【摘要】 目的:探讨小剂量多巴酚丁胺负荷试验,检测急性心肌梗塞心肌存活的可靠性和安全性。方法:对20例急性心肌梗塞后2周患者,行检测并于2个月后复查超声心动图,比较分析其室壁节段性运动异常的改变,以判断心肌的存活性。结果:LDDSE预测的存活心肌于2月后复查超声心动图,前后检出存活节段百分比分别为54%和50.8%。结论:LDDSE对AM I早期可较准确预测缺血心肌功能的恢复部位,安全性好。更多还原

【Abstract】 Objective: This study was performed to observe the reliability and safety of Low-dose Doutamine Stress Echocardiography(DSE)in the detection of the viability of myocardium in early acute myocardial infarction.Method: 20 cases of acute myocardial infarction(AMI) were studied with Low-dose DSE before and after coronary angioplasty.The changes of segmental movement in order to assess the viability of myocardium.Results: The viable myocardium by the LDDSE’s predicting was reexamined UCG after two months,the rate of the viable segment is 54% and 50.8% separately.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
