My husband had triple bypass surgery 19 years ago when he was 45, since then he has had 4 sents put in. He had another heart attack but didnt really know he was having one in sept. They gave him a stress test which was halted half way through. He was then advised to have a angio gram to see what was going on. He had this in dec. And was told that the back artery was closed and that it was impossible to re open as in fact it had died. The other three arteries are working fine at the moment with only a slight occulsion in each one. He is in no pain but gets very tired. Our dr says that at the moment no further treatment is needed just to carry on with his medication and monitor his blood and cholesteral.
Like you I am worried as this must do something to have an adverese effect on his heart etc. I feel that we have been told to go away and stop being a nusiance. I am sorry that I do not have an answer for you but if you find out could you please let me know. Thanks gill
