RESUMO
Estudos recentes usando ecocardiografia convencional e doppler tecidual têm mostrado evidência de disfunção miocárdica em indivíduos com síndrome metabólica. Recentemente, a ecocardiografia bidimensional speckle- racking (2D-STE) emergiu como uma técnica robusta para detectar disfunção ventricular esquerda subclínica por avaliação quantitativa da deformação do miocárdio. Alguns estudos sugerem que a síndrome metabólica está associada com a deformação longitudinal do ventrículo esquerdo e, que o strain longitudinal global medido pela 2D-STE está prejudicado em sujeitos com síndrome metabólica. Pode-se inferir que a identificação precoce da disfunção ventricular esquerda e o reconhecimento do papel dos componentes da síndrome metabólica na alteração da contratilidade miocárdica ajudarão na compreensão e predição de risco de doenças cardiovasculares nessa síndrome.
ABSTRACT
Recent studies using both conventional and tissue Doppler echocardiography have gathered evidence of myocardial dysfunction in individuals with metabolic syndrome. Recently, two-dimensional speckle-tracking echocardiography (2D-STE) has become a robust method for the detection of subclinical left ventricular dysfunction through quantitative assessment of myocardial deformation. Some studies suggest that metabolic syndrome is associated with longitudinal deformation of the left ventricle and that global longitudinal strain measured by 2D-STE is impaired in individuals with metabolic syndrome. It may be inferred that the early identification of subclinical left ventricular dysfunction and the determination of the role of the components of metabolic syndrome in impaired myocardial contractility can help elucidate and predict the risk of cardiovascular diseases in this syndrome.
