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.

Taking ticagrelor alone better for patients with complex heart disease

Patients with complex heart disease who stopped taking aspirin three months after the insertion of one or more coronary stents and then took the anti-platelet medication ticagrelor alone for a year had fewer episodes of bleeding and no increase in heart attacks, stroke or other adverse events caused by blockages in the arteries, compared with patients who took both aspirin and ticagrelor over the same period.

10-year follow-up study shows safety, efficacy of stenting compared with bypass surgery

In a study with the longest follow-up to date of patients with a high-risk form of heart disease known as left main coronary artery disease (LMCAD), researchers found no significant differences in rates of death, heart attack or stroke between patients who were treated with a stent and those who underwent heart bypass surgery.

Treatment with ticagrelor alone reduces adverse events in patients with diabetes

Patients with diabetes who stopped taking aspirin three months after the insertion of a coronary stent and then took the anti-platelet medication ticagrelor alone for a year had fewer episodes of bleeding and no increase in heart attacks, stroke or other adverse events caused by blockages in the arteries, compared with patients who took both aspirin and ticagrelor for a year.

Trials find invasive surgery is no better than medication at reducing heart attack risk

Among stable ischemic heart disease patients, invasive procedures do not reduce heart attack or death risk more than medication.

Study shows feasibility of using a robot to treat brain aneurysms

Using a robot to treat brain aneurysms is feasible and could allow for improved precision when placing stents, coils and other devices, according to late breaking science presented today at the American Stroke Association's International Stroke Conference 2020.

Antiplatelet medication used to treat leg pain may prevent re-blockage of carotid artery stents

Adding cilostazol - an antiplatelet medication used to treat leg pain - tended to prevent re-blockage of carotid artery stents within two years, according to late-breaking science presented today at the American Stroke Association's International Stroke Conference 2020. The conference, Feb. 19-21 in Los Angeles, is a world premier meeting for researchers and clinicians dedicated to the science of stroke and brain health.

Intracranial stent appears to be safe and effective for reducing recurrent stroke risk

A brain stent appears safe and effective for reducing the risk of recurrent stroke in patients with cholesterol-clogged brain arteries, according to late breaking science presented today at the American Stroke Association's International Stroke Conference 2020.

VR helps cardiologist detect patient's injury and repair a broken heart

One night last December, in Gig Harbor, Washington, a restaurant co-worker told Brevin Cronk that his lips had turned blue. He made haste for a nearby emergency room, which measured his blood-oxygen at 77%, well shy of the 90% level that doctors consider "low."

Study highlights trends in hospitalization, outcomes among veterans with critical limb ischemia

Between 2005 and 2014, the number of veterans who were hospitalized, required amputation or died due to critical blockages in leg arteries declined, according to new research published today in Circulation: Cardiovascular Interventions, a journal of the American Heart Association.

Guideline-directed treatment is as effective as invasive procedures in patients with stable CAD

New study results found that guideline-directed medical treatment is as effective as invasive procedures, such as coronary stenting, at preventing heart attack, stroke, and death in patients with stable coronary artery disease.

New treatment could make passing kidney stones faster and less painful

Every year, more than half a million Americans visit the emergency room for kidney stone problems. In most cases, the stones eventually pass out of the body on their own, but the process can be excruciatingly painful.

UM trial to evaluate new stent as a treatment option for aneurysms

Robert M. Starke, M.D., M.Sc., an experienced neurosurgeon and researcher with the University of Miami Health System and Miller School of Medicine, has been conducting laboratory studies on a specialized stent designed to treat complex aneurysms in the blood vessels of the brain.

Treatment for coronary heart disease is just as good as stents or bypass

After 4 whole decades of thinking that invasive treatment (stenting or bypass surgery) for a local block in an artery due to cardiovascular (CV) disease could extend life and preserve heart health in patients who also had advanced kidney disease, the world just turned upside down.
