Simultaneous myocardial infarction and ischaemic stroke secondary to paradoxical emboli through a patent foramen ovale.

Myocardial infarction (MI) and stroke are common acute conditions that regularly present as an emergency to hospital. Paradoxical embolism is a recognised complication of patent foramen ovale (PFO), and the literature shows that it can cause ischaemic stroke or, less frequently, acute MI. Ischaemic stroke and MI occurring simultaneously has a wide differential diagnosis, which should include a PFO, especially when occurring in young patients.
