Clinical value of fetal heart quantitative analysis technology for the assessment of fetal heart morphology and function in hypertensive disorder complicating pregnancy
Objective To explore the clinical application value of fetal heart quantitative analysis technology(fetal HQ)in evaluating the fetal heart morphology and function in hypertensive disorder complicating pregnancy(HDCP).Methods A total of 49 pregnant women with HDCP(HDCP group)who gave birth in the Shanxi Maternal and Child Health Hospital,as well as 52 healthy pregnant women without underlying diseases or pregnancy complications during the same period and no abnormal results on routine prenatal ultrasound examinations of fetuses(control group)were selected.The fetal HQ was used to obtain the end-diastolic global sphericity index(GSI)and ventricular area change fraction(FAC),the Z-scores of 24 segments short axis shortening rate(FS)and 24 segments sphericity index(SI)in the four chamber view of the left and right ventricles,and the differences of above parameters between the two groups were compared.Results There were statistically significant differences in GSI and left and right ventricular FAC between HDCP group and control group(all P<0.05).There were statistically significant differences in Z-scores of left ventricular FS at 2～24 segment between HDCP group and control group(all P<0.05),while there was no statistically significant differences in Z-score of left ventricular FS at 1 segment between HDCP group and control group.There were significant differences in the Z-score of right ventricular FS at 1～24 segment between HDCP group and control group(all P<0.05).There were statistically significant differences in left ventricular at 2～16 segment between HDCP group and control group(all P<0.05),while there were no statistically significant differences in left ventricular SI at 1,17～24 segment and right ventricular at 1～24 segment between HDCP group and control group.There was statistically significant difference in left and right ventricular SI at 1～11 segment in HDCP group(all P<0.05),while there were no statistically significant difference at 12～24 segment.There were statistically significant in left and right ventricular SI at 1～15 segment,22～24 segment in control group(all P<0.05),while there were no statistically significant difference at 16～21 segment.Conclusion fetal HQ can be used to evaluate the fetal heart morphology and function in HDCP,which has a certain clinical application value.
