A 48-year-old man presented to hospital with prolonged ischaemic chest pain. No electrocardiographic or enzymic changes of acute myocardial infarction were found. Angiography performed five days later showed 75% luminal narrowing of the proximal left anterior descending (LAD) coronary artery, but no other significant abnormality. On the following day, he developed an acute anterior myocardial infarct. On repeat angiography, undertaken within 2 1/2 hours of the onset of symptoms, the LAD was found to be totally occluded. A guidewire was immediately passed through the occlusion, and streptokinase was infused through the left coronary artery for approximately 30 minutes. The vessel became patent immediately after the insertion of the guidewire, and remained so during the infusion of streptokinase. Coronary artery bypass graft surgery was successfully undertaken after the completion of the procedure.
一名48岁男性因长时间缺血性胸痛入院。未发现急性心肌梗死的心电图或酶学改变。五天后进行的血管造影显示左前降支（LAD）近端管腔狭窄75%，但无其他明显异常。次日，他发生了急性前壁心肌梗死。在症状发作后2个半小时内再次进行血管造影时，发现LAD完全闭塞。立即将导丝穿过闭塞处，并通过左冠状动脉注入链激酶约30分钟。插入导丝后血管立即通畅，并在注入链激酶期间一直保持通畅。该操作完成后成功进行了冠状动脉旁路移植术。
