Data for: STEMI in coronary bridging: An unusual scenario

A 48 year old gentleman presented in the ED with anginal pain of 2 hours duration. Electrocardiogram showed anterior wall ST elevation myocardial infarction (STEMI) and was taken up for primary percutaneous coronary intervention (PPCI). Angiogram showed total occlusion of mid left anterior descending (LAD) artery. Plain only balloon angioplasty (POBA) to LAD revealed the coronary occlusion in a region of coronary bridging. STEMI in a bridged coronary is an unusual clinical scenario and needs a prudent approach for effective management.

一名48岁男性患者因持续2小时的心绞痛就诊于急诊室（Emergency Department，ED）。心电图检查提示前壁ST段抬高型心肌梗死（ST-segment elevation myocardial infarction，STEMI），随后收治行直接经皮冠状动脉介入治疗（primary percutaneous coronary intervention，PPCI）。冠状动脉造影显示左前降支（left anterior descending artery，LAD）中段完全闭塞。对左前降支实施单纯球囊扩张术（plain old balloon angioplasty，POBA）时，发现该闭塞区域存在冠状动脉肌桥。合并冠状动脉肌桥的ST段抬高型心肌梗死属于罕见临床场景，需采取审慎的诊疗策略以实现有效管理。
