To investigate cardiac effects of excess and deficiency of growth hormone (GH) we studied twenty acromegalic subjects and eleven adult patients with GH deficiency by means of a non invasive method, the Doppler echocardiography. The results obtained in the group of patients were compared with those of two groups of twenty and eleven normal subjects, respectively, age and sex matched. The age of the acromegalic patients ranged from 20 to 62 years. Nineteen patients were considered to have active acromegaly at the time of the study. Mean duration of disease since treatment was 12 +/- 5 years (range 5 to 24 years). The age of GH deficient adults ranged from 21 to 33 years. All these patients have been treated with extractive GH over nine years and the therapy withdrawal was performed at least three years before entering the study. In the group of acromegalic patients, a subgroup including nine patients with mild to moderate hypertension was considered. All subjects gave informed consent and the study protocol was approved by the Ethical Committee of the Medical School of Naples. Right ventricular free wall thickness resulted significantly increased in acromegalic patients (8 +/- 2 vs 4 +/- 1 mm; p < 0.001). Left ventricular mass index was augmented both in the whole group and in the subgroups of normotensive and hypertensive acromegalics as compared with normals (134 +/- 33 p < 0.001, 115 +/- 20 p < 0.01 and 156 +/- 31 p < 0.001 vs 80 +/- 18 g.m-2). Ejection phase indices were normal in patient group, while impaired left and right ventricular diastolic filling was found.

Abstract

To investigate cardiac effects of excess and deficiency of growth hormone (GH) we studied twenty acromegalic subjects and eleven adult patients with GH deficiency by means of a non invasive method, the Doppler echocardiography. The results obtained in the group of patients were compared with those of two groups of twenty and eleven normal subjects, respectively, age and sex matched. The age of the acromegalic patients ranged from 20 to 62 years. Nineteen patients were considered to have active acromegaly at the time of the study. Mean duration of disease since treatment was 12 +/- 5 years (range 5 to 24 years). The age of GH deficient adults ranged from 21 to 33 years. All these patients have been treated with extractive GH over nine years and the therapy withdrawal was performed at least three years before entering the study. In the group of acromegalic patients, a subgroup including nine patients with mild to moderate hypertension was considered. All subjects gave informed consent and the study protocol was approved by the Ethical Committee of the Medical School of Naples. Right ventricular free wall thickness resulted significantly increased in acromegalic patients (8 +/- 2 vs 4 +/- 1 mm; p < 0.001). Left ventricular mass index was augmented both in the whole group and in the subgroups of normotensive and hypertensive acromegalics as compared with normals (134 +/- 33 p < 0.001, 115 +/- 20 p < 0.01 and 156 +/- 31 p < 0.001 vs 80 +/- 18 g.m-2). Ejection phase indices were normal in patient group, while impaired left and right ventricular diastolic filling was found.
