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 The balloon is then deflated and the catheter is withdrawn.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

Quality of care for acute myocardial infarction in elderly patients with alcohol-related diagnoses

Older Americans with alcohol problems do not get worse treatment than their sober peers when they are hospitalized for a heart attack, according to new research on Medicare patients across the country.

Microfluidics chips for simplifying medical imaging biomarkers of disease

A collaboration between scientists at UCLA, Caltech, Stanford, Siemens and Fluidigm have developed a new technology using integrated microfluidics chips for simplifying, lowering the cost and diversifying the types of molecules used to image the biology of disease with the medical imaging technology, Positron Emission Tomography (PET).

Making angioplasty safer

When life-threatening problems occur during angioplasty procedures, doctors may perform emergency coronary artery bypass graft surgery, but data from the Mayo Clinic indicates that need to send patients to emergency surgery has dropped sharply, according to a new study in the Dec. 6, 2005, issue of the Journal of the American College of Cardiology.

Chronic stress induces rapid occlusion of angioplasty

Chronic stress can induce rapid blocking of arteries after a balloon angioplasty procedure, according to research performed in animal studies at Georgetown University Medical Center. Blocked coronary arteries after angioplasty affect 41 percent of patients who undergo the procedure and can lead to death.

Study of two drugs for angina treatment shows equal outcomes to patients

Researchers have found that the blood-thinning drug Lovenox works as well as a standard artery-clearing drug in patients with severe heart-related chest pain, but neither reduced the risk of death after a year of treatment.

American physicians may be too liberal in their use of blood transfusions

In an analysis of some 24,000 patient records, the researchers found that Americans rushed to the hospital with heart attack symptoms have significantly higher rates of bleeding and transfusions after treatment than similar patients throughout the world.

Lack of aggressive treatment for clogged leg blood vessels means missed heart attack prevention opportunity

Despite the fact that clogged arteries in the legs usually mean clogged arteries near the heart, doctors often fail to give heart-protecting drugs to people with severe leg blood vessel blockages, a new University of Michigan-led study finds.

African-American patients have worse quality of life after heart attacks

African-American patients have more chest pain, worse quality of life, and worse physical function than white patients one year after suffering acute coronary syndromes, such as heart attacks or unstable angina, according to a new study in the Nov. 15, 2005, issue of the Journal of the American College of Cardiology.

Shortness of breath can be a serious cardiac symptom

Now, researchers at Cedars-Sinai Medical Center have found that patients with shortness of breath can have a higher risk of dying from cardiac disease than patients without symptoms, and even than patients with typical cardiac pain.

Feeling puffed? could be a sign of serious heart problem

Most people know that chest pain can indicate the presence of heart disease, but less well known apparently is that shortness of breath can also be a symptom of serious cardiac problems

Cardiac regeneration using stem cells may heal hearts even years after heart attacks

Left ventricular function and exercise capacity increased, while the area of heart muscle damage shrank, in 18 patients given infusions of their own bone marrow stem cells up to eight years after a heart attack, according to a new study in the Nov. 1, 2005, issue of the Journal of the American College of Cardiology.

Two competing drug-eluting stents work equally well

After completing the most comprehensive U.S.-based study of its kind, Dr. Charles Simonton reported that the performance of two competing coronary stents was "virtually identical" in head-to-head comparisons.

Cell phones speed heart attack treatment

A Michigan hospital has cut in half the time it takes to begin life-saving treatment of heart attack patients by using cell phones to transmit electrocardiograms (ECGs) from the field

Real-world treatment of patients with acute coronary syndromes

A review of more than 56,000 cases of acute coronary syndromes reveals that older patients are less likely to receive treatment recommended by guidelines, even though they benefit as much or more than younger patients when the recommended treatment is provided, according to a new study in the Oct. 18, 2005, issue of the Journal of the American College of Cardiology.

Cost-effectiveness of potentially life-saving implantable cardioverter defibrillators (ICD) is an important public health issue

The use of implanted defibrillators that keep the heart beating in proper electrical rhythm to prevent cardiac arrest appears to be cost-effective for those patients who receive a significant mortality reduction, according to researchers from Duke Clinical Research Institute (DCRI), Stanford University and the VA Palo Alto Health Care System, Calif. They analyzed eight clinical trials of the devices to arrive at their conclusion.

Many people continue to smoke after life threatening event

An international survey published today (Thursday 6 October) in Europe's leading cardiology journal, European Heart Journal, reveals that fewer than half of the heart patients in the study who smoked quit after suffering their first coronary event, with one out of five continuing to smoke despite advice to stop.

Time-to-treatment is important to success of angioplasty treatment

An in-depth look at hospitals that reduced treatment delays highlights steps other hospitals could take to provide rapid angioplasty treatment to heart attack patients, according to a new study in the Oct. 4, 2005, issue of the Journal of the American College of Cardiology.

New treatment option for chronic sinusitis

Acclarent on Saturday unveiled their new treatment option for chronic sinusitis, the Balloon Sinuplasty procedure. Results from the initial safety and feasibility study of this unique, catheter-based treatment for chronic sinusitis were presented by William Bolger, MD, FACS.

HDL cholesterol helps prevent blocked arteries and heart attack

Cardiology experts at Johns Hopkins have issued interim guidelines for physicians on how best to treat low levels of HDL cholesterol, the so-called good cholesterol, which helps keep arteries clear from the buildup of LDL cholesterol, the so-called bad cholesterol.

Large scale study to see if angioplasty can be safely performed in small hospitals

Cardiologists at Johns Hopkins have launched a nationwide study of more than 16,000 patients to see if a potentially life-saving procedure called angioplasty can be safely performed in smaller, community hospitals, easing access to the therapy for patients. Researchers expect to enroll the first study patients in early fall 2005.
