After only 90 minutes of chest pain, the first troponin was unsurprisingly in the normal range at 11ng/L (normal <26 in males and <16 in females), so the emergency physician waited for repeat troponin. Chest pain still persists. Paged cardiology 0800: patient complains of chest pain. Cardiology aware.
