Active clinical trials for "Hypertension, Pregnancy-Induced"

The aim of this study is to evaluate the impact of personalized postpartum follow-up cards on completion of postpartum health related tasks. The intervention will consist of a card given to patients at time of discharge. One side of the card will list the patient's name and a list of recommended postpartum follow-up appointments based on their diagnoses at the time of discharge. Participants will be randomized to this intervention or the control group, which will consist of standard education routinely given at discharge. The primary endpoint will be the rate of completion of a postpartum blood pressure check or two hour glucose tolerance test, or both, depending on the patient's discharge diagnosis within the first year after discharge. The secondary endpoints will include establishing care with a primary care provider within the first year after delivery, or completion of postpartum pap smear or colposcopy, as indicated.

The goal of this project is thoroughly evaluate the added value of telemonitoring (TM) program for women at risk for gestational hypertensive disorders (GHD), by investigating it impact on prenatal follow-up, health outcomes for mother and child, costs and satisfaction, and by specifically investigating what are the major contributors to this added value. A substudy (CAPROM) will be conducted at the Department of Obstetrics & Gynecology at Ziekenhuis Oost-Limburg (ZOL) in collaboration with the Department of Physiology of Hasselt University in the framework of the Limburg Clinical Research Center (LCRC). CAPROM aims at evaluating the relationship between longitudinal (clinical) blood pressure measurements and changes in (subclinical) cardiovascular (CV) hemodynamics throughout pregnancy, as well as their responses to antihypertensive medication. To this end, CV profiling will be performed longitudinally on pregnant women at risk for developing GHD being included in the TM group of the PREMOM II study (group 1) or being followed-up via TM as part of their usual care (group 2). A separate ICF is signed for inclusion in the CAPROM substudy. The results of the CAPROM study will be performed by a researcher who is not involved in the PREMOM II main study. In addition, results of the CV profiling will not be communicated to the clinical decision makers of PREMOM II.

Investigators propose a comprehensive management program for postpartum patients with HDP who are at risk for severe maternal morbidity and mortality. Our program will emphasize three key components: 1) self-monitoring of blood pressures with app-based reporting connected to our electronic health record, 2) blood pressure management directed by a program navigator with guideline and physician support and 3) facilitated transitions of care to primary care clinicians for hypertension management. Investigators will randomize 300 patents with HDP on postpartum day one with follow up through 3 months postpartum. Primary outcome will be blood pressure reporting at 7-10 postpartum. Secondary outcomes include blood pressure control at 7-10 days postpartum, identification and treatment of severe blood pressures, severe maternal morbidity, hospital readmission, triage visits for hypertension, postpartum and primary care visit attendance, and multiple patient-reported outcome measures. All outcomes will be stratified by race (Black and non-Black) to evaluate disparities and by tight versus usual blood pressure control to evaluate the impact of strict postpartum blood pressure control on outcomes. Investigators hypothesize that a comprehensive postpartum HDP management program will improve hypertension control for all patients and reduce disparities that affect Black patients, and that stricter blood pressure control will be associated with fewer adverse outcomes.

Hypertensive disorder complicating pregnancy is a set of diseases of pregnancy coexisting with elevated blood pressure. The incidence of it is approximately 5-12%. Pregnancy-induced hypertension is a pregnancy-specific disorder, severely impairing both maternal and fetal health, and the major cause of maternal and perinatal mortality rate increased. But so far, the specific etiology is still unclear. Recently, fibroblast growth factor 23 (FGF23) has emerged as key endocrine regulators of the metabolism of vitamin D and calcium and phosphorus by combining FGFR-α- Klotho receptor complex. Current studies showed that α- Klotho involved the development of gestational hypertension via the production of endothelial nitric oxide, angiogenesis, and the formation of antioxidant enzymes. On the other hand, vitamin D deficiency during pregnancy has an adverse impact on maternal and fetal health, including gestational hypertension. Therefore, the relationship of the expression of FGF23 and the development of gestational hypertension has attracted the attention of relevant scholars. The aim of this study is to detect the difference of the expression of FGF23 between the hypertensive women and normal pregnant women.

To compare the cardiovascular profile of pre-conceptional women at risk for developing Gestational Hypertensive Disorders in subsequent pregnancy before and after physical activity.

Preeclampsia is a multi-system vascular disease which affects 2-5% of pregnancies. It is also a risk factor for the development of cardiovascular disease later in life and a number of functional and structural cardiac changes have been found in this population of patients. In mouse models disruption of a group of immune cells, neutrophils, has led to alteration of the placenta and offspring consistent with those seen in preeclampsia. These mice also have an abnormal cardiac function and structure (Nadkarni et al 2016). The investigators hypothesis that this may also occur in humans. This study aims to intimately link the maternal immunological and vascular components of cardiac dysfunction in women preeclampsia. The investigators hypothesise that in preeclampsia activated neutrophils may affect maternal immune system thus leading to myocardial injury and altered cardiac function. The study intends to identify the mechanisms by which the maternal immune system (focusing on neutrophil and T-cell subsets) affects cardiac function in women with preeclampsia. Specific aims to be addressed are: Aim 1: To correlate specific neutrophil phenotype(s) and function to cardiac function in women with preeclampsia during pregnancy Aim 2: To test whether specific activated neutrophil phenotype persists postpartum and whether this neutrophil phenotype correlates with cardiac function in women with preeclampsia postpartum The study population will comprise of 3 groups: Normotensive pregnant (~33 patients) Pregnancy-induced hypertension (PIH; New-onset hypertension after 20 weeks without proteinuria; ~33 patients) Preeclampsia (~34 patients) Cardiac function will be evaluated using cardiovascular magnetic resonance, echocardiography and cardiac markers in the blood. The participants immune system will be assessed from blood samples looking at the immune cells, hormone levels and inflammatory and non-inflammatory mediators. The secondary research objective is to investigate whether changes in the immune system and cardiac function in participants is persistent after delivery. Therefore participants will have scans and blood tests both antenatally and at 3 months postnatally. By identifying key changes in immune cell type and function with cardiac abnormalities in women with preeclampsia, data obtained from this study could provide novel insight into how the maternal immune system influences cardiac changes in normal and preeclamptic pregnancies. Identifying such links could pave the way for future therapeutic targets.

This prospective observational trial includes women with high risk pregnancies complicated with hyperglycemia in pregnancy and excessive body weight. The participants are enrolled when pregnant and monitored throughout pregnancy and delivery until the offspring is 6 months old. This research addresses the question which risk factors for non-communicable disorders such as hypertension, obesity, type 2 diabetes for a woman and her offspring can be detected during pregnancy and in early childhood.

Research Question How does maternal blood pressure respond in the postpartum period for women who had a hypertensive disorder in pregnancy? Aim To evaluate the recovery of maternal blood pressure after a pregnancy affected by new onset hypertension after twenty weeks gestation Objectives To identify rates of persistent hypertension after pregnancies affected by HDP To assess and compare the accuracy of HBPM against the gold standard of ABPM To assess the maternal acceptance of HBPM and ABPM To explore what CVD-related care information is provided at the 6-8 week GP appointment
