Mayo Clinic researchers document safer treatment for atrial fibrillation

30.09.2002


Mayo Clinic researchers report that the risk of stroke that sometimes results from a common treatment for atrial fibrillation can be minimized when the patient takes anticoagulation medication prior to the procedure.



The researchers report on the largest single medical center experience regarding safety of elective direct current (DC) cardioversion of atrial fibrillation. DC cardioversion is the electronic restoration of the heart’s normal rhythm.

Atrial fibrillation affects more than 2.5 million people in the United States. It is characterized by an irregular and rapid beating of the heart’s atrial chambers and results when the normal electrical conduction system of the atria is not functioning properly. It is estimated that atrial fibrillation is responsible for more than 70,000 strokes each year in the United States. The prevalence of atrial fibrillation increases with age.


The researchers found that the rate of stroke or other embolic happenings -- clots or blockages of the blood vessels -- occurring in a patient after cardioversion was less than 1 percent. In the study, 834 successful cardioversions were performed in 717 patients from 1990 through 1994. Researchers said that use of adequate anticoagulation medication prior to the procedure reduced the risk of thromboembolism.

Mayo Clinic researchers involved in the study were Federico Gentile, M.D.; Bijoy Khanderia, M.D.; James Seward, M.D.; Christine Lohse, BSc; Win-Kuang Shen, M.D.; Kent Bailey, Ph.D.; Samantha Montgomery, MSc; Belli Burger, BSc and A. Jamil Tajik, M.D. Abdou Elhendy, M.D., Ph.D. is now with the University of Nebraska, Omaha.

Warren Manning, M.D., and Peter Zimetbaum, M.D., of Beth Israel Deaconess Medical Center in Boston, write in an accompanying editorial that clinicians must assess the individual patient to determine the benefits of cardioversion.

"If the decision favors cardioversion, (the researchers) have provided further proof of the efficacy of three to four weeks of warfarin anticoagulation before cardioversion," the editorialists write about the current approach to treatment.

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....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
