Insights
Obstructive sleep apnea syndrome (OSAS) significantly elevates cardiovascular risks, including heart failure and stroke. Reviewing cardiovascular biomarkers aids in early diagnosis and prognosis for OSAS patients.
Area of Science:
- Cardiology
- Sleep Medicine
- Biomarker Research
Context:
- Obstructive sleep apnea syndrome (OSAS) is linked to severe cardiovascular complications.
- These complications include coronary artery disease, heart failure, hypertension, and stroke, increasing OSAS morbidity and mortality.
- Heart failure patients may also experience sleep-related breathing disorders like Cheyne-Stokes respiration and various apneas.
Purpose:
- To review the role of cardiovascular biomarkers in the early diagnosis, treatment, and prognosis of OSAS.
- To explore the clinical significance of specific biomarkers in the context of OSAS-related cardiovascular pathology.
Summary:
- OSAS contributes to a range of cardiovascular issues, including ventricular dysfunction, heart failure, and arrhythmias.
- Hypoxemia-induced sympathetic overactivity and endothelial dysfunction are key mechanisms.
- Key biomarkers discussed include C-reactive protein (CRP), TNF-α, interleukins, adiponectin, hFABP, and BNP.
Impact:
- Highlights the importance of cardiovascular biomarkers for managing OSAS patients.
- Provides insights into the pathophysiological links between sleep apnea and heart disease.
- Aids clinicians in risk stratification and therapeutic decision-making for OSAS-related cardiovascular conditions.
Abstract:
Obstructive sleep apnea syndrome (OSAS) leads to cardiovascular complications such as coronary artery disease, left/right ventricular hypertrophy and dysfunction, heart failure, systemic and pulmonary hypertension, arrhythmias and stroke; and these all cardiovascular complications increase morbidity and mortality of OSAS. However, Cheyne-Stokes respiration, central and obstructive apneas may occur in the patient with heart failure. Increased sympathetic activity by hypoxemia and endothelial dysfunction play a role in cardiovascular complications. Some cardiovascular biomarkers have a role in early diagnosis, treatment and prognosis. In the present review, some cardiovascular biomarkers such as serum C-reactive protein (CRP), tumor necrosis factor-alpha (TNF-α), interleukins, adiponectin, heart-type fatty acid binding protein (hFABP) and brain (B-type) natriuretic peptide (BNP), and their clinical importance were reviewed.
