This is indeed very worrying not from a medical point of view but politically.
It looks as though he has been thrown "on the scrap heap" because of his age and this is exactly what many Americans are worried about with the Obama medicare.
Clearly the angiograms have shown multiple artery problems and a stent would be useless and that he needs Coronary Artery bypass surgery which i intimated in my first post on this thread.
Age would not be a bar to this in Europe or the U.S.A and i can only assume that his general medical condition is the reason for turning down bypass surgery.
There is no point in inserting a stent, however simple, if it would be of no value.
It may appear that i am being unreasonably hard on the NHS, but that is my opinion.
