A 30-year-old woman who is known to have recurrent attacks of migraine presents to the Emergency Department complaining of central dull chest pain. She normally takes amitriptyline, and started sumatriptan for the acute attack. She has just returned from a holiday in Spain.
On examination she appears normal with all observations within normal range. Initial blood tests reveal normal haematology and biochemistry. Both D-dimer and troponin T assays are within the normal range and a chest X-ray is normal. A 12-lead electrocardiogram is unremarkable.?
