中国循环杂志99zk84 目的：以持续监测ST段评估急性心肌梗塞(AMI)早期梗塞相关动脉(IRA)的动态变化。
方法：对发病≤6小时的61例(男46例、女15例，年龄39～80岁)AMI患者进行动态心电图监测，持续观察24小时ST段变化并与冠状动脉造影结果作对照。
结果：①IRA未开通者ST段持续抬高并伴有逐渐下降趋势；②溶栓疗法和直接经皮冠状动脉腔内成形术治疗成功后ST段迅速下降并保持相对稳定；③所有患者24小时内均见有间断发生的ST段抬高和下降波动性变化，特别多见于溶栓成功早期。
结论：AMI发病早期IRA处于动态的开放-关闭状态，持续监测ST段能较全面反应IRA变化。

Objective: To evaluate the dynamic change of infarct-related arteries (IRA) with continued monitoring of ST segment in early acute myocardial infarction (AMI).
Methods: 61 patients (46 males and 15 females, aged 39～80) with AMI underwent 24 hours, Holter monitoring within 6 hours after the symptom onset. The changes of ST segment was observed continually and was compared with the results of coronary arteries angiography.
Results: ① In the patients who had occluded IRA, ST segment remained elevated with a tendency to decline. ② In those who had successful reperfusion, ST segment reduced rapidly after reperfusion and then kept stable. ③ Intermittent fluctuating up and down of ST segment was observed commonly during the first 24 hours in all AMI patients, especially in the earlier time after successful thrombolysis.
Conclusion: The dynamic changes of IRA between opening and occluding were showed in early AMI. The continued monitoring of ST segment can be used to evaluate the dynamic changes of IRA., http://www.100md.com
