Summary
Severe hypertension caused cardiac failure in two newborns. Renal abnormalities were identified, and infants became normotensive post-treatment, suggesting a renovascular origin for infant hypertension and heart failure.
Area of Science:
- Pediatric Cardiology
- Nephrology
- Neonatology
Background:
- Neonatal cardiac failure can present with diverse etiologies.
- Hypertension in neonates is less commonly associated with cardiac failure than hypotension.
Observation:
- Two newborn infants presented with cardiac failure secondary to severe hypertension.
- Cardiac dysfunction resolved with treatment of hypertension.
- Both infants exhibited renal abnormalities and were normotensive at 18 months follow-up.
Findings:
- The study identified a link between severe hypertension and cardiac failure in neonates.
- Renal abnormalities were consistently present in affected infants.
- Resolution of hypertension led to normalization of cardiac function.
Implications:
- Elevated blood pressure should be considered in neonates with cardiac failure, especially when primary cardiac pathology is absent.
- Renal or renovascular causes should be investigated in infants presenting with unexplained hypertension and cardiac compromise.
- Early identification and management of renovascular hypertension can prevent long-term cardiac sequelae in neonates.
