急性冠状动脉综合征心电图与冠状动脉造影的分析

Analysis of electrocardiogram and coronary arteriography on patients with acute coronary syndrome

目的 探讨临床心电图 (ECG)改变与冠状动脉病变部位的关系。方法 对 10 5例临床初诊为急性冠状动脉综合症 (ACS)病人的心电图 (ECG)与冠状动脉造影 (CAG)结果进行回顾性分析。结果 临床初诊的ACS病例中 ,冠状动脉存在有意义狭窄者 84例 ,未见明显狭窄病变 2 1例 ,占 2 5 %。非ST段抬高的ACS以多支 ,中、重度血管病变为主 ,ST段抬高的心肌梗死前壁系统以前降支病变或合并多支血管病变为主 ,下壁系统以右冠动脉病变合并多支血管病变为主。结论 ECG可反映当时动脉粥样斑块破裂伴血栓形成、血流阻断血管的对应病变。CAG为了解冠状动脉病变部位、程度 。

Objective To investigate the relation between clinical change of ECG and lesion location of coronary artery.Method Analyze ECG and CAG of 105 patients who were diagnosed of ACS.Results Among all the patients with ACS,84 patients' coronary artery was found with significant stenosis,while 21 patients' was not found evident stenosis,occupying 25%.No ST-segment elevation ACS(UA+NSTEMI) can be found mainly in several vessels,and moderate,severe degree.ST-segment elevation myocardial infarction(STEMI) can be found mainly in anterior wall with both anterior descending artery lesion and several other blood vessels lesions.Inferior wall can be found mainly in right coronary artery lesion together with several other vessecular lesions.Conclusion ECG only indicates the corresponding lesion of obstructive vessels when artery atherosclerotic plaques rupture and thrombosis.CAG provides objective basis for understanding the location of coronary artery lesion,degree and carrying out intervenient therapy earlier.
