How to reduce the risk of coronary re-stenosis after stenting

After 12 months, if the wound healing process forms keloid scars that cause a narrowing of the coronary lumen by more than 50% called re-stenosis in the stent.

If endothelial cells only grow to cover the stent with a thin layer, causing a narrowing < 50% of the lumen of the vessels called non-re-narrowing.

The person can cohabit with the stent for life, without replacing the stent with a new one.

The stent frame is very thin, which does not affect the subsequent magnetic resonance imaging of the patient.

I put a coronary stent 4 months ago. How long do stents last, is there a risk of re-narrowing? how to minimize the risk?

Answer:

From 1989-2000, companies invented only drug-coated stents, the rate of re-stenosis in the stent at the time of 12 months after stenting was about 20-40%.

Since 2000, with the advancement of science, there are many types of drug-coated stents, anti-re-narrowing of many companies, the re-narrowing rate is reduced to 5-10%.
