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 The balloon is then deflated and the catheter is withdrawn.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

Free, online self-assessment quiz helps assess health and lifestyle risks for PAD

As recent medical studies continue to highlight the seriousness of peripheral arterial disease (or PAD) and its association with heart attack, stroke and early mortality, the Society of Interventional Radiology Foundation recommends that older Americans, smokers and diabetics take its free, online self-assessment quiz.

Society of Interventional Radiology's resources emphasize on PAD

The Society of Interventional Radiology offers numerous resources just in time for September's national peripheral arterial disease (or PAD) awareness month. As recent medical studies continue to highlight the seriousness of PAD, these resources are welcome additions to libraries for interventional radiologists and primary care physicians who want to learn more about minimally invasive treatments for this disease that affects an estimated 10 million people in the United States.

Pre-hospitalization strategies will bring down mortality rate of patients with heart disorders

Mortality rate following a heart attack has fallen by more than 50% in Europe over the past 25 years. However, because only minor advances in the medical treatment of AMI are expected over the next decade, it is through organisational changes in the pre-hospital phase that mortality rate will continue this decline to below 5%.

Primary angioplasty procedures vary in European countries

Primary angioplasty (with stent implantation) is the most effective therapy for acute myocardial infarction (AMI), but it is not available to many patients, even though most European countries have sufficient resources (ie, catheterisation laboratories) for its wider use.

Immediate catheterization not always better for ACS patients

For some patients with acute coronary syndromes, the strategy of immediate intervention at a medical center does not appear to result in differences in outcomes in comparison with an intervention performed the next working day, according to a study in the September 2 issue of JAMA.

Acute myocardial infarction: One of the leading causes of death in the Western world

Acute myocardial infarction (AMI) remains one of the leading causes of death in the Western world, with prevalence predicted to increase dramatically in developing countries, especially India and China.

Ochsner Medical Center selected to participate as an FDA investigative site in the PARTNER clinical trial

On Tuesday, August 11, 2009, an 82-year old New Orleans resident with severe aortic stenosis successfully had a heart valve replaced at Ochsner Medical Center using the same technique as angioplasty, a far cry from the traditional open heart procedure. Patients who are considered high-risk or non-operable for conventional open heart valve surgery now have a potential new research option available regionally only through The John Ochsner Heart & Vascular Institute.

University of Maryland researchers perform a genome-wide association study of ADP-stimulated platelet aggregation

Patients with a certain genetic variation who received the antiplatelet drug clopidogrel had a decreased platelet response to treatment and among those who had percutaneous coronary intervention (procedures such as balloon angioplasty or stent placement used to open narrowed coronary arteries) had an increased risk of having a cardiovascular event in the following year than patients who did not have this variant, according to a study in the August 26 issue of JAMA.

First patient enrolled for IDEV Technologies' SUPERB clinical trial

IDEV(R) Technologies, Incorporated, (IDEV) an emerging leader in the development and marketing of minimally invasive medical technologies, today announced that the first patient was enrolled in the Company's FDA-approved multi-center clinical trial of its self-expanding SUPERA(R) stent, a novel stent platform designed for the treatment of biliary and peripheral artery disease (PAD) in the superficial femoral artery (SFA).

Cardiovascular Systems' revenues in fourth-quarter of 2009 increases to $15.7 million

Cardiovascular Systems, Inc. (CSI), a medical device company developing and commercializing innovative interventional treatment systems for vascular disease, today reported financial results for its fourth quarter and fiscal year ended June 30, 2009.

Medical imaging: The good, the bad and the ugly

In the political minefield of healthcare reform, medical imaging has emerged as a microcosm of this contentious debate. Congress has been charged with a high stakes, high wire balancing act: to create a bill preserving quality and access while trimming unethical and unnecessary spending. Medical imaging represents such a challenge, with its undeniable benefits tainted by inappropriate use.

Radiation exposure during interventional procedures a concern for some developing countries

Many facilities in these countries lack the concept of patient dose estimation and dose management, putting patients at a higher risk of developing complications due to overexposure from radiation during interventional procedures, according to a study performed by the International Atomic Energy Agency in Vienna, Austria.

New drug promises to reduce damage from a heart attack

Research into a new drug by Australian heart experts has found that it can dramatically reduce heart muscle damage after a heart attack.

New drug may reduce heart attack damage

A novel drug that targets a master disease-causing gene can dramatically reduce heart muscle damage after a heart attack and may lead to significantly improved patient outcomes, researchers at the University of New South Wales (UNSW) have shown.

FDA approves Effient (prasugrel) for heart attack in angioplasty patients

The U.S. Food and Drug Administration has approved the blood-thinning drug Effient tablets (prasugrel) to reduce the risk of blood clots from forming in patients who undergo angioplasty, a common procedure to unblock a clogged coronary artery.

Diabetes with coronary disease: A moving target amid evolving therapies

In an editorial in the current issue of the New England Journal of Medicine (NEJM), William E. Boden, M.D., professor of medicine and preventive medicine at the University at Buffalo, recommends that the results of the BARI-2D Trial published in that edition must be interpreted with "considerable caution."

Drug-eluting stents more effective than bare-metal stents in heart attack patients

NewYork-Presbyterian Hospital and Columbia University Medical Center, together with the Cardiovascular Research Foundation (CRF), announced that its landmark study comparing the safety and efficacy of drug-eluting stents and bare-metal stents was published in the May 7 New England Journal of Medicine.

FHL2 protein regulates blood vessel maintenance

In a study led by Akiko Hata, PhD, of Tufts University School of Medicine, researchers have shown that a protein expressed in the heart, FHL2, inhibits the genes necessary for the quiescence of vascular smooth muscle cells (vSMCs), which line blood vessels.
