英文摘要：

A 49-year-old premenopausal woman was transferred to an urgent coronary angiography complaining of acute onset chest pain for four hours.Coronary angiography revealed interrupted flow in the far-end of left anterior descending（LAD） and left circumflex（LCX） and obtuse marginal branch with normal flow right coronary arteries.Left ventriculography showed extensive severe hypokinesis in the apical segments.The diagnoses of acute myocardial infarction（AMI） was argued to be established and pharmacotherapy was initiated.On the eighth day,the reexamination of coronary angiography showed that the interrupted flow of coronary arteries had completely recovered.Left ventriculography showed significant recovery of extensive hypokinesis in the apical segments.The diagnosis was re-evaluated and made a definite diagnosis of apical ballooning syndrome later.
