Childhood sleep-disordered breathing and its implications for cardiac and vascular diseases

Area of Science:

• Pediatric Cardiology
• Sleep Medicine
• Cardiovascular Research

Background:

• Childhood sleep-disordered breathing (SDB), encompassing obstructive sleep apnoea (OSA), is a growing concern.
• Emerging evidence suggests potential links between pediatric SDB/OSA and adverse cardiovascular outcomes.
• Understanding this relationship is crucial for early detection and prevention of pediatric cardiovascular diseases.

Purpose of the Study:

• To systematically review and synthesize recent scientific literature on the association between SDB/OSA and cardiovascular diseases in children.
• To evaluate the evidence for SDB/OSA's impact on blood pressure, sympathetic activity, arterial function, cardiac structure, and metabolic health in pediatric populations.

Main Methods:

• Comprehensive literature search on SDB/OSA and cardiovascular parameters in children.
• Inclusion of studies examining blood pressure, sympathetic activation, arterial distensibility, ventricular hypertrophy, and insulin resistance.
• Meta-analysis conducted for the risk of hypertension associated with a high apnoea-hypopnoea index, yielding an odds ratio of 2.93.

Main Results:

• A significant association between SDB/OSA and hypertension in children was suggested.
• Evidence indicates SDB/OSA may influence blood pressure in children, though data require further substantiation.
• Limited findings point to SDB/OSA being linked to increased sympathetic activation, reduced arterial distensibility, and ventricular hypertrophy.

Conclusions:

• There is growing, yet insufficient, evidence linking childhood SDB/OSA to identifiable cardiovascular abnormalities.
• Further robust research is necessary to establish definitive causal relationships and clinical implications.
• Early recognition of SDB/OSA in children may be important for monitoring cardiovascular health.
