Abstract

Objective

The purpose of this study was to evaluate the cardiac functions and age-related changes of these functions in full-term small for gestational age infants during the first 3 months of life.

Methods

Cardiac functions of 20 term small for gestational age and 20 term appropriate for gestational age infants were studied using conventional and tissue Doppler echocardiography on postnatal day 5 and at 1 and 3 months.

Results

Ventricular diameters, ventricular wall thicknesses, and left ventricular mass significantly increased with age in both groups. All these parameters were significantly lower in small for gestational age infants. No differences were detected by conventional echocardiography between the groups in systolic and diastolic functions. Systolic velocity, early diastolic and atrial contraction velocities, and the ratio between early diastolic and atrial contraction velocities determined by tissue Doppler echocardiography increased with age. Systolic velocity was lower in the small for gestational age babies for all myocardial regions on the 5th day. Peak early diastolic velocity was decreased in the small for gestational age babies at the first and second evaluations for all myocardial regions. The ratio between early diastolic and atrial contraction velocities was significantly lower in the small for gestational age babies for the interventricular septum and right ventricle. Significant positive correlations were detected between the Ponderal index and systolic and early diastolic velocities.

Conclusion

The present findings suggest that systolic and diastolic function indices including tissue Doppler measures are significantly affected in small for gestational age babies during the first 3 months of life.
