Among men without heart disease but who have significant cardiac risk factors, a poor performance on an exercise treadmill test is associated with more than doubling of the risk for a heart attack or other coronary heart disease event, according to a report in Circulation: Journal of the American Heart Association.
Exercise treadmill testing is not generally recommended as routine screening for people with no history or symptoms of heart disease. This is the first study to evaluate exercise testing among asymptomatic people relative to their predicted coronary heart disease (CHD) risk using the Framingham risk score.
The Framingham Risk Score assigns point values to risk factors such as high blood pressure, total cholesterol, HDL cholesterol, age, diabetes and smoking history to predict the risk of an event such as chest pain, heart attack or coronary death over a 10-year period. A risk score of 9 percent or less is considered low risk, 10 percent to 19 percent is considered intermediate risk, while a score of more than 20 percent, meaning that the person has a one in five chance of an event in 10 years, is classified as high risk. "Our results suggest that exercise testing may be of benefit in asymptomatic men with intermediate to high risk," said Gary J. Balady, M.D., a professor of medicine at Boston University School of Medicine and an investigator with the Framingham Heart Study.

At this year's LASYS, the LZH will exhibit light-based processes such as cutting, welding, ablation and structuring as well as additive manufacturing for...
There are videos on the internet that can make one marvel at technology. For example, a smartphone is casually bent around the arm or a thin-film display is rolled in all directions and with almost every diameter. From the user's point of view, this looks fantastic. From a professional point of view, however, the question arises: Is that already possible?
At Display Week 2018, scientists from the Fraunhofer Institute for Applied Polymer Research IAP will be demonstrating today’s technological possibilities and...

A team led by Austrian experimental physicist Rainer Blatt has succeeded in characterizing the quantum entanglement of two spatially separated atoms by observing their light emission. This fundamental demonstration could lead to the development of highly sensitive optical gradiometers for the precise measurement of the gravitational field or the earth's magnetic field.
The age of quantum technology has long been heralded. Decades of research into the quantum world have led to the development of methods that make it possible...
