Filter by:The investigators' central hypothesis is that early combination therapy with two PAH-specific oral therapies that have been shown to be well tolerated in the pediatric population, sildenafil and bosentan, will result in better World Health Organization (WHO) functional class at 12 months after initiation of PAH treatment than therapy with sildenafil alone.
Gastrodia and Uncaria Recipe is a well-known effective prescription in Traditional Chinese Medicine (TCM) to treat hypertension of liver yang hyperactivity type, which manifests symptom of headache or dizziness. However, it lacks consolidated evidence by multi-center randomized controlled trials. The hypothesis of this study is that Gastrodia and Uncaria granule may have significant anti-hypertensive effect on patients with stage-one hypertension and liver-yang hyperactivity syndrome than placebo. This study is a randomized, controlled, multi-center, double-blind clinical trial. This study aims to recruit 500 hypertension patients who 1) are untreated or taking anti-hypertensive medicine for at least two weeks and 2) have an office systolic blood pressure of 140-159 mmHg, an office diastolic blood pressure of <100 mmHg, and a 24-hour ambulatory mean systolic blood pressure of >=130 mmHg. The patients will be stratified according to center, sex, and the TCM type of liver yang hyperactivity/ liver yang non-hyperactivity, and are then randomly assigned to the treatment of Gastrodia and Uncaria granules or placebo for 2 months. The blood pressure lowering effect is evaluated by 24-hour ambulatory systolic blood pressure (primary outcome) / diastolic blood pressure, as well as by home and office blood pressures.
Idiopathic intracranial hypertension (IIH) is a condition of unknown etiology, primarily affecting overweight females of childbearing age. Typically, patients experience headache and visual symptoms due to increased intracranial pressure (ICP) and papilledema. The diagnosis is difficult, and outcomes vary from no sequelae to blindness or chronic headaches. No clear prognostic indicators exist. Treatment consists of medication, weight loss, and possibly surgical intervention.There is an unmet need of defining biomarkers with prognostic or diagnostic value and defining predictors of a poor outcome. This project is a prospective, population-based cohort study including clinical data and a biobank (blood samples and cerebrospinal fluid). The investigator's primary aim is to identify biomarkers of diagnostic or prognostic value and to create a clinical IIH database. The clinical database will answer questions about patient characteristics at baseline and during follow-up, identify predictors of outcome, and help create a standardized programme for follow-up and
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.
The aim of study is to assess the angioprotective effects of antihypertensive combination therapy with perindopril 10 mg and moxonidine 0.4-0.6 mg in patients with arterial hypertension, metabolic syndrome, and obesity, who had Pulse Wave Velocity (PWV) > 10 m/s on the previously administered two-component combination antihypertensive therapy. Open-label non-comparative prospective study for 24 week for each patient.
Experimental data have shown that timing of sodium intake impacts diurnal patterns of sodium excretion. The purpose of this study is to test the hypothesis that the time of day for salt intake impacts (1) blood pressure rhythms and urinary sodium excretion and (2) circadian timing of factors responsible for blood pressure regulation and cardiometabolic health in obese individuals. These studies will address two aims. The first aim will test the hypothesis that limiting high salt intake prior to sleep increases day-night differences in blood pressure, improves timing of urinary sodium excretion, and improves metabolic risk factors. The second aim will test the hypothesis that limiting high salt intake prior to sleep preferentially improves rhythmicity in peripheral vs. central circadian clock factors linked to renal sodium handling. The proposed hypothesis-driven studies will determine how timing of sodium intake affects diurnal blood pressure and circadian timing of factors responsible for blood pressure control and metabolic health, with the ultimate goal of identifying novel strategies to treat nocturnal hypertension and metabolic disease in obesity.
This is a multi-center, prospective cohort study that collects only diagnostic and therapeutic data in subjects but does not interfere with treatment.
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.
To define the cytokine and cellular immune signature of primary hypertension. Cross sectional clinical/laboratory study.
The HOKUSAI post VTE study contains of two different research questions; one on the long term outcomes of deep vein thrombosis and one on the long term effects of pulmonary embolism, post thrombotic syndrome (PTS) and chronic thromboembolic pulmonary hypertension (CTEPH) respectively. Our aim of the study is to compare the long term outcomes along with the quality of life assessment of VTE in a group treated with heparin+VKA versus a group treated with heparin+edoxaban in the acute setting.
