Most revascularization studies on acute myocardial infarction have included patients who have ST-segment elevation or new-onset left bundle branch block. However, the characteristics of patients who have non-ST-segment elevation acute myocardial infarction and who have undergone angiographic analysis of their infarct-related arteries have not been adequately described. This study suggests that these patients are likely to have had coronary bypass surgery (odds ratio 4.58, 95% confidence interval 1.83 to 11.5, p = 0.0012) and that circumflex artery occlusions are more likely to present as non-ST-segment elevation than as acute myocardial infarction with ST-segment elevation and/or left bundle branch block (odds ratio 2.91, 95% confidence interval 1.62 to 5.22, p = 0.0003).
大多数关于急性心肌梗死的血运重建研究纳入的患者均有ST段抬高或新发左束支传导阻滞。然而，对于非ST段抬高型急性心肌梗死且已对梗死相关动脉进行血管造影分析的患者特征，尚未得到充分描述。本研究表明，这些患者很可能接受过冠状动脉搭桥手术（比值比4.58，95%置信区间1.83至11.5，p = 0.0012），而且与ST段抬高型急性心肌梗死和/或左束支传导阻滞相比，回旋支动脉闭塞更有可能表现为非ST段抬高型（比值比2.91，95%置信区间1.62至5.22，p = 0.0003）。
