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.

New tool refines heart risk prediction

For about 10 years, the Framingham risk score has been used to estimate a person's chances of having a heart attack based on just six bits of information -- age, sex, total cholesterol, HDL cholesterol, smoking status, and systolic blood pressure.

Anti-reflux valve improves quality of life for cancer patients

An anti-reflux valve developed to help esophageal cancer patients also has been shown to help those with bile duct obstruction, according to Kulwinder S. Dua, M.D., a research physician at the Medical College of Wisconsin in Milwaukee.

Risk and outcome similar for bypass surgery, drug-eluting stents

Drug-eluting stent therapy and bypass surgery for coronary artery disease have about the same risk for a major cardiac event within 30 days after the procedures, researchers reported at the American Heart Association's 8th Annual Conference on Arteriosclerosis, Thrombosis and Vascular Biology.

Long-term safety of drug-eluting stents in off-label use

Research presented at the American College of Cardiology's Innovation in Intervention: i2 Summit 2007 in New Orleans, La, paints a picture of the "real world" use of drug-eluting stents and offers new insight into the connection between blood clotting, or thrombosis, in the stent - a dangerous complication - and adherence and responsiveness to anti-clotting medication.

Advances in clinical cardiology

Three studies being presented at the American College of Cardiology's Innovation in Intervention: i2 Summit 2007 in New Orleans, La., highlight the breadth of research propelling advances in clinical cardiology.

Trial of percutaneous coronary intervention added to optimal medical therapy in patients with stable coronary heart disease

Percutaneous coronary interventions (PCI) involve opening partially blocked arteries to improve blood flow to the heart. These procedures are performed more than 1 million times a year.

Adding estradiol to a polymer-free rapamycin-eluting stent is not associated with any measurable benefit

Patients admitted to the hospital with acute coronary syndromes (ACS) are often treated with a catheter-based procedure known as percutaneous coronary intervention (PCI), during which a stent is inserted into an occluded or narrowed coronary artery to restore blood flow to and from the heart.

Drug-eluting stents are disappointing in bypass grafts - sometimes!

While drug-eluting stents are effective in keeping open bypassed heart veins that aren?t too diffuse (filled with cholesterol plaque), a new study by cardiologists at Jefferson Medical College shows that they fare less well in keeping open bypassed veins with longer blockages.

Coronary procedure adds no benefit over 'optimal medical therapy' alone

Percutaneous coronary intervention plus optimal medical therapy does not improve outcomes in patients with coronary artery disease, compared with optimal medical therapy alone, according to study results presented at the 56th Annual Scientific Session of the American College of Cardiology in New Orleans, and published online in the New England Journal of Medicine.

Drug-eluting stent use in heart patients determined more by insurance type

If you want the best technology available to relieve blocked blood flow to the heart, the choice is a drug-eluting stent.

Plavix appears to be safe during and after heart bypass

Heart surgeons don't have to choose between taking a coronary-bypass patient off the popular anti-clotting drug clopidogrel (Plavix) after off-pump heart bypass surgery or having the patient bleed excessively in the days following surgery, according to a new study by researchers at Jefferson Medical College.

Medications plus lifestyle changes work as well as angioplasty to reduce deaths in stable heart-disease patients

Coronary revascularization with stenting or balloon angioplasty combined with optimal medical therapy is no more effective in preventing a heart attack, other major cardiovascular events or death in patients with stable heart disease, than optimal medical therapy alone, results of a new study conducted in 50 hospitals in the U.S. and Canada has shown.

House panel requests marketing documents from pharmaceutical companies regarding off-label drug promotion

The House Committee on Oversight and Government Reform has asked two stent manufacturers and three drug manufacturers to provide documents regarding the marketing of their products as part of the committee's investigation into the off-label use of drug-coated stents and prescription drugs, the Wall Street Journal reports.
