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.

Cardiac stents may cause tingling in some patients

Coronary stents are commonly used to open blocked arteries of patients with coronary artery disease.

Bypass surgery more likely than angioplasty to relieve coronary artery disease pain

Patients with mid-range coronary artery disease are more likely to get relief from painful angina and less likely to have repeat procedures if they get bypass surgery rather than balloon angioplasty with or without a stent, according to a new report by the Agency for Healthcare Research and Quality, part of the U.S. Department of Health and Human Services.

Little difference in risk rates for angioplasty, bypass procedures

Patients with heart disease who undergo coronary angioplasty have an equivalent risk of death and heart attack as patients who undergo coronary bypass surgery, according to Stanford University School of Medicine researchers.

Mortality rates 71 percent lower at top-rated hospitals

Patients have on average a 71 percent lower chance of dying at the nation's top-rated hospitals compared with the lowest-rated hospitals across 18 procedures and conditions analyzed in the tenth annual HealthGrades Hospital Quality in America Study, issued today by HealthGrades, the healthcare ratings company.

Anticlotting drug found to be safe in sickle cell patients

An intravenous "blood thinner" widely used in patients with acute coronary syndromes and during coronary artery stent placement appears to be safe in patients with sickle cell disease and may have beneficial anti-inflammatory effects, a small study at the University of North Carolina at Chapel Hill School of Medicine has found.

Reversal of blood flow to the brain may help protect against stroke during carotid stenting

Surgeons at the Methodist DeBakey Heart Center in Houston have begun a new trial that will seek to protect patients from stroke by reversing blood flow in the brain during carotid stenting.

Non-invasive imaging test could help prevent heart attacks

Kathy Brown says she always thought that heart disease was for those who smoked cigarettes, drank, ate a lot of red meat, and who were overweight.

New guidelines for cardiac testing and treatments

People with heart disease should take special precautions before undergoing any kind of surgery, even noncardiac surgery, to reduce their risk of a cardiac event, according to new joint guidelines from the American College of Cardiology and the American Heart Association.

Rehabilitation significantly underused after heart attack and bypass surgery

Despite strong evidence that cardiac rehabilitation reduces disability and prolongs life, fewer than one in five people receive rehabilitation services after a heart attack or coronary bypass surgery, according to a Brandeis study in Circulation: Journal of the American Heart Association.

New synthetic version of the drug heparin

Researchers at the University of North Carolina at Chapel Hill have patented a synthetic version of the drug heparin, called Recomparin, that is less complex chemically and should be easier to produce than previous forms.

New minimally-invasive coated vascular stent graft in use at Methodist DeBakey Heart Center

Surgeons at the Methodist DeBakey Heart Center in Houston were among the first in the U.S. to implant a new, less-invasive stent graft designed to reduce the risk of blood clots in patients treated for peripheral arterial disease (PAD), which affects as many as 12 million Americans over the age of 50.

John Cheatham receives prestigious award for work on congenital heart disease

The Pediatric Interventional Cardiac Symposium (PICS) & Adult Interventional Cardiac Symposium (AICS) Lifetime Achievement Award for 2007 was recently presented to John P. Cheatham, MD, Co-Director of The Heart Center at Columbus Children's Hospital and Professor of Pediatrics & Internal Medicine at The Ohio State University College of Medicine.

Drug eluting stents should be used with caution in acute myocardial infarction

Drug-eluting stents are extremely effective devices to prevent restenosis following angioplasty. Yet, since last year, there is some debate and persistent uncertainty regarding the long term safety of these devices. Specifically, there is concern that some of these stents may occlude abruptly more than 1 year after placement, due to "late stent thrombosis".

OPTIMIST: The Outcome of PCI for stent-ThrombosIs MultIcentre STudy

Stent thrombosis is a recognized complication occurring in 1-2% of patients with coronary artery disease treated by percutaneous coronary intervention (PCI) with stent implantation. Its occurrence is expected to increase with the number of stent implantation procedures done worldwide. Moreover, stent thrombosis is a hot topic in the cardiology community.

The goals of platelet inhibition in acute coronary syndromes

Platelet activation and aggregation play important roles in the pathogenesis of cardiac ischemic events after either spontaneous plaque disruption in acute coronary syndromes or mechanical disruption of coronary artery plaques caused by percutaneous coronary intervention (PCI), which could be considered an artificially induced acute coronary syndrome.
