What is Electronic Nose Detects Heart Failure from Exhaled Breath about?

Electronic noses (enoses) were a applied for diagnosing various diseases when analyzing gases from skin surface. The objective of this study was to prove if enoses are suitable for an early detection and monitoring of heart failure (HF) in a patient's breath. The exhaled breath was collected from 13 patients with decompensated HF (DHF), 16 patients of compensated HF (CHF) and 13 controls without HF (CON). Principal component analysis in combination with discriminant function analysis (DA) was used to discriminate between the patient groups. The breath samples were separated between DHF and CHF with an accuracy of 91% and between CON and CHF with 97%. The results suggest that an easy to use, inexpensive and non-invasive working enose could be applied for diagnosing and monitoring of HF patients based on the analysis of exhaled breath.
