摘要
目的探讨分析心绞痛患者异常心电图U波与冠状动脉病变的相关性。方法选择我院收治的136例接受冠脉造影的心绞痛患者,收治时间为2019年6月至2020年12月期间,以患者常规心电图检测结果作为分组标准,其中U波正常患者70例为对照组,U波倒置患者66例为研究组,对两组患者的相关资料进行对比,并探讨其与患者冠状动脉造影检测结果的相关性。结果共136例患者,其中U波异常66例,占比48.53%;研究组与对照组患者的合并症、心绞痛类型等一般资料对比,不存在统计学差异(p>0.05);研究组患者冠状动脉病变狭窄程度、数量以及形态,与对照组患者相比存在统计学差异(p<0.05);研究组组内不同狭窄程度、病变支数U波倒置深度对比,存在统计学差异(p<0.05);相关性分析结果显示,心绞痛患者病变狭窄程度、病变支数与心电图U波异常、以及倒置深度存在相关性(p<0.05)。结论心绞痛患者U波异常倒置,与患者冠状动脉病变存在相关性,U波改变有助于预测患者冠状动脉病变的程度。
Objective To explore and analyze the correlation between abnormal ECG U wave and coronary artery disease in patients with angina pectoris. Methods In this study, 136 patients with angina pectoris receiving coronary angiography in our hospital were selected from June 2019 to December 2020. Routine ECG test results of patients were taken as the group criteria, among which 70 patients with normal U wave were enrolled as the control group, and 66 patients with inverted U wave were enrolled as the study group. The correlative data of the two groups of patients were compared, and the correlation between them and the results of coronary angiography was discussed.Results One hundred and thirty-six patients, 66 patients with abnormal U wave, accounting for 48.53%. There was no significant difference in complications, angina pectoris type and other general data between the study group and the control group(p>0.05). The degree, number and morphology of coronary artery stenosis in the study group were significantly different from those in the control group(p<0.05). There were significant differences in the U-wave inversion depth among different stenosis degree and lesion count in the study group(p<0.05). Correlation analysis results showed that the degree of lesion stenosis and lesion count were correlated with abnormal U wave and inversion depth of ECG in patients with angina pectoris(p<0.05). Conclusions The abnormal U-wave inversion of ECG in patients with angina pectoris is correlated with coronary artery disease. The detection of U-wave in ECG can predict the degree of coronary artery disease in patients with angina pectoris, which has obvious clinical value.
