New way to assess risk of heart disease in ethnic groups

07.06.2006


A new web-based calculator will better assess the risk of heart disease in British black and minority ethnic groups. These groups are often wrongly assessed.



ETHRISK is for everyday use in the doctor’s surgery and other primary care settings. It has been developed by researchers at the University of Bristol to improve prediction of the heart disease risks of seven British black and minority ethnic groups.

Ethnic groups within Britain have a different risk of coronary heart disease (CHD) and cardiovascular disease (CVD), when compared with the general population in Britain. However, their risks are not being correctly assessed, due to the outdated method of calculation.


Dr Peter Brindle, lead author on the paper published online today in the BMJ journal Heart, said: “The ETHRISK calculator adjusts for ethnic groups and is based on a re-calibration of the Framingham risk equations. It provides a much more realistic assessment of the risk of having heart disease and stroke within a 10-year period, faced by an individual from one of these groups.

“Once the blood pressure and cholesterol measurements have been taken, the nurse or doctor can go online and plug in the numbers to get a more accurate risk score for that individual. ”

The recommended way of preventing heart disease involves using the Framingham risk score to identify high-risk patients. Patients above an agreed threshold are prescribed preventive treatments. However, the relevance of the Framingham score to the British population is uncertain, particularly when applied to ethnic groups, because the US data on which Framingham is based, are over 20 years old.

This means that people in some ethnic groups may not be picked up as being at high risk, while others are taking drugs unnecessarily since their risk is being over-estimated.

Professor Peter Weissberg, Medical Director of the British Heart Foundation which funded the study, said: “We have known for some time that some ethnic groups are at particularly high risk of cardiovascular disease and that applying the conventional rules to predict their future risk of a heart attack was probably underestimating that risk.

“The Bristol University group have produced a risk assessment tool that adjusts for ethnic origin. This should help doctors to address some of the current inequalities in the provision of preventive medicine to ensure that those at highest risk, regardless of their background, are identified and treated before they develop heart disease.”

The data on which the recalibration has been calculated included 3,778 men and 4,544 women, aged 35-54, from the Health Survey for England 1998/99, and the Wandsworth Heart and Stroke Study.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
