The results of a study presented today at the American College of Cardiologys 53rd Scientific Sessions in New Orleans concludes that coronary aneurysms -- regardless of size -- are associated with a increased risk of death over a five year period and should be aggressively monitored.
The University of Chicago Hospitals and Emory Heart Center researchers studied the records of 32,372 patients undergoing coronary angiography at Emory University Hospitals in Atlanta between 1995 and 2003 and identified 276 with coronary artery aneurysms (abnormal enlargement or bulging of arteries) .The presence of an aneurysm of any size was found to have an adverse effect on long-term mortality similar to diabetes, coronary artery disease (CAD) and high cholesterol levels. "The results also show that no single risk factor -- CAD, hypertension, hyperlipidemia, diabetes, sex, or age -- was associated with the size of an aneurysm," says Emory Heart Center cardiologist Laurence S. Sperling, MD, co-author of the study. Other study authors are Timir S. Baman, MD; Jason H. Cole, MD; and Chandan M. Devireddy, MD.
"In addition, we found these patients have a predicted 5-year mortality rate of 29.1% -- a figure that is somewhat troubling, especially with the marked improvement in medical technology over recent years," Dr. Sperling, Director of Preventive Cardiology at Emory, adds. "In light of these findings, we believe all patients with angiographic evidence of coronary aneurysms should receive aggressive modification of coronary risk factors -- whether or not serious coronary disease is present. This research shows that clinicians should take all coronary aneurysms, regardless of size, seriously and monitor them aggressively."

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.
Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...
Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.
Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...
Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.
As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...
Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.
With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
