The peptide measurement should not be used as a replacement for other forms of monitoring and performs best as a diagnostic test when interpreted together with other clinical findings and investigations. At a cutoff value similar to that found in other clinical studies in acute decompensated heart failure measurement of N-terminal pro-B-type natriuretic peptide offers an additional tool for diagnostic assessment of patients presenting to the intensive care physician. Measurement of the B-type natriuretic peptide BNP and mesurement of the N-terminal portion of the prohormone N-terminal pro-B-type natriuretic peptide NTproBNP are part of the routine assessment of patients presenting with acute dyspnoea. The measurement of BNP NTproBNP is now included in the recommendations from professional societies. Coquet and colleagues 1 have studied NTproBNP measurement in the critical care population. They compared the diagnostic performance of NTproBNP using a final diagnosis of cardiac dysfunction based on a combination of clinical and echocardiographic criteria. Using this diagnosis as the dichotomous variable the authors performed receiver operating characteristic curve analysis and showed that the area .
