Obstructive sleep apnoea (OSA) may aggravate heart failure through the mechanisms of sleep related arousals, systemic hypertension (awake and asleep) and negative intrathoracic pressure which increase cardiac afterload at times of asphyxia and hypoxaemia. Reversal of OSA with nasal continuous positive airway pressure (CPAP), in the setting of heart failure, may return cardiac function to near normal values.

心力衰竭和阻塞性呼吸暂停。

阻塞性睡眠呼吸暂停（OSA）可能通过与睡眠有关的唤醒，全身性高血压（清醒和入睡）和胸腔内负压的机制加重心力衰竭，在窒息和低氧血症时会增加心脏后负荷。在心力衰竭的情况下，鼻持续持续气道正压通气（CPAP）逆转OSA可使心脏功能恢复至接近正常值。
