NCT02124486
Idiopathic intracranial hypertension (IIH) is a condition with an unknown cause or causes. The condition is associated with raised pressure in the brain and can cause disabling daily headaches and loss of sight, which can be permanent. The raised brain pressure squashes the nerves supplying the eye (also known as papilloedema) and this can affect vision. Over 90% of patients with IIH are overweight and weight loss is the most effective treatment. Other treatments for IIH have very little current evidence to support their use. Weight loss is difficult to maintain. This trial aims to compare two methods of weight loss, bariatric surgery and the most effective dietary programme commonly available, Weight Watchers, to see which offers the most effective sustainable treatment for IIH. Bariatric surgery is recommended by the NICE clinical guidelines for patients with a Body Mass Index (BMI) of over 40, or over 35 with a co-morbidity. Women suffering from IIH have a BMI on average around 38 and IIH is not recognised as a co-morbidity for bariatric surgery. This trial will recruit 64 women with IIH from Neurology and Ophthalmology clinics in UK NHS Trusts. They will be randomised and 32 participants will be allocated to the dietetic intervention arm, and be enrolled in their local Weight Watchers group. 32 participants will be allocated to the bariatric surgery arm, and will be referred to their local bariatric surgery pathway to receive bariatric surgery. Both groups of participants will be allocated to a treatment arm which is proven to bring about weight loss. Participants will then be followed up for five years, with the most important measurement being their brain pressure after one year of being in the trial. A further 20 obese women who don't suffer from IIH will be recruited to compare the baseline symptoms and biomarkers of those with IIH; they will take no further part in the study. 5 further healthy individuals will be scanned twice in an MRI test group to validate the MRI scan sequence to be used in the trial.

Subjects treated with Canagliflozin, Dapagliflozin and Empagliflozin obtained improvement on blood pressure values, body weight and cardiovascular mortality but pathophysiological explanations of these effects are not yet known.
NCT04213963
Prevalence of primary aldosteronism (PA) in resistant hypertension is not clear. In addition, emerging evidence supports the role of elevated serum aldosterone in promoting cardiovascular disease, independently from high blood pressure (BP) levels, but current data on this issue are heterogeneous.
NCT03898518
The purpose of this study was to examine the impact of a 12-week jump rope exercise program on body composition, blood pressure, insulin resistance, and academic self-efficacy in prehypertensive adolescent obese girls. Forty-eight prehypertensive adolescent obese girls participated in this study. The girls were randomly divided into the jump rope exercise intervention group (EX, n=24) and control group (CON, n=24). The EX group performed a jump rope training program at 40-70% of their heart rate reserve (HRR) 5 days/week for 12 weeks (sessions 50 minutes in duration). The CON group did not participate in any structure or unstructured exercise protocol. Blood pressure, body fat percentage, waist circumference, blood glucose and insulin, homeostatic model assessment - insulin resistance, and Academic Self-Efficacy were measured before and after the 12-weeks study.
NCT03254251
We used a parallel experimental design. Following an initial screening and familiarization session of study tests and procedures, eligible postmenopausal women were randomly assigned to a stair climbing (SC) group or non-exercising control group. SC training session was progressive program, and was performed 4 days a week for 12 weeks. Measurements were collected at baseline and after 12 weeks during the same time of day (±1 hour) in the morning following an overnight fast and abstinence from caffeinated drinks, alcohol, and between 48 and 72 hours after the last exercise session.
NCT01051960
The purpose of this study is to determine the clinical characteristics and hemodynamic profiles that predict exercise induced pulmonary hypertension in 15 patients with systemic sclerosis. The study also aims to determine the effectiveness of Ambrisentan for subjects with exercise induced Pulmonary Arterial Hypertension (PAH) with scleroderma
NCT03919201
The purpose of this study was to examine the impacts of a 12-week resistance band exercise program on body composition, aging-related hormones, and blood pressure in postmenopausal women with stage 1 hypertension. Twenty postmenopausal women with hypertension participated in this study. Participants were randomly allocated into the resistance band training group (EX, n = 10) or the control group (CON, n = 10). The EX group performed a resistance band exercise training program at jump rope training program at 40-70% of their heart rate reserve (HRR) 5 days/week for 12 weeks (sessions 60 minutes in duration). The CON group did not participate in any exercise, dietary, or behavioral intervention. Body composition, aging-related hormones (growth hormone, insulin-like growth factor 1, dehydroepiandrosterone, and estradiol), and blood pressure were measured before and after the 12-weeks study.
NCT03155139
To investigate the prevalence of primary aldosteronism (PA) in Chinese patients with newly diagnosed hypertension.
NCT01491646
Pulmonary hypertension (PH) is a condition in which high blood pressure develops in the lungs and right side of the heart. People with PH suffer from shortness of breath, chest pain, heart failure, heart rhythm problems, and fainting. PH is diagnosed using a test called a cardiac catheterization where blood pressure is measured directly using a tube placed in the right side of the heart and lung arteries. Because a cardiac catheterization is invasive, researchers are investigating ways to diagnose PH using imaging tests that are not invasive. The study will evaluate whether or not a magnetic resonance image (MRI) of the heart, and blood tests can detect PH.
NCT02827695
Investigators will employ a 2-arm Randomized Controlled Trial (RCT) design with the subject as the unit of randomization and analysis. Kidney transplant recipients having uncontrolled hypertension will be enrolled into a screening phase to measure medication non-adherence. Each subject will use an electronic pill tray for 1 month without any reminder functions activated. Non-adherent subjects who remain uncontrolled will be randomly assigned to SMASK or Standard Care (SC). SC will continue to use the pill tray with reminders turned off and will receive attention control texts with healthy lifestyle information. SMASK will have the reminder functions of the electronic pill tray activated and will receive a Bluetooth blood pressure monitor and an app to collect the data and send to researchers. Subjects in the second phase will participate in 4 more evaluations at months 1, 3, 6, 12 post randomization. Research staff will measure resting blood pressure and heart rate.
NCT04596358
The study aims at testing the level of adherence to the Mediterranean diet among health-workers, comparing this aspect to the extra-working physical activity, anthropometric measures and prevalence of cardiovascular, metabolic and neoplastic diseases previously diagnosed.
NCT02718638
Oxidative stress and inflammation are cardiovascular risk factors in patients with chronic kidney disease (CKD) undergoing hemodialysis (HD). Nuclear transcription factors play roles in the coordinated expression of genes involved in inflammation, such as nuclear factor Kappa B (NFkB) that increase the cytokines synthesis and Nuclear factor erythroid 2-related factor 2 (Nrf2) that increase the transcription of genes encoding enzymes of phase II detoxifying and antioxidant enzymes. The aim of this study was to evaluate the effects of resistance exercise program on the expression of transcription factors Nrf2 and NF-kB in HD patients.
NCT04339296
Managing and taking medications as prescribed can be a difficult task. This is especially true for older adults living at home with chronic conditions while managing multiple prescribed medications. In response, Catalyst Healthcare has adopted an integrated medication dispensing system that intends to improve patient adherence to medications and quality of care through real-time pharmacists and caregiver support.Catalyst Healthcare has launched an integrated at-home medication dispenser system called spencer. Spencer is a natural extension that plugs into Catalyst's AdhereNet platform, connecting high-risk patients in home care setting to a multi-disciplinary care team in real-time. Study is funded by the Centre of Aging and Brain Health Innovation (CABHI). Investigators are conducting a randomized controlled trial with a target sample size of 100 participants to examine the efficacy of an in-home electronic medication dispensing system (MDS) on improving medication adherence in community-dwelling older adults with chronic conditions. 50 of these participants will be assigned to the intervention group (medication management with Spencer) and 50 will be assigned to the control group (medication management without Spencer). Medication adherence and patient-related data will be collected over a six-month period. Participants health status and characteristics will be obtained through baseline assessment upon enrollment. A monthly follow-up survey will be completed to collect medication management and adherence data. Adherence data for spencer-users will be collected from Catalyst Healthcare technology platform. In the control group, adherence will be measured through monthly medication logs completed by participants.
NCT02492035
The Canadian hypertension education program recommends increased physical activity, adoption of the Dietary Approaches to Stop Hypertension (DASH) diet, and reduction in sodium and alcohol intake for treatment and prevention of hypertension. Objective: To describe patients participating in an interdisciplinary lifestyle intervention to reduce blood pressure in a family medicine primary care setting. Design: Descriptive study. Participants: The study aims to recruit 60 sedentary hypertensive patients to participate in a 6-month randomized-controlled trial. To be eligible, patients must be ≥18 years of age, sedentary (7-day measured steps/day and self-report), hypertensive (based on 24-h ambulatory blood pressure measurements \[ABPM\]), non-smoker, non-diabetic and without dyslipidemia. Intervention: Patients are recruited by health care professionals of the family medicine unit and are thereafter randomized to one of four intervention groups: 1) standard medical care (control), 2) improved diet (DASH diet), 3) physical activity, or 4) both improved diet and physical activity. Patients are evaluated (pre, mid and post intervention), monitored, and educated by the interdisciplinary health care team that includes a physician, a kinesiologist, a nutritionist and a nurse, depending on the intervention group. T-tests and descriptive statistics were used to analyse data. This study will document the efficacy of a primary care lifestyle intervention program on cardiometabolic and hypertension risk factors.
NCT02710071
Patients who have obstructive sleep apnea (OSA) frequently stop breathing while they sleep. They often develop high blood pressure. We are not sure what drug is best to treat the high blood pressure. This study will give the patients nebivolol or hydrochlorothiazide (HCTZ) for 6 weeks after 2 weeks of placebo. The blood pressure response will be evaluated by 24 hour monitoring.
NCT04151537
Personal Activity Intelligence (PAI) is a novel metric developed to quantify the amount of routine physical activity (PA) needed to improve health and reduce cardiovascular (CV) mortality. The PAI metric can be integrated in PA monitors to promote and track PA. The present pilot study is a 12-week randomized controlled trial designed to test the efficacy of PAI in the treatment of high blood pressure. The primary aim is to investigate how routine PA (expressed as PAI level) affect ambulatory blood pressure by comparing the effect of the intervention (≥100 PAI per week) with a control recommended to follow national PA guidelines. The secondary aims are to investigate the effect on a comprehensive CV risk profile, and to model the effect of PAI level on multiple CV parameters. The CV risk profile includes office BP, arterial stiffness, stroke volume, heart rate, cardiac output, systemic vascular resistance, cardiorespiratory fitness, body composition, blood lipid profile and serum markers of glucose metabolism, kidney failure and systemic inflammation.
NCT01774617
It is a cohort to evaluate the power of different diagnostic tests in predicting the prognosis of patients with severe liver disease. Patients with decompensated liver cirrhosis on the waiting list for liver transplantation will be evaluated with comparison of different diagnostic tests according to the MELD score (Model for End-Stage Liver Disease), MELD-Na (Model for End-Stage Liver Disease and sodium), indocyanine green clearance test, hepatic venous pressure gradient and transient elastography. All patients will be submitted to all the tests and prospectively followed for 6 months, to establish mortality and complications related to liver disease in order to define the value of each method to predict outcomes.
NCT02462967
Study GT 026 is a Phase 2, multicenter, parallel group, North American, randomized, placebo controlled, double blind study. This study will enroll subjects with portal hypertension (HVPG greater than or equal to 6 mm Hg) who also have a liver biopsy with cirrhosis (Ishak stage 5 or 6), presumably due to NASH, excluding subjects with medium and large varices and those with decompensated cirrhosis. Subjects with portal hypertension and cirrhosis will be randomly assigned (1:1:1 ratio) to receive 1 of 3 treatment assignments including placebo, GR MD 02 in a dose of 2 mg/kg lean body mass, or GR MD 02 in a dose of 8 mg/kg lean body mass administered every other week over a 52 week period for a total of 26 intravenous infusions. The primary endpoint analysis is the baseline adjusted change in HVPG at 1 year (53 55 weeks) in subjects treated with placebo as compared to subjects treated with GR MD 02 (2 mg/kg/week or 8 mg/kg/week). An esophagogastroduodenoscopy (EGD) with evaluation for varices, HVPG, and liver biopsy will be performed before the first infusion and after the final 26th dose of the investigational medicinal product (IMP). Additionally, subjects will undergo a FibroScan (if available) prior to the first infusion, at Infusion Visit 13, and 14 to 28 days following final 26th infusion, an methacetin breath test (MBT), will be performed if available at screening, at Infusion Visit 13, and 14 to 28 days after the final infusion, and blood will be collected for assessment of biomarkers. All subjects are to attend 2 postdose visits: the first will occur 14 to 28 days after the final dose administration and a second will occur 14 days following the first postdose visit. Subjects will be offered enrollment into a subsequent separate study, an open label extension study, if there is adequate tolerability and no safety issues or signs of clinical progression that would recommend discontinuation. Subjects who do not enroll in the open label extension study will be contacted via telephone every 6 months for 2 years and annually thereafter for a total of 4 years.
NCT03228082
RATIONALE: Women with a previous history of preeclampsia (PE)/HELLP have a twofold higher risk of cardiovascular disease (CVD) and a fourfold increased risk to develop hypertension at a relative young age. In the latest 2016 ESC guidelines 'CVD prevention', previous PE has been acknowledged as a serious CVD risk factor in women. In clinical practice, however, these women are still underappreciated for their CVD risk. It has not been established yet how adequate lifelong prevention in these potentially high risk women can optimally be achieved from their childbearing years onwards. OBJECTIVE: To evaluate feasibility, usability, acceptance and potential obstacles of blood pressure (BP) home monitoring in high-risk women, aged 40-60 years, after a previous PE in pregnancy. In addition to evaluate the effectiveness of BP home monitoring on the occurrence of hypertension, the efficacy of BP treatment, quality of life (QOL), health-related symptoms, work ability and life-style behaviour. STUDY DESIGN: Randomized, open label feasibility study to compare eHealth guided self management of BP monitoring and lifestyle advice with 'usual care'. STUDY POPULATION: Approximately 200 women, aged ≥ 40 and ≤ 60 years, with a previous PE in pregnancy will be invited to participate (both early and late PE). Patients will be recruited from the departments of obstetrics/gynaecology in 6 centres in the Euregio Rhein-Waal and from the department of cardiology Radboudumc. INTERVENTION: eHealth guided measurements of BP at regular intervals and recurrent lifestyle advice (intervention-group) will be compared with "usual care". PRIMARY OUTCOME: Feasibility, usability, acceptance and potential obstacles of BP home monitoring in high-risk women after a previous PE in pregnancy at 1 year of follow-up.
