo，TLSmid，TLSepi），左室心内膜下心肌、中层心肌、心外膜下心肌整体纵向应变（GLSendo，GLSmid，GLSepi），左心室收缩期左心房应变率（SRs），左心室舒张早期左心房峰值应变率（SRe）和左心室舒张晚期左心房应变率（SRa），并计算其平均值（mSRs,mSRe,mSRa）。比较两组之间的数据。结果：实验组TLSendo为（21.45±9.02）% ，TLSepi为（15.22±5.12）%，低于对照组的（26.55±7.59）%、（18.79±3.77）%，差异有统计学意义（P＜0.05）。实验组GLSendo为（21.07±3.12）%，GLSmid为（18.11±2.57）%，GLSepi为（15.79±3.11）%，均低于对照组的（23.55±2.59）%、（20.82±2.04）%、（18.07±2.00）%，差异有统计学意义（P＜0.05）。实验组mSRs和mSRe分别为（3.41±0.68）、（-3.09±0.82），低于对照组的（4.55±0.69）、（-3.67±1.30）；实验组mSRa为（-4.47±1.33），高于对照组的（-3.52±1.44），差异均有统计学意义（P＜0.05）。同一检查者两次测量结果的相关系数为r=0.935，P＜0.05；不同检查者的测量结果相关系数为r=0.931，P＜0.05。结论：2D-STI可以定量评价CAD的左心功能，其表现主要为左室各层心肌收缩功能降低，左心房储备功能降低。 |

| ABSTRACT Objective: To assess the clinical value of two-dimensional specking-tracking imaging (2D-STI) in the diagnosis of left atrial and left ventricular function in patients with coronary atherosclerotic disease（CAD）. Methods: A total of 30 patients with CAD, who were admitted to Armed Police Corps Hospital of Hubei from December 2015 to December 2016, were chosen as experimental group; another 30 healthy subjects were selected as control group. Color Doppler ultrasound 2D-STI was used to measure the longitudinal strain of left ventricular segmental subendocardial myocardium, midmyocardium and subepicardial myocardium (TLSendo; TLSmid; TLSepi), the global longitudinal strain of left ventricular segmental subendocardial myocardium, midmyocardium and subepicardial my- ocardium (GLSendo; GLSmid; GLSepi), left ventricular systolic left atrial strain rate (SRs), left ventricular early diastolic left atrial peak strain rate (SRe) and left ventricular late diastolic left atrial strain rate (SRa), and the mean values were calculated (mSRs; mSRe; mSRa).The data were compared between the two groups. Results: The TLSendo [（21.45±9.02）%] and TLSepi [(15.22±5.12)%] of the experi- mental group were lower than those[(26.55±7.59)% and (18.79±3.77)% ] of the control group, the differences were statistically signifi- cant (P<0.05). The GLSendo[（21.07±3.12）%], GLSmid [(18.11±2.57)%] and GLSepi[（15.79±3.11）%] of the experimental group were lower than those[(23.55±2.59)%, (20.82±2.04)%, and (18.07±2.00)%] of the control group,the differences were statistically sig- nificant (P<0.05). The mSRs(3.41±0.68) and mSRe(-3.09±0.82) of the experimental group were lower than those[(4.55±0.69) and (-3.67±1.30)] of the control group; the mSRa (-4.47±1.33) of the experimental group was higher than that[(-3.52±1.44)] of the control group, the differences were statistically significant (P<0.05). The correlation coefficient between the two measurements of the same ex- aminer was r=0.935(P<0.05), the correlation coefficient of the different examiners measurement results was r=0.931(P<0.05). Conclusion: 2D-STI can be used to quantitatively evaluate left ventricular function in patients with CAD. The main manifestations are the decrease of myocardial contractile function and the reduction of the left atrial reserve function in the left ventricle. |
