Cardiac hypertrophy and insulin therapy in a pre-term newborn: is there a relationship?

Area of Science:

• Neonatal Cardiology
• Endocrinology
• Pediatric Pathology

Background:

• Hypertrophic cardiomyopathy (HCM) in newborns is rare with varied causes.
• The link between hyperinsulinism and cardiac hypertrophy is established, but hyperinsulinemia as an HCM cause is unreported.
• This study explores a novel potential etiology for neonatal HCM.

Observation:

• A case of cardiac hypertrophy (CH) in an Extremely Low Birth Weight (ELBW) infant is presented.
• The infant received insulin therapy for persistent hyperglycemia due to parenteral nutrition (PN).
• This therapeutic intervention preceded the observed cardiac hypertrophy.

Findings:

• The infant developed cardiac hypertrophy following insulin administration.
• This suggests a potential role for iatrogenic hyperinsulinemia in HCM development.
• The findings link insulin therapy to cardiac structural changes in neonates.

Implications:

• Close cardiological monitoring is crucial for infants receiving insulin infusions.
• Altered glucose metabolism and subsequent insulin therapy may pose risks for cardiac development.
• This case expands the understanding of HCM etiologies in the neonatal population.
