Electronic Nose Sniffs Out Heart Failure
Electronic Nose Sniffs Out Heart Failure
Aug. 30, 2011 (Paris) -- German researchers say they’re a step closer to developing an electronic nose that can distinguish between people who have heart failure and those who don't.
The device has gas sensors that detect various odorous molecules in sweat. Specially developed software divides patients into groups depending on the pattern of molecules detected.
"We saw two distinct patterns, one of which correlated with heart failure," says study leader Vasileios Kechagias, a PhD candidate at the University Hospital Jena.
The goal of the project is to develop a simple, accurate, noninvasive, and reproducible method for early identification of chronic heart failure, he tells WebMD.
