At present, myocardial depression (MD) in septic shock (SS) is more frequently recognized. In 1984, Parker et al. published 20 patients with SS where 50% of them showed a left ventricular ejection fraction (LVEF) less than 40% 1 . It was not until 2006 that it became more widely accepted that some degree of MD was present in this kind of patients 2 . However, the prevalence has been variable depending on the evaluation method, either through cardiac output (CO), measurement of troponins, B type Natriuretic Peptide or by echocardiography 2-4 . In 2008 Vieillard-Baron et al. studied 67 patients with SS without a history of heart disease with transesophageal echocardiography. They estimated a mean incidence of MD greater than 60%, which manifests itself in the first 48 hours of evolution and recovers between seven and ten days after the onset of SS 5 .
