Heart screening unnecessary in type 2 diabetes patients with no symptoms

16.04.2009
Routine screening for coronary artery disease in type 2 diabetes patients with no symptoms of angina or a history of coronary disease is unnecessary and may lead initially to more invasive and costly heart procedures, according to researchers at Yale School of Medicine. They report their findings in the April 15 Journal of the American Medical Association.

"Patients with type 2 diabetes with no symptoms who are feeling well can generally be managed effectively with preventive therapies such as lipid-lowering drugs, blood pressure medication, aspirin and diabetes treatment," said Lawrence Young, M.D., professor of medicine at Yale School of Medicine.

Coronary artery disease is a major cause of death and disability in patients with type 2 diabetes, who often undergo routine screening with stress testing. In this study, Young, Frans J. Wackers, M.D., Silvio Inzucchi, M.D., Deborah Chyun, and other colleagues sought to determine whether routinely screening diabetic patients without a history of heart problems helped identify those at higher cardiac risk.

The team spearheaded the Detection of Ischemia in Asymptomatic Diabetics study in which 1,123 participants were randomly assigned to either a screening stress test that looks at the blood flow to the heart, or to a group that received no screening. Participants enrolled at 14 centers in the United States and Canada and were evaluated over the next five years.

The team found that routine screening of type 2 diabetics identifies a small group of patients at higher risk, but does not significantly affect overall outcome. With each test costing about $1,000, and with 200 million patients with diabetes worldwide, Young says, "Routine screening would have tremendous economic implications and our findings did not indicate that routine stress testing had additional benefit in this population." The study also found that routine screening leads initially to more invasive procedures such as cardiac catheterization, stents or bypass.

"On the other hand,ö he cautioned, ôstress testing has an important role in evaluating patients with type 2 diabetes who have symptoms suggesting heart disease, since these individuals are at very high risk."

"This is a bit of good news in the field of diabetes where patients and their physicians have real concern for heart disease. In patients getting modern medical therapy in our study, serious heart problems were infrequent," said Young.

Other authors on the study included Janice Davey, Eugene Barrett, M.D., Raymond Taillefer, M.D., Gary Heller, M.D., Ami Iskandrian, M.D., Steven Wittlin, M.D., Neil Filipchik, M.D., Robert Ratner, M.D.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

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...

Im Focus: Climate satellite: Tracking methane with robust laser technology

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...

Im Focus: How protons move through a fuel cell

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...

Im Focus: A unique data centre for cosmological simulations

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...
