NCT ID: NCT03365479 Recruiting - Clinical trials for Pulmonary Hypertension

Acute Response of Iloprost Inhalation Using the Breelib Nebulizer in Pulmonary Arterial Hypertension

Start date: May 1, 2017
Phase: N/A

Start date: February 1, 2018
Phase: Phase 2
Study type: Interventional

Pilot study to determine the therapeutic effect of two prarallel groups treated with either Ricuguat or Macitentan, evaluated by the change in systolic and diastolic RV function within 12 weeks after first drug intake in order to plan a larger Phase II study.

NCT ID: NCT03360669 Recruiting - Hypertension Clinical Trials

Comparison of Blood Pressure Measurement With an Omron HEM-907 Device in a Clinical Setting and a Research Setting

Start date: November 27, 2017
Phase: N/A
Study type: Interventional

Automated office blood pressure (AOBP) devices are recommended for high blood pressure diagnosis. One of those devices is the Omron HEM-907 (Omron Healthcare). It is currently not known if blood pressure measurements performed with this device in a clinical setting are equivalent to those made in a research setting. Therefore, this randomized-controlled trial was designed. It aims to compare the blood pressure measurements performed in a clinical and a research setting. Seventy patients will be included and randomized to a clinical/research or research/clinical sequence.

NCT ID: NCT03354897 Recruiting - Hypertension Clinical Trials

Clinical Study of UMOD MKCC2 Interaction on Salt-sensitivity in Hypertension

Start date: April 5, 2017
Phase: Phase 4
Study type: Interventional

The hypothesis is based on UMOD rs13333226 genotype, there are two strata of hypertensive patients. The High-UMOD group (AA genotype) has increased UMOD excretion, greater salt sensitivity, HTN, normal eGFR and greater BP response to loop diuretics like furosemide. The Low-UMOD group (G allele) has decreased UMOD excretion, salt resistance, increased eGFR, increased proximal tubular reabsorption of Na (possibly related to increased GFR), a poor BP response to loop diuretics, and possibly diminished function of NKCC2. The High-UMOD strata will have decreased delivery of Na+ to the distal tubule and collecting duct because NKCC2 function is normal and the study hypothesis is that the participants will be more responsive to loop diuretics. In contrast, the Low-UMOD group (G allele) will not show a similar response to loop diuretics. This may be related either to lower Na delivery to the TAL, because of increased proximal tubular reabsorption of Na+, or a suppressed function of NKCC2. The population distribution of the High-UMOD group (AA) is 67%. Our overall objective is to test the hypothesis that hypertensive subjects with uncontrolled HTN open possessing the AA genotype of rs13333226 will be better responders to loop diuretics compared to those possessing the G allele.

NCT ID: NCT03354143 Not yet recruiting - Hypertension Clinical Trials

Hypertension, Intracranial Pulsatility and Brain Amyloid-beta Accumulation in Older Adults (HIPAC Trial)

Start date: February 15, 2018
Phase: Phase 2
Study type: Interventional

The aim of this study is to determine if lowering blood pressure using FDA approved medication (antihypertensive drugs) alters brain pulsatility and reduces brain amyloid beta protein accumulation in older adults. Amyloid beta protein is high in the brain of older adults with Alzheimer's disease. Hypertension may increase brain amyloid beta protein accumulation and affect memory and thinking ability in older adults. However, whether lowering blood pressure reduces brain amyloid beta protein and improves brain function is inconclusive. The investigators hypothesize that treating high blood pressure alters brain pulsatility, which in turn reduces brain amyloid beta protein accumulation and improves brain structure and function.

NCT ID: NCT03351504 Enrolling by invitation - Hypertension Clinical Trials

Solar Lighting to Reduce Indoor Air Pollution in Rural Uganda

Start date: December 1, 2017
Phase: N/A
Study type: Interventional

This study evaluates the impact of a solar lighting system on kerosene lamp use, levels of indoor air pollution, and health in women living in rural Uganda. Half of the participants will receive the lighting systems immediately, while the other half will receive them after an 18 month delay.

NCT ID: NCT03349918 Recruiting - Hypertension Clinical Trials

PERsonal ContExtual Precision healTh

Start date: November 6, 2017
Phase: N/A
Study type: Interventional

The exponential growth of physiological, behavioral and environmental data generated through consumer mobile health (mHealth) devices and Internet of Things (IoT) technology provide unprecedented sources of personalized and contextual health information. If linked to clinical health data from the Electronic Health Record (EHR), these data can provide dynamic and individualized views of patient health states and trajectories that can greatly inform clinical care and health-related research. The investigators propose to advance precision health through the development and evaluation of a mobile application and data platform that collects, harmonizes and integrates mHealth and environmental data from patients' daily lives with their clinical histories and electronic health record data. The investigators propose a participatory design approach to implement and evaluate a precision health platform through the study and modeling of hypertension (HTN) and depression in patient communities of UC Davis (UCD) and UC San Francisco (UCSF). These chronic diseases have high prevalence across geography, socioeconomic status, and race/ethnicity, and have significant economic, societal and personal costs. They are considerably challenging to manage due to difficulties in acquiring high-quality and consistent data from patients outside of their clinical care appointments that is so needed for a full view of the patient's disease state. Despite a broad array of self-monitoring devices and consumer applications, mHealth data are not getting into the clinical care process, and patients do not regularly monitor their own health states, particularly during periods of medication change, when frequent assessments are especially important. The investigators propose to conduct a 6-month single arm feasibility study of 200 ambulatory men and women (100 each at UCSF and UCD) with either hypertension or depression to implement an open, web-accessible, standards driven and patient-centric data platform for the integration of patient-reported and clinical data.

NCT ID: NCT03349775 Recruiting - Obesity Clinical Trials

Cardiometabolic Disease and Pulmonary Hypertension

Start date: November 27, 2017
Phase: N/A
Study type: Interventional

This study will investigate if metformin can help people with obesity and high pressures inside their lung blood vessels. Metformin is approved by the U.S. Food and Drug Administration (FDA) to treat diabetes, but metformin is not approved by the FDA to treat pulmonary hypertension. This study will examine whether Metformin will improve the high pressure inside lung blood vessels in people who are obese. The study will help understand the effect of metformin on pressures inside lung blood vessels.
