Quick update, unfortunately had to return to hospital early ours on Monday due to chest pains and dizziness. Took me off beta blockers due to low Blod pressure, and monitored, had another more painful episode requirining nitro infusion to dialate artuaries which worked. Then wait for angiogram to check stents all ok and double check heart. I had angiogram at 17:30 today and consultant said is good and felt subsequent pain may have been due to heart muscle bruising from heart attack and earlier smaller ones.
So it's home tomorrow with a return for a check up in 2 months.
Once again thanks for everyone's support.
