摘　　要：目的:分析并评价急性冠状动脉综合征(ACS)患者心电图U波倒置与冠状动脉病变之间的相关性。方法:经冠状动脉造影诊断为ACS患者86例,根据心电图U波倒置与否分为U波倒置组和U波非倒置组;比较2组各冠状动脉病变指标差异。结果:38例患者存在U波倒置,48例患者无U波倒置。U波非倒置组不稳定型心绞痛的发生率明显高于U波倒置组(P<0.01),而ST段抬高心肌梗死的发生率低于U波倒置组(P<0.01)。U波倒置组与U波非倒置组比较,E/A比值减小,左心室射血分数值减小(P<0.01)。U波倒置组主要表现为冠状动脉中度与重度狭窄,U波非倒置组主要表现为无明显病变与轻度狭窄,2组差异有统计学意义(P<0.01)。2组冠状动脉病变表面形态差异有统计学意义(P<0.01)。U波倒置组的左主干与左前降支两支病变发生率均高于U波非倒置组(P<0.01和P<0.05),而2组的左回旋支与右冠状动脉两支的病变发生率差异无统计学意义(P>0.05)。2组在单支、双支和多支冠状动脉病变发生率差异有统计学意义(P<0.01)。U波倒置深度在冠状动脉病变支数及狭窄程度间差异均有统计学意义(P<0.01),而在冠状动脉病变表面形态间差异无统计学意义(P>0.05)。结论:心电图U波倒置情况能够有效反映出ACS患者的冠状动脉病变程度。Objective：To analyze the relationship between U wave inversion and coronary lesions in patients with acute coronary syndrome. Methods：Eighty-six ACS patients diagnosed by coronary angiography were divided into the U wave inversion group and non- U wave inversion group according to the U wave of electrocardiogram. The index of different coronary artery lesions between the two groups were compared. Results ：The U wave inversion in 38 cases and non-U wave inversion in 48 cases were identified. The incidence of UA and ST segment elevation myocardial infarction in non-U wave inversion group were significantly more and less than those in U wave inversion group,respectively （ P 〈 0.01 ）. Compared with non-U wave inversion group, the value of E/A and LVEF in U wave inversion group decreased（P 〈 0.01 ）. U wave inversion group was mainly characterized by moderate and severe stenosis, no obvious lesion and mild stenosis in non-U wave inversion group were identified, and the differences of those were statistically significant （P 〈 0.01 ）. The difference of the surface morphology of coronary lesions between two groups was statistically significant（ P 〈 0.01 ）. The incidence in left main（LM） and left anterior descending（LAD） in U wave inversion group were higher than those in non-U wave inversion group （P 〈 0.01 ）, and the differences of the incidence of left circumflex and right coronary artery（RCA） between two groups were not statistically significant（P 〉 0.05 ）. The differences of the incidence of the single, double and three lesions vessels between two groups were statistically significant（ P 〈 0.01 ）. The differences of the incidence of U wave inversion depth, coronary lesion vessels and degree of stenosis between two groups were statistically significant （ P 〈 0.01 ）, the difference of the surface morphology of coronary lesions between two groups was not statistically significant（ P 〉 0.01 ）. Conclusions： ECG U wave inversion in patients with ACS c
