NCT03708146
This is a single centre, double-blind, randomised, placebo-controlled, parallel staggered group study of BIA 5-1058 in 11 different cohorts of 15 healthy subjects. Subjects will be randomly assigned to receive once-daily oral doses of BIA 5-1058 or matching placebo for 10 days. The primary objectives of the study are to assess the safety and tolerability of BIA 5-1058 after repeated ascending doses under fed and fasted conditions and to assess the pharmacokinetics (PK) of BIA 5-1058 after repeated ascending doses under fed conditions having matching fasting cohorts for comparison of bioavailability. It is planned that comparison cohorts will be dosed in parallel, i.e. Cohorts 1 and 2, 3 and 4, 5 and 6, 7 and 8 and 9 and 10. Cohorts may be split or dosed sequentially for logistical purposes; however, data from both comparison cohorts (e.g. Cohorts 1 and 2) must be available before dose escalation to the next dose levels.
NCT04686643
A phase 3 study to evaluate efficacy and safety of AGSAVI
NCT02214290
Caffeine is an exceedingly popular and consumed pharmacological agent. Although caffeine is primarily consumed from coffee and tea beverages, it is also available in other forms such as sodas, energy drinks, tablets and capsules. Nevertheless, caffeine acutely increases brachial and aortic systolic blood pressure (BP) and arterial stiffness. Arterial stiffness is an independent predictor of cardiovascular disease (CVD) and assessed through pulse wave velocity (PWV). Interestingly, previous studies have proposed that caffeine may increase aortic BP through increases in aortic PWV and augmentation index (AIx), a measurement of wave reflection. Yet, these effects were seen in middle-aged adults with treated hypertension and a wide age range. Therefore, it is imperative to consider that caffeine may cause different effects in young normotensive individuals than in older adults independently of BP levels. Importantly, oral supplementation of the amino-acid, L-citrulline has been shown to enhance the bioavailability of L-arginine levels and nitric oxide (NO) production and, therefore, improve arterial function. L-citrulline supplementation for 7 days given at 6 g/day has shown to increase NO levels while improving PWV. Previous studies by our group also demonstrated that L-citrulline supplementation reduces the BP response to cold exposure; a condition with an increased vasoconstriction. Therefore, the acute effects of caffeine on central and peripheral PWV and BP in healthy young men are yet to be fully evaluated. We hypothesized that acute caffeine intake would increase peripheral and aortic BP and PWV and that L-citrulline supplementation would attenuate the effects induced by acute caffeine ingestion.
NCT00749775

NCT01447485
This study will assess the pharmacokinetics and safety following single dose of valsartan in Japanese pediatric patients with hypertension, chronic kidney disease, or nephrotic syndrome.
NCT02458443
Recent meta-analyses suggest isometric resistance training (IRT) may be superior to aerobic exercise for lowering blood pressure. The investigators intend to conduct the largest, longest, prospective, double-blind randomized controlled trial using isometric resistance training to reduce blood pressure to reduce hypertension.
NCT04671602
COVID-19 has highlighted important deficiencies in our health service where front line staff and pregnant women are being exposed to SARS-Cov-2 through assessments that could be conducted using Connected Health solutions, reducing risks of contracting or disseminating SARS-Cov-2. Currently, pregnant women are not attending GPs or hospitals for BP monitoring for fear of contracting SARS-Cov-2. Uncontrolled or unmonitored hypertension in pregnancy is associated with maternal and fetal morbidity and mortality. The aim of the study is to use home BP monitoring as an adjunct to standard care for women with borderline/suspected hypertension in pregnancy. To reduce the exposure risk for staff and pregnant women, we propose the immediate implementation of ambulatory automated self BP monitoring using the LEANBH platform- an existing integrated platform to monitor pregnant women.
NCT01373086
This study will assess the efficacy and safety of LFF269 compared to placebo after treatment in subjects with essential hypertension.
NCT04649463
Background: Office blood pressure (OBP) is used for diagnosing and treating hypertension but ambulatory blood pressure measurement (ABPM) associates more accurately with patient outcome. The optimal blood pressure in patients with coronary artery disease (CAD) is still unknown. Our objective was to investigate whether physician awareness of ABP after percutaneous coronary intervention (PCI) improved BP-control. Methods: A total of 201 patients performed ABPM before and after their PCI follow-up visit. Patients were randomized to open (O) or concealed (C) ABPM results for the physician at the follow-up visit. The change in ABP and antihypertensive medication in relation to baseline ABP was compared between the two groups.
NCT02796560
The purpose of this study is to compare the efficacy and tolerance of generic travoprost with its brand name formulation. In this open label, randomized, crossover study, the primary outcome will be intraocular pressure and the secondary outcome will be tolerance to the drops, as measured by a subjective questionnaire. Patients will be randomized to receive either brand name or generic travoprost during the first visit. At the second visit 3 weeks later, their intraocular pressure will be measured and a questionnaire will be completed on the tolerance of the medication. Patients will then receive the other formulation of travoprost. At the third and final visit, another 3 weeks later, their intraocular pressure will be measured and a questionnaire will be completed on the tolerance of the second medication.
NCT04641689
This project will examine the effectiveness of an intervention to reduce sedentary behavior in Kansas State University employees who are primarily working from home. We will recruit 100 employees to participate. Participants will be randomly assigned to one of four conditions: desk only, program only, desk + program, or waitlist control. The program will consist of strategies to reduce sitting and increase physical activity in the home environment. We will assess whether the intervention successfully elicits reductions in sitting among employees, as well as changes in cardiometabolic and work-related outcomes.
NCT04015726
The prevalence of cardiometabolic risk is high among South Asians which manifests itself at an early age. Studies have reported that unhealthy food choices, inadequate physical activity and lack of awareness on healthy lifestyle practices pose a huge threat to the increasing prevalence of metabolic abnormalities even at adolescence. In an earlier study conducted in 2006, reported that 68% of the children during their early adolescence had one or more of the cardiometabolic abnormalities such as obesity, central adiposity, increased blood pressure and presence of dysglycaemia and dyslipidaemia. The risk escalated with increasing weight. Therefore, it is imperative to sensitize the children on improving their lifestyle by conducting screening tests and health education programmes in schools by involving teachers. The Investigator have also shown in a study that teachers can be instrumental in imparting knowledge on the prevention of non-communicable diseases such as diabetes by promoting healthy behavioral changes. The proposed study will focus on a) changes in the prevalence of cardiometabolic risk factors over a 10 year period b) health education programme to school children c) recommendations to school teachers (tool-kit) to inculcate improved lifestyle practices to their students.
NCT01264627
A recent National Health Interview Survey reported that breathing exercises were the second most common complementary and alternative medicine practice in the United States, following only the use of "natural products." With such widespread interest in breathing exercises, alone or as a component of practices such as meditation, a need exists for research that examines not only its efficacy, but also investigates potential mechanisms of action. Indeed, a recent National Center for Complementary and Alternative Medicine (NCCAM) Meditation Workshop recommended research to clarify biological pathways by which meditation practices, including breathing exercises, can impact health. To explore mechanisms underlying the health effects of breathing exercises, new translational tools are needed that can measure breathing patterns in both the clinic and natural environment. The primary objective of the present proposal is the application of a new technology to the investigation of pathways by which breathing exercises can affect health. For this project, the health-related outcome measure to be studied is a major cardiovascular risk factor, blood pressure.
NCT03409237
Osmotherapy consists in the therapeutic use of osmotically active substances with the aim of reducing the volume and therefore the intracranial pressure. It therefore represents an essential component in the clinical management of cerebral edema and intracranial hypertension, whether they are a consequence of head trauma, ischemic or hemorrhagic stroke, and neoplasm or neurosurgical procedures. The current study aims at evaluating in vivo the effects on haemostasis parameters of hypertonic saline solutions at different concentration, as compared to mannitol, in patients with neuroradiological signs (CT / MRI) of cerebral edema / non-traumatic intracranial hypertension.
NCT03030807
The investigation serves the identification of pulmonary hypertension (PH) among patients with hypersensitivity pneumonitis (HP). The exact prevalence of PH in HP is unknown. Data from South America indicate that the prevalence of pre-capillary PH amongst patients with HP is higher than 20%. There are no reliable data from Europe so far. According to the investigators previous analysis, more than 400 HP patients have participated in pulmonary rehabilitation at least once in the past 10 years at Klinikum Bad Gleichenberg (Rehabilitation Center for Agricultural Workers in Austria). This collective of patients is to be invited to participate in the study. A diagnostic algorithm will be applied in the clinical trial, in the case of clinical suspicion the diagnosis of PH will be confirmed by right heart catheterization. Besides the determination of the prevalence of PH in patients with HP the investigators aim to assess the reliability of non-invasive methods (e.g. Echocardiography, ECG...) to predict PH.
NCT03546270
Aging is associated with progressive decreases in arterial health and function as well as overall fitness. It is crucial to prevent or reduce the negative effects of aging on the vasculature and fitness components by implementing appropriate lifestyle interventions, such as exercise training. We examined the effects of a swimming (SWM) regimen on arterial stiffness (pulse wave velocity, PWV), blood pressure (BP), wave reflection (AIx), muscle strength and aerobic capacity in elderly women with stage 2 hypertension.
NCT02596165
The significance of parameters of the central hemodynamic is based upon their strong association with left ventricular hypertrophy and target organ damage at the heart. Noninvasive, auscultatory/ oscillometric and therefore easy applicable measurements of the central hemodynamic such as presented by the Schiller BR-102 plus PWA device implicate highly promising potential for research and daily clinical praxis for improved cardiovascular risk assessment on the population level. The purpose of this study is to evaluate the validity of the central and peripheral blood pressure and central arterial stiffness measured with the device BR-102 plus PWA from Schiller (Schiller AG, Baar, Switzerland).
NCT03544307
Aging is associated with hormonal imbalances and progressive decreases in arterial health and function. It is crucial to prevent or reduce the negative effects of aging on hormonal balance and the vasculature by implementing appropriate lifestyle interventions, such as exercise training. We examined the effects of a 12-week Taekwondo training program on blood catecholamines, arterial stiffness (pulse wave velocity, PWV), blood pressure (BP), resting heart rate, and muscular strength in postmenopausal women with stage 2 hypertension.
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.
