Active clinical trials for "Essential Hypertension"

The purpose of this study is: To evaluate the effects of NEBILET®(Nebivolol), used as monotherapy or in combination with other antihypertensive agents, in the control of BP and in the metabolic profile of patients with essential hypertension (with or without co-morbidities) after 12 weeks and 24 weeks.

To determine if there is a relationship between coronary flow reserve (CFR) and platelet/plasma BH2 and BH4 levels in patients with high cardiovascular risk .

This study will explore the brainstem activity in response to stress in hypertensive patients and normotensive subjects. In addition, it will evaluate if the response in hypertensive patients can be modulated by blocking the afferent signalling of sympathetic nervous system from the kidney to the brain achieved by renal denervation. The investigators hypothesize that the change in BOLD signal intensity in response to stress is higher in hypertensive patients than in normotensive subjects and that in patients responsive to renal denervation the change in BOLD signal intensity in response to stress is decreased compared to non-responders or to non-denervated resistant hypertensive patients.

The research is planned to evaluate the treatment compliance after the BATHE interview technique in hypertension patients.

Background: Burden: Hypertensive disorders of pregnancy, including preeclampsia, complicate up to 10% of pregnancies worldwide, constituting one of the greatest causes of fetal growth restriction, preterm birth, low birth weight, perinatal mortality, and maternal morbidity and mortality. In Bangladesh, 24% of all maternal deaths are directly attributed to hypertensive causes. Conventional antenatal care practice often delays in or misses diagnosing hypertension in pregnancy, which makes the women vulnerable to its adverse consequences. Knowledge gap: Although there are randomised controlled trials (RCT) of efforts directed at preventing development of hypertension in pregnancy or reducing its complications, there have been no published RCTs of the intervention focusing on regular monitoring of weight gain and blood pressure among pregnant women who are at risk of developing hypertension in pregnancy or its complications to ensure early diagnosis, and thereby optimizing the perinatal outcomes through prompt referral and management. Relevance: To undertake an RCT of intervention to optimize adverse consequences in hypertension in pregnancy raises important practical concerns including: commitment of the enrolled women, the need to make a decision regarding participation due to longer duration of intervention and adherence to protocol. Investigators aim to perform this study to address whether an RCT of the intervention in individual patients is an appropriate trial design, and is feasible. Objectives: To evaluate the accuracy of Salu Health Gauge device in measuring blood pressure. To test the design, feasibility, acceptability and fidelity of a future definitive randomized controlled trial focusing on regular monitoring of weight gain and continuous self-monitoring of blood pressure among pregnant women who are at risk of developing hypertension in pregnancy. Methods: The study will be completed in two steps: 1) the validation of Salu Health Gauge and 2) the pilot trial. The study will be conducted in Matlab, Bangladesh. Salu Health Gauge device will be validated according to the European Society of Hypertension International Protocol revision 2010 (ESH-IP revision 2010) in general adult population (including men and non-pregnant women) as well as in specific groups such as adolescents and pregnant women. The pilot trial is designed as a prospective, two-arm, parallel, and open-label randomized controlled external pilot trial. Eligible participants (pregnant women at risk of developing hypertension in pregnancy) will be individually randomized 1:1 to the intervention arm who will use a wearable device (Salu Health Gauge) from 20 weeks of gestation up to termination of pregnancy alongside conventional antenatal and postnatal care or the control arm who will receive conventional antenatal and postnatal care only. In Matlab, a woman is diagnosed as pregnant by HDSS field staff by 12-16 weeks of gestation and is enlisted. The investigators will obtain this list from HDSS and conduct baseline interviews to identify pregnant women at risk of developing hypertension in pregnancy. Outcome measures/variables: Feasibility outcomes: Recruitment rate, Retention rate, compliance, Acceptability etc. Clinical outcomes: gestational weight gain, birth weight, adverse consequence of hypertension in pregnancy (episodes or occurrence and when), blood pressure profile of high-risk pregnancies, prevalence of specific risk factors for hypertension in pregnancy Serious adverse events

The purpose of this study is to demonstrate the safety and efficacy of inhaled Iloprost (Ventavis®) among adult Chinese patients with primary pulmonary hypertension, which is in compliance with Chinese SFDA regulation.

The aim of the study is to test the following hypotheses: that the function and/or regulation of AQP2 and/or ENaC in the principal cells is abnormal in essential hypertension. if an abnormal function of the principal cells is present in essential hypertension, this will become more pronounced at high and low sodium intake.

The CandLE study with at maximum daily dose of 32 mg candesartan or 16/12.5 mg candesartan/hydrochlorothiazide has the objective to evaluate under naturalistic conditions, i.e. under routine medical care conditions, the impact of the antihypertensive therapy with candesartan or candesartan/HCT on relevant medical parameters related to the left ventricular hypertrophy (LVH) as well as the efficacy and tolerability of candesartan or candesartan/HCT in subjects suffering from essential hypertension..

The number of persons with hypertension is increasing and with it the number of related cardiovascular events and related functional or cognitive declines. While studies have suggested that physical activity, in particular, high-intensity interval training (HIIT), could be as efficient as the commonly used antihypertensive medications, no studies have actually compared their effects in the same population. This protocol will determine if HIIT is at least as efficient as hydrochlorothiazide in order to lower 24h-ambulatory blood pressure (BP) in prehypertensive older adults.

This post-marketing surveillance study was designed to supplement under conditions of normal clinical practice the data on the safety, tolerability and efficacy of Micardis® collected during the clinical studies.
