Abstract

There are few reports of acute myocardial infarction (AMI) relating to the occlusion of the conus branch, most of which are iatrogenic in nature. So far as we are concerned, this is the first case of spontaneous AMI with isolated conus branch occlusion. Electrocardiogram (ECG) showed mild elevation of ST segment in leads V(1) through V(3). Cardiac makers of myocardial infarction were positive. Right coronary angiography revealed an isolated occlusion of the conus branch. Penetration of the guidewire in the occluded lesion was attempted, and recanalization was successfully achieved. The patient was discharged without any adverse events.

摘要

关于圆锥支闭塞导致急性心肌梗死（AMI）的报道较少，其中大多数本质上是医源性的。就我们所知，这是首例孤立性圆锥支闭塞导致的自发性AMI。心电图（ECG）显示V（1）至V（3）导联ST段轻度抬高。心肌梗死的心脏标志物呈阳性。右冠状动脉造影显示圆锥支孤立性闭塞。尝试将导丝穿过闭塞病变，成功实现再通。患者出院时无任何不良事件。
