Insights
Preeclampsia (PE) patients exhibit altered coagulation, with lower clotting factors and platelet counts, and higher fibrinolysis markers. Postpartum day 1 shows a pro-hemorrhagic state, increasing risks for mothers.
Area of Science:
- Obstetrics and Gynecology
- Hematology
- Perinatal Medicine
Background:
- Preeclampsia (PE) is a serious pregnancy complication.
- Dynamic changes in coagulation function during the perinatal period in PE are not fully understood.
- Understanding these changes is crucial for managing PE-related risks.
Purpose of the Study:
- To investigate the dynamic changes in coagulation function in patients with preeclampsia (PE) during the perinatal period.
- To compare coagulation profiles of PE patients with healthy pregnant women.
- To identify coagulation patterns associated with increased risk of adverse outcomes in PE.
Main Methods:
- Prospective study involving 290 PE patients and 256 healthy pregnant women.
- Coagulation indexes including PT, APTT, TT, FIB, PLT, MPV, PCT, DD, FDP, and MA were measured.
- Data collected during the prenatal period and at 1 and 3 days postpartum.
Main Results:
- PE patients showed decreased PT, FIB, PLT, MPV, PCT, MA, and CI, with increased APTT, TT, DD, PDW, and K values pre-delivery compared to controls.
- Postpartum day 1 in PE patients revealed lower APTT and FIB, and higher TT, DD, and FDP compared to prenatal and postpartum day 3.
- PCT and MPV were highest prenatally in PE patients.
Conclusions:
- PE patients exhibit a state of relative hypocoagulation and hyperfibrinolysis on postpartum day 1.
- This altered coagulation state increases the risk of postpartum hemorrhage and other adverse outcomes.
- Dynamic monitoring of coagulation function is essential for managing PE patients.
Abstract:
To study the dynamic changes in perinatal coagulation function in patients with preeclampsia (PE).The general data and coagulation indexes of 290 PE patients during the perinatal period (prenatal and 1 and 3 days postpartum) and 256 healthy pregnant women in the third trimester of pregnancy were investigated, and the data were analyzed.Compared with healthy pregnant women, prothrombin time (PT), fibrinogen (FIB), platelet count (PLT), mean platelet volume (MPV), thrombocytocrit (PCT), maximum amplitude (MA), and coagulation index (CI) of PE patients decreased, and activated partial thrombin time (APTT), thrombin time (TT), D-dimer (DD), platelet distribution width (PDW) and K values increased before delivery (P < .05). APTT and FIB in PE patients were lower in the day 1 postpartum group than in the prenatal and postpartum day 3 groups, and TT, DD, and fibrin degradation products (FDP) were higher (P < .05). PCT and MPV were highest in the prenatal group (P < .05).Compared with that of healthy pregnant women, the coagulation function of PE patients is in a relatively low-coagulation and high-fibrinolysis state on postpartum day 1, which increases the risk of postpartum hemorrhage and other adverse outcomes.

Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which...
