| pubmed-article:2330459 | pubmed:abstractText | We experienced two cases of primary coronary artery dissection. (Case 1) 55-year-old man had frequent episodes of chest oppression at early morning and midnight. During chest oppression, electrocardiogram showed transient ST-segment elevation in leads II, III, and a VF. Then, he was diagnosed as having angina pectoris. This diagnosis was based on the fact that he presented coronary spastic syndrome. Right coronary angiogram demonstrated an intimal flap and false lumen at segment 3, and primary coronary dissection was confirmed. (Case 2) A 27-year-old woman complained of back pain while taking a bath. Electrocardiogram showed ST-segment elevation and abnormal Q in leads V2, V3 and V4. She was diagnosed as having acute anterior wall myocardial infarction. Presence of coronary artery dissection at segment 6 was identified by left coronary angiogram. Primary coronary artery dissection is clinically diagnosed by coronary angiogram very rarely. Only 27 such cases have been reported. It was speculated that, in case 1, vasospastic angina may be associated with primary coronary artery dissection. Case 2 had primary coronary artery dissection at segment 6 of the left anterior descending artery. Thus, her clinical picture was similar to those of previously reported cases. | lld:pubmed |
