Abstract

Variant angina presenting acute chest pain and ST elevation on electrocardiogram accounts for an underdiagnosed scenario in acute coronary syndrome and contributes to syncope as a consequence of ventricular arrhythmia. Here,we report a case of a 48-year-old manwith a recent onset of chest pain and palpitations followed by syncope. Holter monitoring documented 2 episodes of evolving ST elevation associated with non-sustained ventricular tachycardia. Emergent cardiac catheterization indicated insignificant coronary narrowing. A non-invasive brachial artery ultrasound, which demonstrated endothelial dysfunction that was salvaged by exogenic nitrate, was used instead of intracoronary provocation. There was no clinical or electrocardiographic recurrence of variant angina after vasodilator treatment. In conclusion, variant angina represents an important but overlooked etiology for syncope. Holter monitoring facilitates the diagnostic and prognostic assessment in patients with syncope precipitated by chest pain.
