NCT ID: NCT03578848 Recruiting - Hypertension Clinical Trials

Guiding Hypertension Management Using Different Blood Pressure Monitoring Strategies

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

Patients with uncontrolled or newly diagnosed hypertension will be randomized to have hypertension management decisions made on the basis of the unattended automated blood pressure (uAOBP) , home BP, and central BP monitoring. This study evaluates the optimal guiding strategy for hypertension will help define which BP monitoring is the most effective strategy to guide the clinical management of hypertension.

NCT ID: NCT03578042 Recruiting - Hypertension Clinical Trials

Fixed-Free HTN Trial

Start date: April 1, 2017
Phase: Phase 4
Study type: Interventional

Evaluation of the effect of FIXED triple anti-hypertensive therapy with losartan-amlodipin-HCTZ vs any free triple combination therapy chosen by the treating physician for patients with uncontrolled hypertension

NCT ID: NCT03577990 Not yet recruiting - Clinical trials for Uncontrolled Hypertension

Technology Coaching Intervention for Black Women With Hypertension

Start date: May 2019
Phase: N/A
Study type: Interventional

Hypertension (HTN) is a global problem affecting 972 million adults and an important public health burden since it is the main cause of cardiovascular disease and death, and the second leading cause of disability. Disproportionately affected, Black women have the highest prevalence of hypertension in the United States. This research will evaluate potential interventions for possible community-based strategies for controlling hypertension using interactive self-care strategies with coaching and technology. We hypothesize that participants who receive self-care management and interactive coaching with technology will have lower systolic/diastolic BP and better adherence to antihypertensive medication(s) and lifestyle recommendations post intervention compared to participants receiving self-care management alone.

NCT ID: NCT03576885 Not yet recruiting - Clinical trials for Pulmonary Hypertension

Inhaled Nitric Oxide for Pulmonary Hypertension and Bronchopulmonary Dysplasia

Start date: September 2018
Phase: Phase 1/Phase 2
Study type: Interventional

Inhaled nitric oxide (iNO) is an effective treatment for pulmonary hypertension (PH) in term and near-term infants. Preterm infants are at risk for early PH that is associated with high risk for bronchopulmonary dysplasia or death. In multiple clinical trials, iNO treatment was not effective for BPD prevention. However, infants were not screened for PH and iNO treatment was not targeted for PH. iNO treatment for PH in preterm infants is controversial due to lack of evidence. The study team hypothesizes that early diagnosis of PH (72-96 hours of life) and iNO treatment will decrease the incidence of death and bronchopulmonary dysplasia and improve oxygenation in extremely preterm infants. 1. To determine if iNO treatment of extremely preterm infants with early pulmonary hypertension as established with echocardiographic evidence at 72-96 hours of age will decrease incidence of death or BPD. 2. To determine if iNO treatment of extremely preterm infants with early PH will decrease the pulmonary artery pressure and improve oxygenation within 72 hours of intervention.

NCT ID: NCT03572036 Active, not recruiting - Sickle Cell Disease Clinical Trials

Phosphodiesterase Type-5 Inhibitor Therapy in Sickle Cell People With Pulmonary Hypertension

Start date: June 26, 2018
Study type: Observational

Background: Sickle cell disease (SCD) is a common inherited blood disorder. Many people with SCD are at risk to get pulmonary hypertension (PH). PH means that the blood pressure in the blood vessels to the lungs is high, and is a serious disease and. Very few studies have looked at the success of treatments for PH in people with SCD. Researchers want to learn more about treating PH with a type of drug called phosphodiesterase type 5 inhibitors (PDE5-I). They will look at the records of people who have already joined other studies. Objective: To identify people who already joined NIH SCD protocols whose medical records should be reviewed. The review will look at the description of SCD patients with PH who have already taken PDE5-I and the outcomes for these people. Eligibility: Adults ages 18 and older with SCD and PH. They must have joined certain NIH studies and taken PDE5-I therapy for at least 16 weeks. Design: This study is a review of medical records. Researchers will collect data from databases of existing studies. They will identify people in those studies who have SCD and PH and took the study drug for at least 16 weeks. Researchers will review the full medical records of those people. From that review, researchers will find participants who meet the inclusion criteria. They will extract data from those records. Researchers will analyze the data. This includes results from heart and lung tests, imaging, and walking tests. It will also include results of a procedure called right heart catheterization. Demographic data and lab data will also be collected. Researchers will remove identifying information from the data, then share it in a database.

NCT ID: NCT03567668 Recruiting - Clinical trials for Pulmonary Arterial Hypertension

Surgical Valvuloplasty for Congenital Mitral Insufficiency

Start date: January 1, 2012
Study type: Observational

Congenital mitral insufficiency is one of the most common valvular diseases in the pediatric population worldwide, carrying a high morbidity and mortality risk if not treated immediately and properly. Given that mitral replacement likely increased risk of cardiac dysfunction and mitral reoperation, mitral repair is the currently preferred surgical strategy in the majority of pediatric patients with mitral insufficiency. Unfortunately, previous evidences demonstrated the long-term hemodynamic alteration in response to significant mitral regurgitant might lead to a reversible or irreversible pulmonary vascular remodeling regardless of concomitant other cardiac malformations, which is associated with increased risk of morbidity and mortality following the surgery. Currently available researches mainly focused the association of pulmonary vascular pressures with risk of mortality and morbidity on adult rheumatic or degenerative mitral insufficiency; however, knowledge is still lacking regarding pediatric population with congenital mitral insufficiency. The investigator wil assess the relationship between baseline sPAP and risk of operative morbidity and mortality.

NCT ID: NCT03566654 Not yet recruiting - Clinical trials for Essential Hypertension

Clinical Trial on Remote Ischemic Conditioning and Hypertension(HOPE)

Start date: July 2018
Phase: Phase 2
Study type: Interventional

Nowadays, the incidence of stroke in China has reached 1.6‰, and this disease has became a primary cause of death in China. One of its major risk factors is hypertension. As shown in the researches, the risk of stroke grows remarkably when the blood pressure increases and there exists a log-linear relationship between them. Systolic pressure and diastolic pressure relate to the risk of stroke independently. Systolic pressure decreasing 10mmHg will reduce the stroke risk by 31% and decrease of 1~3mmHg will reduce the stroke risk by 20~30%. As to diastolic pressure, 5mmHg decrease of it will reduce the stroke risk by 34% and 10mmHg decrease of it will reduce the stroke risk by 56%. In addition, patients with isolated systolic hypertension (SPB≥160mmHg, DPB≤90mmHg) or critical isolated systolic hypertension (SPB=140~159mmHg, DPB< 90mmHg) will suffer a higher risk of stroke than people with normal blood pressure. The ACC has already revised its Hypertension Management Guidelines of standard of diagnosis for hypertension and timing of starting medical treatment in hypertensive patients.Because more and more reseaches shown that people with blood pressure between 120-139/80-89mmHg have higher risk of ASCVSD compared to those with blood pressure lower than 120/80mmHg; However, in China, the diagnostic criteria for hypertension has not been revised yet. Therefore, we still have blind spot in treating such patients who suffer from borderline systolic hypertension at 130~140 mmHg of blood pressure with or without ASCVD or those with the first stage hypertension but refusing to take anti-hypertension drugs. What is more, most of them are middle-aged adults, once they have stroke, it would lead terrible and costly consequences to both their family and the society. Thus, it is necessary to explore new non-pharmacological methods to control blood pressure for reducing the risk of stroke.
