Active clinical trials for "Hypertension"

A novel radiofrequency (RF) wire created by Baylis Medical (Montreal, CAN) is an FDA cleared device commonly used for percutaneous recanalization procedures. This wire has an active tip that delivers focused RF energy and has been applied for many procedures such as percutaneous transseptal left heart access, recanalization of central vein occlusion, recanalization of arterial occlusion, and recanalization of bile duct occlusion. There has been no study investigating the use of the RF wire for TIPS creation in clinical practice with humans. Having promising results of an experimental feasibility investigation in swine, the investigators are seeking to assess the feasibility and safety of the RF wire to cut through tissue in the liver while creating TIPS in the clinical setting.

The purpose of this study is to determine that effects of an intervention called High-resolution, relational, resonance-based, electroencephalic mirroring (HIRREM), on Stage 1 Primary Hypertension (systolic BP 130-139, and/or diastolic BP 80-89).

Medication errors are common, life-threatening, costly but preventable. Information technology and automated systems are highly efficient for preventing medication errors and therefore widely employed in hospital settings. In this study, investigators would perform a cluster randomized controlled trial of a clinical reminding system that uses DNN and Probabilistic models to detect and notify physicians of inappropriate prescriptions, giving them the opportunity to correct these gaps and increase prescriptions completeness. This study aim is to assess whether or not this system would improve prescription notation for a broad array of patient conditions.

The study is a 2 year community based cluster randomized controlled trial to assess the role that a community health worker led intervention, in concert with physician education, can play in controlling the principal cardiovascular risk factors, i.e. hypertension, tobacco use, diabetes mellitus, physical inactivity and an unhealthy diet. Participants will include around 3600 adults, 35-70 years of age, from the urban community in the town of Dalkhola, Uttar Dinajpur district, West Bengal, India. The hypothesis of the study is that a community health worker based approach can result in increased control of Hypertension, Diabetes and Smoking.

This is a Phase I study of vitamin B3-amide (nicotinamide) dietary supplementation in pregnant women with early onset preeclampsia. The investigators will enroll 10 pregnant women at 24-32 weeks' gestation with the diagnosis of preeclampsia. If the woman is anticipated to remain undelivered for 48 hours after diagnosis she will receive vitamin B3-amide, 500 mg/day given in the morning (n=5) or 1000 mg given in the morning (n=5), continuing until delivery or for 14 days, whichever occurs first. Maternal blood will be collected at baseline and twice a day on days 1, 3, and 7 of nicotinamide administration to measure nicotinamide metabolites, The objectives of this Phase I study are to to test safety of nicotinamide.

Patients with autonomic failure are characterized by disabling orthostatic hypotension (low blood pressure on standing), and at least half of them also have high blood pressure while lying down (supine hypertension). Exposure to heat, such as in hot environments, often worsens their orthostatic hypotension. The causes of this are not fully understood. The purpose of this study is to evaluate whether applying local heat over the abdomen of patients with autonomic failure and supine hypertension would decrease their high blood pressure while lying down. This will help us better understand the mechanisms underlying this phenomenon, and may be of use in the treatment of supine hypertension.

Cardiovascular (CV) disease is associated with significant morbidity and mortality. In the current digital age, needed is a better understanding of how information on social media sites may inform our approaches to improving CV health through novel methodologies. Investigators propose to study the conversation on Twitter about several CV diseases and their associated sequelae.

Acute consumption of dietary nitrate (as beetroot juice) has been shown to decrease systemic blood pressure in multiple populations including newly diagnosed, untreated hypertensives. The additional effect in hypertensives on blood pressure lowering medications is uncertain.

High blood pressure (BP) is a serious public health problem responsible for heart attack, stroke and kidney failure. One in four adults in Singapore has hypertension. We propose a pilot study in 2 polyclinics in Singapore, 1 deliver a structured multi-component intervention and another usual care. A total of 100 adults with uncontrolled high blood pressure will be followed for 3 months. The intervention includes 1) algorithm-driven antihypertensive treatment for all patients using fixed-dose combination and lipid lowering for high risk patients, 2) motivational conversation for high risk patients; and 3) telephone based follow-ups of all patients by a team of physician supervised nurse practitioners and nurses. The change in BP will be compared between intervention and control groups. The structured care including the above mentioned components is likely to be more effective than usual care in lowering BP levels of patients with uncontrolled high blood pressure. Such a program is also likely to be more cost effective in terms of money spent for improving quality of patients' life. The findings of the pilot will inform the design of a larger cluster randomized trial in eight polyclinics in Singapore. If the main study is successful, the findings will be informative for policymakers to roll out intervention in all polyclinics and primary care centers across Singapore, and other countries with similar healthcare infrastructure.

The purpose of this study is to compare the effect of 6-weekly, 20 minute sessions of 2 online behavioral sleep interventions (cognitive behavioral therapy or healthy sleep habits) on blood pressure, sleep, depressive symptoms and anxiety in people with insomnia and prehypertension or hypertension.
