Hi last year I was diagnosed with heart failure and had Open Heart Surgery and now my memory is very bad!! I am very concerned about this and have told the GP and my Cardio Consultant. The consultant said it could b the machine that pumps your blood around when they have to stop your heart to operate??!! I then looked it up online and it looks like it happens a lot?!! As anybody came across this before? I am worried that it could b the start of Dementia though, and things are getting very difficult to cope with the home and esp paying bills as I have no support and live on my own!
