Spontaneous coronary artery dissection (SCAD) is increasingly recognized as an important cause of acute coronary syndrome (ACS) and myocardial infarction (MI) in individuals with few or no known atherosclerotic risk factors. While systemic autoimmune inflammatory disorders are associated with precipitating SCAD, the role of infection-induced systemic inflammation in SCAD is not well defined. We present the case of a 49-year-old Caucasian woman with ST-elevation myocardial infarction (STEMI) diagnosed as SCAD from a severe systemic inflammatory response related to disseminated blastomycosis. Punch biopsy of a skin lesion and synovial fluid culture confirmed . This case suggests the possibility of systemic infection-induced inflammation as a precipitating factor in SCAD pathogenesis similar to autoimmune inflammatory disorders.
Recognize the role of systemic inflammation from severe infection as a possible cause of spontaneous coronary artery dissection (SCAD).Recognize that cardiac involvement is rare in blastomycosis.Coronary revascularization may be required in SCAD for haemodynamic instability, ischaemic chest pain progression, and myocardium at risk.
自发性冠状动脉夹层(SCAD)越来越被认为是急性冠状动脉综合征(ACS)和心肌梗死(MI)的重要原因,这些患者几乎没有或没有已知的动脉粥样硬化危险因素。虽然全身性自身免疫性炎症性疾病与SCAD的发生有关,但感染引起的全身性炎症在SCAD中的作用尚不清楚。我们报告一例49岁白种女性,因播散性芽生菌病导致严重全身炎症反应,诊断为ST段抬高型心肌梗死(STEMI)合并SCAD。皮肤病变的打孔活检和滑液培养确诊。该病例提示全身性感染诱导的炎症可能是SCAD发病机制中的促发因素,类似于自身免疫性炎症性疾病。
认识到严重感染引起的全身性炎症可能是自发性冠状动脉夹层(SCAD)的原因。认识到芽生菌病中心脏受累罕见。对于SCAD患者,若出现血流动力学不稳定、缺血性胸痛进展及心肌处于危险状态,可能需要进行冠状动脉血运重建。
