Active clinical trials for "Hypertension"

The specific aims of this research study are to Engage participants with poorly controlled hypertension and medication non-adherence to use simple digital approaches, specifically recurring text-messages to improve medication adherence. Promote participant medication adherence and interaction with telehealth platforms with recurring text reminders on medication schedules and refills, science-based hypertension education content, and communication exchange with their health providers to improve blood pressure. Evaluate the role of social support in helping participants manage their hypertension and control of Cardiovascular disease (CVD) risk factors, including daily blood pressure measurement, changes in participant quality of life, and barriers towards medication adherence, and setting goals for health behaviors.

High sodium intake is a significant risk factor for hypertension. Recently, animal studies connect high sodium intake to the gut-immune axis and highlight the gut microbiome as a potential therapeutic target to counteract salt-sensitive conditions and hypertension. The objective of this project is to determine the effects of high salt intake on gut microbiota composition and gut intestine barrier integrity, leading to increased BP in humans. The investigators also hypothesize that high salt intake affects the gut microbiome in a sex-specific manner. In this pilot study, The investigators also test whether telehealth or in-person nutritional coaching help to decrease dietary sodium intake and improve diet quality

The COVID-19 pandemic is the biggest medical challenge in decades. Individuals with pre-existing cardiovascular diseases have a higher risk of severe disease and death from COVID-19. The SARS-CoV-2 virus causes infection by targeting a molecule on the walls of the cells lining the lungs and the blood vessels leading to injury. There are concerns that after recovery from COVID-19, the damage sustained by these cells may have long-term consequences including high blood pressure, stroke and heart attacks. The burden of high blood pressure as a result of the pandemic is unknown and a greater understanding of COVID-19 impact on blood pressure and its underlying mechanisms is urgently needed. LOCHINVAR is based on our pilot study "COVID-19 blood pressure endothelium interaction study" (OBELIX,NCT04409847, IRAS 284453), which found that patients with normal blood pressure at the time of hospital admission with COVID-19 showed a nine-point higher blood pressure ≥12 weeks after recovery, compared to a group without COVID-19. LOCHINVAR will extend the OBELIX study aiming to establish if COVID-19 increases the risk of developing high blood pressure and investigating underlying mechanisms through detailed measurements of blood pressure, blood vessel function, hormones and chemicals in the blood, urine and stool. The investigators will invite 150 adults without pre-existing high blood pressure who were discharged from hospital after an admission: half with COVID-19 and half without. Baseline visit will be ≥12 weeks after discharge for measurements of blood pressure, tests of heart and blood vessel health, blood, urine and stool samples along with questionnaires on mood and quality of life. Two further study visits follow, at 12 and 18 months. This study will generate crucial evidence on the long-term impact of COVID-19 on blood pressure along with information on potential mechanisms of this effect with immediate, transferable impact on clinical practice and inform risk mitigation measures.

To evaluate the post-marketing immunogenicity, safety and antibody persistence of the third dose (booster) of Covid-19 vaccine in patients aged 60 years or older with hypertension and/or diabetes.

Neonatal pulmonary hypertension is a rare but serious condition resulting from a lack of adaptation to extra-uterine life in some newborns. In the short term, the risk of death requires rapid and appropriate management of this transient pathology. In the long term, these newborns present a greater brain vulnerability, a consequence of the pathology itself with cerebral hypoxia but also invasive and aggressive therapies. Although current scientific evidence indicates a correlation with the existence of neurological developmental disorders, the understanding of the long-term neurological outcome of these babies remains poorly documented. Better knowledge of remote neuro-psychomotor development of the critical period

The purpose of this study is to evaluate changes in patient knowledge of blood pressure management and perceptions of making lifestyle changes to manage their blood pressure after implementation of an evidence-based one-page teaching protocol with supplemental handouts and optional use of suggested apps and web sites.

Aim 1: The purpose of the study is to implement the Seventh Joint National Committee on the Diagnosis, Prevention and Treatment of Hypertension (JNC VII) recommendation for monthly visits for hypertensive patients with uncontrolled blood pressure (BP) using a theoretically-informed, empirically grounded, multimodal quality improvement (QI) intervention. Aim 2: To improve BP control and reduce disparity in BP through implementation of monthly visits. Aim 3: To assess potential mediators and moderators of the intervention.

The investigators aimed to investigate the efficacy of calcium channel blockers and beta blockers for controlling tourniquet induced blood pressure increase in patients undergoing carpal tunnel operations with IVRA. For this purpose files of patients undergoing operation under IVRA were retrospectively examined in terms of demographical and hemodynamic variables.

Abstract This is a multi-center, open-label pharmacokinetic (PK) study examining the relationship between the steady-state plasma concentration and dose of treprostinil delivered intravenously or subcutaneously in children with pulmonary arterial hypertension (PAH). Subjects will be divided into 5 cohorts by age. A blood sample will be obtained from each subject at steady state. Additional blood samples will be obtained from a small subset of subjects with a 15% increase or with at least a 15ng/kg/min increase in dose from steady state. Samples will be sent to a pharmacokinetic laboratory for analysis. Linear regression analysis will be used to determine the relationship between the steady state plasma concentration and drug dose. A power model will be used to assess dose proportionality.

The relationship among hypertension, aging and cognitive decline is complex and not completely understood. Purpose of this project will be evaluating early markers of cognitive deterioration in patients with arterial hypertension. In particular, this cross-sectional observational study will be articulated in three phases: Neuropsychological evaluation of general cognitive abilities Identification and measurement of specific biomarker levels Correlation among hypertension, cognitive abilities and biomarkers.
