Active clinical trials for "Hypertension"

Specific Aim 1: To develop a patient-reported, EHR-integrated system to actively monitor the safety and effectiveness of treatment for patients taking FDA-approved medications for one of four common chronic conditions (diabetes, hypertension, insomnia, depression), with integrated management support by a pharmacist. Specific Aim 2: To measure the reach, effectiveness, adoption and implementation of this integrated module for adult primary care patients in the Brigham and Women's Primary Care Practice-Based Research Network.

Background: Hypertension is a serious public health problem responsible for significant mortality and morbidity from cardiovascular disease. In Singapore, 1 in 4 adults age 30 years or older suffer from hypertension. Nearly half of these patients have uncontrolled hypertension and only 50% of individuals are on antihypertensive treatment. Our study aims to evaluate the effectiveness, cost effectiveness and impact on medication adherence of a well-structured program using multicomponent intervention for hypertension control aimed at overall cardiovascular risk reduction among individuals with hypertension attending the polyclinics in Singapore, compared to existing services. Such a program is expected to be cost-effective in terms of improving hypertensive individuals' outcomes, and to be potentially scalable and sustainable. Methods/design: Cluster randomized trial of 8 of the nine SingHealth Polyclinics randomized to intervention or usual care (4 each) and followed up for 2 years post randomization Intervention: The structured multicomponent primary care program comprises of: 1) algorithm-driven antihypertensive treatment for all hypertensive individuals and using fixed-dose combination (FDC) and lipid-lowering medication for high-risk hypertensive individuals, 2) motivational conversation for high-risk hypertensive individuals, 3) Follow-up of all hypertensive individuals on improving blood pressure (BP) as a primary outcome and other cardiovascular risk factors as a secondary outcome, and 4) discounts on FDC antihypertensive medication Usual care: The participants attending polyclinics randomized to usual care will continue to receive treatment from the health providers according to existing practices. The hypertensive individuals will also continue to pay for the services (physician or nurse consultation) as per their existing model of reimbursement. Participants: A total of 1000 participants will be recruited, 125 from each of the 8 polyclinics. Recruitment will be in batches of 4 and 4 clinics sequentially (balanced by randomization group). Outcomes: All hypertensive individuals will be assessed by trained outcomes assessors independent to treatment at baseline, 1-year and 2-yeat post randomization. The primary outcome will be the change in systolic blood pressure from baseline to 2 years. Primary Cost-Effectiveness measures will be- 1) Incremental cost per mm Hg systolic BP reduction from baseline to end of follow-up at two years post randomization; 2) incremental cost per projected CVD disability adjusted life years (DALYs) averted and quality adjusted life years (QALYs) saved, and 3) incremental cost per change in cardiovascular risk score from baseline to final follow-up at two-year post. The impact of effect on adherence to antihypertensive and lipid medication will be measured using data on adherence obtained from polyclinic pharmacy records and clinic notes. An average of percent adherence to antihypertensive and lipid lowering will be computed as a composite score. The change in percent composite adherence to antihypertensive and lipid medications from baseline to follow up will be compared between the intervention and control groups.

Objective: To investigate the effect of aromatherapy on blood pressure and stress response by inhalation and foot massage in individuals with essential hypertension. Methods: The randomized controlled trial is performed with 69 individuals diagnosed with essential hypertension hospitalized. There are two interventions (group 1: aromatherapy-inhalation method, group 2: aromatherapy-foot massage) and a control group in the study. Blood pressure is measured with a digital sphygmomanometer after 10 minutes of rest; stress response is determined by heart rate, blood cortisol levels and anxiety scale. Aromatherapy with lavender oil is applied to the intervention groups; no application is made to the control group and routine follow-up at the hospital continued.

The purpose of the study is to test if a Pharmacist Intervention Program with home blood pressure monitoring (HBPM) improves or controls pharmacological adherence and blood pressure levels in hypertensive patients under pharmacological treatment, compared to those who receive usual care in a community pharmacy setting.

We are comparing the blood pressure-lowering effects of two marketed medications, Coreg CR and Toprol XL. Although both drugs reduce blood pressure by blocking the action of noradrenaline on beta-receptors in the blood vessels, Coreg CR also blocks alpha-receptors, which may provide added blood pressure-lowering. In addition, Coreg CR may have anti-oxidant actions. Cells which line blood vessels (termed "endothelial cells") make nitric oxide (NO), which relaxes the muscle cells encircling the blood vessels, causing a reduction in blood pressure. When body cells use oxygen, they normally produce "free radicals", which can destroy NO,leading to high blood pressure, heart damage and worsenimg of diabetes. Antioxidants remove free radicals and prevent or repair this damage. In this study we will measure endothelial cell function, blood vessel wall stiffness, NO in exhaled breath, and blood levels of substances which reflect NO production and destruction to determine if a pure beta-blocker (Toprol XL) differs from an alpha/beta blocker (Coreg CR) in these effects. We will also examine the mechanism by which such differences might occur.

Huzhou City, Zhejiang Province was chosen as the research site, and a general hospital was randomly selected. The "Chinese version of hypertension health literacy scale" of the tutor of this research group was used to evaluate the health literacy level of inpatients with hypertension in the Department of Cardiology, and the patients with critical and lack of health literacy were selected as the research objects. In the control group, routine health management was carried out. On the basis of the control group, the intervention group used health education tools combined with health literacy intervention to implement interactive health management for 12 months. The results of the intervention measures were compared to evaluate the effects of the intervention measures on improving the health literacy level, Hypertension Self-care ability, quality of life and reducing systolic and diastolic blood pressure, body mass index, waist circumference, physiological and biochemical indicators of the patients, so as to provide theoretical basis and practical reference for the further development of prevention and treatment strategies of hypertension patients.

Pulmonary hypertension (PH) is a disorder of high blood pressure that impacts the heart and lungs. Approximately, 50% of individuals with PH experience anxiety or panic disorders. There is limited evidence on psychological treatments for anxiety in PH; however, results support the use of Cognitive Behavioural Therapy (CBT). Despite the prevalence and impact of anxiety in PH; there are no widely available and/or disease specific pathways, thus highlighting an unmet need in this population. This project aims to develop and pilot, using randomised control trial methodology, a self-management intervention for individuals with PH based on principles of CBT.

This study evaluates the impact of the use of a technology-enabled home blood pressure monitor amongst hypertensive patients in primary care. Half of the patients will receive the blood pressure monitor for home monitoring, while the other half will receive usual care at the polyclinic. The hypothesis is tele-monitoring along with nurse led tele-support and medical review (i.e. tele-treatment) can enhance primary care management of hypertension by improving patient outcomes and reducing health costs.

This trial evaluates the effect of providing primary care patients with free and convenient access to a set of essential medicines. Half of the participants will receive free and convenient access to these essential medicines, while the other half will have usual access to medicines.

The MAPA is the reference method to estimate the PA during the SAHOS. The MAPA can be recommended over 48 hours: indeed, the PA falls at the beginning of every apnea then increases gradually up to a pressif peak arising at the time of the ventilatoire resumption. These variations arise under the influence of 4 stimulus: the désaturation in O2, the rise of the PaCO2, the increase of the respiratory effort and the microawakening of the end of apnea who are at the origin of a sympathetic stimulation. Consequently a better diagnostic approach of the HTA (confirmation of a resistant HTA, an identification of the masked HTA and the patients " not dipper " by the MAPA), the identification of the SAHOS, and a better coverage) of the associated cardiovascular risk factors are essential and establish a stake in public health. To investigator's knowledge, no datum or study on the association HTA-SAHOS and its consequences was until then realized in the French overseas departments.
