摘要 目的探讨心绞痛发作时异常心电图假性正常化的临床意义。方法回顾性分析1386例心绞痛患者的临床资料,观察心绞痛发作时ST-T改变。结果1386例中有32例(2.31%)心绞痛发作时原来心电图异常的ST-T出现假性正常化,其中经治疗好转22例(68.75%),发生急性心肌梗死8例(25.00%),死亡2例(6.25%);而1354例无假性正常化患者中,好转1226例(90.55%),发生急性心肌梗死92例(6.79%),死亡32例(2.66%),差异均有显著性意义(χ2=47.12,19.03,5.54,P<0.01)结论心绞痛发作时心电图假性正常化应视为严重心绞痛发作,且易发生急性心肌梗死或猝死;应尽早有效解除冠状动脉痉挛、抗凝治疗,并积极控制危险因素。 Objective To explore clinical significance of normalization of abnormal ST-T on electroeardiogram(ECG) during angina peetoris(AP) attacking. Methods ST-T changes on ECG and clinical data of 1386 patients with AP were analyzed retrospectively. Results In 1386 patients with AP, 32 cases had normalization of abnormal ST-T on ECG during AP attack. Of them, 22 patients had clinical symptom relieved after treatment (68.75%), 8 patients developed acute myocardial infarction (AMI)(25%) and 2 patients died(6.25%). However, in 1354 patients without normalization of abnormal ST-T, 1226 patients had clinical symptom improved after treatment (90.55%), 92 patients progressed to AMI (6.79%) and 32 patients died (2.66%). There were significant differences in prognosis between patients with and without normalization of abnormal ST-T on ECG(X^2=-47.12, 19.03,5.54,P〈0.01). Conclusion Normalization of abnormal ST-T on ECG during AP attack may be indicator of severity of disease and patients with such changes should receive active treatment to prevent AMI and sudden death.
