What is the gold standard indicator that this needs to happen? Is it a scan or x-ray? The person has had this done at lwast twice, and once one year ago. Where can I look to get a summary about stents. Any information would be appreciated. Thank you.

Hi: Bare-metal or drug-eluting stents are not replaced, as this type of implant lasts in the coronary artery for the life of the patient. After implanted, the stent is gradually incorporated (new tissue grows over and through the struts, drug-eluting somewhat delays this, hence possible blood clot problems) into the vessel wall, essentially becoming a permanent part of it. The drug contained on a drug-eluting stent, which is gradually released, and the polymer coating that gradually releases it, only lasts for a limited period of time, as is designed to, is intended to do so. ☞Sometimes though, a problem can occur at the stented site, such as restenosis (renarrowing, in some cases, even with drug-eluting stents), or new or accelerated atherosclerotic plaque buildup, requiring another angioplasty and possible re-stenting or "stent sandwich" (placing a stent within a stent). b "What is the gold standard" While the "gold standard" for determining if the patient really needs another stent, or if there is a problem with an existing stent, is invasive X-ray angiography (angiogram, heart catheterization), on an individualized case-by-case basis, non-invasive Cardiac CT/CT angiography may/can be considered appropriate instead. b "Where can I look to get a summary about stents?" Some really good general info can be found at - HeartSite b Stents www.heartsite.com/html/stent.html b Drug-coated stents www.heartsite.com/html/drug_stent.html Coronary stents are only a Band-aid or spot-treatment, as it doesn't address the disease processes and what drives the progression. Best of luck to the person you speak of.
