Infarto de miocardio con coronarias sanas. Un desafío para el clínico

We report a case of a patient with cardiorespiratory arrest due to recovered ventricular fibrillation. In the acute phase, ST segment elevation was observed in anterolateral wall in the electrocardiogram, and severe left ventricular dysfunction was observed on the echocardiogram. However, an urgent cardiac catheterization didńt shown the existence of coronary lesions despite of the severe ventricular dysfunction. At six days there was a complete recovery of ventricular function and echocardiographic alterations and successive electrocardiographic records were also normalized. The peculiarity of the present clinical case is the rapid favorable evolution after the recovery of a sudden death, as well as the diagnostic, prognostic and therapeutic questions it propose.
