Clinical experience indicates that infants and young children respond to a variety of cardiovascular pharmacological and physiological interventions differently than adults. What is less clear, however, are the cellular and molecular mechanisms that contribute to these age-related differences. Based largely upon results from animal models, it is apparent that developmental changes occur in numerous pathways and proteins involved in the regulation of contractile function and in the determinants of inotropic responsiveness. The purposes of this review are to provide a brief overview of cardiac excitation–contraction and to illustrate some of the important age-related differences in the mechanisms involved in calcium regulation in the heart. This scientific foundation may help to explain certain clinical observations in the very young. Furthermore, it is hoped that a better understanding of the fundamental processes involved in controlling cardiac contractile function will stimulate additional research in the search for more specific, rational and age-appropriate cardiovascular therapeutics. |
