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 The balloon is then deflated and the catheter is withdrawn.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

Faster, more potent antithrombotic drugs recommended for high-risk heart attack patients

The Cardiovascular Research Laboratory of the Bellvitge Biomedical Research Institute led by the cardiologist of the Bellvitge University Hospital Jos- Luis Ferreiro has conducted a study on the effect of antiplatelet drugs given to high risk patients suffering from acute myocardial infaction (heart attack) in the context of the Infarction Code.

Researchers to receive ASTRO Gold Medal for outstanding contributions to the field of radiation oncology

The American Society for Radiation Oncology (ASTRO) will award Amato J. Giaccia, PhD, Radhe Mohan, PhD, FASTRO, and Prabhakar Tripuraneni, MD, FASTRO, with the Society's highest honor—the ASTRO Gold Medal. The 2013 awardees will receive the ASTRO Gold Medal during the Awards Ceremony on Tuesday, September 24, at ASTRO's 55th Annual Meeting, September 22-25, 2013, at the Georgia World Congress Center in Atlanta.

Four lifestyle behaviors protect against coronary heart disease, say researchers

A large, multi-center study led by Johns Hopkins researchers has found a significant link between lifestyle factors and heart health, adding even more evidence in support of regular exercise, eating a Mediterranean-style diet, keeping a normal weight and, most importantly, not smoking.

New nanoparticle gene delivery method to prevent stenting procedure complications

Stent angioplasty saves lives, but there often are side effects and complications related to the procedure, such as arterial restenosis and thrombosis. In the June 2013 issue of The FASEB Journal, however, scientists report that they have discovered a new nanoparticle gene delivery method that may overcome current limitations of gene therapy vectors and prevent complications associated with the stenting procedure.

Omega-3 fatty acids may reduce inflammation associated with cardiovascular procedures

MD-Procedures like angioplasty, stenting and bypass surgery may save lives, but they also cause excessive inflammation and scarring, which ultimately can lead to permanent disability and even death.

European, US NSTE-ACS guidelines recommend bivalirudin alone in patients undergoing PCI

Results from a large observational study reported at EuroPCR 2013 today question whether bivalirudin is superior to heparin in the absence of GPIIb/IIIa blockade, showing similar 30-day mortality in patients with non-ST segment elevation acute coronary syndromes undergoing percutaneous coronary intervention.

Study analyzes potential usefulness of new treatment to reopen clogged arteries

Over the past few decades, scientists have developed many devices that can reopen clogged arteries, including angioplasty balloons and metallic stents.

Researchers examine new zinc-based bioabsorbable stents

In 2012, more than 3 million people had stents inserted in their coronary arteries. These tiny mesh tubes prop open blood vessels healing from procedures like a balloon angioplasty, which widens arteries blocked by clots or plaque deposits. After about six months, most damaged arteries are healed and stay open on their own. The stent, however, is there for a lifetime.

Lowering door-to-balloon times helps benefit STEMI patients, study finds

While all heart attacks have the potential to be deadly, one type is referred to as the "widow maker" because of its high risk of death. A ST segment elevation myocardial infarction is a severe type of heart attack that occurs when a blockage in a coronary artery causes heart muscle to die; without prompt treatment risk of fatality increases dramatically. Coronary angioplasty, or percutaneous coronary intervention, is the most common emergency treatment for STEMI.

New research on metallic implants could improve quality of life

Coronary stents have saved a lot of lives over the years, but there is a growing interest in what happens when a stent stays inside the body for too long.

Study: Patients who suffer STEMI heart attacks while hospitalized are 10 times more likely to die

If you suffer a heart attack while walking down the street and are taken to the hospital quickly, your chances of survival are very good. But if you have a heart attack while already in the hospital for something else, you are 10 times more likely to die.

Frozen balls of ice can safely kill cancerous tumors in lungs

Frozen balls of ice can safely kill cancerous tumors that have spread to the lungs, according to the first prospective multicenter trial of cryoablation. The results are being presented at the Society of Interventional Radiology's 38th Annual Scientific Meeting in New Orleans.

Scotland takes action to tackle relationship between deprivation and CVD

Deprivation represents the "elephant in the room" with regard to cardiovascular disease, and health care professionals have an important role to play in tackling the problem, delegates heard at a special plenary session opening the EuroHeart Care Congress in Glasgow, Scotland, 22 March to 23 March 2013.

Interventional endovascular therapy is safe but does not improve MS outcomes: Study

The first controlled clinical trial to test the safety and efficacy of interventional endovascular therapy on the symptoms and progression of multiple sclerosis has found that the intervention, sometimes called the "liberation treatment," which has attracted intense interest in the global MS community, does not improve patient outcomes. In a few cases, the treatment made symptoms worse.
