Background: B-type natriuretic peptide (BNP) is secreted in response to myocardial stretch and has been used clinically to assess volume overload and predict death in congestive heart failure. More recently, BNP elevation has been demonstrated with septic shock and is predictive of death. How BNP levels relate to cardiac function in sepsis remains to be established. Study Design: Retrospective review of prospectively gathered sepsis database from a surgical ICU in a tertiary academic hospital. Initial BNP levels, patient demographics, baseline central venous pressure levels, and in-hospital mortality were obtained. Transthoracic echocardiography was performed during initial resuscitation per protocol. Results: During 24 months ending in September 2009, two hundred and thirty-one patients (59 ± 3 years of age, 43% male) were treated for sepsis. Baseline BNP increased with initial sepsis severity (ie, sepsis vs severe sepsis vs septic shock, by ANOVA; p < 0.05) and was higher in those who died vs those who lived (by Fisher's exact test; p < 0.05). Of these patients, 153 (66%) had early echocardiography. Low ejection fraction (
