Severe diffuse left anterior descending coronary vasospasm can cause ventricular fibrillation cardiac arrest even in young patients without typical risk factors for sudden cardiac death.
Case Report (n=1)
Coronary artery vasospasm is a critical, potentially fatal etiology to consider in young patients presenting with ventricular fibrillation cardiac arrest and STEMI-like electrocardiogram changes.

Alerts clinicians to fatal vasospasm risk in ED arrests; extends case evidence but leaves optimal prevention open.
This is a case of the most severe and potentially fatal complication of coronary artery vasospasm. We report a case of a 40-year-old female presenting to the emergency department (ED) via emergency medical services with chest pain. The patient experienced a ventricular fibrillation cardiac arrest while in the ED. Post-defibrillation electrocardiogram showed changes suggestive of an ST-elevation myocardial infarction (STEMI). Cardiac catheterization showed severe left anterior descending spasm with no evidence of disease. Coronary vasospasm is a consideration in the differential causes of ventricular fibrillation and STEMI seen in the ED.

Wilson et al. (2019) conducted a case report in Ventricular fibrillation cardiac arrest (n=1). Coronary artery vasospasm was evaluated. Severe diffuse left anterior descending coronary vasospasm can cause ventricular fibrillation cardiac arrest even in young patients without typical risk factors for sudden cardiac death.
