Coronary artery ectasia is an infrequent finding seen in a localized or diffuse fashion in patients undergoing coronary angiogram. This angiographic entity is attributed to coronary artery atherosclerosis. The ectatic coronary artery segment may be a culprit and perpetuate the thrombus formation in patients with acute myocardial infarction due to the altered normal laminar flow and deranged platelet and endothelial activation. Besides, it may lead to slow flow/no-reflow during the percutaneous coronary intervention and constitutes a significant management challenge. In this article, we report three patients with ST-segment elevation myocardial infarction from the culprit ectatic infarct-related artery and discuss the various management strategies.
冠状动脉扩张是一种不常见的发现，在接受冠状动脉造影的患者中以局部或弥漫的方式出现。这种血管造影实体归因于冠状动脉粥样硬化。扩张的冠状动脉段可能是罪魁祸首，并由于正常层流改变和血小板及内皮激活失调，导致急性心肌梗死患者血栓形成持续存在。此外，它可能导致经皮冠状动脉介入治疗期间血流缓慢/无复流，并构成重大管理挑战。本文报告了 3 例 ST 段抬高型心肌梗死患者，其罪犯为扩张的梗死相关动脉，并讨论了各种处理策略。
