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: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...

Im Focus: Water is not the same as water

Water molecules exist in two different forms with almost identical physical properties. For the first time, researchers have succeeded in separating the two forms to show that they can exhibit different chemical reactivities. These results were reported by researchers from the University of Basel and their colleagues in Hamburg in the scientific journal Nature Communications.

From a chemical perspective, water is a molecule in which a single oxygen atom is linked to two hydrogen atoms. It is less well known that water exists in two...
