A stent is a small mesh tube that’s used to treat narrowed or weakened arteries in the body.

You may have a stent placed in an artery as part of a procedure called angioplasty (AN-jee-oh-plas-tee). Angioplasty can restore blood flow through narrowed or blocked arteries. Stents help prevent arteries from becoming narrowed or blocked again in the months or years after treatment with angioplasty. You may also have a stent placed in a weakened artery to improve blood flow and to help prevent the artery from bursting.

Stents are usually made of metal mesh, but sometimes they’re made of fabric. Fabric stents, also called stent grafts, are used in larger arteries. Some stents are coated with medicines that are slowly and continuously released into the artery. These medicines help prevent the artery from becoming blocked again.

Chances of surviving a heart attack are much lower in UK than Sweden, shows study

The chance of surviving a heart attack is far lower in the UK than Sweden, according to a major new study published in The Lancet. The startling findings suggest that more than 11000 lives could have been saved over the past 7 years had UK patients experienced the same care as their Swedish counterparts. [More]

Inflating balloon inside artery after stent placement increases patients' risk of serious complications

Johns Hopkins surgeons say skipping one commonly taken step during a routine procedure to insert a wire mesh stent into a partially blocked carotid artery appears to prevent patients from developing dangerously low blood pressure, an extremely slow heart rate or even a stroke or heart attack. [More]
