Diagnostic utility of N-terminal-proBNP in differentiating acute pulmonary embolism from heart failure in patients with acute dyspnea.
The plasma N-terminal pro-B-type natriuretic peptide (NT-proBNP) level is frequently elevated in dyspnoeic patients and increasingly used in emergency departments to assess the cause of acute dyspnea. In this study we prospectively tested NT-proBNP levels in patients with congestive heart failure (CHF) and/or acute pulmonary embolism (APE) and determined the utility of NT-proBNP for discriminating APE from CHF. ⋯ NT-proBNP can assist in excluding CHF patients from those admitted to the emergency department with acute dyspnea and identifying patients with a high probability of APE, which would reduce the missed diagnosis of APE. Larger studies are necessary to validate these findings.
