Summary
Obstructive sleep apnea syndrome (OSAS) is a major sleep disorder linked to cardiovascular diseases. Early diagnosis and treatment of OSAS can improve patient outcomes and reduce mortality risks.
Area of Science:
- Cardiology
- Sleep Medicine
- Pulmonology
Context:
- Obstructive sleep apnea syndrome (OSAS) is a prevalent sleep-related breathing disorder.
- OSAS is associated with significant cardiovascular morbidity and mortality.
- It is an independent risk factor for cardiovascular diseases and stroke.
Purpose:
- To elucidate the pathophysiological mechanisms linking OSAS to cardiovascular complications.
- To highlight the distinct phases of obstructive apnea and their hemodynamic/autonomic effects.
- To emphasize the increased risk in patients with co-existing coronary heart disease.
Summary:
- OSAS triggers acute hemodynamic changes, neurohumoral activation, and blood gas alterations during apneas.
- These changes contribute to systemic and pulmonary hypertension, and cardiac electrical instability.
- The condition is particularly dangerous in patients with coronary heart disease, leading to silent ischemia and arrhythmias.
Impact:
- Early detection and treatment of OSAS can mitigate cardiovascular risks.
- Effective management improves the long-term prognosis for patients with OSAS.
- Understanding these mechanisms is crucial for preventing severe cardiovascular events.
