Abstract
PURPOSE: Adaptive servo-ventilation (ASV) is a ventilator algorithm able to correct breathing through anticyclic support of breathing in patients with central sleep apnea (CSA). So far, very few data exist regarding the role of ASV on acute heart failure with preserved ejection fraction (HFpEF). METHODS: We performed a single-center prospective, randomized, case-control study in consecutive acute HFpEF (left ventricle ejection fraction, LVEF ≥ 45%) patients with sleep-disordered breathing (SDB, apnea-hypopnea index, AHI > 15/h) and prevalence of CSA. RESULTS: We included ten consecutive patients randomized for ASV on top of standard therapy for acute heart failure (group 1) versus standard care alone (group 2). ASV therapy significantly reduced AHI and CSA. An improvement in cardiac diastolic function was seen in group 1 compared to group 2 (E/E' 17.5 to 9.6, p
