Heart stents are replaced every few years

The stent does not need to be replaced regularly.

once the stent is placed, it will be tightly combined with the blood vessel wall and difficult to remove. Even if it is forcibly removed, it may cause damage to the blood vessel wall and even cause stenosis or occlusion. The stent is attached to the blood vessel wall to support and expand the blood vessel. Over time, the intima will gradually cover the stent surface, forming a new intima, so that the stent and the blood vessel wall will be integrated. Therefore, there is no saying that the stent should be replaced every few years.

It should be noted that if the patient has another blockage after surgery, it is necessary to reinstall the stent to ensure normal blood circulation.
