Patients who undergo coronary artery bypass surgery are prescribed life-saving medications at discharge significantly less frequently than heart attack patients who receive less invasive angioplasty procedures, according to a new analysis by researchers at the Duke Clinical Research Institute.
These findings are important, the researchers said, because the drugs in question -- aspirin, ACE inhibitors, beta blockers and statins -- have been proven effective by multi-center clinical trials to reduce repeat cardiac events and death and therefore incorporated in established guidelines for care of heart attack patients. The researchers said much room exists for improving the usage rates of these life-saving drugs among all heart patients, including those who received angioplasty.
For example, the Duke team found that 65 percent of angioplasty patients received ACE inhibitors -- a class of blood vessel-relaxing drugs -- compared to only 44 percent of bypass patients. The cholesterol-lowering statins were prescribed for 76 percent of angioplasty patients and 62 percent of bypass patients.

From June 25th to 27th 2019, the Fraunhofer Institute for Digital Media Technology IDMT in Ilmenau (Germany) will be presenting a new solution for acoustic quality inspection allowing contact-free, non-destructive testing of manufactured parts and components. The method which has reached Technology Readiness Level 6 already, is currently being successfully tested in practical use together with a number of industrial partners.
Reducing machine downtime, manufacturing defects, and excessive scrap
The quality of additively manufactured components depends not only on the manufacturing process, but also on the inline process control. The process control ensures a reliable coating process because it detects deviations from the target geometry immediately. At LASER World of PHOTONICS 2019, the Fraunhofer Institute for Laser Technology ILT will be demonstrating how well bi-directional sensor technology can already be used for Laser Material Deposition (LMD) in combination with commercial optics at booth A2.431.
Fraunhofer ILT has been developing optical sensor technology specifically for production measurement technology for around 10 years. In particular, its »bd-1«...

Light can be used not only to measure materials’ properties, but also to change them. Especially interesting are those cases in which the function of a material can be modified, such as its ability to conduct electricity or to store information in its magnetic state. A team led by Andrea Cavalleri from the Max Planck Institute for the Structure and Dynamics of Matter in Hamburg used terahertz frequency light pulses to transform a non-ferroelectric material into a ferroelectric one.
Ferroelectricity is a state in which the constituent lattice “looks” in one specific direction, forming a macroscopic electrical polarisation. The ability to...
Researchers at TU Graz calculate the most accurate gravity field determination of the Earth using 1.16 billion satellite measurements. This yields valuable knowledge for climate research.
