Diabetes could be a hidden condition for heart disease patients

16.07.2008
Researchers at the University of Warwick have discovered diabetes could be a hidden condition for some patients with coronary heart disease.

In a study led by Dr Saverio Stranges, Associate Professor of Cardiovascular Epidemiology at Warwick Medical School, the team looked at levels of oxidative stress in the body (a toxic effect which causes cell damage).

They found high levels of oxidative stress in people with coronary heart disease, previously thought to be a marker of the heart condition, could instead indicate a condition of glucose abnormality, such as overt type 2 diabetes.

The research team took blood samples to contrast oxidative stress levels in people with coronary heart disease, people with type 2 diabetes and healthy control subjects. Previous studies have shown people with type 2 diabetes and people with coronary heart disease have high levels of oxidative stress.

Dr Stranges’ team expected to produce similar results, but they found that those stress levels were low in people with coronary heart disease but without type 2 diabetes. Further investigation showed people from this group with high levels also had overt type 2 diabetes.

The research used data taken from the Western New York Health Study. This was a case-control study of myocardial infarction and cardiovascular risk factors among residents of Erie and Niagara Counties, New York.

Dr Stranges said: “The results were intriguing. We expected to find high levels of oxidative stress in people with a clinical heart condition, such as myocardial infarction, and people with diabetes. As we thought, the levels were high for diabetics, but there were some discrepancies for people with heart disease.

“Our findings suggest the observed associations of increased oxidative stress in individuals with heart disease may be dependent on underlying abnormalities in glucose metabolism.”

Additional contributors to the study were Dr Joan Dorn, Professor Richard Donahue, Professor Jo Freudenheim, Kathleen Hovey and Professor Maurizio Trevisan from the Department of Social and Preventive Medicine, State University of New York at Buffalo, NY, USA; Dr Richard Browne from the Department of Biotechnical and Clinical Laboratory Sciences, State University of New York at Buffalo, NY, USA.

Im Focus: Abrupt motion sharpens x-ray pulses

Spectrally narrow x-ray pulses may be “sharpened” by purely mechanical means. This sounds surprisingly, but a team of theoretical and experimental physicists developed and realized such a method. It is based on fast motions, precisely synchronized with the pulses, of a target interacting with the x-ray light. Thereby, photons are redistributed within the x-ray pulse to the desired spectral region.

A team of theoretical physicists from the MPI for Nuclear Physics (MPIK) in Heidelberg has developed a novel method to intensify the spectrally broad x-ray...

Im Focus: Physicists Design Ultrafocused Pulses

Physicists working with researcher Oriol Romero-Isart devised a new simple scheme to theoretically generate arbitrarily short and focused electromagnetic fields. This new tool could be used for precise sensing and in microscopy.

Microwaves, heat radiation, light and X-radiation are examples for electromagnetic waves. Many applications require to focus the electromagnetic fields to...

Im Focus: Carbon Nanotubes Turn Electrical Current into Light-emitting Quasi-particles

Strong light-matter coupling in these semiconducting tubes may hold the key to electrically pumped lasers

Light-matter quasi-particles can be generated electrically in semiconducting carbon nanotubes. Material scientists and physicists from Heidelberg University...

Im Focus: Flexible proximity sensor creates smart surfaces

Fraunhofer IPA has developed a proximity sensor made from silicone and carbon nanotubes (CNT) which detects objects and determines their position. The materials and printing process used mean that the sensor is extremely flexible, economical and can be used for large surfaces. Industry and research partners can use and further develop this innovation straight away.

At first glance, the proximity sensor appears to be nothing special: a thin, elastic layer of silicone onto which black square surfaces are printed, but these...
