In this study, 6 patients underwent angiographic assessment prior to and subsequent to acute myocardial infarction. The mean inter-angiographic interval was 36 months and the mean infarct to angiography interval was 8 months. Left ventricular ejection fraction decreased from 0.69 to 0.45 after infarction. The degree of left ventricular dysfunction after infarction did not necessarily relate to the site or type of infarction. All patients had significant progression of their coronary lesions with occlusion of a major coronary vessel in the interval. Coronary artery occlusion with infarction produces a variable degree of damage and subsequent left ventricular dysfunction.
在本研究中，6例患者在急性心肌梗死前后接受了血管造影评估。血管造影的平均间隔时间为36个月，梗死至血管造影的平均间隔时间为8个月。梗死后左心室射血分数从0.69降至0.45。梗死后左心室功能障碍的程度不一定与梗死部位或类型相关。所有患者的冠状动脉病变均有显著进展，在此期间主要冠状动脉血管发生闭塞。冠状动脉闭塞伴梗死会产生不同程度的损害及随后的左心室功能障碍。
