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 The balloon is then deflated and the catheter is withdrawn.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.

Drug developers should take a different approach to snake venom and heart medications

With the help of snake venom and sophisticated laboratory testing, scientists believe they've uncovered the reason why a group of new heart medications were doing some patients more harm than good.

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).

Smart gene therapy might effectively prevent the organ damage commonly suffered by heart attack victims

Early intervention with a novel kind of "smart gene therapy" might effectively prevent the organ damage commonly suffered by heart attack victims, suggests a new animal study by researchers at Brigham and Women's Hospital in Boston and Duke University Medical Center.

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

Left atrium neasurements may predict future for heart attack patients

Ultrasound measurements of the volume of the left atrium taken soon after a heart attack can help physicians predict a patient’s five-year mortality rate, according to a new study in the July 21, 2004 issue of the Journal of the American College of Cardiology.

Updated guidelines for treatment of blood cholesterol

The National Cholesterol Education Program (NCEP) has updated its guidelines for treatment of blood cholesterol, suggesting that people at risk for heart attack and stroke would benefit from more intensive cholesterol-lowering therapies.

Evidence is emerging that adult stem cells from bone marrow have therapeutic potential for restoring cardiac cells

Results of a randomised trial in this week’s issue of THE LANCET suggest that the transfer of adult stem cells derived from bone marrow could improve cardiac functioning after heart attack.

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.

Innovative type of brain scan can determine where blockages of blood to the brain lie

It's a no-brainer that the brain needs a constant supply of blood to keep it going. But some medical conditions can block or reduce that life-giving flow. Whether it's a stroke, a clogged artery or a brain tumor, any situation where blood can't get to the whole brain can lead to death or permanent disability.

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.

Financially burdened patients more likely to die after coronary revascularization

Heart patients who had angioplasty or bypass surgery and felt burdened by medical costs were more than twice as likely to die within a year of their procedure as patients who didn’t have trouble paying for healthcare, according to a study presented today at the American Heart Association’s 5th annual Scientific Forum on Quality of Care and Outcomes Research in Cardiovascular Disease and Stroke.

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.

Nonalcoholic beer impart cardiovascular benefits without the negative effects of alcohol

New findings published in the May issue of Alcoholism: Clinical & Experimental Research indicate that nonalcoholic beer may also be able to impart cardiovascular benefits without the negative effects of alcohol, by inhibiting blood coagulation and platelet activation.

New stent appears safe and effective for preventing arteries from reclosing in coronary heart disease patients

A new stent appears safe and effective for preventing arteries from reclosing in coronary heart disease patients, based on one-year results of the first human trial using this stent reported in today’s rapid access issue of Circulation: Journal of the American Heart Association.
