In view of the high prevalence of cardiac disorders in the intensive care unit the experience of elevated natriuretic peptide levels in the critically ill might be of enormous diagnostic and therapeutic value. BNP and NT-proBNP levels rise to different degrees in critical illness and may also serve as markers of severity and prognosis in diseases beyond acute or chronic heart failure. The diagnostic and prognostic use of natriuretic peptides in the intensive care setting for patients with various forms of shock could be an attractive alternative as noninvasive markers of cardiac dysfunction that could obviate the need for pulmonary artery catheterization in some patients. In a recent issue of Critical Care Januzzi and coworkers 1 report the results of a prospective cohort study evaluating natriuretic peptides in various shock patients in the intensive care unit ICU . The authors found no correlation between elevated levels of amino-terminal pro-BNP NT-proBNP and high filling pressures among patients with shock within the ICU but higher values were
