Abstract:Objective To study the significance of D-dimer, fibrinogen and myocardial zymogram in gestational diabetes mellitus. Methods Seventy-five patients with GDM prenatal examination and treated in Huai'an women and children's hospital from February 2017 to February 2018 were selected as the study subjects. Another 75 normal pregnant women in our hospital were selected. The differences of serum D-dimer, fibrinogen, myocardial zymogram, pregnancy outcome and fetal status between the two groups were compared. At the same time, the serum D-dimer, fibrinogen, myocardial zymogram, adverse neonatal outcomes and adverse pregnant outcomes were analyzed. Results Serum D-dimer, fibrinogen and myocardial zymogram levels of patients with disease were significantly higher than those of healthy group on pregnancy outcome and fetal status after delivery (P?0.05). The Apgar score of infants was significantly lower than that of healthy group (P?0.05). The incidence of threatened abortion, pregnancy hypertension, postpartum hemorrhage and puerperal infection was significantly higher than that of healthy group (P?0.05), and the incidence of premature birth, death and intrauterine distress syndrome was significantly higher than that of healthy group (P?0.05). The prenatal serum D-dimer, fibrinogen, myocardial zymogram, adverse pregnancy outcomes and adverse neonatal outcomes were positive correlated with neonatal Apgar evaluation. D-dimer, fibrinogen and myocardial enzymes were independent risk factors for adverse pregnant outcomes and neonatal outcomes. Conclusion The adverse pregnancy outcomes of diabetes mellitus patients are positively correlated with serum D-dimer, fibrin and myocardial enzymes. Timely prediction of serum fibrinolytic system and coagulation function and early intervention are of positive significance for the prognosis of patients.
