Late presentation of myocardial infarction (MI) during the COVID-19 pandemic.

A 65-year-old man presented to emergency department with progressive worsening dyspnoea, which was preceded by crushing, substernal chest pain 3 weeks prior that lasted for over 2 days. At the time the patient thought that this was a symptom of COVID-19 so he stayed at home and self-quarantined, until his symptoms worsened to the point of needing hospitalisation. The patient was found to have had myocardial infarction, with coronary angiography showing 100% occlusion of the Left Anterior Descending artery (LAD). Medical management was recommended given late presentation and risk of reperfusion injury.
