RESUMO
Resumo Fundamento Embora se saiba que a fração de ejeção (FE) do ventrículo esquerdo (VE) medida por eletrocardiograma seja preservada em pacientes com acromegalia, não há informação suficiente sobre deformação longitudinal global e deformação do átrio esquerdo (SLG-VE e SAE). Objetivo O objetivo deste estudo foi avaliar as funções do ventrículo esquerdo (VE) e do átrio esquerdo (AE) por ecocardiograma strain (ES) em pacientes com acromegalia. Métodos Este estudo incluiu 50 pacientes com acromegalia na forma ativa da doença e 50 controles saudáveis com idade, sexo e área de superfície corporal similares. Além dos ecocardiogramas de rotina, medições de SLG-VE e SAE foram realizadas com o ES. Resultados Os valores dos SAE e SLG-VE foram significativamente mais baixos em pacientes com acromegalia (p<0,05 para todos). Na análise bivariada, a pressão arterial sistólica, o pró-hormônio N-terminal do peptídeo natriurético cerebral, o fator de crescimento semelhante à insulina tipo 1, e detectou-se que os níveis de IMVE tinham correlação positiva com SAE e SLG-VE (p<0,05). O nível de IGF-1 tinha forte correlação com SAE e SLG-VE (p<0,001 e β=0,5 vs. p<0,001 e β=0,626, respectivamente); 48% dos pacientes com acromegalia têm SLG-VE reduzido (<20%). O índice de massa do ventrículo esquerdo (IMVE) determina independentemente a presença de SLG-VE reduzido, e cada 1g/m2 de aumento no nível de IMVE aumenta a probabilidade de redução de SLG-VE em 6%. Conclusão Embora a fração de ejeção de VE seja normal em pacientes com acromegalia, os valores de SAE e SLG-VE são significativamente mais baixos. Além do aumento em IMVE, outro achado do envolvimento cardíaco pode ser a redução de SAE e SLG-VE. Portanto, além do ecocardiograma de rotina, SAE e SLG-VE podem ser úteis para avaliar os sinais iniciais de envolvimento cardíaco antes da ocorrência de alterações cardíacas irreversíveis.
ABSTRACT
Abstract Background Although it is known that the left ventricular (LV) ejection fraction (EF) measured by echocardiography is preserved in patients with acromegaly, there is not enough information about the LV and left atrial strain (LV-GLS and LAS). Objective This study aimed to evaluate the left ventricular (LV) and left atrial (LA) functions with strain echocardiography (SE) in patients with acromegaly. Methods This study included 50 acromegaly patients with active disease and 50 healthy controls with similar age, gender, and body surface area. In addition to routine echocardiography examinations, LV-GLS and LAS measurements were performed with SE. Results LAS and LV-GLS values were significantly lower in patients with acromegaly (p<0.05 for all). In bivariate analysis, systolic blood pressure, N-terminal prohormone of brain natriuretic peptide, Insulin-like growth factor-1, LA diastolic diameter, and LVMI levels were found to be positively correlated with both LAS and LV-GLS (p <0.05). IGF-1 level was strongly correlated with LAS and LV-GLS (p<0.001 and β=0.5 vs. p<0.001 and β=0.626, respectively); 48% of patients with acromegaly have reduced LV-GLS (<20%). Left ventricular mass-index (LVMI) independently determines the presence of reduced LV-GLS and each 1g/m2increase in LVMI level increases the likelihood of reduced LV-GLS by 6%. Conclusion Although LV ejection fraction is normal in patients with acromegaly, LAS and LV-GLS values were significantly reduced. Apart from LVMI increase, another finding of cardiac involvement may be LAS and LV-GLS decrease. Therefore, in addition to routine echocardiography, LAS and LV-GLS may be useful to evaluate early signs of cardiac involvement before the occurrence of irreversible cardiac changes.
