CORONARY STENTS

April 2, 2019

The National Pharmaceutical Pricing Authority (NPPA) has approved a hike in the price of coronary stents (bare metal stents as well as of Drug eluting/biodegradable stents). Last year, the Central government slashed rates of coronary stents by up to 85%.

Terminology:  

  • Coronary Artery Disease (CAD) happens when a waxy substance called plaque builds up on the inner walls of coronary arteries. This causes arteries to harden and narrow, decreasing blood flow to heart. 

  • Coronary stents are small, wire, mesh tubes that help widen a clogged artery and restore adequate blood flow to the heart. 

Working: 

  • During the procedure, cardiologist places the stent over a thin, long tube with a balloon tip called a catheter and insert it into an artery in groin or arm.

  • Once the stent reaches the clogged artery, doctor will inflate the balloon to expand the stent.

  • When the stent reaches the desired size to widen the clogged artery, doctor will deflate and remove the balloon.

  • The stent will stay in place permanently to help prop open the artery and decrease its chance of narrowing again.

  • Over time, the inner lining of the artery grows over the surface of the stent, making it a permanent part of artery.
