Stent News and Research

RSS

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.

Drug eluting stents provide better outcomes that bare metal stents in angioplasty

Patients receiving drug eluting stents (DES) - stents coated with medication to prevent narrowing of the artery - as part of an angioplasty had better outcomes one year later than patients with bare metal stents, according to a new study to be published in CMAJ.

Cardiac stent patients with diabetes may benefit from drug that counteracts the effects of leptin

The naturally high levels of leptin in diabetic patients may reduce the effectiveness of drug-eluting stents used to treat heart blockages, but using a chemical that differs from the one commonly used to coat stents could counteract this effect.

Nanomatrix stent coating designed to mimic natural endothelium

A nanomatrix for stent coating designed at the University of Alabama at Birmingham (UAB) mimics natural endothelium, the substance that lines blood vessels, and promises the potential to prevent post-operative tissue scaring along the blood vessel wall, greatly reducing the possibility of future thrombosis, or blockage at the stent site.
