Effectiveness of Adaptive Servo-Ventilation for Treating Heart Failure Regardless of the Severity of Sleep-Disordered Breathing

摘要

Background: ?It is unclear whether adaptive servo-ventilation (ASV) is effective for all patients with heart failure (HF). The aim of the present study was therefore to investigate the effectiveness of ASV for all patients with HF. Methods and Results: ?Sixty-one patients with HF were recommended for ASV treatment, regardless of sleep-disordered breathing (SDB) severity and type. On the basis of the apnea-hypopnea index (AHI) results, patients were classified into 3 groups: 28 patients with AHI ≥40/h were designated as group A; 20 patients with AHI ≥20/h and
