目的探讨心电图aVR导联ST段抬高对急性前壁心肌梗死患者临床预后的价值。方法根据心电图aVR导联ST段变化,将78例急性前壁心肌梗死患者分为抬高组41例和无抬高组37例。分析两组患者的心电图、冠状动脉造影及心血管事件发生率。结果①左主干病变9例,ST段抬高组8例(19.51%)、ST段无抬高组1例(2.7%),两组统计有显著性差异(P<0.05);多支冠状动脉血管病变44例,ST段抬高组28例(68.29%)、ST段无抬高组16例(43.24%),两组统计有显著性差异(P<0.05);②心血管事件发生率12例,ST段抬高组8例(19.51%)、ST段无抬高组4例(10.81%),两组有显著性差异(P<0.01)。结论aVR导联ST段抬高对预测急性前壁心肌梗死患者的预后有重要的价值。
Objective To investigate the value of aVR lead ST segment elevation on the prognosis of patients with acute anterior myocardial infarction. Methods According to the change of ST segment of aVR lead in ECG, 78 patients with acute anterior myocardial infarction were divided into elevation group (n = 41) and non-elevation group (n = 37). The electrocardiogram, coronary angiography and incidence of cardiovascular events were analyzed in both groups. Results ① There were 9 cases of left main disease, 8 cases (19.51%) in ST segment elevation and 1 case (2.7%) in ST segment without elevation. There was significant difference between the two groups (P <0.05) There were 44 cases of vascular disease, 28 cases (68.29%) of ST segment elevation, 16 cases (43.24%) of ST segment without elevation, there was significant difference between two groups (P <0.05); ②The incidence of cardiovascular events was 12 For example, there were 8 cases (19.51%) in ST segment elevation group and 4 cases (10.81%) in ST segment without elevation. There was significant difference between the two groups (P <0.01). Conclusions The aVR lead ST segment elevation is of great value in predicting the prognosis of patients with acute anterior myocardial infarction.
