Abstrakt:	Objective: To explore the changes of blood coagulative and fibrinolytic systems and functions of pulmonary vascular endothelium in patients with pulmonary thromboembolism (PTE). Methods: Twenty patients with acute massive PTE, 40 patients with acute non-massive PTE and 40 control subjects without PTE were included in the study. D-Dimer (D-D), tissue-type plasminogen activator (t-PA), plasminogen activator inhibitor1 (PAI-1), plasma protein S (Ps), plasma protein C (Pc), thrombomodulin (TM), anticardiolipin antibody (ACA) and homocysteine (Hcy) were measured by the method of ELISA. Antithrombin-III (AT-III) activity was measured by chromo-substrate method. Results: The levels of D-D, t-PA, PAI-1, and TM were (1.46 +/- 0.62) mg/L, (11.4 +/- 6.9) microg/L, (88.2 +/- 27.5) microg/L, (6.8 +/- 1.1) microg/L respectively in patients with acute massive PTE and (0.92 +/- 0.27) mg/L, (6.6 +/- 1.5) microg/L, (60.1 +/- 26.1) microg/L, and (6.30 +/- 1.50) mg/L in patients with acute non-massive PTE. The levels of both PET groups were significantly higher than those of the control subjects [(0.38 +/- 0.10) mg/L, (4.7 +/- 1.4) microg/L, (35.7 +/- 9.2) microg/L, (3.0 +/- 0.5) microg/L and P < 0.05]. The levels of AT-III were (86.0 +/- 11.8)% in patients with acute massive PTE and (90.1 +/- 9.0)% in patients with acute non-massive PTE. The levels of AT-III in both groups were significantly lower than those of the control subjects, which were (102.6 +/- 9.2)% (P < 0.01 and P < 0.05 respectively). The levels of ACA-IgG, IgM and IgA in patients with acute massive PTE and non-massive PTE were also significantly higher than those in the control group (P < 0.05). Conclusion: Imbalance of blood coagulation and fibrolytic systems and pulmonary vascular endothelium damage occur in patients with PTE.
