Abstract

Cardiac structure and function were evaluated, by means of two- dimensional, M-mode and Doppler echo-cardiograms, in 8 adults with childhood- onset GH deficiency (GHD), before and after six months of GH therapy (0.15 IU/kg/week). Stress test was also performed by means of a modified Bruce protocol with a bicycle ergometer. The data obtained from the patients were compared with those recorded in a sex, age, body mass index (kg/m2, BMI) and exercise matched control group. Before treatment, the means (±SE) intraventricular septal thickness (IVST: 7.1±0.2 mm), LV posterior wall thickness (LVPT: 5.2±0.1 mm), LV mass index (LVM/body surface area, LVMI: 65.1±3.0 g/m2), left ventricular end-diastolic diameter (LVED: 41.4±0.6 mm) and LV ejection time (LVET: 248.7±7.9 msec) of the patients were significantly lower than controls, while PEV/LVET (0.36±0.01) values were significantly higher. LV end-systolic diameter (LVES: 25.5±0.7 mm), LV preejection period (PEP: 88.9±1.1 msec), ejection fraction (EF: 67.8±2.1) and parameters of LV diastolic function (peak E: 67.6±3.4 cm/sec, peak A: 39.1±5.5 cm/sec, E/A ratio: 1.8±0.2) of the patients were similar to controls'. GH treatment significantly increased LVPT (6.8±0.2 mm) and LVMI (80.5±3.5 g/m2) and conversely, reduced PEP (76.9±1.9 msec), LVET (233.7±6.8 msec) and PEP/LVET values (0.32±0.01); no significant changes were observed for the other parameters. The stress test showed a significant improvements in cardiac performance, as demonstrated by the reduction in blood pressure x heart rate product at the same workload (basal: 32722±897.4 vs. after: 25.574.6±439.7, p.
