NCT ID: NCT03428061 Enrolling by invitation - Hypertension Clinical Trials

The ZWOlle Transmural Integrated Care for CArdiovaScular Risk Management Study

Start date: September 1, 2017
Phase: N/A
Study type: Observational

Cardiovascular disease (CVD) contributes importantly to mortality and morbidity. Prevention of CVD by lifestyle change and medication is important and needs full attention. In the Netherlands an integrated program for cardiovascular risk management (CVRM), based on the Chronic Care Model (CCM), has been introduced in many regions in recent years, but evidence from studies that this approach is beneficial is very limited. In the ZWOT-CASE study the investigators will assess the effect of integrated care for CVRM in the region of Zwolle on two major cardiovascular risk factors: systolic blood pressure (SBP) and low-density lipoprotein cholesterol (LDL-cholesterol) in patients with or at high risk of CVD. This study is a pragmatic clinical trial comparing integrated care for CVRM with usual care among patients aged 40-80 years with CVD (n= 370) or with a high CVD risk (n= 370) within 26 general practices. After one year follow-up, primary outcomes (SBP and LDL-cholesterol level) are measured. Secondary outcomes include lifestyle habits (smoking, dietary habits, alcohol use, physical activity), risk factor awareness, 10-year risk of cardiovascular morbidity or mortality, health care consumption, patient satisfaction and quality of life.

NCT ID: NCT03404999 Enrolling by invitation - Hypertension Clinical Trials

Clinical-Decision Support to Improve Hypertension Care in Primary Care

Start date: August 21, 2017
Phase: N/A
Study type: Interventional

Approaches are needed to help primary-care pediatricians address high blood pressure. This study will test whether an electronic health-record-based tool to address high blood pressure is feasible and improves the evaluation and management of high blood pressure in clinical practice. If successful, this approach can be used to address other lifestyle-related and complex health problems (e.g., dyslipidemia and diabetes), then disseminated and used nationwide. The investigators have developed a new, electronic health-record (EHR)-based tool that is designed to help pediatricians: 1. IDENTIFY AND DOCUMENT 1. when a child's blood pressure is elevated, and 2. whether it has been elevated before--including number of prior elevations to document the correct diagnosis (for example, elevated blood pressure, vs. hypertension stage 1, vs. hypertension stage 2), THEN 2. ORDER the next action(s) needed per guideline-based recommendations, AND per prior actions taken--including: 1. laboratories and studies per 2017 updated guidelines 2. follow-up interval in primary care 3. referral to nephrology, when indicated, and 4. patient education on diet/lifestyle modification. The investigators are working on improving this system further with addition of orders for: 1. referral for sleep-apnea testing and treatment, when indicated, and 2. blood-pressure medications (for example, initiation, titration, or addition of agents depending on blood-pressure control, comorbid conditions [e.g., diabetes], and risk for pregnancy)

NCT ID: NCT03401476 Enrolling by invitation - Clinical trials for Pulmonary Arterial Hypertension

Effect of Morphine on Dyspnea and 6-Minute Walk Distance in Pulmonary Arterial Hypertension

Start date: May 8, 2017
Phase: Phase 2
Study type: Interventional

Despite advances in treatment and corresponding improvements in survival, patients with pulmonary arterial hypertension (PAH) remain highly symptomatic. In one survey of 315 patients with PAH, sixty-eight percent had moderate or severe dyspnea on exertion and 40% had a profound and clinically significant deficit in quality of life. Palliative care is being increasingly investigated in life-limiting cardiovascular diseases to alleviate symptoms. In PAH, its implementation is frequently delayed until end-of-life. Opioids are a common palliative care intervention, however the efficacy and safety of opioids for symptom relief in PAH has not been evaluated.

NCT ID: NCT03396302 Enrolling by invitation - Obesity Clinical Trials

Lifestyle On-line Intervention in Patients With Obesity and Hypertension

Start date: January 22, 2018
Phase: N/A
Study type: Interventional

This study aims to describe a totally self-applied online program to promote healthy lifestyles (nutritional education and exercise practice) for obese participants with hypertension. Participants will be recruited from users of a hypertension unit of a public hospital and will be randomized into two groups: experimental group and control group (treatment as usual). The experimental program (3 months) will be composed by 8 modules aimed for promoting healthy eating habits and increase physical activity. Assessment will include: body composition (BMI), blood pressure, glucose metabolism variables, and physical activity level (measured with accelerometers). Design: Randomized Controlled Trial.

NCT ID: NCT03305562 Enrolling by invitation - Hypertension Clinical Trials

Pediatric Hypertension Registry (PHREG)

Start date: September 20, 2017
Phase: N/A
Study type: Observational [Patient Registry]

Pediatric hypertension is increasingly common and is a precursor for adult cardiovascular and renal disease. But even during childhood, hypertension is associated with significant morbidity, including cognitive impairment and organ damage. However, the cause of pediatric hypertension, the response to treatment, and the mechanisms behind organ damage are incompletely understood. Due to these limitations, there are no first-line medications, and treatment is often inadequate. An improved comprehension of the course of pediatric hypertension could enhance clinical care. The goal of this proposal is to create a registry of patients with hypertension to better enable research into this important disease. This patient registry will enhance the investigators ability to quickly collect and analyze data for research studies.

NCT ID: NCT03250819 Enrolling by invitation - Clinical trials for Corticosteroid Induced Ocular Hypertension/Glaucoma

Gene Polymorphisms of Corticosteroid-induced Ocular Hypertension

Start date: September 13, 2017
Phase: N/A
Study type: Observational

Glaucoma is one of the most prevalent eye diseases and the second most common cause of blindness worldwide. The most common form is primary open angle glaucoma (POAG). Glaucoma is a slowly progressing neuropathy of the optic nerve that causes loss of visual field and eventually blindness. Elevated intra-ocular pressure (IOP) is the most important risk factor. Corticosteroids, which are often used for the treatment of many diseases in ophthalmology and other specialities, may cause an elevation of the IOP. It is estimated that corticosteroids induce ocular hypertension in approximately 18%-36% of the general population and in patients with POAG this percentage can be as high as 92%. When the treatment is sustained, this can cause a glaucomatous neuropathy of the optic nerve (corticosteroid-induced glaucoma). The precise pathogenic mechanism isn't clear yet. Genetic factors are likely to affect the susceptibility to corticosteroid response. Therefore, an overview of the genetic mechanisms of corticosteroid-induced glaucoma can give more insight in the pathogenesis. In this study the researchers investigate the occurrence of SNPs (single nucleotide polymorphisms) in 150 cases with a steroid-response in comparison with 300 controls exposed to corticosteroids without a steroid-response. Up to now, one small GWAS has been conducted comparing 32 patients with and without corticosteroid-induced ocular hypertension after treatment with intravitreal triamcinolone. In this study, two SNPs proximal of the transcriptional start site (near the 5') of HCG22 on chromosome 6 were identified. However, this is a rather small sample population and the investigators didn't match for the underlying disease. Further, in another small study, Hogewind et al. performed SNP analysis in multiple genes (SFRS3, FKBP4, FKBP5, and NR3C1) in corticosteroid-induced ocular hypertension. This study enables the investigators to identify patients at risk for developing corticosteroid-induced glaucoma and to gain a better insight in the pathogenesis. This may also lead to the discovery of biomarkers that indicate an increased risk of developing a steroid-induced glaucoma and new prevention and treatment strategies, which are necessary as the treatment of corticosteroid induced-glaucoma now only focuses at lowering the IOP and can still be challenging.

NCT ID: NCT03225183 Enrolling by invitation - Hypertension Clinical Trials

RNA Sequencing in the Framingham Heart Study Third Generation Cohort Exam 2

Start date: February 23, 2018
Phase: N/A
Study type: Observational

Background: The Framingham Heart Study (FHS) was initiated by the U.S Public Health Service in 1948 and turned over to the newly established National Heart Institute in 1951. The FHS is now jointly led by the National Heart, Lung, and Blood Institute and Boston University. The FHS currently studies risk factors, and the genetics of heart and blood vessel disease, and other health conditions in three generations of study participants. Scientists want to use the data collected from this study to do more research. They want to use a technique that determines the sequence of ribonucleic acid (RNA) molecules. Objective: To study genes related to certain diseases and health conditions. These include heart and blood vessel diseases, lung and blood diseases, stroke, memory loss, and cancer. Eligibility: People in the FHS Third Generation cohort who already attended exam 2. Design: Researchers will study samples that have already been collected in the FHS. There will be no active examination or burden to participants. During FHS visits, participants gave blood samples. They gave permission for the blood to be used for genetic research. RNA will be generated from the samples. They will be given a new ID separate from any personal data. They will be stored in a secure FHS lab. The samples will be analyzed. Only certified researchers can access them. No study participants will be contacted in relation to this project.
