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 The balloon is then deflated and the catheter is withdrawn.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

Coronary artery stents that release medication appear more effective than traditional stents for patients with heart attack

A type of coronary artery stent that releases a medication appears to result in better outcomes than traditional stents for heart attack patients, according to a study in the May 4 issue of JAMA.

Trial to evaluate modern stent technologies over balloon angioplasty for peripheral arterial disease

The first patient undergoes treatment today in a new prospective randomised trial, called the SUPER Study, to compare stenting with balloon angioplasty in patients with superficial femoral artery (SFA) occlusions caused by peripheral artery disease (PAD).

Increased risk associated with combining carotid artery, coronary artery surgeries

Among patients undergoing evaluation for coronary artery bypass surgery, stroke neurologists are frequently consulted when the patient also has severe carotid artery stenosis (blockage of an artery that supplies blood to the brain).

Antibiotic treatment does not reduce risk of secondary cardiac events

Taking antibiotics weekly for one year does not reduce the risk of a heart attack or other cardiac event for patients with stable coronary artery disease, according to a study funded by the National Heart, Lung, and Blood Institute of the National Institutes of Health. It is published in the April 21, 2005, edition of the New England Journal of Medicine.

Women respond as well as men to treatment with drug-eluting stents

Despite the fact that symptomatic coronary disease afflicts men and women equally, only 33 percent of the 1.2 million interventional procedures conducted in the U.S. each year are done on women.

Women with heart attacks benefit from stenting

Female heart attack patients undergoing angioplasty have a higher risk of death than men, but stenting may improve their outcomes, according to a study reported in Circulation: Journal of the American Heart Association.

Modest triglyceride elevations linked to coronary artery disease risk

Even modest increases in blood levels of triglycerides, as well as a type of high cholesterol known as type III hyperlipidemia, are strongly associated with coronary artery disease in people with a family history of the disease, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

Gene therapy shows effect in heart patients

The first double-blind, placebo-controlled randomized trial of VEGF gene injections into the heart muscle of patients with coronary artery disease with the intention of spurring growth of new blood vessels showed significant effects on heart wall motion, although blood flow was not significantly better in treated patients, according to a new study in the April 5, 2005, issue of the Journal of the American College of Cardiology.

Study shows connection of varicose veins to chronic pelvic pain

Research presented today at the Society of Interventional Radiology's 30th Annual Scientific Meeting found that 16 percent of women with varicose veins in their legs simultaneously had ovarian varicose veins -- a common but often under-diagnosed cause of chronic pelvic pain.

Stent graft outperforms balloon angioplasty

A large, multi-center trial of 190 patients shows a new nonsurgical interventional radiology technique can benefit the more than 287,000 kidney failure patients undergoing dialysis in the United States each year.

Airway inflammation boosts infarction damage

Epidemiological studies show that the incidence of cardiovascular disease (CVD) complications are increased in long standing cases of asthma. Historically, the complications are often attributed to the chronic drug therapy used to treat asthma.

First patient to test new treatment for peripheral arterial disease

For several years, crippling leg pain has prevented Joan Erickson from walking more than a block. If she paused to rest, she could walk a little more, but not enough to continue playing golf, her favorite pastime.

Drug therapy may be comparable to invasive cardiac procedures for elderly patients with heart attack

Although the type and intensity of treatment for acute myocardial infarction (AMI) [heart attack] varies widely across the country, elderly patients who receive intensive medical treatment may have comparable survival as those who undergo invasive cardiac procedures (such as angioplasty and bypass surgery), according to a study in the March 16 issue of JAMA.

Blacks less likely to get expensive, newer heart treatments

Blacks who suffer the most common type of cardiac ischemia – non-ST-elevation acute coronary syndrome – are less likely than whites to receive expensive or newer evidence-based treatments, according to a report in a special disparities themed issue of Circulation: Journal of the American Heart Association.

Health care report cards may increase racial/ethnic disparities in bypass operations

Medical "report cards" intended to improve the quality of health care may sometimes reduce it for racial and ethnic minorities, according to a report in a special disparities themed issue of Circulation: Journal of the American Heart Association.

Blood clotting combo saves heart patients lives

Two studies presented Wednesday at the American College of Cardiology's annual scientific sessions in Orlando, Fla. have found that the clot-preventing drug Plavix when added to the treatment of people with severe heart attacks helps reopen their clogged arteries and saves lives.

Pet scanning could cut use of angiograms and bypass surgery, as well as patient costs

Using positron emission tomography (PET) scanning rather than other types of imaging as the first tool to diagnose heart-vessel blockages is more accurate, less invasive and saves dollars, a study by a University at Buffalo team has shown.

Study finds potential link to help find blocked heart arteries

A blood test in combination with a stress test can help better determine if someone is likely to have a blocked heart artery, according to a study by doctors at Providence Hospital in Southfield, Mich.
