Growth disturbance in weight and height is noted in children with congenital heart disease. A number of causative factors have been proposed. These include chronic tissue hypoxia, pulmonary hypertension, congestive heart failure, frequent respiratory infections and altered nutrition. This study is designed to analyse the growth pattern of Chinese infants and children with congenital heart disease. A total of 3,980 infants and children who underwent cardiac catheterization in three hospitals were studied. Their weight and height were compared with those of normal infants and children. Growth disturbance was found in both groups of infants with cyanotic and acyanotic congenital heart diseases (P<0.005). Those without cyanosis were less severely retarded than those with persistent cyanosis. In 47-62% of the cyanotic patients, their weight and height were found to be below the 16th percentile of normal, while in 16-40% of the acyanotic group they were below the 16th percentile. No correlation was noted between the degree of growth retardation and the size of left-to-right shunts in all patients (P>0.1), except those in the groups below two years of age (P<0.05). It is concluded that congenital heart disease exerts a significant influence on the growth of infants and children.
