NT-proBNP as a Tool for the Detection of Acute Pulmonary Artery Embolism (APE)

July 4, 2012 updated by: Claus-Martin Muth, University of Ulm

NT-proBNP: a Useful Tool for the Detection of Acute Pulmonary Artery Embolism in Post-surgical Patients

In patients with suspected APE (Acute Pulmonary Embolism) referred to the intensive care unit (ICU)after major surgery, serum NT-proBNP (N-terminal proBNP), Troponin-I and D-dimers were measured according to the standard hospital protocol. To definitively confirm or exclude APE, all patients underwent an angiographic CT-scan of the thorax.

Study Overview

Detailed Description

In patients with suspected APE referred to the intensive care unit after major surgery, serum NT-proBNP, Troponin-I and D-dimers were measured according to the standard hospital protocol. Blood samples were obtained within one hour after the onset of clinical symptoms.

Definitive confirmation or exclusion of APE was performed with an angiographic CT-scan of the thorax.
