A 50 year old man was woken up 1 hour ago by sudden onset, severe retrosternal chest pain radiating to the jaw, neck, and left arm. He went to see his primary care practitioner, who obtained an ECG and said that he was having a 'heart attack'.
He was then administered Aspirin and sublingual Nitroglycerin and rushed to hospital. Now, at presentation, his chest pain has subsided completely.
His medical history is unremarkable, while a full blood count and chest x-ray are normal.
