目的观察静脉溶栓后早期T波倒置对冠脉再通的诊断价值。方法急性心肌梗塞进行静脉溶栓患者30例,观察溶栓后T波变化而分成T波倒置组和未倒置组,比较二组患者的冠脉再通;ST段变化及心肌CK酶峰。结果T波倒置组冠脉再通率明显高于未倒置组,差异有高度显著性(P<001),且伴随ST段的迅速回降及酶峰时间提前。结论溶栓后24小时内T波倒置可作为判断冠脉再通的可靠指标。
Objective To observe the diagnostic value of early T wave inversion on coronary recanalization after intravenous thrombolysis. Methods Thirty patients with acute myocardial infarction undergoing thrombolysis were divided into T-wave inversion group and non-inversion group after thrombolysis. The coronary recanalization, ST-segment changes and myocardial CK enzyme peak were compared between the two groups. Results The recanalization rate of coronary artery in T wave inversion group was significantly higher than that in non - inversion group, the difference was highly significant (P <001), and accompanied with the rapid fall of ST segment and the advancement of enzyme peak time. Conclusion The inversion of T wave within 24 hours after thrombolytic therapy can be used as a reliable indicator of coronary recanalization.
