Obstructive sleep apnea: not just a sleep disorder.

Area of Science:

• Sleep Medicine
• Cardiology
• Endocrinology

Background:

• Obstructive sleep apnea (OSA) was historically viewed as a minor issue, primarily characterized by snoring and sleep disruption.
• Recent decades have revealed OSA's significant multisystem impact, including cardiovascular, metabolic, and neuropsychological consequences.
• Physicians and patients often underestimate OSA symptoms like snoring and daytime sleepiness, leading to delayed diagnosis and treatment.

Purpose of the Study:

• To review the characteristics, pathophysiology, and epidemiology of obstructive sleep apnea.
• To explore the mechanisms through which OSA influences cardiovascular, endocrine, and metabolic functions.
• To emphasize the importance of recognizing OSA for preventing severe health complications.

Main Methods:

• Literature review of obstructive sleep apnea characteristics, pathophysiology, and epidemiology.
• Analysis of mechanisms linking OSA to cardiovascular and metabolic disturbances.
• Synthesis of current understanding regarding OSA's multisystemic effects.

Main Results:

• OSA leads to fragmented sleep, cumulative sleep debt, and is associated with impaired work quality and accidents.
• Growing evidence links untreated OSA to increased atrial fibrillation recurrence post-cardioversion, poor diabetes control, and resistant hypertension.
• Physician awareness and inclusion of sleep in system reviews are crucial for diagnosing OSA and preventing its severe complications.

Conclusions:

• Obstructive sleep apnea is a serious disorder with widespread health implications beyond sleep disruption.
• Effective management of OSA, including continuous positive airway pressure (CPAP), is vital for mitigating cardiovascular and metabolic risks.
• Increased physician vigilance and patient education are necessary for timely OSA diagnosis and improved patient outcomes.
