摘　　要：目的探讨二维斑点追踪成像(STI)技术的心肌扭转与旋转指标对评价急性前壁心肌梗死(AMI)的意义。方法 49例患者PCI术前和术后72 h内行超声心动图检查,进行常规超声参数及STI参数测定。结果常规超声指标仅LVEF值有统计学意义(P<0.05);前壁心尖段术后局部扭转速度与解旋速度较术前提高,扭转时间与解旋减半时间较术前减少,左室基底段和心尖段的整体解旋角度术后均增加(P﹤0.05)。结论 STI技术的左室扭转解旋指标可定量评价心肌梗死患者术后左心整体与节段舒缩功能。Objective To analyze the significance of myocardial torsion and rotation indicators after speckle tracking imaging（STI） in detecting the acute myocardial infarction（AMI）. Methods Forty nine patients were examined by echocardiography at 72h before and after the PCI,the conventional and STI parameters were measured. Results Only the LVEF of conventional ultrasound parameters showed the statistical significance（P0.05）.The local torsion speed and untwist speed after apical segment surgery were increased,the torsion time and half-time rotation were decreased,the whole untwist angle of basal segment and apical segment were increase than those before the surgery（P0.05）. Conclusion Myocardial torsion and rotation indicators after STI could quantitative evaluate the whole and segmental cardiac systolic and diastolic function of left ventricular
