Diagnosis And Treatment of Sleep Apnea in Patient With Heart Failure

DASAP-HF is an observational prospective single arm study. All patients will be treated according to the standard care followed by each center. The protocol requires enrollment of consecutive patients from each center, according to eligibility criteria. All patients must sign the Patient Informed Consent (PIC) before the enrollment in the study. All patients, after the enrollment phase, will be followed for 24 months. Approximately every 12 months a clinical follow-up procedure should be performed in each patient. A sleep study will be done in all patients at 1 month (or at 3 months) from the enrollment, in order to evaluate the performance of the algorithm as a diagnostic tool in this population (primary objective). During the 24 months follow-up period, all Adverse Events occurred in the study population will be collected (HF hospitalizations, all-cause deaths, ventricular arrhythmias, etc.). At the end of the 24 months follow-up, the incidence of clinical events will be evaluated as well as its association with the Respiratory Disturbance Index (RDI) values calculated by APNEA Scan algorithm (secondary objective).
