Key result
Cheyne-Stokes respiration was completely absent in children with congestive heart failure (0%) compared to a 40% prevalence in adults with the condition, suggesting it is an age-dependent phenomenon.
Why the study?
Does the prevalence of Cheyne-Stokes respiration differ between children with CHF, adults with CHF, and healthy children?
Case-Control (n=30)
No
Does the prevalence of Cheyne-Stokes respiration differ between children with CHF, adults with CHF, and healthy children?
Absolute Event Rate: 0% vs 40%
p-value: p=<0.05
The complete absence of Cheyne-Stokes respiration in children with CHF compared to adults suggests that CSR is an age-dependent phenomenon.
No takes yet. Share an insight, caveat, or question.
May not apply adult CSR thresholds to pediatric CHF; leaves open prospective confirmation of age dependence.
Avivit Peer (2010) conducted a case-control in Congestive heart failure (n=30). Childhood (young age) vs. Adulthood (older age) was evaluated on Prevalence of Cheyne-Stokes respiration (CSR) (p=<0.05). Cheyne-Stokes respiration was completely absent in children with congestive heart failure (0%) compared to a 40% prevalence in adults with the condition, suggesting it is an age-dependent phenomenon.
