Abstract

This pilot study assessed the urinary fibrinopeptide A (uFPA) levels and the combination of uFPA test plus ventilation/perfusion (V/Q) scan in the diagnostic evaluation of acute pulmonary embolism (PE). One hundred consecutive patients were studied prospectively. Twenty-nine patients fulfilled diagnostic criteria defined in this study (seven with and 22 without PE). The uFPA concentration was significantly higher in patients with than without PE (41.1±2.6 vs 4.8±2.5 ng/mg of creatinine, p<0.0001). In all patients with PE, the uFPA levels were higher than threshold value derived by adding 2 standard deviations to the mean uFPA concentration of patients without PE. In patients without PE, the V/Q scan was negative in 16, the uFPA test was negative in 18, and at least one of the tests was negative in 21. These preliminary data suggest that a negative uFPA test may be helpful in excluding PE and that uFPA in combination with V/Q lung scans may correctly exclude PE in more patients than either test alone. Further studies in a large unselected population are needed to confirm these results.
