Coronary artery stents, typically a metal framework, can be placed inside the artery to help keep it open. However, as the stent is a foreign object (not native to the body), it incites an immune response. This may cause scar tissue (cell proliferation) to rapidly grow over the stent and cause a neointimal hyperplasia.

For some high-risk cardiovascular patients with stents, the often-recommended practice of prolonged taking of aspirin might be ineffective, and in some cases, even harmful, a new study found.
When a stent is used, the stent tube mesh is initially collapsed onto the balloon component of the catheter. In this collapsed state, it is small enough to be passed though relatively narrow peripheral arteries and then inflated by the underlying balloon and pressed firmly against the diseased coronary artery wall.
As blood is pumped through the body, the valves within the veins prevent the blood from flowing backwards. After extensive, prolonged standing, these valves can become weak and eventually fail. When this happens, blood is no longer being prevented from flowing backward. Gravity will pull the blood back into an individual's legs, ankles and feet.
The FDA recently approved a heart stent made specifically for infants and young children, a device that could help kids born with certain congenital heart defects avoid a series of open heart ...

This is a common treatment for heart attacks and is also used in the prevention and treatment of strokes. Over 2 million people receive a stent each year for coronary artery disease alone.
