急性脑梗死患者心电图缺血性ST-T改变与预后的关系

Relationship between electrocardiography ischemic ST-T segment changes and prognosis in acute cerebral infarction

目的:探讨脑梗死急性期心电图缺血性ST-T改变与预后的关系。方法:77例急性脑梗死患者分别于入院时及7 d后做心电图检查,根据有无缺血性ST-T改变分为持续缺血性ST-T改变组、短暂缺血性ST-T改变组和无缺血性ST-T改变组。分析3组患者病情轻重、梗死灶大小及与预后的关系。结果:持续缺血性ST-T改变组病情重、梗死灶大、预后差,3组预后比较差异均有统计学意义(P<0.05～P<0.01)。结论:心电图缺血性ST-T改变可以反映急性脑梗死患者的病情轻重、梗死灶大小及预后,动态观察并及时治疗可改善预后。

Objective：To investigate the relationship between electrocardiography（ECG） ischemic ST-T segment changes and prognosis in patients with acute cerebral infarction. Methods：ECG was checked on admission and 7 days later in 77 patients with acute cerebral infarction.According to the ECG ischemic ST-T segment changes,patients were divided into three groups：continuing ECG ischemic ST-T segment changes group,temporary ECG ischemic ST-T segment changes group,no ECG ischemic ST-T segment changes group.Then the relationship between ECG ischemic ST-T segment changes and disease condition,size of infarction and prognosis were analyzed. Results：Compared with the other two groups,continuing ECG ischemic ST-T segment changes group showed severer condition,larger size of infarction,poorer prognosis,and there were the significant differences（P0.05 to P0.01）. Conclusions：The changes of ECG ischemic ST-T segment could be as an indication for disease condition,infarction size and prognosis.A dynamic observing of ECG ischemic ST-T segment changes and timely therapy are advantageous for patients with acute cerebral infarction.
