Spontaneous coronary artery dissection (SCAD) represents a rare cause of acute coronary syndromes with complex pathohysiology. We briefly describe a 50-year-old woman, without traditional cardiovascular risk factors, hospitalized for an acute ST-elevation myocardial infarction and treated with thrombolytic therapy. Notably, the patient was on oral contraceptives for the past 10 years. Coronary angiography showed a dissection of the distal left anterior descending artery. She was treated conservatively and her clinical status improved without evidence of continuing ischemia, while a repeated catheterization 6 months later showed a complete resolution of the dissection. It has been speculated that the female hormones may be responsible for the increased incidence of SCAD among women particularly during the peripartum period or during the exogenous administration of such agents. A systematic review of the literature revealed 4 further cases reporting an association of SCAD with oral contraceptive use.
自发性冠状动脉夹层(SCAD)是急性冠状动脉综合征的一种罕见病因,其病理生理学机制复杂。我们简要描述一名50岁女性,她没有传统的心血管危险因素,因急性ST段抬高型心肌梗死住院并接受了溶栓治疗。值得注意的是,该患者在过去10年一直服用口服避孕药。冠状动脉造影显示左前降支远端夹层。她接受了保守治疗,临床状况改善,无持续缺血迹象,而6个月后重复进行的心导管检查显示夹层完全消失。据推测,女性激素可能是导致女性SCAD发病率增加的原因,尤其是在围产期或外源性使用此类药物期间。对文献的系统综述又发现了4例报告SCAD与口服避孕药使用有关的病例。
