Neonatal hypertension and cardiac failure.

Two newborn infants developed cardiac failure due to severe hypertension which was recognised as the heart failure was treated. Renal abnormalities were found in both infants who are normotensive off treatment at 18 months follow up. The finding of hypertension rather than hypotension in the presence of cardiac failure and the apparent absence of a cardiac abnormality should prompt a search for a renal or renovascular cause.
