From: Chest CT examinations in patients presenting with acute chest pain: a pictorial review
A 48-year female was admitted to the ED after severe chest pain and palpitations. ECG showed transient 1-2 mm ST elevation. Cardiac biomarkers were normal. Cardiac CT was ordered for evaluation of the coronary arteries. (a) Cardiac CT performed shows a significant stenosis in the proximal LAD (arrow). (b) Invasive coronary angiography shows the same significant lesion. (c) After intracoronary administration of nitroglycerin, the lesion became non-significant. The diagnosis of coronary artery vasospasm was made, and interventional procedure was not performed
