A computerised sensor identifies the scent of heart failure and differentiates it from scent of a healthy person

Scientists have developed what they claim is an alt39 electronic nosealt39 which can alt39 smella

lt39 heart failure.

A team at the University Hospital Jena in Germany says the alt39 electronic nosealt39 system consists of an array of 3 thick- film metal oxide based gas sensors with heater elements. Each of the sensors had a slightly different sensitivity to various odorant molecular types. alt39 The early detection of chronic heart failure ( CHF) through periodical screening facilitates early treatment application,alt39 said Vasileios Kechagias, who led a team at the University Hospital Jena in Germany.

Heart failure is a common, costly, disabling and potentially deadly condition. Its linked to significantly reduced physical and mental health, resulting in a markedly decreased quality of life. Although some people survive many years, progressive disease is associated with an overall increased mortality and morbidity.

The researchers screened a total of 250 patients and included 126 in the study in which testing was optimised through a standardised skin preparation.
