Luckygirl3 Have you not been given a discharge letter and told about follow-up arrangements? My GP was useless (I couldn't even get an appointment for five weeks) and I had to be transferred from Papworth, where the stent was fitted, to Addenbrooke's, but the hospital rang me within a couple of days and I was then booked in for an echo, cardiac rehab and a follow-up appointment. To be perfectly honest, I felt it was all too much and I was being hounded, but I can't complain that I wasn't followed up. I wasn't in any pain (and I'm no medic), but if you're still in pain, I think you should push to see a cardiologist.
PS. You'll need to speak to your GP for repeat prescriptions.
