Dysfunction of the vascular endothelium (ET) causes an increase in serum ET-1 concentration, as observed in septic patients. It was assumed that in this patient population the ET-1 level correlates with the degree of sepsis severity, including the level of organ dysfunction and, in particular, the level of circulatory dysfunction. The aim of the present study was to assess the relationship between levels of ET-1 and levels of N-terminal brain natriuretic propeptide (NT-proBNP), procalcitonin (PCT), and C-reactive protein (CRP), as well as the Sepsis-related Organ Failure Assessment (SOFA) score in septic patients. ⋯ Correlation between the ET-1 levels and SOFA score was .470 (P < .001). Six patients (30%) died during the observation period of 28 days. ET-1 levels correlate with levels of NT-proBNP, PCT, and CRP, as well as the SOFA score in septic patients.
