[Determination of plasma D-dimer in patients with pregnancy induced hypertension].

OBJECTIVE

To investigate the changes and the clinical significance of plasma D-dimer in normal pregnant women and patients with pregnancy induced hypertension (PIH).

METHODS

Using ELISA method, we measured the level of plasma D-dimer in 160 cases, including 106 normal pregnant women and 25 patients with mild and moderate PIH, 18 patients with preeclampsia and 11 patients with eclampsia.

RESULTS

The value (2.27 +/- 0.92 mg/L) of plasma D-dimer in mild and moderate PIH patients was markedly higher than that of normal third trimester pregnant women (1.45 +/- 0.38 mg/L, P < 0.01). The value (3.09 +/- 1.65 mg/L) of plasma D-dimer in preeclampsia patients was markedly higher than that of mild and moderate PIH patients (P < 0.01). The value (5.62 +/- 1.34 mg/L) of plasma D-dimer in eclampsia patients was markedly higher than that of preeclampsia patients.

CONCLUSION

Determination of plasma D-dimer level in second and third trimester pregnant women was of great significance in diagnosing early PIH and predicting the prognosis of PIH.
