Abstract:
Objective To observe the value of right ventricle modified myocardial performance index(RV-Mod-MPI)for evaluating maternal obstetric antiphospholipid syndrome(OAPS)involving fetal right ventricular function.Methods Forty-five pregnant women with maternal OAPS(OAPS group)and 60 healthy pregnant women(control group)were prospectively enrolled.Fetal RV-Mod-MPI was obtained with tricuspid and pulmonary valve flow images by applying pulsed wave Doppler(PW).Late pregnancy conditions and data of newborns after delivery were recorded.The indexes were compared between groups.Receiver operating characteristic curve was drawn,and the area under the curve(AUC)was used to assess the efficacy of fetal RV-Mod-MPI for predicting adverse pregnancy outcomes in OAPS group.Results Compared with those in control group,OAPS group had higher fetal RV-Mod-MPI values,lower newborn birth weight and lower Apgar score at 1 min after birth,as well as higher probability of adverse pregnancy outcomes(all P＜0.05).The AUC of fetal RV-Mod-MPI for predicting adverse pregnancy outcome in OAPS group was 0.726.Conclusion RV-Mod-MPI could be used to evaluate maternal OAPS involving fetal right ventricular function and predict adverse pregnancy outcomes.
