Patients with heart failure undergoing major non-cardiac surgical procedures are almost twice as likely to die as other patients, according to researchers at the Duke Clinical Research Institute (DCRI).
In their analysis of Medicare data, the researchers also found, to their surprise, that the outcomes after major non-cardiac surgery were similar in patients with coronary artery disease and those with no heart disease.
The findings about heart failure patients are significant, the researchers continued, because very little is known about how these patients fare when they undergo surgery. With the aging of the American population and the increase in the number of surgeries being performed, the researchers said it is crucial to understand why such a disparity in outcomes exist. "While the risks of coronary artery disease on patients undergoing surgery have always been considered in assessing risk, there is very little data on which to base guidelines for treating patients with heart failure," said Duke cardiologist Adrian Hernandez, M.D., lead author of a study whose results will be published Oct. 6, 2004, in the Journal of the American College of Cardiology.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

For the first time, scientists have precisely measured the effective electrical charge of a single molecule in solution. This fundamental insight of an SNSF Professor could also pave the way for future medical diagnostics.
Electrical charge is one of the key properties that allows molecules to interact. Life itself depends on this phenomenon: many biological processes involve...
At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
Scientists at Tokyo Institute of Technology (Tokyo Tech) and Tohoku University have developed high-quality GFO epitaxial films and systematically investigated their ferroelectric and ferromagnetic properties. They also demonstrated the room-temperature magnetocapacitance effects of these GFO thin films.
Multiferroic materials show magnetically driven ferroelectricity. They are attracting increasing attention because of their fascinating properties such as...
