There is an increasing interest in simple and affordable tools to screen patients and monitor these disorders at home on a long-term basis. We aimed to assess the pathophysiological and clinical relevance of a simplified method for monitoring of PB suitable to be self-managed by the patient at home.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods and results<\/jats:title>\n                    <jats:p>A night-time respiratory recording was performed in 397 optimally treated HF patients (age 60 \u00b1 11 years, NYHA class 2.4 \u00b1 0.6, left ventricular ejection fraction 29 \u00b1 7%) and the duration of PB (PBDur) automatically computed. Patients were followed-up for 1 year and the prognostic value of PBDur evaluated. In 45 patients, we assessed the association between PBDur and severity of oxygen desaturations (number of desaturations &amp;gt;3%). Twenty six of the 397 patients died of cardiac causes. A PBDur \u22652 h was significantly associated with an increased risk of cardiac death after adjustment for major clinical predictors [hazard ratio (95% CI): 3.5 (1.6\u20137.9), P = 0.002]. The correlation between PBDur and severity of desaturations was 0.94 (P &amp;lt; 0.0001).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Relevant pathophysiological and clinical information can be obtained from simplified monitoring of breathing disorders managed by the patient.
