The growing evidence of independent association of obstructive sleep apnoea (OSA) with cardiovascular disease and the recent negative reports of benefit from nasal continuous positive airway pressure (CPAP) outcome studies justify a detailed exploration of the association of OSA with cardiovascular diseases and their outcomes, which provides the rationale for this special supplement in the Journal. The collection of papers covers the most important cardiovascular disorders associated with OSA and are written by internationally recognised experts on the respective topics.
