Hibernating myocardium is an uncommon clinical state involving persistently impaired myocardial function. A 61-year-old man was admitted because of vasospastic angina. Coronary angiography revealed coronary artery dissection in the midportion of the right coronary artery, and segmental vasoconstriction was evoked by acetylcholine. In this patient, hibernating myocardium in the dissected region was clearly demonstrated by dipyridamole thallium-201 imaging. This report describes the first documented case of hibernating myocardium associated with coronary artery dissection, and the usefulness of dipyridamole thallium-201 imaging in the assessment of this state. Coronary artery spasm might be relevant to the etiology of coronary artery dissection.
冬眠心肌是一种罕见的临床状态，表现为心肌功能持续受损。一名61岁男性因血管痉挛性心绞痛入院。冠状动脉造影显示右冠状动脉中段存在冠状动脉夹层，乙酰胆碱诱发节段性血管收缩。在该患者中，双嘧达莫铊-201显像清晰显示了夹层区域的冬眠心肌。本报告描述了首例有记录的与冠状动脉夹层相关的冬眠心肌病例，以及双嘧达莫铊-201显像在评估这种状态中的作用。冠状动脉痉挛可能与冠状动脉夹层的病因有关。
