急性ST段抬高心肌梗死患者经皮冠状动脉介入治疗术后再溶栓治疗

目的探讨急性ST段抬高心肌梗死（STEMI）患者经皮冠状动脉介入治疗（PCI）术后再溶栓治疗可行性机理。方法根据急性STEMI绝大多数病理特征是由于不稳定的粥样斑块破溃，继而出血和管腔内血栓形成，使管腔闭塞这一机理，围绕PCI术后血栓的何去何从展开逐层分析论证。结果急性STEMI患者不可能在破损处经PCI术后完全恢复原位，或多或少伴有小的斑块脱落，这除与导丝的机械操作相关外，斑块自身的不稳定因素易致破裂。结论急性STEMI患者PCI术后若无禁忌证再予溶栓理论操作可行。

To discussion the hrombolytic therapy of acute STIEMI patients after PCI

Objective To discuss the feasibility mechanism of the thrombolytic therapy with acute STEMI patients after PCI. Methods According to the most pathologic features of the acute STEMI patients is due to the instability of the atheromatous plaque, bleeding and burst into the lumen thrombosis, make this a lumen occlusion, to analysis around where the thrombosis to go after＇PCI. Results Patients with acute STEMI may not Complete recovery in situ after PC1, more or less with small patches, this beside relation with the guidewire operation, the instability of patch itself to cause broken. Conclusion Patients with acute STEMI after PCI without contraindication to thrombolytic therapy is feasible in theory.
