We evaluated whether VOCs analysis can discriminate patients with or without CHF, stratify CHF severity and predict the response to therapy of decompensated CHF.\n                    <jats:italic>Methods and Results<\/jats:italic>\n                    : We recruited 89 subjects admitted to an acute care ward with acutely decompensated CHF, 117 healthy controls and 103 chronic obstructive pulmonary disease (COPD) controls. CHF patients performed echocardiography. VOCs were collected using the Pneumopipe\n                    <jats:sup>\u00ae<\/jats:sup>\n                    and analyzed with the BIONOTE electronic nose. Partial least square analysis was used to evaluate the discriminative capacity of VOCs. Accuracy in discrimination of CHF versus healthy and COPD controls was 81% and 69%, respectively; accuracy did not decrease in a sensitivity analysis excluding subjects younger than 65 and older than 80 years. In CHF patients VOCs pattern could predict with fair precision ejection fraction and systolic pulmonary arterial pressure, but not changes in weight due to therapy.\n                    <jats:italic>Conclusions<\/jats:italic>\n                    : VOCs pattern is able to discriminate older CHF patients from healthy people and COPD patients and correlates with cardiac function markers.\n                  <\/jats:p>","DOI":"10.1088\/1752-7163\/aa8cd4","type":"journal-article","created":{"date-parts":[[2018,2,6]],"date-time":"2018-02-06T12:14:23Z","timestamp":1517919263000},"page":"026007","update-policy":"https:\/\/doi.org\/10.1088\/crossmark-policy","source":"Crossref","is-referenced-by-count":19,"title":["Analysis of volatile organic compounds: an innovative approach to heart failure characterization in older patients"],"prefix":"10.1088","volume":"12","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-8608-9223","authenticated-orcid":false,"given":"P","family":"Finamore","sequence":"first","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"C","family":"Pedone","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"D","family":"Lelli","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"L","family":"Costanzo","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"I Rossi","family":"Bartoli","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"A","family":"De Vincentis","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"S","family":"Grasso","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"F Romana","family":"Parente","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"G","family":"Pennazza","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"M","family":"Santonico","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"R Antonelli","family":"Incalzi","sequence":"additional","affiliation":[{"name":"Campus Bio-Medico University"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"266","published-online":{"date-parts":[[2018,2,6]]},"reference":[{"key":"jbraa8cd4bib1","doi-asserted-by":"publisher","first-page":"368","DOI":"10.1038\/nrcardio.2016.25","type":"journal-article","article-title":"Epidemiology and aetiology of heart failure","volume":"13","author":"Ziaeian","year":"2016","journal-title":"Nat.
