Growth-factor therapy improves endothelial cell production and mobility in arterial disease
Using a growth factor to stimulate production of circulating endothelial progenitor cells increases the numbers of these vascular regenerative cells, improves mobility, and potentially could improve blood vessel function in patients with peripheral arterial disease (PAD).

Paclitaxel-releasing stent more effective than radiation therapy for preventing restenosis
Insertion of stents that release the drug paclitaxel to treat stenosis within an implanted bare-metal stent in a coronary artery reduces the risk of subsequent re-narrowing within the stent, when compared with treatment using intra-coronary radiation, according to a new study in the March 15 issue of JAMA.

Sirolimus-releasing stents more effective than VBT for treating restenosis within a stent
David R. Holmes, Jr., MD, of Mayo Clinic, Rochester, Minn., and colleagues with the SISR trial compared the use of vascular brachytherapy (VBT - intra-coronary radiation therapy) with implantation of the sirolimus-eluting stent for the treatment of restenosis occurring within a previously placed bare-metal stent, in a study appearing in the March 15 issue of JAMA.

Measuring artery repair cells could become new heart disease test
A more accurate method for measuring blood levels of specialized cells that circulate in the bloodstream and repair damage to the arterial lining has been discovered by Duke University Medical Center cardiologists.

Jefferson scientists find topical lubrication helps outcomes of coronary stent procedures
An emulsion of olive oil, egg yolk and glycerine might be just the recipe to keep heart patients away from the operating room and cardiac bypass surgery.

Lumbee Native Americans have higher cardiovascular risks
The Lumbees of south central North Carolina -- the second largest Native American tribe east of the Mississippi River -- have a significantly higher burden of cardiovascular risk factors than do similar non-Lumbees, according to a new analysis by Duke Clinical Research Institute researchers.

Age, sex, racial disparities in heart attack hospital transfer patterns
Older, female and minority patients rushed to community hospitals with acute heart attacks are less likely to be transferred to a larger hospital that offers procedures to immediately open clogged arteries, Duke University Medical Center cardiologists have found.

Studies highlight global risks of vascular disease, probe creative new treatments
Patients with a build-up of plaque in arteries in the heart, brain and leg face a high risk of major cardiovascular complications.

Researchers create conveyer belt for magnetic flux vortices in superconductors
Researchers at the University of Bath create a conveyer belt for magnetic flux vortices in superconductors.

Drug-eluting stents outperform radiation treatment for coronary restenosis in bare metal stents
In the first published trial of its kind, a multi-center clinical study has shown that drug-eluting stents outperform the current

Study puts drug-eluting stents to test in heart attack patients
Research presented today at the American College of Cardiology's inaugural Innovation in Intervention: i2 Summit 2006 in Atlanta, Ga., offers new insight into whether medicated stents can prevent late complications in patients with the most serious form of heart attack.

New test to detect rare proteins in blood
Researchers at the University of Pennsylvania School of Medicine have developed a paradigm-shifting method for detecting small amounts of proteins in the blood.
