Useful assessment tools may be heart rate variability (HRV) analysis and\/or the study of norepinephrine (NPE) level. Nevertheless, traditional techniques of HRV analysis have proved not sufficient and the second is an invasive measurement. In this work the correlation between a parameter (kurtosis-K) computed by an emerging nonlinear technique, the symbolic dynamics analysis, and neurohormonal and functional parameters has been investigated. Results obtained show an interesting relationship between K and both ejection fraction and NPE. In particular, higher K values are associated to increasing NPE levels This finding could be useful for highlighting changes in HF patients otherwise detectable only with invasive examinations.<\/jats:p>","DOI":"10.3233\/978-1-61499-432-9-516","type":"book-chapter","created":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T14:45:03Z","timestamp":1740149103000},"source":"Crossref","is-referenced-by-count":0,"title":["Correlation Between Symbolic Dynamics Analysis Indexes and Neurohormonal and Functional Parameters in Heart Failure Patients"],"prefix":"10.3233","author":[{"family":"Cesarelli Mario","sequence":"additional","affiliation":[]},{"family":"Romano Maria","sequence":"additional","affiliation":[]},{"family":"Maestri Roberto","sequence":"additional","affiliation":[]},{"family":"La Rovere Maria Teresa","sequence":"additional","affiliation":[]},{"family":"Bifulco Paolo","sequence":"additional","affiliation":[]},{"family":"D'Addio Giovanni","sequence":"additional","affiliation":[]}],"member":"7437","container-title":["Studies in Health Technology and Informatics","e-Health &amp;ndash; For Continuity of Care"],"original-title":[],"deposited":{"date-parts":[[2025,2,21]],"date-time":"2025-02-21T14:46:52Z","timestamp":1740149212000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.medra.org\/servlet\/aliasResolver?alias=iospressISSNISBN&issn=0926-9630&volume=205&spage=516"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":0,"URL":"https:\/\/doi.org\/10.3233\/978-1-61499-432-9-516","relation":{},"ISSN":["0926-9630"],"issn-type":[{"value":"0926-9630","type":"print"}],"subject":[],"published":{"date-parts":[[2014]]}}}
