【摘要】 目的 :探讨小剂量多巴酚丁胺负荷超声心动图 (LDDSE)检测急性心肌梗塞 (AMI)心肌存活的可靠性和安全性。材料和方法 :对 2 5例AMI后两周患者 ,在接受冠状动脉成形术治疗前后应用LDDSE检测 ,比较分析其室壁节段性运动异常的改变 ,以判断心肌存活性。结果 :在冠状动脉血运重建术前对室壁节段收缩功能的恢复预测准确率为 80 .2 % ,检测中并发症发生率极低 ( 4 % )。结论 :LDDSE对AMI早期可以较准确预测术后缺血心肌功能的恢复部位 ,安全性好。更多还原

【Abstract】 Purpose: This study was performed to observe the reliability and safety of low dose Dobutamine Stress Echocardiagraphy(DSE) in the detection of the viability of myocardium in early acute myocardial infarction. Materials and Methods: Twenty five cases of acute myocardial infarction(AMI) were studied with low dose DSE before and after coronary angioplasty. The changes of segmental movement of ventrical wall were analyzed in order to assess the viability of myocardium. Results: The accuracy of prediction of the recovery of segmental movement of ventrical wall before the reconstruction of coronary blood flow was 80.2% and few complication of low dose DSE was encountered. Conclusion: Low dose DSE was a sate technique with high precision in predicting the recovery of segmental movement of ventrical wall after AMI.更多还原
