摘要
Aim To investigate the changes of modified myocardial performance index (Mod-MPI) in early-onset and late-onset fetal growth restriction (FGR) cases, and its association with adverse perinatal outcome. Methods This was a prospective study on 77 early-onset and 100 late-onset FGR cases. Hundred normal fetuses were matched as control groups for early-onset and late-onset FGR groups, respectively. Mod-MPI and vessel Doppler parameters including umbilical artery (UA), ductus venosus (DV), and middle cerebral artery (MCA) were measured. Perinatal outcomes were followed up. Mod-MPI of FGR cases were compared in normal Doppler, abnormal Doppler, and control groups. The association of Mod-MPI and perinatal outcome was investigated, and further efficacy of Mod-MPI predicting adverse outcome was studied. Results Compared with control groups, both abnormal and normal Doppler groups showed increased Mod-MPI in early-onset and late-onset FGR, respectively. Mod-MPI had no significant difference between abnormal and normal Doppler groups. Mod-MPI was associated with adverse outcome in early-onset FGR (OR = 3.307) and late-onset FGR (OR = 3.412). The sensitivity and specificity of Mod-MPI predicting adverse outcome were 60% and 80% when cutoff value was 0.47 in early-onset FGR. And they were 65% and 70% when cutoff value was 0.50 in late-onset FGR. Conclusion Fetal growth restriction fetuses had increased Mod-MPI. Mod-MPI could be used to predict adverse perinatal outcome of FGR fetuses. Mod-MPI was an effective parameter to supplement vessels' Doppler parameters in monitoring FGR.
