We conducted a prospective clinical study to investigate the diagnosti
c value of fibronectin levels in patients with pulmonary embolism. 20
consecutive patients who were admitted to an Emergency Care Unit with
pulmonary embolism were enrolled in the study, together with healthy p
ersons as controls. Fibronectin levels were significantly high (p<0.00
1) in patients with pulmonary embolism as compared to the healthy popu
lation. We conclude that fibronectin is a valuable parameter in the di
agnosis of pulmonary embolism.
