Heart stents do not need to be replaced after implantation.
Cardiac stent implantation is a rapid and definitive treatment for coronary artery disease. After the stent is implanted in the coronary artery, the endothelialization process will occur after 8~9 months, at this time the endothelium will cover the surface of the stent, which is equivalent to the stent and the blood vessel become one, so the stent does not need to be replaced.
Cardiac stent implantation is mainly used for patients with coronary artery disease. When patients have coronary artery disease, due to atherosclerosis of coronary arteries, the coronary arteries are narrowed, and the blood supply at the distal end of the narrowed arteries will be reduced, and cardiac stent implantation is to implant a metal stent in the narrowed location to relieve the narrowing.
After the implantation of a stent, you need to go to the hospital for regular follow-up and consult your doctor if you feel unwell.
