Heart failure in children: clinical aspect and management.

Heart failure (HF) is a complex syndrome, with several definitions, the commonest being "an abnormality of cardiac function whereby heart in unable to pump at a rate commensurate with the requirement of the metabolizing tissues, or does so only at elevated filling pressures". In case of children, this requirement includes growth and development. Unlike as seen in adults, HF in children is commonly due to structural heart disease and reversible conditions. Thus the treatment for HF is commonly required for short term only. The overall outcome with HF is better in children than in adults. While the general principles on management are similar to those in adults, the evidence for the use of drugs in children is less convincing. It requires a judicious balance of extrapolation from adult medicine, keeping in mind that children are not small adults.
