About this study

Official title: Fetal Growth and Pregnancy Complications Among Women With Heart Disease in Norway: a Cohort Study

An increasing proportion of women with heart disease now go through pregnancy and childbirth. More knowledge about the risk of complications and adverse outcomes for the mother and the baby is needed to guide clinical care in this diverse patient group.

The purpose of this study is to, in a cohort of pregnant women with heart disease;

  • determine fetal growth, and risk of fetal growth restriction and preterm birth
  • determine whether maternal blood biomarkers are associated with development of preeclampsia, the time of delivery and maternal and perinatal adverse outcomes
  • determine the risk of hypertensive pregnancy complications

The expected outcome of the project is to increase the knowledge of optimal diagnosis and treatment of women with heart disease that go through pregnancy to be able to improve clinical care and the outcomes for mother and baby.

Read the detailed description

Heart disease is about to become the most important cause of maternal deaths in industrialized countries. In addition, heart disease in pregnancy is associated to an increased rate of fetal growth restriction, premature birth, preeclampsia and other pregnancy complications for the mother and the baby. As many women with congenital or acquired heart disease now go through pregnancy and childbirth, more knowledge about the risk of complications and adverse outcomes for the mother and the baby is needed to guide clinical care in this diverse patient group.

The National Unit for Pregnancy and Heart Disease is located at Oslo University Hospital, Rikshospitalet, and receive moderate and high risk pregnant women as referrals from hospitals nationwide for follow-up and treatment. The unit has established Oslo University Hospital Register for Pregnancy and Heart disease; a quality register for maternal and fetal outcome in women with heart disease.

The purpose of this study was therefore to, in a cohort of pregnant women with heart disease;

  • determine fetal growth, and risk of fetal growth restriction and preterm birth
  • determine whether maternal blood biomarkers are associated with development of preeclampsia, the time of delivery and maternal and perinatal adverse outcomes
  • determine the risk of hypertensive pregnancy complications

By the next two years, 150 patients will be included in two prospective longitudinal studies. In the first study fetal growth and utero-placental-fetal blood flow will be assessed by serial measurements at specific gestational ages. The mother's cardiac function will also be measured. Primary outcome is fetal growth curve and wellbeing at birth.

In the second study, biomarkers in maternal serum will be measured during the last half of pregnancy to assess if angiogenetic factors are prognostic for the risk of hypertensive complications.

In the last study the researchers will use retrospective data from the Oslo University Hospital Register for Pregnancy and Heart disease to determine the association between heart disease and hypertensive complications in a retrospective cohort of approximately 800 patients.

The expected outcome of the project is to increase the knowledge of optimal diagnosis and treatment of women with heart disease that go through pregnancy to be able to improve clinical care and the outcomes for mother and baby.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Fetal growth

    Serial measurements of fetal biometry

    Measured: From gestational week 12 until time of birth of baby

  2. Occurrence of hypertension/preeclampsia in pregnancy or postpartum

    Diagnosis in index pregnancy or postpartum until discharge from maternity unit

    Measured: From time of study inclusion until time of discharge from maternity unit after birth of baby

  3. Fetoplacental circulation

    Serial measurements of fetoplacental circulation

    Measured: From gestational week 12 until time of birth of baby

Questions about this trial

What is this clinical trial studying?

An observational study of Congenital Heart Disease and Pregnancy Complications, run by Oslo University Hospital at 1 site in Norway.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 5 Sep 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Norway. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Ingvil K Sørbye, PhD, MD (+4723070000 ext. 70228, isorbye@ous-hf.no), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Fetal growth (time frame: From gestational week 12 until time of birth of baby). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 5 Sep 2018.
