Active clinical trials for "Hypertension"

Few reports have addressed mental health for women with pregnancy complication over a prolonged time period. Meanwhile, the caring model with intervention for women who have pregnancy complication needs to be developed. The aims of this study are to (1) describe and compare the differences in health indicators during pre-pregnancy, pregnancy and 1 year postpartum; (2) develop the theoretical framework of relationship among health indicators during perinatal period; (3) develop a telephone follow-up and consultation program and examine its effect on women's resilience, depression, anxiety and quality of life. In the first stage, a prospective longitudinal investigation will be performed in women at pregnancy and postpartum. Women with pregnancy-related complications will be recruited. All participants will complete questionnaires that assess demographic characteristics, obstetric and birth history, depression, anxiety, resilience and quality of life. Participants who are in early, middle, late pregnancy, 3-5 days, 1st, 3rd, and 6th month and 1 year postpartum will be contacted to complete the questionnaires by mail or at study site clinics. The sample size was estimated by drop rates and power calculation. Approximately 380 women in early pregnancy will be recruited at a medical center in northern Taiwan. The first stage of this study will be conducted over a 3-year period. In the second stage, randomized control trial with single blind will be used to recruit eligible subjects from women in the waiting room for prenatal examination at a medical center in Taipei. The eligible subjects will be randomized into a control or experimental group. The women in the control group will receive usual care and those in the experimental group will receive four instances of telephone follow-up or face-to-face consultation. Two groups will receive 3 times measurements of depressive symptom, anxiety, resilience and quality of life. Meanwhile, Investigators will assess the health indicators of women's newborn. Data will be analyzed by independent t-test and generalized estimating equations. Forty-eight subjects will be recruited in each group. Totally, 300 subjects will be approached in terms of including a 30% dropout rate. The second stage of this study will be conducted over a 2-year period.

This study aims to investigate the relationship among self-efficacy, anxiety, depressive symptoms, quality of life, lifestyle, heart rate variability and blood pressure control; and to examine the effects of self-titration strategy on self-efficacy, anxiety, depressive symptoms,heart rate variability, sodium excretion, lifestyle modification,quality of life, and blood pressure control in patients with hypertension.

48 patients, over the age of 18, with pulmonary arterial hypertension (PAH) classified as WHO III-IV, that are all stable under Macitentan therapy ( medication for treating PAH patients), will be recruited to the study through the pulmonary hypertension (PH) clinic at Soroka Medical Center. The patients will be randomly divided into an intervention group, which will exercise twice a week for 12 weeks, supervised by physiotherapists, and a control group, which will only receive the medication. Tests will be performed before the beginning of the intervention program, 6 weeks after it has begun, at the end of the 12 week program, and 3 months after finishing the program.

The present prospective study aims to assess the efficacy of using the telehealth solution "Hypertension Monitor" in patients with hypertension by comparison to the standard care.

The purpose of this study is to determine the effects of Apelin on the lung circulation. The investigators hypothesise that Apelin will relax the lung blood vessels and improve the pumping ability of the heart.

In this study we hypothesize that blocking the angiotensin II AT1-receptor improves the insulin-induced microvascular dilatation. Objectives: 1. Does blockade of the angiotensin II AT1-receptor improve the insulin-induced microvascular effects in hypertensive patients. 2. Does blockade of the angiotensin II AT1-receptor impair the insulin-induced microvascular effects in normotensive control subjects?

Patients with obstructive sleep apnea syndrome have permanent variations of their hemodynamic parameters during the night : heart rate, arterial blood pressure, cardiac output. This is due to the repetition of respiratory events (obstructive apnea and hypopnea) leading to frequent micro-arousals. These disorders have several consequences : hypertension, NO-dependent vasodilatation impairment, baroreceptor reflex impairment, insulin resistance and other cardiovascular impairments.

This study aims to assess the impact of training General Practitioners (GPs) on adherence to antihypertensive medication among hypertensive individuals. It also aims to assess risk factors for non-adherence. Special training (in appropriate algorithms for management and patient involvement in therapeutic decision making) has been given to GPs. The study has been conducted in six middle or low income clusters of Karachi recruiting individuals randomized to specially trained or untrained GPs, with a follow-up period of 6 weeks. The medication event monitoring system (MEMS)has been used for assessing adherence. It is hypothesized that compliance levels of individuals going to specially trained GPs is higher compared to those going to GPs not having received special training.

High blood pressure in pregnancy is associated with poor outcomes for both mum and baby, increasing the risk of pregnancy complications including pre-eclampsia, fetal growth restriction and preterm birth. The development of new blood pressure lowering interventions suitable for use in pregnancy is a key research priority. Inorganic nitrate is a compound found in certain types of food, particularly green leafy vegetables and beetroot. Nitrate provides an important source of nitric oxide (NO), a molecule involved in keeping blood vessels healthy and regulating blood pressure. Supplementation with nitrate in the diet, using interventions such as beetroot juice, has been shown to reduce blood pressure and improve blood vessel function. In order for dietary nitrate to have these beneficial effects, it needs to be converted in the body to nitrite, via bacteria that live in the mouth (oral bacteria). Differences in oral bacteria, and how they metabolise nitrate, are thought to influence blood pressure regulation and potentially response to dietary nitrate supplementation. This study aims to understand (1) whether pregnant women with high blood pressure have a different composition of oral bacteria compared to healthy pregnant women and women who are not pregnant, and (2) how differences in oral bacteria affect blood pressure responses to a dose of dietary nitrate (in the form of beetroot juice).

There are data supporting a possible increase in the prevalence of High Blood Pressure (HBP) in pediatric patients with Sleep Disorder Breathing (SDB). Adeno-tonsillectomy has proven to be an effective treatment in the correction of nocturnal respiratory events in the majority of patients. Our objective is to determine the presence of HBP in pediatric patients with SDB and the impact of adenotonsillar surgery on its correction. Methodology: 286 children (4-18 years old) will be included consecutively referred for suspected SDB. Variables: a) Clinical history; b) Anthropometric variables: weight, height, body mass index, neck, hip and waist perimeter c) Chervin questionnaire d) polysomnography (PSG) for the SDB assessment and e) for the HBP evaluation, ambulatory blood pressure measurement (ABPM) and pulse transit time (PTT) will be performed during 24h. In control group (not SDB) and patients with indication for medical treatment, the same tests will be repeated six months after the baseline visit. In patients with surgery indication, ABPM and PTT will be performed just before the surgical treatment and ABPM, PTT and PSG six months after the intervention. In a subgroup of patients, will also assess the presence of subclinical organic damage produced by HBP: blood markers (creatinine / glomerular filtration), urine (albuminuria / proteinuria), electrocardiogram and echocardiography (left ventricle hypertrophy).
