Increased thrombin generation as a potential marker for adverse pregnancy outcomes

Aim. To estimate the effectiveness of the thrombin generation assay (TGA) in identifying high thrombogenic risk in pregnant women. Material and methods. The study comprised 30 healthy non-pregnant women (control group) and 32 women in the third trimester of pregnancy. Of the latter group, 22 women with complicated pregnancy comprised the study group while the remaining ten women made up the comparison group. After delivery, the patients in the study group were divided into subgroups with a favorable (n = 15) and adverse (n = 7) pregnancy outcomes. The state of the hemostatic system was examined using standard coagulation tests and TGA. Results. Thrombin generation assessed as endogenous thrombin potential (ETP), was statistically significantly higher in pregnant than in non-pregnant women (2300 ± 400 vs. 1700 ± 400, respectively, p <0.005). The patients with adverse pregnancy outcomes had statistically significantly higher ETP compared with women with favorable outcomes (2700 ± 600 vs.
