Summary
Obstructive sleep apnoea (OSA) significantly impacts cardiovascular health, increasing risks for conditions like hypertension. Treating OSA with continuous positive airway pressure can improve cardiovascular function.
Area of Science:
- Cardiology
- Sleep Medicine
- Public Health
Background:
- Obstructive sleep apnoea (OSA) has acute and chronic physiological effects on the cardiovascular system.
- Growing evidence links OSA as an independent risk factor for various cardiovascular diseases (CVD).
Purpose of the Study:
- To review the association between obstructive sleep apnoea and cardiovascular disease.
- To highlight the impact of OSA treatment on cardiovascular parameters.
Main Methods:
- Literature review of existing studies on OSA and cardiovascular outcomes.
- Analysis of evidence for a causal link between OSA and specific cardiovascular disorders.
- Examination of treatment effects of continuous positive airway pressure (CPAP) on CVD markers.
Main Results:
- OSA is strongly associated with hypertension, with growing evidence for other cardiovascular disorders.
- Ongoing trials are expected to further solidify the link between OSA and CVD.
- CPAP treatment improves blood pressure in hypertensive patients and left ventricular ejection fraction in heart failure patients.
Conclusions:
- OSA is a significant independent risk factor for cardiovascular disease.
- Early identification and treatment of OSA are crucial for managing cardiovascular health.
- Healthcare providers should consider OSA symptoms in patients with existing CVD.
