I have had 2 fitted (same artery 18 months apart) but due to healing around the stent they both failed
all this before the age of 40
the emidiate effect was great but over a period of 18 months it was just as bad as before
the advice I would give is keep active, eat healthy, regular health checks and listen to your doctor
don't think this is a life sentance You can still enjoy a beer or two but in moderation
