Drug-coated stents are safe and effective at preventing death, heart attack or repeat procedures in "real world" patients who are often sicker or older than those selected for clinical trials, according to a study in todays rapid issue of Circulation: Journal of the American Heart Association.
The drug-coated stents were more effective than uncoated stents, just as they had been in clinical trials, said lead investigator Patrick W. Serruys, M.D., Ph.D., professor of cardiology at Erasmus Medical Center in Rotterdam, the Netherlands.
This "real world" research is important because patients in clinical trials of drug-coated stents "were a very select group, whereas this registry is an attempt to look at in an unselected population," Serruys said. "Sixty-eight percent of the patients in this study did not meet the selection criteria for the clinical trials."

A research team led by physicists at the Technical University of Munich (TUM) has developed molecular nanoswitches that can be toggled between two structurally different states using an applied voltage. They can serve as the basis for a pioneering class of devices that could replace silicon-based components with organic molecules.
The development of new electronic technologies drives the incessant reduction of functional component sizes. In the context of an international collaborative...
At the LASYS 2018, from June 5th to 7th, the Laser Zentrum Hannover e.V. (LZH) will be showcasing processes for the laser material processing of tomorrow in hall 4 at stand 4E75. With blown bomb shells the LZH will present first results of a research project on civil security.
At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...
