Childhood prognosis of heart disease in later life

24.06.2008
Heart diseases are one of the major causes of death in the western world.

Research is under way in the University of Leicester Engineering Department, in collaboration with The Leicester Royal Infirmary, to analyse the heart rate variability of 10 year- old children, in an attempt to identify heart diseases at an early stage.

The detection of heart diseases in early life will give us a better understanding of the way we live, eat, and do sports. Eventually a healthier lifestyle can be recommended for a longer healthier life.

The study involved a set of 24-hour ECG data from 75 children, 41 of whom were diagnosed as intrauterine growth restricted (IUGR) and 34 as normal.

Heart rate variability measures were obtained from the data and many signal processing and mathematical methods were used to identify any abnormalities. Other data were available, such as gender, parental smoking, breast feeding, gestational period, body mass index, deprivation index, day and night blood pressure and many other factors.

Taher Biala, a postgraduate researcher working on the project commented: “The research so far has given us a better understanding of the heart rate variability and consequently the function of the autonomic nervous system.

“The relaxed mode of the heart (parasympathetic tone) can be easily identified at night time when the heart rate decreases. In the day time the sympathetic tone is dominant and heart rate increases due to different activities of the subject.”

Factors such as gender, body mass index, and deprivation index were found to be an important factor in this study. Male children have a more relaxed heart beat (a stronger parasympathetic tone) than females and an associated lower heart rate.

A lower body mass index is positively correlated with a lower heart rate. With regard to deprivation index (social class) it was found that there is a significant difference between the two groups under study.

Taher A.Biala BSc (Electrical & Electronics), MSc. Before commencing his Phd, he was a lecturer at the Higher Institute of Medical Technology, Misurata / Libya. His current research interest is signal processing of physiological data such as ECG.

The research is being presented to the public at the University of Leicester on Thursday 26th June. The Festival of Postgraduate Research introduces employers and the public to the next generation of innovators and cutting-edge researchers, and gives postgraduate researchers the opportunity to explain the real world implications of their research to a wide ranging audience.

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....
