Abstract:
Objective To observe the value of myocardial performance index(MPI)for evaluating fetal left ventricular(LV)function in pregnant women with obstetric antiphospholipid syndrome(OAPS).Methods Totally of 41 singleton pregnancy women with OAPS(criteria-OAPS[C-OAPS]group,n=16;non-criteria OAPS[NC-OAPS]group,n=25)and 60 healthy singleton pregnancy women(control group)were prospectively enrolled.Mitral flow E velocities/A velocities,isovolumic relaxation time(IRT),isovolumic contraction time(ICT),ejection time(ET)and MPI of fetal LV were compared among 3 groups.Receiver operating characteristic(ROC)curve was drawn to evaluate the efficacy of MPI for predicting adverse pregnancy outcomes of pregnant woman.Results Significant differences of mitral flow E velocities/A velocities,IRT,ICT,ET and MPI of fetal LV were found among 3 groups(all P＜0.05).Results of pairwise comparison showed that among C-OAPS group,NC-OAPS group and control group,IRT and MPI of LV decreased,whereas E/A and ET of LV increased in order(all P＜0.05).ICT in C-OAPS group was higher than that in control group(P＜0.05).The sensitivity,specificity and area under the curve of MPI for predicting adverse pregnancy outcomes of pregnant woman with OAPS was 90.00％,64.45％and 0.798,respectively.Conclusion MPI could be used to evaluate fetal LV function in pregnant women with OAPS,also being helpful for predicting adverse pregnancy outcomes.
