Heart Stent Comparison

 Types

• Bare-Metal Stents (BMS):

These stents are made from stainless steel or cobalt chrome and offer a permanent, physical support to the artery wall.

They can reduce symptoms associated with heart disease but may cause scarring, which can lead to future blockage.

• Drug -Eluting Stents(DES) :

All stents have a risk that scar tissue will form and narrow the artery again. This scar tissue can block blood flow. However, drug-eluting stents are coated with drugs that prevent scar tissue from growing into the artery.

As the name suggests, these stents are coated with drugs that help to prevent scar tissue formation and future blockages of the artery.In addition, they also release medications over time, which help reduce inflammation and improve blood flow in the area.

DES has been linked to fewer long-term complications than BMS and tend to be recommended for more complex cases or those who have had previous stent placement.

·         Bio Absorbable Stent:

This is made of magnesium alloy. gets dissolved in 2 years. However, it is not suitable for elderly people with calcium.

 

Material of Stent

Stainless Steel, Nitinol (nickel–titanium) po, L605 cobalt chromium, MP35N cobalt chromium, Platinum chromium, Polymer, Bioabosroable Polymer

All these materials are strong but the thinner (<100UM) the stunt is the better it is.
