A 46-year-old male presents to the acute cardiology clinic with palpitations and exertional dyspnea. He recently had a haematology appointment where he received the good news that his course of anthracycline-based chemotherapy for Acute Myeloid Leukaemia was successful and that he was now in remission. He also has a past medical history of essential tremor, for which he takes propranolol 40mg TDS and ulcerative colitis. He was recently admitted to hospital a few weeks ago, where he was treated for a viral respiratory tract infection. Nasal swab from that admission was positive for Coxsackie A Virus. He also mentions that he smokes cocaine twice weekly with friends. ECG reveals sinus tachycardia. A TTE has been requested. The consultant cardiologist suspects acute myocarditis.
