摘要
扩张型心肌病常合并心房颤动,但该类患者发生急性ST段抬高型心肌梗死在临床上非常罕见。该文报道了1例因急性ST段抬高型心肌梗死就诊的患者,急诊冠状动脉造影结果为前降支中段闭塞,予血栓抽吸后再通,未植入冠状动脉支架。1周后复查冠状动脉造影前降支未见明显狭窄。行血管内超声提示前降支未见明显斑块及管腔狭窄。结合心脏超声、心电图结果可诊断扩张型心肌病合并阵发性心房颤动,故推测为冠状动脉血栓栓塞导致AMI。
Dilated cardiomyopathy is constantly complicated with atrial fibrillation. However, the incidence of ST-segment elevation myocardial infarction is extremely low in patients with dilated cardiomyopathy complicated with atrial fibrillation in clinical practice. In this article, one case of ST-segment elevation myocardial infarction admitted to our hospital was reported. Emergency coronary angiography demonstrated the occlusion of the middle segment of the anterior descending artery, recanalization after thrombus aspiration, and no coronary stent was implanted. One week later, coronary angiography revealed no significant stenosis in the anterior descending artery. Intravascular ultrasound showed no evident plaque or stenosis of the anterior descending branch. The patient was diagnosed with dilated cardiomyopathy complicated with paroxysmal atrial fibrillation based upon the results of echocardiography and electrocardiography. Therefore, it is speculated that coronary artery embolism leads to the incidence of acute myocardial infarction.
