Cardiac Mass and Function, Carotid Artery Intima-Media Thickness, and Lipoprotein Levels in Growth Hormone-Deficient Adolescents

The objective of our study was to evaluate whether cardiac mass and function, carotid artery intima-media thickness, and serum lipid and lipoprotein(a) levels are abnormal in adolescents with GH deficiency. Young adults with childhood-onset and adulthood-onset GH deficiency have been found to have a higher cardiovascular risk, as manifested among other factors by reduced left ventricular mass, impaired systolic function, significant increase in arterial intima-media thickness, and dyslipidemia. Twelve adolescents (seven males and five females) with GH deficiency (10 idiopathic and 2 organic), with an age of 14.2 ± 2.8 yr and a height of 140.6 ± 17.9 cm (height sd score,− 2.6 ± 0.3), were studied. Six children had received GH in the past but were off therapy for several years, whereas six patients had never been treated with GH. Fasting blood samples were obtained for serum lipids and lipoprotein(a) analysis. Patients underwent transthoracic M-mode and two-dimensional echocardiographic evaluation for measu...
