About this study

Official title: Potential Impact of Blood Pressure Variability on Right Ventricular Remodeling in Pregnant Women With Pre-eclampsia or Gestational Hypertension

The goal of this observational study is to learn about the potential effect of blood pressure variability changes on right ventricular strain in pregnant women with gestational hypertension or pre-eclampsia

Read the detailed description

Hypertensive disorders of pregnancy include chronic hypertension, gestational hypertension, pre-eclampsia and chronic hypertension with superimposed pre-eclampsia. Pre-eclampsia, and all hypertensive disorders affect about 5-10% of pregnancies.

The term Blood Pressure Variability is an entity that characterizes the continuous and dynamic fluctuations that occur in blood pressure levels throughout a lifetime.

It encompasses a wide range of blood pressure variations; occurring over seconds or minutes (very short- term BPV), along 24 hours (short- term BPV, usually assessed by ambulatory BP monitoring), and between days (mid- term or day- to- day BPV, assessed with home BP monitoring), Long-term BPV has also been described, including seasonal BP variations and changes between clinic visits over months or years (visit- to- visit BPV).

Studies showed that visit-to-visit BP variability was associated with gestational hypertension and preeclampsia , as well as with risk of adverse birth outcomes in pregnant women without proteinuria or chronic hypertension.

Preeclampsia is a pregnancy-specific disorder that complicates 2-8% of pregnancies worldwide.

Traditionally the condition is diagnosed in the case of de novo development of hypertension (> 140/90 mmHg) and proteinuria during the second half of pregnancy (>20 weeks of gestation).

Preeclampsia (PE) is a life-threatening condition in pregnancy and a major cause of maternal and neonatal morbidity and mortality.

It affects 2-8% of pregnancies that develop serious complications such as eclampsia, hemolysis, elevated liver enzyme levels,thrombocytopenia, and pulmonary edema. These end organ damages usually disappear 12 weeks after delivery.

Gestational hypertension refers to hypertension with onset in the latter part of pregnancy (>20 weeks' gestation) without any other features of preeclampsia, and followed by normalization of the blood pressure postpartum, however, be a harbinger of chronic hypertension later in life as compared with patients who do not have such a history.

There is an association between RV longitudinal strain and functional capacity in hypertensive patients. as well as the strong relationship between RV longitudinal strain and cardiovascular mortality and morbidity in a wide range of cardiovascular conditions.

Over the past few decades, there has been a lot of research done on left ventricular remodeling in hypertensive diseases of pregnancy, especially in gestational hypertension and preeclampsia.However, anatomical, functional, and mechanical changes to the right ventricle are still largely unclear. The limited data are also contradictory because some authors reported significant functional changes in the form of increased RV diameter, elevated pulmonary pressure, and decreased RV longitudinal strain. while other studies showed no difference in RV structure and function between normotensive controls and pregnant women with hypertensive disorders.

In the current study, we are going to assess the impact of gestational hypertension and preeclampsia on RV remodeling. If remodeling occurs, we are going to assess RV recovery post partum.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • EchocardiographyDiagnostic test

    Two-dimensional RV strain imaging will be performed by using three consecutive cardiac cycles of 2D images in the apical four-chamber view to assess RV-GLS

Study groups in NCT06100484
Study groupRoleWhat they receive
Healthy groupPregnant women above 20 weeks of pregnancy with no hypertensive disorders with pregnancy
Receives: Diagnostic Test: Echocardiography
Diseased groupPregnant women above 20 weeks of pregnancy with gestational hypertension or pre-eclampsia
Receives: Diagnostic Test: Echocardiography

What is being measured

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

  1. Number of participants that experienced right ventricular remodeling

    Assessment of right ventricular strain via 2D Echocardiography and Speckle tracking

The record says: finished, as of the sponsor's last update on 6 Aug 2024. 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 Egypt. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Number of participants that experienced right ventricular remodeling (time frame: From Baseline at time of examination till 3 months post-partum). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06100484, which also lists 4 linked publications.

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 6 Aug 2024.
