Spontaneous coronary artery dissection (SCAD) is an important cause of myocardial infarction in patients of younger age without typical atherosclerotic risk factors and can present with ventricular arrhythmia such as ventricular tachycardia (VT) or ventricular fibrillation (VF). Electrical storm (ES) is defined as greater than or equal to 3 episodes of VT or VF occurring within 24 hours.
A healthy 38-year-old-male developed chest pain while exercising at the gym and presented to the emergency department unresponsive in a ventricular arrhythmia defined as ES. The patient's cardiac arrest was initially refractory to standard defibrillation and Advanced Cardiac Life Support medications. He was ultimately diagnosed with SCAD of the left anterior descending artery, which was stented. The patient survived neurologically intact after a 13-day hospital stay.
Spontaneous coronary artery dissection is a significant cause of acute coronary syndrome and occurs in healthier patients without cardiac risk factors. Electrical storm represents a unique manifestation of SCAD. Emergency physicians should maintain a heightened suspicion for SCAD for accurate diagnosis and treatment.
自发性冠状动脉夹层(SCAD)是无典型动脉粥样硬化危险因素的年轻患者发生心肌梗死的重要原因,可表现为室性心律失常,如室性心动过速(VT)或室性颤动(VF)。电风暴(ES)定义为24小时内发生3次或3次以上的VT或VF。
一名38岁健康男性在健身房锻炼时出现胸痛,随后以定义为ES的室性心律失常被送至急诊科,当时已无反应。患者的心脏骤停最初对标准除颤和高级心脏生命支持药物治疗无效。他最终被诊断为左前降支动脉SCAD,并接受了支架置入术。患者在住院13天后神经功能完好地存活下来。
自发性冠状动脉夹层是急性冠状动脉综合征的重要原因,发生于无心脏危险因素的健康患者。电风暴是SCAD的一种独特表现。急诊医生应高度怀疑SCAD,以进行准确的诊断和治疗。
