The authors report a case of a 31 year old young man who suffered acute myocardial infarction and was subjected to early treatment with streptokinase. The immediate follow-up showed a complete recanalization of the infarct-related vessel, without any identifiable obstructive lesion on coronary arteriography. Related to this angiographic finding, common in myocardial infarction in the young adult, the authors debate the implicated mechanisms, focusing essentially in the relation endothelium-platelets-vasomotricity. The issue of cigarette smoking as a risk factor and its possible pathogenic implication, even in the absence of atherosclerotic plaque, is also approached.
作者报告了一例31岁青年男性急性心肌梗死患者，该患者接受了链激酶早期治疗。即时随访显示梗死相关血管完全再通，冠状动脉造影未发现任何可识别的阻塞性病变。针对这一在青年成人心肌梗死中常见的血管造影结果，作者探讨了相关机制，主要聚焦于内皮-血小板-血管舒缩功能之间的关系。文中还探讨了吸烟作为危险因素的问题及其可能的致病影响，即使在没有动脉粥样硬化斑块的情况下。
