Is this the medical registrar? Situation I’m calling because I would like you to urgently review a patient who has presented acutely unwell. The patient is called Bruce Wayne, a 64 year old man, and I am concerned that he has developed an acute coronary syndrome. Background His symptoms started one hour ago including central chest pain radiating to the left arm and jaw with associated dyspnoea. He has multiple cardiac risk factors including hypertension managed with ramipril and type 2 diabetes managed with metformin. He also has a significant smoking history. An ECG was performed and showed ST elevation in the anterior and lateral leads. The chest x-ray and ABG were normal. Assessment The patient currently has a NEWS score of 13 due to being tachycardic at 140 bpm, hypotensive with a blood pressure of 90/50 despite a 500ml crystalloid STAT bolus. Respiratory rate is 28 and oxygen saturations are 92% on 100% oxygen via a 15L non-rebreather mask. He is alert and afebrile. I have started cardiac monitoring and given an antiemetic. I have also given aspirin 300mg, clopidogrel 300mg and morphine 5mg. I am still awaiting the results of blood tests including troponin levels. Recommendation This patient has suffered an anterolateral STEMI and needs an urgent assessment and should be transferred to the catherization lab for PCI. I would like to ask if there is anything else that you would like me to do for the patient. Would you also be able to come and review him as soon as possible, please?
