NCT ID: NCT03362047 Not yet recruiting - Clinical trials for Pulmonary Arterial Hypertension (PAH)

(RIGHT HEART III Study - Right Ventricular Hemodynamic Evaluation and Response to Treatment)

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: 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: NCT03348878 Not yet recruiting - Clinical trials for Uncontrolled Hypertension

Descriptive Study of Drug Compliance in Uncontrolled Hypertensive Patients

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

Therapeutic compliance is defined as the degree of coincidence between a person's behavior and prescribing advice given by his or her physician. According to the World Health Organization (WHO), "insufficient adherence is the main reason why patients do not get all the benefits they could expect from their medicines. It causes medical and psychosocial complications, diminishes the quality of life of patients, increases the likelihood of drug resistance, and waste of resources. " In the case of certain conditions such as high blood pressure (hypertension), poor adherence increases the risk of stroke, acute coronary syndrome, and heart failure. In patients with uncontrolled hypertension under treatment, the issue of therapeutic non-compliance should always be considered before considering the dose (supplemental drug) of antihypertensive therapy. For each patient participating in the study, medication adherence (for one of the antihypertensive treatments) will be assessed for 2 months using an electronic pill. The antihypertensive treatments considered for the study belong to the following classes: diuretics, beta-blockers, calcium-blockers, ACE (angiotensin-converting enzyme) inhibitors, sartans. Main objective: care objective: to provide physicians and patients with assistance in case of ineffectiveness or therapeutic escape in a chronic disease such as hypertension, by assessing the compliance profile of each patient. Secondary objectives: to carry out a quantitative typology of drug adherence in patients with unbalanced HTA under treatment.

NCT ID: NCT03344159 Not yet recruiting - Clinical trials for Pulmonary Arterial Hypertension

Spironolactone Therapy in Chronic Stable Right HF Trial

Start date: January 1, 2018
Phase: Phase 4
Study type: Interventional

The purpose of this study is to evaluate the safety, tolerability and mechanistic effects of spironolactone, an aldosterone receptor antagonist, on sympathetic nervous system activity and right heart function and remodeling in patients with chronic right heart failure.

NCT ID: NCT03338426 Not yet recruiting - Clinical trials for Essential Hypertension, Dyslipidemia

A Study to Evaluate the Efficacy and Safety of Combination Treatment of Fimasartan/Atorvastatin in Patients With Essential Hypertension and Dyslipidemia

Start date: November 8, 2017
Phase: Phase 3
Study type: Interventional

The objective of this clinical study is to evaluate the efficacy and safety by comparing the fimasartan/atorvastatin treatment group to the fimasartan/placebo treatment group and the placebo/atorvastatin treatment group respectively at Week 8 in patients with essential hypertension and dyslipidemia.

NCT ID: NCT03334149 Not yet recruiting - Hypertension Clinical Trials

Blood Pressure Monitoring in High Risk Pregnancy to Improve the Detection and Monitoring of Hypertension

Start date: November 10, 2017
Phase: N/A
Study type: Interventional

Raised blood pressure is a common problem in pregnancy. Raised blood pressure and pre-eclampsia affect about one in ten women and are a major cause of death and premature birth in the United Kingdom and worldwide. Many women have expressed an interest in monitoring their own blood pressure in between antenatal visits but there has been very little research to guide this. The investigators would like to know if the diagnosis and subsequent care of women with raised blood pressure can be improved if women were able to monitor their own blood pressure safely at home. This work will test whether optimising the diagnosis, monitoring and management of raised BP during pregnancy through self-monitoring of BP is effective, acceptable and cost-effective compared to usual care. The research team have being working with pregnant women, doctors and midwives to develop a simple and accurate method of self-monitoring of blood pressure in pregnancy. This randomised controlled trial will: 1. Compare self-monitoring with usual care in women at higher risk of hypertension in pregnancy and assess if self-monitoring can identify raised blood pressure earlier. 2. Compare self-monitoring with usual care for women with high blood pressure in pregnancy to see if it leads to lower blood pressure. 3. Assess if self-monitoring is cost-effective. Pregnant women who chose to take part in these studies will be randomised to either usual care or asked to monitor their own blood pressure during their pregnancy in addition to their usual antenatal care.

NCT ID: NCT03323840 Not yet recruiting - Hypertension Clinical Trials

Pilot for a Community Pharmacy Service Model: Impact of a Pharmacist Monitored Patient Blood Pressure Readings

Start date: December 15, 2017
Phase: N/A
Study type: Interventional

This study is designed to explore whether routine measurement of blood pressure by community pharmacists can improve patient adherence to blood pressure medications. The study will utilize an incentivized care approach, in which patients receive a $10 gift card for every time they come to the pharmacy for blood pressure management (up to 2 times/month). The investigators hypothesize that the simple process of coming in for a blood pressure measurement (without any other scripted interventions, counseling, or consultation) will be feasible and sufficient to improve adherence to medications. The investigators will also collect preliminary data to help estimate how these hypothetical improvements in adherence might result in improved blood pressure control, fewer office visits, and (ultimately) fewer adverse cardiovascular outcomes (i.e. heart attacks, strokes, etc).

NCT ID: NCT03318146 Not yet recruiting - Glaucoma Clinical Trials

Safety, Tolerability and Preliminary Efficacy of Unilateral Latanoprost-loaded Punctual Plug -EXP-LP

Start date: June 1, 2018
Phase: N/A
Study type: Interventional

Glaucoma is the most frequent cause of irreversible & preventable blindness worldwide, affecting about 2% of the world's population in people over 40. The major risk factor, and only treatable factor in glaucoma, is increased intraocular pressure (IOP). IOP reduction can slow or arrest the progression of vision loss. Current treatment consists of drops administered on a daily basis with unfortunately low patient compliance, increasing the chance of blindness. Eximore's product aims to eliminate the need to apply eye drops on a daily basis and thus solves the significant problem of patient compliance.

NCT ID: NCT03310684 Not yet recruiting - Pediatric Obesity Clinical Trials

Pediatric Primary Hypertension and the Renin-Angiotensin System (PHRAS)

Start date: December 2017
Phase: N/A
Study type: Observational

Pediatric primary hypertension is increasingly common, occurring in 5-10% of normal-weight children and up to 25% of children with obesity. It is a risk factor for adult cardiovascular and renal disease. But even during childhood, hypertension is associated with significant morbidity, including cognitive impairment and organ damage. In the heart and kidneys, this organ damage is characterized by thickened heart muscle (left ventricular hypertrophy) and spillage of protein in the urine (albuminuria). Obese children are also at risk for fatty liver disease. However, the cause of pediatric primary hypertension, the role of obesity, and the mechanisms behind heart and kidney injury are poorly understood. Due to these limitations, there are no first-line medications, and treatment is often inadequate. An altered renin-angiotensin system may cause primary hypertension and related organ damage. Evidence suggests uric acid, FGF23, klotho, and obesity play a role in renin-angiotensin system-mediated injury. An improved comprehension of the pathophysiology of pediatric primary hypertension could enhance clinical care by targeting treatment to the cause of disease and informing novel measurement of organ damage.

NCT ID: NCT03310229 Not yet recruiting - Clinical trials for Pulmonary Hypertension

Pulmonary Hypertension in Haemodialysis Patients :Frequency and Risk Factors

Start date: November 30, 2017
Phase: N/A
Study type: Observational

High mortality rates due to cardiovascular disease in end-stage renal disease patients been described by epidemiological and clinical studies. It accounts for approximately 50 percent of deaths in dialysis patients. Although controversial, this may be due to the presence of excess vascular calcification particularly in the form of extensive coronary artery calcification which can be observed even in very young dialysis patients. It was suggested that abnormalities of the right ventricular function in patients with end-stage renal disease were largely due to pulmonary hypertension which usually develops secondary to pulmonary artery calcifications.
