[Cardiac morphology and performance alterations and analysis of determinant factors of left ventricular hypertrophy in 40 patients with acromegaly].
Acromegaly has a high mortality rate due mainly to cardiovascular complications. The aim was to evaluate the determinant factors of left ventricular hypertrophy (LVH) and cardiac alterations in 40 acromegalic patients submitted to clinical-laboratorial studies and echocardiogram. The variables analyzed were age, sex, disease duration, arterial hypertension (AH), impaired glucose tolerance/DM, previous treatment with octreotide, GH and %IGF-I. Univaried analysis showed that patients with LVH were older (p= 0.031), had higher prevalence of AH (p= 0.009) and higher %IGF-I (p= 0.002), than those without LVH. Multivaried analysis showed AH and %IGF-I as determinants of LVH (p= 0.035 and p= 0.016). After dichotomizing of %IGF-I, a score was created and the frequency of LVH was 9%, 65%, 92% x 0, 1, 2; p< 0.0001. Prevalence of aortic ectasia was higher and valvar disease was smaller than reported in the literature. We conclude that AH and %IGF-I were determinants of LVH.
