Heart attack calculator

19.12.2008
Writing in the inaugural issue of the International Journal of Knowledge Engineering and Soft Data Paradigms to be published in January, Greek researchers describe a quick and easy artificial intelligence approach to working out heart attack risk.

Physicians could use their system to provide patients with a personal risk factor and so advise on lifestyle changes or medication to lower their risk.

It is well known that lifestyle factors including depression, education, smoking, diet, and obesity, play a part in the risk of cardiovascular disease. However, epidemiologists who study how health risks vary through populations have not found a way to extrapolate from such broad studies to individual risk levels.

Now, Hara Kostakis of the TEI Piraeus Research Centre, in Methonis, Greece, and colleagues have investigated patterns of cardiovascular risk factors in a large population. They obtained data for almost 1000 patients enrolled in the CARDIO 2000 study who had been hospitalised with the first symptoms of ACS, acute coronary syndrome. They recorded details of body mass index, family history, physical activity, high blood pressure, high cholesterol, and diabetes were recorded. They then matched the data against healthy individuals as a scientific control.

Rather then using conventional methods for analysing statistics, the researchers borrowed an approach from the computer science field of artificial intelligence, OLAP. Online analytical processing was developed in the early 1990s and was exploited primarily in industrial and commercial applications, for financial and marketing analysis.

Fundamentally, OLAP provides a multidimensional view of data that allows patterns to be discerned in even the largest datasets that remain invisible even to the most expert user of spreadsheets. In a standard model, sales, purchases, pricing, customer base, and other economic measurements are used, Kostakis' colleagues at the University of Patras have adapted this system instead to accommodate the risk factors of heart disease.

The team points out that the CARDIO2000 study explored the association between several demographic, nutritional, psychological, lifestyle and medical risk factors, but did not necessarily provide epidemiologists and physicians with a way to visualise the results and so provide patients with a personal risk factor based on their particular circumstances.

Kostakis and his colleagues add that their approach works much more quickly than conventional statistical analysis, reveals hidden risk factors and associations and makes none of the assumptions of standard approaches to assessing risk of heart attack.

"Due to the ease of use of the methodology, a physician has the advantage of easily identifying high-risk patients by simply entering their personal data in the model," the researchers conclude. They can then advise their patient on lifestyle and psychological. They can also prescribe more appropriate medication depending on the specific risk factors.

Im Focus: Dresdner scientists print tomorrow’s world

The Fraunhofer IWS Dresden and Technische Universität Dresden inaugurated their jointly operated Center for Additive Manufacturing Dresden (AMCD) with a festive ceremony on February 7, 2017. Scientists from various disciplines perform research on materials, additive manufacturing processes and innovative technologies, which build up components in a layer by layer process. This technology opens up new horizons for component design and combinations of functions. For example during fabrication, electrical conductors and sensors are already able to be additively manufactured into components. They provide information about stress conditions of a product during operation.

The 3D-printing technology, or additive manufacturing as it is often called, has long made the step out of scientific research laboratories into industrial...

Im Focus: Three Magnetic States for Each Hole

Nanometer-scale magnetic perforated grids could create new possibilities for computing. Together with international colleagues, scientists from the Helmholtz Zentrum Dresden-Rossendorf (HZDR) have shown how a cobalt grid can be reliably programmed at room temperature. In addition they discovered that for every hole ("antidot") three magnetic states can be configured. The results have been published in the journal "Scientific Reports".

Physicist Dr. Rantej Bali from the HZDR, together with scientists from Singapore and Australia, designed a special grid structure in a thin layer of cobalt in...
