New Angioplasty Procedure Proving More Effective

16.11.2006
Over the last several years angioplasty has exceeded coronary bypass surgery as the preferred way to treat coronary artery disease. The stents (narrow tubes inserted into the artery to facilitate blood flow) commonly used in the procedure are less invasive than open-heart surgery and offer greater convenience to the patient and the ability to perform more complex procedures.

However, they are also more likely to lead to restenosis, a recurrence of artery clogging. According to findings in Journal of Cardiac Surgery, newly developed drug-eluting stents (DES) that release a drug directly to the injured blood vessels are less likely to lead to restenosis than traditionally used bare-metal stents (BMS). Controversy exists regarding the role of stents in the treatment of complex multi-vessel coronary artery disease and the potential for late complications.

While studies have found that DES procedures limit restenosis and, consequently, improve quality of life, the associated medical care would cost patients an average of $900 more during the two-year period following the procedure than with BMS. This cost is expected to decrease within five years, however, rendering DES cost-neutral or cost-saving when compared to BMS.

Despite the positive outcomes associated with DES, the procedure should not be viewed as a replacement for surgery. DES have proven to be safe and effective over the short and medium term, but long term effects have not been sufficiently explored.

“The impact of DES has greatly reduced the volume of coronary artery surgeries, however, the two must be regarded as complementary and not competitive strategies,” says Dr. Shahzad G. Raja, author of the study.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
