Eligibility
Inclusion criteria
Inclusion criteria: 1. Pregnant women aged 18 and older 2. Fetuses with a gestational age = 32 weeks 3. Suspected of growth restriction defined as an estimated fetal weight or fetal abdominal circumference measured below the 10th population or customized percentile or a change of abdominal circumference <5mm in 2 weeks measured by ultrasound
Exclusion criteria
Exclusion criteria: 1. Born <37 weeks gestational age 2. Known chromosomal and/or structural anomaly 3. Multiple gestation 4. Mothers with cardiac heart disease 5. Mothers’ severe systemic disease 6. Antihypertensive medication 7. Antenatal intra-uterine infection
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Prediction of mean blood pressure (BP) (in mmHg) at one year of age is measured using the average acceleration capacity (bpm), tricuspid annular plane systolic excursion (mm), right sphericity index, Strain-rate, aortic distensibility, isovolumetric relaxation time (ms)) during pregnancy. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Adverse birth outcomes are measured using 1.1. Mortality defined as intra-uterine death or death before hospital discharge 1.2. Acidosis defined as arterial cord blood pH75th centile and/or BP > 95th centile at birth and at 12 months of age 5. Prediction of mean blood pressure (BP) at one year of age (mm Hg) using the following measurements: metabolic profile, fetal functional echocardiographic parameters others than the ones used for primary outcome 6. Correlation of mean blood pressure (BP) at one year of age (mm Hg) and autonomic nervous system [average acceleration and deceleration capacity (bpm)] and antenatal/ fetal functional echocardiographic parameters 7. Correlation of antepartal cardiac function parameters and those at 1 year of life | — |
