We evaluated two groups of diabetic women in pregnancy who differed primarily in the time of initiation of careful diabetes management. Group A (early) were entered in the first trimester (n=35); group B (late) were entered in the late second or early third trimester (n=28). Normal women delivering at the same period were used as controls (n=23). All infants were evaluated by a thorough clinical and echocardiographic examination between 24 and 72 hours of life. Both groups of infants of diabetic mothers had mild increase in mean thickness of ventricular and septal walls compared with those of normal newborn infants, and both had a significant percentage with septal hypertrophy (43% vs 39%). None of the infants in the early group had respiratory symptoms requiring oxygen therapy, compared with 19% in the late group. The early group had significantly fewer infants with elevated right ventricular systolic time interval ratios than did the late group (20% vs 50%); none of the normal infants had elevated ratios. We conclude that careful management of diabetes in pregnancy reduces the severity of hypertrophic cardiomyopathy, although no advantage of early vs late management was obvious. Early management does significantly reduce the number of infants of diabetic mothers who develop respiratory symptoms requiring oxygen therapy.
