Objective To investigate the difference in fibrinogen and D-dimer (D-D) level among pulmonary embolism patients with different risk stratification. Methods Sixty pulmonary embolism patients admitted during January 2013 and January 2014 in our hospital were retrospectively analyzed.The general clinical data were gathered, and the patients were divided into a high-risk group (n=19), a moderate-risk group (n=21), and a low-risk group (n=20) according to the 2008 ESC Guidelines on the diagnosis and management of acute pulmonary embolism.Fourteen patients admitted simultaneously with dyspnea and chest pain without pulmonary embolism were randomly recruited as a control group.The plasma levels of fibrinogen and D-D were detected and compared between these groups. Results In the pulmonary embolism patients, there were no significant statistical differences in general data between the patients with different risk degree.With the risk degree increased, the level of fibrinogen decreased and the level of D-D increased (P < 0.05).Compared with the pulmonary embolism patients, the level of fibrinogen was higher and the level of D-D was lower in the control group(P < 0.05).The level of fibrinogen was negatively correlated with the level of D-D with a correlation coefficient of-0.805. Conclusions Elevated fibrinogen is one of high risk factors of the pulmonary embolism. With the occurrence of pulmonary embolism, the level of fibrinogen becomes lower, suggesting the potential of fibrinogen as a indicator for pulmonary embolism diagnosis and risk stratification.
