【摘要】 目的 探讨冠脉痉挛与变异型心绞痛(VA)和急性心肌梗死(AMI)的关系。方法 对30例AMI和14例VA患者施行冠状动脉造影(CAG)，以冠脉狭窄>50%为CAG阳性。结果 在30例AMI患者中有4例CAG正常，在14例VA中，CAG正常2例，狭窄程度在50%～90%的12例。结论 本文结果提示，冠脉痉挛在VA和AMI的发病中起着十分重要的作用。冠脉痉挛不仅可以发生在有严重狭窄的冠状动脉，亦可以发生于造影正常的冠状动脉。

【Abstract】 Objective To investigate the relationship between coronary artery spasm and variant angina (VA) and acute myocardial infarction (AMI). Methods Coronary arteriography (CAG) was performed in 30 patients with AMI and 14 with VA. Coronary artery stenosis >50% was considered as CAG positive.Results Four of 30 AMI and two of 14 VA had completely normal coronary arteriograms, while 12 of the 14 VA had coronary stenosis from 50% to 90%. Conclusion The results indicate that coronary artery spasm was an important role in VA and AMI, and coronary spasm not only occur in those had insignificant coronary artery disease, but also can appear in completely normal coronary artery.
