BACKGROUND: Growth hormone (HGH) replacement during childhood has been shown to increase stature; however, there is little information on its long-term effect on the heart is not yet clear. The aim of this study was to assess cardiac size and function in patients with childhood-onset HGH deficiency in whom HGH treatment had been stopped at the achievement of final height and the effect of a second course of HGH replacement in adult age. METHODS: Cardiac dimensions and function, obtained with echocardiography, of 21 patients (5 women and 16 men, mean age 28 +/- 8 years), all of whom were treated during childhood, were compared with 21 age- and sex-matched healthy control subjects. Eight of these patients (2 women and 6 men, mean age 28 +/- 8 years) were given a second course of GH replacement therapy for 15 +/- 3 months. RESULTS: The stature and all cardiac dimensions of patients with HGH deficiency who were treated during childhood were significantly smaller than those of the control subjects. After the second course of HGH in adulthood, the only significant change observed was an increase in left ventricular (LV) mass (93 +/- 21 vs 106 +/- 24 g, P =.007) and LV mass index (59 +/- 12 vs 66 +/- 13 g/body surface area, P =.005). CONCLUSION: The stature and cardiac dimensions of patients with childhood-onset HGH deficiency measured in adult age were smaller than those of control subjects, despite long-term HGH replacement therapy during childhood. A second course of HGH treatment during adulthood caused a significant increase in the estimated LV mass index in patients with both isolated and multiple pituitary hormone deficiency.
