Abstract
Introduction: Central venous oxygen saturation (ScvO2) provides an estimate of body oxygen consumption/delivery ratio. It has been widely used for optimization of therapy in septic patients; however its value in severe heart failure / cardiogenic shock has not yet been established. Objectives: We aimed to evaluate ScvO2 as a prognostic indicator and as a diagnostic tool to guide therapy in patients with severe heart failure/cardiogenic shock. Conclusion: In patients admitted with severe heart failure/cardiogenic shock requiring inotropic support ± vasopressors, ScvO2 less than 66% despite optimal treatment is a marker of poor outcome and might be an indicator for considering more aggressive therapy
