Extreme glucose levels in diabetic patients with heart failure linked to increase risk of deaths

22.07.2009
Compared with patients with moderately controlled glucose levels, diabetic patients who have heart failure and either too high or too low glucose levels may be at increased risk of death, said researchers at Baylor College of Medicine(www.bcm.edu) in a report published in the current issue of Journal of the American College of Cardiology.

To determine average glucose levels in the blood over a two to three month period, doctors measure glycosylated hemoglobin (the oxygen-carrying protein in the blood that is bound to the sugar glucose). In general, higher levels have been associated with increased risk of heart disease, said Dr. David Aguilar, assistant professor of medicine – cardiology at BCM (http://www.bcm.edu/news/broadcastcenter/expert.cfm?expertid=150).

"Most doctors try to keep glucose levels of those with diabetes as low as they can to lower the risk of complications such as eye problems, kidney disease or the development of heart disease," said Aguilar, senior author of the study. "However, we found that in diabetic patients with heart failure, glucose levels slightly higher than what are normally recommended had the lowest risk of death."

Researchers at BCM and the Michael E. DeBakey Veterans Affairs Medical Center (http://www.houston.va.gov/) in Houston identified 5,815 veterans with heart failure and diabetes who were receiving treatment at VA medical centers across the nation. They followed the patients for two years, dividing them into five categories based on their glycosylated hemoglobin levels.

Most medical professionals recommend levels at 7 and below as the target for optimal health for diabetic patients. However, the results of the study of diabetic patients with heart failure showed that those with levels 7.1 to 7.8 had the lowest rate of death. Those patients at both ends of the spectrum had the higher death risks.

"This doesn't mean that diabetic patients with heart failure should change their target goal for glucose levels," Aguilar said. "The results could simply be telling us that the glycosylated hemoglobin levels are a marker for other risks that are contributing to increased risk of death, but not necessarily the cause of the problem."

Aguilar said the correlation needs to be further investigated to confirm the findings and see what other factors could be contributing to the mortality rate.

The research is supported by a V.A. Health Services Research and Development Service grants and a National Institutes of Health Mentored Career Development Award.

Other researchers who took part in this study include, Drs. Biykem Bozkurt, Kumudha Ramasubbu and Anita Deswal, all from the Winters Center for Heart Failure Research and Section of Cardiology, and the Department of Medicine at BCM. Deswal is also at the Houston Center for Quality of Care and Utilization Studies at the Michael E. DeBakey V. A. Medical Center in Houston.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
