心电图与冠状动脉造影在急性非ST段抬高型心肌梗死中的应用

目的对比分析急性非ST段抬高型心肌梗死患者的心电图与冠状动脉造影结果。方法选择2013年1月至2015年06月我院接诊的110例急性非ST段心肌梗死患者作为研究对象。所有患者均进行标准12导心电图和冠状动脉造影检查,根据检查结果,按照QRS时限、ST段压低的导联数以及程度、T波倒置分为四组,根据记录信息对心电图和冠状动脉造影的结果进行比较分析。结果当QRS≥100 ms时,冠状动脉造影3支及左主干病变数为42.7%,和QRS100 ms相比,差异具有统计学意义(P0.05),但单支和双支的病变比较差异无统计学意义(P0.05);当ST段下移≥1 mm时,冠状动脉造影3支及左主干病变数为53.33%,明显高于ST段下移1 mm,但两组间单支和双支的病变例数相比,差异无统计学意义(P0.05);当导联数≥6时,冠状动脉造影3支及左主干病变数为75.56%,明显高于导联数6时,两组中单支和双支的病变例数比较差异无统计学意义(P0.05);T波倒置对冠脉血管病变无影响(P0.05)。结论急性非ST段抬高型心肌梗死患者的心电图诊断结果多符合冠状动脉造影结果,可从ST段下移程度、QRS时限以及ST段压低的导联数等判断是否存在冠状动脉病变,为采取有效的治疗措施提供了可靠参考。

Comparative Analysis of Electrocardiogram and Coronary Angiography Results on Acute Non ST Segment Elevation Myocardial Infarction

Objective To compare the results of ECG and coronary angiography in patients with acute non ST segment elevation myocardial infarction.Methods 110 cases of acute non ST segment myocardial infarction from January 2013 to June 2015 in our hospital act as the research object.All patients were given the standard 12 lead ECG and coronary angiography,according to the results of the inspection,in accordance with the QRS duration and ST segment depression lead number and degree,T wave inversion,they were divided into four groups,according to the information recorded on ECG and coronary angiography results were compared.Results When QRS was larger than 100 ms,coronary angiography 3 lesion and left main lesion were 42.7％,compared to QRS smaller than 100 ms,the difference was statistically significant(P ＜ 0.05),but there was no significant difference in single and double branch lesion (P ＞ 0.05);when the ST segment is not less than 1 mm and coronary angiography in 3 and left main lesion number was 53.33％,it was significantly higher than that of ST segment depression less than 1 mm,but compared their single and double vessel lesions,the difference was not statistically significant (P ＞ 0.05);when the number of leads was higher than 6,the 3 branches of coronary angiography and left main lesion was 75.56％,it was significantly higher than the number of leads less than 6,it had no significant differencebetween single and double lesions (P ＞ 0.05);T wave inversion has no effect on the severity of coronary artery disease (P ＞ 0.05).Conclusion Acute non ST segment elevation myocardial infarction patients'electrocardiogram diagnosis results is in line with the results of coronary artery angiography,we can diagnosecoronary artery disease from the degree of ST segment depression,QRS duration and ST segment depression,it can provide a reliable reference for taking effective treatment measures.
