急性冠脉综合征心电图U波倒置形态改变与冠状动脉造影相关性分析

目的：探讨急性冠状动脉综合征（ACS）患者的心电图U波倒置形态改变与冠脉病变的关系.方法：选择2005-12/2009-05我院经冠状动脉造影（CAG）确诊的ACS患者69例,所有患者均进行心电图和CAG检查,记录CAG结果和心电图U波倒置形态改变并进行对比分析.结果：本组69例ACS患者中U波倒置的患者30例,无U波倒置的患者39例.U波倒置患者UA和STEMI的患病率明显低于无U波倒置患者（P〈0.05）,而NSTEMI的患病率则明显高于无U波倒置患者; U波倒置患者与非U波倒置患者相比,E值下降、A值升高、E/A下降、EF值下降,且均有统计学差异（P〈0.05）; 冠脉造影结果显示,U波倒置患者与无U波倒置患者在回旋支和右冠脉的发生率相似; 左主干和左前降支的发生率比较,U波倒置患者明显高于无U波倒置患者（P〈0.05）; U波倒置患者双支、三支病变发生率明显高于无U波倒置患者,单支病变发生率明显低于无U波倒置患者（P〈0.05）; U波倒置患者冠脉病变狭窄程度明显高于无U波倒置患者（P〈0.05）; U波倒置患者的冠脉病变表面形态以复杂病变为主,而无U波倒置患者以简单病变为主,两者比较差异具有统计学意义（P〈0.05）; 分析30例U波倒置的ACS患者的U波倒置深度与冠脉病变的关系显示：冠脉病变的支数和狭窄程度与U波倒置的深度密切相关（P〈0.05）.结论：ACS患者的心电图U波对判断患者病情及预后有重要临床价值.

Contrast analysis between U wave inversion and coronary angiography of acute coronary syndrome

AIM:To investigate the relation between U wave inversion and coronary angiography(CAG) of acute coronary syndrome.METHODS:Sixty-nine patients who were diagnosed with ACS by CAG from December 2005 to May 2009.All patents underwent CAG and electrocardiographic examination.The result of CAG and the change of ECG were recorded,compared and analyzed.RESULTS:There were 30 cases of U wave inversion and 39 cases of U wave non-inversion.The incidence of UA and STEMI were higher in the U wave inversion than in U wave...
