RESUMO
A função sistólica ventricular esquerda global é um dos mais importantes aspectos que determinam os desfechos dos pacientes com infarto do miocárdio. Aqueles com má função sistólica ventricular têm o maior potencial de se beneficiarem com a revascularização, desde que tenham miocárdio viável. O presente artigo foi escrito para rever as técnicas de imagens disponíveis e capazes de prover o cardiologista, no que se refere aos pacientes com infarto do miocárdio suspeitado ou confirmado, de um diagnóstico acurado do miocárdio viável residual. O principal objetivo desta publicação é chamar a atenção para o papel da ecocardiografia de estresse com os diferentes agentes farmacológicos empregados na arena clínica da isquemia miocárdica, com o fim de se demonstrar a presença do miocárdio viável.
ABSTRACT
Global left ventricular systolic function is a major determinant of outcome in patients with myocardial infarction. Patients with poor ventricular systolic function have the greatest potential to benefit from revascularization, provided they have viable myocardium. The present article was written to review the current imaging techniques that are able to help the clinician accurately diagnosis the residual viable myocardium, with regard to patients with suspected or confirmed myocardial infarction. The mean aim of this paper was to highlight the usefulness of stress echocardiography with the different available agents in the clinical arena of myocardial ischemia to demonstrate the presence of viable myocardium.
