We evaluated the behavior of serum albumin concentrations in response to metabolic stress that is associated with cardiac surgery and the role of this protein as a predictor of clinical outcome in children at high surgical risk who undergo operative correction of congenital heart defects. ⋯ The results suggest that hypoalbuminemia is common among children who have heart disease and are at high surgical risk, and serum albumin concentrations lower than 3 g/dL may be related to outcome in the period after cardiac surgery.
