There are several potential causes for the occurrence of myocardial ischaemia after successful coronary angioplasty, but the role of ambulatory electrocardiographic monitoring, particularly in the detection of coronary restenosis, remains undefined in these patients. Previous studies have shown that ambulatory monitoring demonstrates ST-segment changes in only a minority of patients before, and rarely after, successful angioplasty. The presence of transient myocardial ischaemia, whether symptomatic or silent, on ambulatory electrocardiographic monitoring has not been shown to relate to the outcome, frequency of complications, or rate of restenosis in patients after successful angioplasty. Ambulatory electrocardiographic monitoring and exercise testing are complementary investigative techniques for the detection of myocardial ischaemia after successfully coronary angioplasty. Their roles will depend on the type of ischaemic syndrome present, its presentation and the pathophysiological mechanisms involved.
成功进行冠状动脉血管成形术后发生心肌缺血有多种潜在原因，但动态心电图监测的作用，尤其是在检测冠状动脉再狭窄方面，在这些患者中仍不明确。先前的研究表明，动态监测仅在少数成功血管成形术之前的患者中显示出ST段改变，而在术后则很少出现。动态心电图监测上短暂性心肌缺血的存在，无论有无症状，均未显示与成功血管成形术后患者的预后、并发症发生率或再狭窄率相关。动态心电图监测和运动试验是检测成功冠状动脉血管成形术后心肌缺血的互补性检查技术。它们的作用将取决于所存在的缺血综合征类型、其表现形式以及所涉及的病理生理机制。
