Given this man's presentation, what is the most likely cause of his impaired liver function tests?

A 55-year-old man is brought into the emergency department by the paramedics. He collapsed on the street suffering from a myocardial infarction and subsequently resuscitated following a cardiac arrest. Follow up blood tests are sent and the results show impaired liver function. He regularly has liver function tests as he is on a statin, and at his appointment last week they had been normal. There is nothing to note on examination and he is currently not complaining of any pain.
