Heart failure and neonatal hypocalcaemia.

O Troughton, S P Singh

    British Medical Journal
    |October 14, 1972
    PubMed
    Summary

    Low serum calcium (hypocalcemia) can cause congestive heart failure in infants. This condition is treatable, with most infants recovering fully after calcium supplementation.

    Area of Science:

    • Pediatrics
    • Cardiology
    • Neonatology

    Background:

    • Congestive heart failure in infants often presents with unknown etiology.
    • Edema is a common symptom that may indicate underlying metabolic disturbances.

    Purpose of the Study:

    • To investigate the potential link between hypocalcemia and congestive heart failure in infants.
    • To highlight hypocalcemia as a treatable cause of infant heart failure.

    Main Methods:

    • Observational study of six infants presenting with congestive heart failure.
    • Clinical evaluation, serum calcium level assessment, chest X-rays, and electrocardiograms (ECGs).
    • Necropsy performed on one non-surviving infant.

    Main Results:

    • All six infants had low serum calcium levels as the primary finding.
    • Five infants recovered completely with normal cardiac function and imaging after treatment.
    • The infant who died showed cardiac dilation, with necropsy revealing no other congenital abnormalities.

    Conclusions:

    • Hypocalcemia should be considered a potential cause of congestive heart failure in infants.
    • Prompt diagnosis and treatment of hypocalcemia can lead to favorable outcomes.
    • Early recognition is crucial, particularly in infants presenting with prominent edema.
