静息心电图持续性ST段压低与冠状动脉造影的关系

Relationship between persistent resting ECG ST segment depression and coronary angiography

【目的】分析静息心电图持续性ST段压低与冠状动脉病变以及不同冠脉病变程度的关系。【方法】我院近两年拟诊断为冠心病并接受冠状动脉造影术的患者资料进行回顾性分析,统计各支冠脉病变的发生情况,不同程度冠脉病变时心电图持续性ST段压低的发生情况,分析心电图对冠心病诊断的敏感性和特异性。【结果】所有资料中冠脉造影阳性212例。心电图阳性组中,冠心病的发病率为37.4%,冠心病组中心电图ST段压低的发生率为31.6%。对不同冠脉病变程度组的患者进行分析,表明冠脉病变程度与持续性ST段压低及心脏结构的改变均无明显相关。【结论】静息心电图对冠心病的诊断价值并不高,临床依据持续性ST段压低诊断冠心病时应慎重。

【Objective】To analyze the relationship of persistent resting ECG ST-segment depression and coronary artery angiography,as well as the extent of coronary artery.【Methods】 Patients suspceted as coronary heart disease in the past two years in our hospital were chosen as study objects.The condition of different branches of coronary artery,the lesions in the coronary arteries and the incidence of persistent resting ECG ST segment depression were calculated and analyzed.【Results】There were 212 patients showed positive for coronal artery,and the others were non-coronary heart disease.The incidence of coronary heart disease was 37.4% in the group of positive ECG.There were 31.6% patients with persistent ECG ST-segment depression in the group of coronary heart disease.There was no significant correlation between the grade of CAD and persistent ECG ST-segment depression.【Conclusions】 Persistent resting ST-segment depression is not a realiable diagnostic criteria and taking it as an electrocardiographic diagnostic criteria of coronary heart disease should be careful.
