  • Title: Marked elevations in N-terminal brain natriuretic peptide levels in septic shock.
    Author: Chua G, Kang-Hoe L.
    Journal: Crit Care; 2004 Aug; 8(4):R248-50. PubMed ID: 15312225.
    Abstract:
    INTRODUCTION: N-terminal pro brain natriuretic peptide (NT-proBNP) is a cardiac biomarker that has recently shown to be of diagnostic value in a diagnosis of decompensated heart failure, acute coronary syndromes and other conditions resulting in myocardial stretch. We sought to study whether sepsis-induced myocardial dilation would result in an elevation of NT-proBNP. METHOD: Serum NT-proBNP measurements were made in six consecutive patients with septic shock within 6 hours of admission to the intensive care unit. RESULTS: Markedly elevated levels of NT-proBNP were found in all six patients. CONCLUSIONS: NT-proBNP levels can be markedly elevated in critically ill patients presenting with septic shock. An elevated NT-proBNP level in a critically ill patient is not specific for decompensated heart failure.
