Heart attack

Hi all,

I had a minor heart attack a week ago. I had 2 stents fitted, and everything is ok, my heart barely suffered any damage and is working on 59%. Apparently DVLA only needs 40% to let me continue HGV driving. Question is how long will they take to reissue my licence and how many hoops am I going to have to jump through before I get the OK. I know I have to do some kind of treadmill test. I’m also on various blood thinners, blood pressure tabs. If anyone out there has gone through similar I’d appreciate a heads up!

Many Thanks
