Central apneas (CA) and periodic breathing (PB) are the most common related breathing disorders in heart failure, being observed in up to 50% of patients. Once considered only a sleep-related phenomenon, actually CA/PB occur across the whole 24 h period and their presence in the awake patient even in the upright position and during physical effort has been associated with a worse clinical profile and a greater mortality. Chemoreflex activation, circulatory time delay and altered plant gain are the pathophysiological determinants. While the use of guideline-recommended medical and device treatment represents the first step in the management of CA in heart failure patients, no specific therapy has been demonstrated to reduce CA-related impact on mortality. In particular, the use of non-invasive ventilation has yielded contradictory results in the context of large-scale randomized clinical trials. The design and testing of therapies targeting the pathophysiological triggers of CA, such as chemoreflex sensitivity, may prove valuable in the next future.
