I know nothing about medical things but I keep reading that this person suffered permanent heart muscle damage. Surely everyone who has a heart attack suffers from permanent heart muscle damage, even if they were able to get to a hospital a bit quicker? Even if a diversion had been started as soon as the passenger was diagnosed, it would probably have been at least an hour before he got specialist medical help. Would that have made a difference to his outcome? There was a Dr on board, and I can't believe that the Captain disregarded his opinion if he said a diversion was necessary. Although it looks like in the end it wasn't a life threatening situation, which is usually what we divert for.
