摘要：目的：通过冠状动脉造影观察变异性心绞痛冠脉病变程度与动态心电图一过性ST段抬高的关系。方法：对46例动态心电图有一过性ST段抬高患者行冠状动脉造影检查。结果：46例变异性心绞通患者中，冠脉造影检查示冠状动脉伴有意义狭窄者共43例，其中狭窄>70%者达33例(占71%)；>70%狭窄者：ST段抬高在>0.2mV，≤0.2mV者中分别占86%(30/35)，27%(3/11)，二者差异显著(P<0.05)；在ST段抬高最长持续时间<3min者，≥3min者中分别占44%(8/18)，89%(25/28)，二者差异显著(P<0.05)。结论：变异性心绞痛更易于在有病变的冠状动脉上发生，当冠脉痉挛发生时，ST抬高的时间、高度与冠脉狭窄的程度呈正相关。

    Abstract: Objective: To study the relation of coronary stenosis and temporary ST elevation in dynamic electrocardiography in variable angina (VA).Method: Study the data of DCG and coronary artery angiography (CAG) in 46 cases with paroxysmal ST elevation in dynamic electrocardiography. Result: There are 43 patients who have significance stenosis of coronary artery through CAG in 46 patients. There were 33 cases stenosis of >75%; The percent of ST elevation ≤0. 2 mV, >0.2mV occurred cases whose coronary stenosis of >75% was 27%, 86% respectively (P<0. 05). The percent of ST elevation persisting time <3 min, ≥3 min occurred cases whose coronary stenosis of >75% was 44%, 89% respectively (P<0. 05). Conclusion: The variable angina is feasible to happen in cases with coronary artery stenosis and the persisting time and extent of ST elevation is related with stenosis degree of coronary artery. ......
