AbstractBrain natriuretic peptide (BNP) is a diagnostic marker for left ventricular dysfunction. Sepsis and septic shock are increasing in incidence and mortality. Myocardial dysfunction frequently accompanies severe sepsis and septic shock. Although previously described as a preterminal event, ventricular dysfunction with reduced ejection fraction and biventricular dilatation is present in most patients with severe sepsis and septic shock. In survivors, this depression in cardiac function is reversible over the course of seven to ten days. Even though some prognostic factors have been identified in patients with sepsis-induced myocardial dysfunction, their measurement often includes costly and cumbersome techniques. Thus, there is a need for an inexpensive, simple, rapid and readily available marker to predict mortality in septic shock. At present, a relationship between BNP with myocardial dysfunction in septic shock has not been evaluated. However, growing evidence supports the hypothesis that BNP could be an early predictor of mortality in septic shock. If proven, the hypothesis would have important clinical and public health implications.
