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 The balloon is then deflated and the catheter is withdrawn.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

Caring for a family member with a serious heart ailment may increase your risk of cardiac disease

Researchers examined heart risk factors in family members of cardiac patients and found that those who provided all or most of a patient's care had higher levels of risk factors for heart disease than non-caregivers and those who reported higher caregiver strain after six months were more likely to be depressed than those who provided less or no care.

CT scan can harm kidneys, but cheap drug can help

As more and more Americans undergo CT scans and other medical imaging scans involving intense X-rays, a new study suggests that many of them should take a pre-scan drug that could protect their kidneys from damage.

Novel drug shows promise in limiting heart attack damage

A novel drug designed to lessen muscle damage from a heart attack has passed initial safety tests at the Duke Clinical Research Institute.

Review of psychosocial quit-smoking interventions for patients with coronary heart disease

Psychosocial interventions like counseling, telephone support and self-help materials can assist heart disease patients who are trying to give up cigarettes, but the most successful cessation treatments last a month or more, according to a new review of studies.

Patients at risk of adverse events within 3 months after stopping certain ACS therapy

Patients who receive the anti-platelet medication clopidogrel following an acute coronary syndrome (such as heart attack) appear to be at greater risk of a heart attack or death in the first 90 days after stopping clopidogrel treatment, according to a study in the February 6 issue of JAMA: The Journal of the American Medical Association.

FDA approves Endeavor Zotarolimus-eluting coronary stent

The U.S. Food and Drug Administration has approved the Endeavor Zotarolimus-Eluting Coronary Stent for use in treating patients with narrowed coronary arteries, the blood vessels supplying the heart.

Balloon catheter-based sinus surgery radiation exposure very low, safe

A new and increasingly popular type of minimally invasive sinus surgery exposes patients to only "very low" doses of radiation during the procedure, a level considered to be safe, according to a new study published in the February 2008 issue of the journal Otolaryngology - Head and Neck Surgery.

Researcher transplants stem cells to try to save patients' legs

A Northwestern University Feinberg School of Medicine researcher has launched the first U.S. trial in which a purified form of subjects' own adult stem cells was transplanted into their leg muscles with severely blocked arteries to try to grow new small blood vessels and restore circulation in their legs.

Heart and stroke death rates steadily decline; risks still too high

In an appropriate prelude to American Heart Month, which is just ahead in February, new mortality data from the Centers for Disease Control and Prevention (CDC) shows that, since 1999, coronary heart disease and stroke age-adjusted death rates are down by 25.8 percent and 24.4 percent, respectively.

Give yourself a natural bypass before you need a surgeon to perform a more painful and hazardous one?

When cholesterol-clogged plaque narrows an artery that feeds the heart, the body responds by trying to bulk up tiny blood vessels in the heart.

Study looks at prevalence of "false-positive" catheterization laboratory activation for patients with suspected STEMI

Physicians caring for patients suspected of having a heart attack may trigger "false-positive" activation of the cardiac catheterization laboratory based on test results suggestive of a heart attack, according to a study in the December 19 issue of JAMA: The Journal of the American Medical Association.

Adult stem cell heart attack study updated

Doctors are using patients' own bone marrow stem cells (progenitor cells) to treat the damage to cardiac muscle after a heart attack in a study at Emory University School of Medicine.

Computed tomography angiography accurate in detecting coronary artery disease

Computed tomography (CT) angiography is as accurate as an invasive angiogram in detecting coronary artery disease, according to the findings of the first two prospective multicenter 64-slice scanner trials presented today at the annual meeting of the Radiological Society of North America (RSNA).

Threat women face from vascular disease not widely understood

Though arterial vascular disease is widespread and often deadly among older American women, doctors too often fail to spot and treat it, according to a new report by a team of vascular surgeons from the Columbia University Medical Center and Weill Cornell Medical College campuses of NewYork-Presbyterian Hospital.

Skin injuries to patients can be avoided when radiation dose is monitored

Maximum radiation skin dose during coronary angioplasty can be accurately determined by monitoring the total entrance skin radiation dose as the patient is being examined and dividing that number in half according to a recent study conducted by researchers at Tohoku University in Sendai, Japan.

Drug-eluting stents versus bare-metal stents

Drug-eluting stents are just as safe and effective as traditional bare-metal stents when used in routine clinical practice, according to a new study by researchers at Rhode Island Hospital.

64-slice CT scans a good test for clogged arteries

A study by an international team of cardiac imaging specialists, led by researchers at Johns Hopkins, concludes that sophisticated computed tomography (CT) scans of the heart and its surrounding arteries are almost as reliable and accurate as more invasive procedures to check for blockages.

Living kidney donors show no increase in their risk of heart attacks

Living kidney donors show no increase in their risk of heart attacks or other cardiovascular events in the years after donation, according to the largest-ever study of the issue, being presented at the American Society of Nephrology's 40th Annual Meeting and Scientific Exposition in San Francisco.

Anticoagulant bivalirudin following angioplasty in heart attack patients reduces adverse events and bleeding

Late-breaking data presented at TCT 2007, the scientific symposium of the Cardiovascular Research Foundation (CRF), show that the use of the anticoagulant bivalirudin following angioplasty in heart attack patients reduces net adverse clinical events by 24 percent compared to the standard treatment, and significantly reduces major bleeding that occurs after angioplasty by 40 percent.
