Cardiovascular consequences of obstructive sleep apnoea.

Obstructive sleep apnoea (OSA) is associated with multiple cardiovascular complications.

• OSA is often underdiagnosed despite its high prevalence rate.
• It is linked to conditions such as hypertension, coronary artery disease, stroke, and heart failure.
• The presence of OSA may strongly predict fatal cardiovascular events in individuals with cardiovascular disease.
• Proposed mechanisms for the association include increased sympathetic drive and impaired vascular function.
• Understanding the mechanisms of OSA is important for developing treatment strategies.
• Randomized intervention studies are needed to determine if early detection and treatment of OSA can reduce cardiovascular issues.
