Well, as you asked
.
There's been no change in my condition. A blood test (which seemed to need a whole armful of blood!) to check for clotting tendency came back all OK. I'm currently waiting for a cardiac echo scan appointment.
I was initially prescribed daily 75mg Aspirin but this has been changed to 75mg Clopidogrel - when I asked how long I'd be on this for the rather brusk answer was "for life", which as someone who tries to avoid taking potions came as a bit of a shock.
The CAA have asked me to get my consultant to send a detailed report - hopefully this will be with them soon and then I'll have an outlook.
I'm very grateful for all the helpful comments, and for the PMs.
Rick
