The effect of coagulation parameters on the placental respiratory and nutritive function in women having chronic hypertension with superimposed preeclampsia

The aim of this study was to explore the relationship between coagulation and fibrinolytic system parameters with nutritive and respiratory placental function. We have analysed 79 pregnant women, of which 39 with severe preeclampsia (index group) and 41 healthy pregnant women. When comparing the study groups in third trimester, significantly lower platelet counts, fibrinogen values and antithrombine III values have been found in the index group compared to the control group. Factor VII levels were not found to be significantly different. The control group revealed significantly higher levels of coagulation factors II, V and VIII, compared to the index group. The increase of FDP, reduction of fibrinogen and increase of fibrinolysis in index group, when compared to the control group of healthy pregnant women, are the reflection of the intravascular fibrin deposition that leads to the described coagulation changes and consecutively to the foetal growth retardation. Indirect evidence are the correlation between newborn's weight and fibrinogen levels/fibrinolytic activity.
