  • secondary analysis of a longitudinal cohort study

Authors' conclusion

Neonatal CSI and rcSO2 associated with 3-month cognitive and motor outcomes in CHD and CHD subgroups, and groups differed in their directional associations. Future studies should explore CSI as an indicator of risk for developmental delays in CHD.

Study context

Population
Congenital heart disease (CHD) and control infantscontrol 41 · CHD 29
Participants
70 infants
Comparison
associations of neonatal cerebrovascular stability index (CSI) and rcSO2 with 3-month neurodevelopmental outcomes (NDOs) within CHD and control groups and within CHD subgroups; group and subgroup differences in these associations
  • CHDn = 29
  • controln = 41

Primary result

As reported in the abstract

Cognitive scores (Bayley-III) with CSI and rcSO2 in CHD infants · 3-month

CSI associated with cognitive scores in CHD

P = 0.03

rcSO2 associated with cognitive scores in CHD

P = 0.02

Further findings

Motor scores with CSI, CHD vs controls · 3-month

CSI positively associated with motor scores in CHD, did not associate in controls
P = 0.02

Cognitive scores with rcSO2, CHD vs controls · 3-month

rcSO2 positively associated with cognitive scores in CHD, negatively associated in controls
P = 0.01

Language scores with rcSO2 (biventricular subgroup) · 3-month

rcSO2 associated with language scores in the biventricular subgroup
P = 0.01

Motor and cognitive scores (cyanotic subgroup) · 3-month

CSI associated with motor scores in the cyanotic subgroup
P = 0.04
rcSO2 associated with cognitive scores in the cyanotic subgroup
P = 0.01
