Background: The SERVE-HF study has raised questions concerning the higher mortality under adaptive servoventilation. The ventilatory mode was discussed as a possible aggravating factor. Objectives: We wondered if the data recorded by the adaptive servo-ventilation (ASV)-devices in heart failure patients with CSA-CSR ± OSA are different in terms of respiratory parameters and therapeutic pressures compared to patients with CPAP-resistant/emergent-CSA with normal BNP/NT-pro-BNP. Methods: Patients were included, if ASV had normalized respiratory disturbance index in the first night of application and after at least 6 weeks. ASV-device data were analyzed in terms of respiratory rate (RR), min ventilation (MV), endexpiratory (EEP), peak inspiratory pressure (Ppeak) and median pressure. Results: Compared to CPAP-resistant/emergent-CSA with normal BNP/NT-pro-BNP (n = 25), CSA-CSR- (n = 13) CSA-CSR+OSA-patients (n = 32) with elevated BNP/NT-pro-BNP had higher RR (p < 0.01) in the first night of ASV therapy and during follow-up (15.3 ± 1.3 vs. 17.3 ± 2.4/min) with similar MV (6.5 ± 1.3 vs. 6.6 ± 1.3 L), resulting in significantly lower tidal volumes. EEP (5.6 ± 1.1 vs. 5.5 ± 1.1 hPa), Pmedian and Ppeak (9.8 ± 1.5 vs. 9.7 ± 1.2 hPa) were comparable. Ventilatory parameters were not different between LVEF < 40, 40–49, and ≥50%, neither within the whole group nor the group of CSA-CSR ± OSA and heart failure. Conclusion: Patients with heart failure and CSA-CSR ± OSA have higher RRs but similar MV under ASV-therapy than patients with CSA and normal BNP. This indicates higher dead space ventilation. EF was not found to have an influence on the ventilatory parameters.
