When should I have heart stent replaced?

Coronary stent: Coronary stents can not be "replaced" as such. However, they can be re-opened or restented if they renarrow , or restenose. The injury or trauma to the vessel wall during the initial stent placement results in a healing response with scar tissue growth. With current drug-eluting stents, scar tissue growth is inhibited and renarrowing occurs in only approximately 5%.

Metal=permanent: Metal stents are permanent. Your arterial walls eventually grow around the stent and incorporate it into the artery. There is no removing it.

No: It is a fairly commonly done procedure. Your cardiologist can advise you regarding the need and risks of procedure.
