ABSTRACT

The patient was a male with myasthenia gravis, hospitalized with acute respiratory failure due to decompensation of the underlying disease. He evolved with findings suggestive of acute myocardial infarction, with electrocardiographic and enzymatic alterations compatible with that diagnosis. The patient underwent emergency coronary angiography, which showed no severe coronary obstruction, although his left ventricle had significant systolic dysfunction with characteristic alterations, on ventriculography, of the syndrome described as transient ventricular dysfunction or Takotsubo syndrome. On evolution, complete recovery of the electrocardiographic alterations and systolic ventricular function assessed on echocardiography occurred, confirming the syndrome.

ABSTRACT

Homem portador de miastenia gravis, internado por descompensação da doença de base, em insuficiência respiratória aguda. Na evolução, apresentou quadro sugestivo de infarto agudo do miocárdio, com alterações eletrocardiográficas e enzimáticas compatíveis com o diagnóstico. Submetido a coronariografia de urgência, não evidenciou obstrução coronariana grave, entretanto o ventrículo esquerdo apresentava disfunção sistólica importante, com alteração característica pela ventriculografia da síndrome descrita como disfunção ventricular transitória ou síndrome de Takotsubo. Na evolução, houve completa recuperação das alterações eletrocardiográficas e da função ventricular sistólica avaliada pelo ecocardiograma, confirmando a síndrome.
