Hi my brother had a by-pass three years ago and has been developing angina type symptoms over the last two years. Yesterday we took him for an angiogram and he has been told that two out of the three new arteries are fully blocked. They said they cannot be re-done, the only hope is to see if there is enough blood supply getting through one of them to try to put in a stent. He asked what would happen if they couldn`t, and it more or less seems his outlook is poor. Can anyone give any advice on this situation please?
