ABSTRACT

Introduction: Septic shock is a major problem in health care, is the leading cause of death in patients admitted to the Intensive Care Unit.
Ventricular-arterial coupling (VAC) is a way to assess the hemodynamics and myocardial efficiency of the circulatory system. The VAC has been associated with optimal improved survival in patients in shock.
Objective: To analyze the behavior of the VAC and its association with mortality in patients with septic shock.
Method: Patients diagnosed with septic shock and hemodynamic monitoring with pulmonary artery catheter admitted to the Department of Critical Care Medicine of the ABC Medical Center in January 2007 to December 2010.
Results: There were 36 patients in the study. Admission mortality of patients with VAC was 31% and 61% for those without coupling with an OR of 1.9. Mortality at 24 hours was 30% and 75% with and without VAC respectively, with an OR of 2.5, P ≤ 0.05.
Conclusions: Patients who fail to optimize ventricular arterial coupling defined as a ratio Ea/Ees ≤ 1 at 24 hours of treatment have double the mortality
