目的 :探讨急性冠状动脉综合征(ACS)患者的动态心电图(DCG)结果与患者冠脉造影(CAG)检查结果之间的关系。方法 :分析2011年7月~2014年2月在我院以接受治疗的ACS患者的临床资料。入组患者均行DCG和CAG检查,以CAG检查结果为金标准,比较两种检查结果的相关性。结果 :本研究共入组患者274例(冠脉检查为阳性),DCG检查阳性结果患者217例,阴性患者57例,阳性率为79.2%;DCG检查结果的阳性率与冠脉病变支数有着显著的相关性;DCG检查结果的阳性率与冠脉病变血管狭窄程度有着显著的相关性;DCG阳性的患者ST段抬高幅度与冠脉病变支数呈正相关的关系,而与病变血管的狭窄程度无明显相关性;DCG阳性的患者ST段抬高持续时间与冠脉病变支数、狭窄程度均呈正相关的关系。结论 :ACS患者的DCG检查结果阳性率较高,且其心电图表现与患者的冠脉病变支数、狭窄程度显著相关。
Objective: To investigate the relationship between ambulatory electrocardiogram (DCG) results and coronary angiography (CAG) in patients with acute coronary syndrome (ACS). Methods: The clinical data of ACS patients undergoing treatment in our hospital from July 2011 to February 2014 were analyzed. Patients in the group underwent DCG and CAG examination to CAG test results as the gold standard, comparing the correlation between the two test results. RESULTS: A total of 274 patients (positive for coronary artery test) were enrolled in this study. There were 217 positive cases in DCG test and 57 negative cases in 57 cases. The positive rate of DCG was significantly correlated with the number of coronary lesions Significant correlation between the positive rate of DCG test results and coronary vascular stenosis has a significant correlation; DCG-positive patients with ST segment elevation and coronary artery lesions was positively correlated with the number of lesions, and vascular stenosis There was no significant correlation between the duration of ST segment elevation and the number of coronary lesions and the degree of stenosis in DCG-positive patients. Conclusion: The positive rate of DCG in ACS patients is high, and the electrocardiographic findings are significantly correlated with the number of coronary lesions and the degree of stenosis.
