摘要
目的探讨aVR导联T波方向对急性前壁心肌梗死患者预后价值。方法将74例急性前壁心肌梗死患者,根据心电图aVR导联T波方向不同分为T波直立组(A组)和T波倒置组(B组),分析两组患者心电图、脑钠肽、C反应蛋白、冠脉造影结果及心功能变化。结果 A组以老年人居多;脑钠肽、C反应蛋白明显升高;冠脉造影提示多伴有多支血管病变,且患者LAD比较长,多呈LAD包绕型,阻塞部位多为LAD近段;患者心功能更差。结论 aVR导联T波方向对急性前壁心肌梗死患者预后评估有重要价值,值得临床重视。
Objective To investigate the value of T-wave amplitude in lead aVR in patients with acute anteriormyocardial infarction. Methods 74 patients with acute anteriormyocardial infarction were classified as a T-wave positive（group A）or T-wave negative（groupB） in aVR based upon the admission electrocardiogram. All patients were evaluated with electrocardiogram; brain natriuretic peptide; c-reactive protein; coronary angiography and heart function change. Results T-wave positive patients（group A） were older, brain natriuretic peptide and c-reactive protein were significantly increased;multivessel disease;long LAD and the proximal location of the lesion were significantly more frequent. T-wave positive patients had a lower heart function than group B. Conclusion T-wave amplitude in lead aVR are indicators of predicting the prognosis of acute anteriormyocardial infarction.
