目的 :应用组织多普勒成像对冠状动脉 (冠脉 )痉挛引起急性心肌梗塞检测的临床应用价值。方法 :应用组织多普勒成像脉冲技术检测 2 0例冠脉痉挛引起急性心肌梗塞患者左室心尖部和前壁基底段、中段和心尖段的心肌运动 ,测量收缩期、舒张早期和舒张晚期运动峰值速度及时间速度积分并与 19例健康成人对照分析。结果 :冠脉痉挛梗塞组心尖部及前壁中段、心尖段的收缩波、舒张早期波峰值速度及时间速度积分明显低于对照组 ( P<0 .0 1)。舒张晚期波及前壁基底段各测值两组相差不显著 ( P>0 .0 5 )。结论 :组织多普勒成像脉冲技术能够准确测定心肌局部收缩和舒张运动速度 ,对冠脉痉挛引起急性心肌梗塞检测提供一种定量的方法。 Objective: To evaluate the clinical value of tissue Doppler imaging in detection of acute myocardial infarction caused by coronary artery (coronary artery) spasm. Methods: Tissue Doppler imaging pulse technique was used to detect myocardial movement in the basal, middle and apical sections of left ventricular apex and anterior wall in 20 patients with coronary artery spasm. Systolic, early diastolic and late diastolic motion Peak velocity and time velocity integral and 19 healthy adults control analysis. Results: The systolic and early diastolic peak velocities and time velocities in the apical and anterior segments of the infarct group were significantly lower than those in the control group (P <0.01). There was no significant difference between the two groups in late diastole and basement anterior wall (P> 0.05). Conclusion: Tissue Doppler imaging pulse technique can accurately measure the local systolic and diastolic velocity and provide a quantitative method for the detection of acute myocardial infarction caused by coronary spasm.
