When the metabolic demand of the heart exceeds its oxygen supply, myocardial ischemia or infarction (MI) may occur. One of the causes of this condition is severe anemia. The type of MI associated with cases of supply-demand myocardial mismatch is usually a non-ST elevation infarction (Non-STEMI), and is most commonly seen in patients with underlying coronary artery disease. We present a case report of ST segment elevation MI (STEMI), which we believe was secondary to severe anemia, occurring in the absence of angiographically significant coronary artery stenosis or thrombosis. Coronary artery spasm was not seen. In our review of the literature we found no similar cases (MEDLINE 1966-2002).
当心脏的代谢需求超过其氧供应时，可能会发生心肌缺血或梗死（MI）。这种情况的原因之一是严重贫血。与供需性心肌不匹配病例相关的MI类型通常是非ST段抬高型梗死（Non-STEMI），最常见于患有潜在冠状动脉疾病的患者。我们报告一例ST段抬高型MI（STEMI）病例，我们认为该病例继发于严重贫血，且在血管造影未发现显著冠状动脉狭窄或血栓形成的情况下发生。未发现冠状动脉痉挛。在我们对文献的回顾中，未发现类似病例（MEDLINE 1966 - 2002）。
