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.

Rosiglitazone helps boost the effectiveness of a treatment for opening clogged arteries

Rosiglitazone, a drug taken to help improve blood sugar levels, also helps boost the effectiveness of a treatment for opening clogged arteries, according to a study in the November issue of Diabetes Care.

Early reports of thrombosis after insertion of drug-eluting stent

Authors of a research letter in this week’s issue of THE LANCET highlight how the use of drug-eluting stents (DES) may carry a risk of subsequent thrombosis if stenting is accompanied by a withdrawal of antiplatelet therapy.

Study raises important questions about the use of drugs that promote or prevent angiogenesis

Dartmouth Medical School cardiology researchers have discovered a new mechanism for what drives the growth of muscle tissue in the lining of injured heart vessels that can eventually lead to blockage.

FDA approval for small vessel cobalt chromium coronary stent

Guidant Corporation has announced U.S. Food and Drug Administration (FDA) approval of the company’s newest stent system designed to treat coronary artery disease in small vessels in patients with abrupt or threatened abrupt closure.

Moderate alcohol consumption cuts rate of further narrowing after heart surgery

New German research from Heidelberg University suggests that moderate drinking cuts the rate of further narrowing after surgery to open blocked arteries. The findings are published in the current issue of Heart.

FDA approves stent that treats blockages in the main blood vessel leading to the brain

The U.S. Food and Drug Administration has approved a stent for use in opening blocked arteries in the neck. The new stent is intended to prevent stroke by treating blockages in the carotid artery, the main blood vessel leading to the brain.

Less invasive procedure to repair aortic aneurysm could reduce death by two-thirds

Early results of a UK study published online by THE LANCET suggest that a surgical procedure to repair aortic aneurysm that is less invasive than conventional open surgery could reduce death within a month of surgery by around two-thirds.

Drug-eluting stents (DES), increasingly used in coronary angioplasty, have benefits over bare-metal stents

A pooled analysis of 11 previously published trials provides evidence that drug-eluting stents (DES)—increasingly used in coronary angioplasty—have benefits over bare-metal stents (BMS) by reducing the need for later revascularisation and reducing the risk of cardiac events

FDA has granted orphan drug designation to Myogen's ambrisentan, for the treatment of pulmonary arterial hypertension

Myogen has announced that the United States Food and Drug Administration has granted orphan drug designation to ambrisentan for the treatment of pulmonary arterial hypertension (PAH).

Radial artery appears to be a safe alternative to femoral artery for catheter procedures

Instead of threading catheters from the femoral artery in the groin, cardiologists can safely use the radial artery in the arm to gain access to coronary arteries for angioplasty, stent placement, and other procedures

Anticoagulant therapy with enoxaparin is an effective alternative to heparin therapy for patients with acute coronary syndromes

Two new major studies suggest that anticoagulant therapy with enoxaparin is an effective alternative to heparin therapy for patients with acute coronary syndromes (ACS)

Method of producing exact models of skull defects which enable technicians to create exactly matching titanium plates

The work of a student at the University of Ulster has had a direct effect on the treatment of patients requiring head and facial surgery.

Repeating balloon angioplasty and/or stenting procedures in elderly patients add more than $700 million a year to Medicare expenses

Repeating balloon angioplasty and/or stenting procedures to open narrowed arteries in elderly patients may add more than $700 million a year to Medicare expenses, according to a report in today’s rapid access issue of Circulation: Journal of the American Heart Association.

Stents designed with thinner and fewer linkages may be the basis of a new generation of stents

An investigation of how blood flows through stents after opening clogged arteries has led a team of researchers at the Medical College of Wisconsin Cardiovascular Center in Milwaukee to suggest that stents designed with thinner and fewer linkages may be the basis of a new generation of stents.

Results from study of Rituxan in rheumatoid arthritis show promise

Genentech, Inc., Biogen Idec and Roche have announced that the New England Journal of Medicine published the results of a Phase IIa study showing that two doses of Rituxan® (Rituximab), administered two weeks apart, improved symptoms in patients with moderate-to-severe rheumatoid arthritis (RA) for up to 48 weeks when combined with methotrexate (MTX), compared to MTX alone.

Stent methodologies for treating occluded arteries

Branch points in the arteries are a common area of atherosclerotic disease, resulting in the occlusion of both branches. These branch points can generally be defined as a main branch and a side branch, and, in treating the disease, the question of what is the optimal course of action, opening the main branch, the side branch, or both, remains uncertain.

Atkins high-fat-low-carbohydrate diet may have caused severe heart disease

A Florida businessman filed suit today against Atkins Nutritionals, Inc., and the Estate of Dr. Robert C. Atkins, claiming that the late diet author’s controversial high-fat, low-carbohydrate regimen caused severe heart disease, necessitating angioplasty and a stent. He is seeking a court injunction banning Atkins Nutritionals from marketing its products without a warning of potential health risks and asks for compensatory damages.

In one unusual circumstance smoking may actually be good for you

An Austrian study has found that smoking cigarettes, a habit that contributes to the development of peripheral artery disease-actually helps arteries stay open following a procedure to repair clogged blood vessels in the legs. The study found that habitual to heavy smokers who continued to smoke after angioplasty had a lower rate of restenosis, or re-narrowing of the arteries, than nonsmokers.

Higher volume may not guarantee higher quality angioplasty and stenting

"Practice makes perfect" seems logical, but how much practice remains uncertain, and current health care quality guidelines may be set too high. It may be time to reexamine the standard recommending hospitals perform at least 400 angioplasty and stent procedures per year, according to a new study in the May 19, 2004 issue of the Journal of the American College of Cardiology.
