摘　　要：目的应用二维斑点追踪成像通过测量左室纵向峰值旋转角度评价冠状动脉粥样硬化性心脏病(简称冠心病)患者行冠状动脉支架植入(PCI)术前、术后1周、1个月心功能的改变。方法冠心病患者19例为冠心病组,61例体检健康者为对照组。PCI术前和术后1周、1个月,二维斑点追踪成像测量左室各室壁节段及整体纵向峰值旋转角度。结果对照组与冠心病组左室侧壁均呈逆时针旋转,室间隔呈顺时针旋转。与对照组比较,冠心病组室间隔纵向旋转角度及左室整体纵向峰值旋转角度增大,左室侧壁纵向旋转角度减小(均P<0.05)。与PCI术前比较,冠心病组术后1周左室各室壁节段及整体纵向峰值旋转角度差异均无统计学意义;术后1个月基底段室间隔纵向峰值旋转角度和左室整体纵向峰值旋转角度均减小(P<0.05)。结论冠心病患者心脏存在纵向顺时针旋转,PCI术后1个月心功能得到一定恢复,二维斑点追踪成像能反映心功能变化。Objective To assess the cardiac function of patients with coronary heart disease （CHD） before and after percutaneous coronary intervention（PCI） by two-dimensional speckle tracking imaging （2D-STI）. Methods Nineteen patients with CHD and 61 healthy controls were enrolled in this study. The segmental longitudinal rotation （LR） and global LR were assessed by 2D-STI before PCI, one week and one month after PCI. Results The left ventricular lateral wall was rotated antieloekwise, and the septal wall was rotated clockwise in healthy controls and CHD patients. Compared with healthy controls, the LR angle of left ventricular lateral wall was decreased but longitudinal peak rotation angle of left global ventricular was increased in CHD patients （P〈0.05）. No differences were found in the segmental LR and global LR one week after PCI. One month after PCI, the peak LR of all the LV walls were decreased （P〈0.05）. Conclusion Clockwise LR is found in CHD patients and the eardiae function can be improved one month after PCI. 2D-STI can assess the change of cardiac function in CHD patients.
