Prevalence of Pulmonary Embolism in Patients With Syncope (PESY)

January 22, 2015 updated by: Paolo Prandoni, University of Padova

The Prevalence of Pulmonarym Embolism in Patients With the First Episode of Syncope

All patients consecutively referred with the first episode of transient and short-lasting loss of consciousness will have a diagnostic workup for the assessment of the most common causes of syncope, and will be evaluated for the presence of pulmonary embolism (PE) with the use of an internationally accepted algorithm including a pre-test clinical probability (PTP according to the method of Wells et al.) and a high-sensitivity quantitative D-dimer assay. If the PTP is low and D-dimer negative, PE will be excluded. All other patients will undergo confirmatory diagnostic tests (either computerized tomography or ventilation/perfusion lung scanning) in order to confirm or rule out the presence of PE.
