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.

Effective therapies to reduce perioperative morbidity and mortality remain elusive

Among intermediate- to high-risk patients undergoing coronary artery bypass graft surgery, administration of the agent acadesine to regulate adenosine (a naturally occurring chemical that dilates blood flow and can improve coronary blood flow and perfusion) did not reduce all-cause death, nonfatal stroke, or need for mechanical support for ventricular dysfunction, for approximately a month after surgery, according to a study in the July 11 issue of JAMA.

Special surface coating for stents to keep them in place

If a person's windpipe is constricted, an operation in which the surgeon inserts a stent to enlarge the trachea is often the only way to relieve their respiratory distress. But this grid-like implant can slip out of position, closing off the windpipe altogether. Researchers are working on a special surface coating for the stents to keep them in place.

Heart transplant patients who develop restenosis after receiving a stent have poor long-term survival

Heart transplant patients are notorious for developing an aggressive form of coronary artery disease that can often result in heart failure, death or the need for repeat transplantation. The condition can also have a negative impact on future cardiac procedures, such as stenting.

Simple exercise stress test still the most widely used medical test for coronary artery disease

Most people might assume that technology first developed in 1928 would be obsolete by now. But from air conditioned buildings to sliced bread, many inventions of that era are still essential to our lives today. That includes the exercise stress test, which is still the most widely used medical test for coronary artery disease.
