Sleep-related breathing disorders（SRBD）are observed in approximately 50% of patients with heart failure（HF）and in 5–10% of patients without HF, half of which are cases of central sleep apnea（CSA）. It is known that there may be a shift between CSA and obstructive sleep apnea（OSA）overnight and/or during follow-up. Although the multiple sleep latency test shows objective sleepiness in patients with SRBD and HF, patients do not complain of subjective sleepiness. Treatment is based on the type of SRBD. Continuous positive airway pressure（CPAP）is the first choice of treatment for OSA, whereas CPAP, adaptive servo-ventilation（ASV）, and/or oxygen therapy are used for CSA after providing proper medication for HF. Several multicenter randomized controlled trials with ASV have not shown improvement in the prognosis of CSA in patients with HF. During the post-operative period, surgical interventions may bring about exacerbation or shifts in SRBD.
