[Congestive heart failure in rickets caused by vitamin D deficiency]
Insights
Congestive heart failure in an infant was caused by low calcium levels due to vitamin D deficiency rickets. Prompt calcium therapy effectively treated the heart failure.
Area of Science:
- Pediatric Cardiology
- Nutritional Deficiencies
- Endocrinology
Background:
- Congestive heart failure (CHF) in infants can stem from various etiologies, including cardiac and metabolic causes.
- Hypocalcemia, a condition of low serum calcium, can lead to significant cardiovascular compromise.
- Vitamin D deficiency rickets is a preventable condition with potential systemic effects.
Observation:
- A three-and-a-half-month-old infant presented with symptoms of severe congestive heart failure.
- Diagnostic workup revealed profound hypocalcemia as the underlying cause of the cardiomyopathy.
- The infant's condition was attributed to vitamin D deficiency rickets.
Findings:
- The infant's hypocalcemic cardiomyopathy presented as congestive heart failure.
- Vitamin D deficiency rickets was identified as the primary cause of the hypocalcemia.
- Cardiovascular function improved significantly with calcium supplementation.
Implications:
- This case highlights the critical role of calcium in cardiac function in infants.
- Early diagnosis and management of vitamin D deficiency are crucial to prevent severe complications like heart failure.
- Screening for metabolic causes should be considered in infants presenting with unexplained cardiomyopathy.
Abstract:
We describe a case of a three and half month old infant presenting with a congestive heart failure due to hypocalcemic cardiomyopathy. Vitamin D deficiency rickets was found to be the cause for the hypocalcemia. The heart failure responded promptly to adequate Calcium therapy accompanied by usual anticongestive therapy.
