Angioplasty News and Research

RSS

In angioplasty procedures, a balloon is fed through a catheter and used to prop open an artery that has become narrowed or blocked. In cases where stenting is appropriate, a stent mounted on a balloon is inserted and inflation of the balloon expands the stent against the blocked artery wall to hold the vessel open. The balloon is then deflated and the catheter is withdrawn. Stent treatment of arteries holds them open and improves blood flow to the heart. In cases where post-dilatation is needed, a high-pressure balloon is inflated inside a stent to help better place the stent against the vessel wall.

System helps physicians prevent radiation-induced skin injuries to patients

The threading of slender catheters and stents through arteries to deliver treatments to the heart, the brain and elsewhere in the body has produced nothing short of a medical revolution.

Startling new blood pressure findings - atherosclerosis slowed

A new study led by The Cleveland Clinic shows that giving blood pressure lowering medication to heart disease patients with a “normal” blood pressure dramatically reduces risk of adverse cardiac events and slows disease progression.

Sirolimus drug-coated stent causes less inflammation than bare metal stents

In the treatment of coronary artery disease, a sirolimus drug-coated stent causes less inflammation than bare metal stents, according to preliminary research presented at the American Heart Association annual meeting by Loyola University Health System, Maywood, Ill.

A new magnetic navigation system shows promise for use during percutaneous coronary interventions

The magnetic-assisted intervention is being introduced in the United States and Europe, with fewer than 15 systems installed at institutions worldwide. Developed by Stereotaxis, Inc., a St. Louis firm, the system was approved by the U.S. Food and Drug Administration in 2003.

ACE inhibitors not needed for many heart disease patients

Many heart disease patients who are already receiving state-of-the-art therapy do not benefit from additional treatment with angiotensin converting enzyme (ACE) inhibitors, according to results of a new study funded by the National Heart, Lung, and Blood Institute (NHLBI).

Coronary stents have no impact on mortality over the long term

While the placement of stents in newly reopened coronary arteries has been shown to reduce the need for repeat angioplasty procedures, researchers from the Duke Clinical Research Institute have found that stents have no impact on mortality over the long term.

Landmark case challenges safety of Atkins diet

West Palm Beach County Court Judge Susan Lubitz ruled today that the landmark lawsuit filed by former Atkins dieter and Florida businessman Jody Gorran will go forward.

First hearing in the landmark lawsuit against Atkins Nutritionals

The plaintiff, 53-year-old Jody Gorran, will argue that the Atkins corporation should be held liable for the life-threatening artery blockage he suffered after more than two years on the diet. Gorran filed suit against Atkins Nutritionals on May 26 in Palm Beach County Courthouse.

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.

Researchers have developed a novel drug-antidote pair

In a discovery that could give physicians more control over the actions of medications, researchers at Duke University Medical Center have developed a novel drug pair – a potent anti-coagulant with a matched "antidote."

Biomarker called cystatin C predicts which people are less likely to survive a heart attack

A biomarker called cystatin C, which measures kidney function, predicts which people are less likely to survive a heart attack, according to research published in Circulation: Journal of the American Heart Association.

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.

Coronary angioplasty within 24 hours of medical therapy could improve the outcome for heart-attack patients

Results of a randomised trial in this week’s issue of THE LANCET suggest that a more aggressive approach involving coronary angioplasty soon after anticlotting medical therapy is safe and could offer a better prognosis than more conservative treatment for patients who have had heart attack.

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.

Spouses' emotions can effect psychological recovery after a heart attack or angioplasty

Psychological recovery after a heart attack or angioplasty may be delayed if patients’ spouses feel even more anxious or depressed than their ill partners, researchers say.

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.

Cardiac rehabilitation improves survival rates by 50%

The study of 1,821 patients from Olmsted County, Minn., who had heart attacks between 1982 and 1998 and survived to go home from the hospital, found that nearly half (48 percent) of the deaths within three years of hospital discharge were attributable to not participating in cardiac rehabilitation.

Surgery for angina in the elderly provides long-term mortality

Elderly people who undergo surgery or angioplasty to treat chest pain fare just as well long-term as those treated with medication, researchers report in Circulation: Journal of the American Heart Association.
