NCT ID: NCT03135860 Terminated - Clinical trials for Chronic Obstructive Pulmonary Disease

Effect iNO on Functional Respiratory Imaging in Subjects With WHO Group 3 Pulmonary Hypertension With COPD on Oxygen

Start date: October 2016
Phase: Early Phase 1
Study type: Interventional

The objective of this exploratory study is to examine the utility of high resolution computed tomography (HRCT) to measure changes in functional pulmonary imaging parameters as a function of long term iNO administrationusing the device INOpulse for 4 weeks in relation to Patient Reported Outcome (PRO) and exercise tolerance in subjects with WHO Group 3 PH associated with COPD on LTOT. Changes from baseline to 4 weeks of pulsed iNO and after 2 weeks of withdrawal from pulsed iNO will be evaluated.

NCT ID: NCT03121092 Terminated - Hypertension Clinical Trials

ACEI/ARB Study in Ambulatory and Day of Surgery Admission Patients

ACE/ARB
Start date: May 16, 2012
Phase: N/A
Study type: Interventional

Angiotensin converting enzyme inhibitors (ACEI's) and Angiotensin receptor blockers (ARB's) are commonly used anti-hypertensive medications that may have implications on the management of a patient undergoing surgery. Limited research has looked at the effects of these medications on perioperative complications and mortality. Some studies conducted on small groups of inpatients with advanced vascular disease undergoing vascular surgery or coronary artery bypass grafting (CABG), suggest exacerbation of hypotension (low blood pressure) in patients who continued taking ACEI's or ARB's on the morning of their procedure. In addition, cases of low blood pressure (BP) that were refractory to standard treatment were reported. One recent retrospective study reported no difference in severe hypotension and only a modest difference in moderate hypotension managed by conventional treatment, but did not adequately address the risk of preoperative hypertension. A study recently published by the investigators (Twersky et al., 2014) in over 600 patients demonstrated no difference in preoperative hypertension in ambulatory surgery and same day admission patients. There has been limited data stratifying the degree of low BP based on severity but these were not done in ambulatory patients, and neither was the degree of high BP from discontinuing these medications addressed. As such, no uniform consensus has been reached and clinicians are unclear as to whether the reported inpatient findings are applicable to the outpatients, since they differ in many respects. The investigators propose to evaluate whether ACEI's and ARB's discontinued preoperatively have a negative impact on perioperative hemodynamics and patient outcome in a group of ambulatory and same day surgical patients. Similar to studies done on inpatients, the investigators will also evaluate patients receiving a standardized general anesthetic for hemodynamics following induction of anesthesia until surgical incision. The investigators hypothesize that continuing ACEI's and ARB's in the preoperative period does not result in an increased risk of severe hypotension (low blood pressure) following induction of general anesthesia.

NCT ID: NCT02993458 Terminated - Blood High Pressure Clinical Trials

DASH-Sodium Trial in Adolescents

CampDASH
Start date: October 2016
Phase: N/A
Study type: Interventional

The Camp DASH study trial will compare the effect of two dietary patterns and two levels of sodium intake on blood pressure and blood lipids in adolescents in the upper third of distribution for blood pressure. The two dietary patterns are based on the Dietary Approaches to Stop Hypertension (DASH) trial in adults.

NCT ID: NCT02929407 Terminated - Portal Hypertension Clinical Trials

A Study to Investigate the Effect of the Study Drug (FE 204205) in Patients With Cirrhotic Portal Hypertension

Start date: November 2016
Phase: Phase 1
Study type: Interventional

The purpose of this trial is to investigate safety, tolerability, pharmacodynamics, and pharmacokinetics after intravenous administration of FE 204205 in patients with cirrhotic portal hypertension.

NCT ID: NCT02608242 Terminated - Hypertension Clinical Trials

PK Study of YH22189 FDC Compared to Combination of Telmisartan/Amlodipine and Rosuvastatin

Start date: November 2015
Phase: Phase 1
Study type: Interventional

This is a Randomized, open-label, single-dose, 3-treatment, 3-period, 3-sequence crossover design.

NCT ID: NCT02304705 Terminated - Clinical trials for Heart Failure With Reactive Pulmonary Hypertension

Sildenafil in Heart Failure With Reactive Pulmonary Hypertension

Sildenafil-HF
Start date: January 2015
Phase: Phase 4
Study type: Interventional

The purpose of this study is to determine whether Sildenafil 20mg taken three times a day is effective in the treatment of Heart Failure with Reactive Pulmonary Hypertension. This is a double-blind, placebo controlled trial.

NCT ID: NCT02303834 Terminated - Hypertension Clinical Trials

CPAP in Preeclampsia

Start date: February 2015
Phase: N/A
Study type: Interventional

Study design: Single blinded randomised control trial Planned sample size: 30 (women randomized 2:1 to receive either CPAP or no CPAP) Objectives: Primary objective: Assess the effects of nasal CPAP on sleep physiology, 24 blood pressures and fetal movements in pregnant women (24-37 weeks gestation) with preeclampsia. Secondary objective: Assess baseline sleep physiology, blood pressure control and fetal well-being in pregnant women (24-37 weeks gestation) with preeclampsia by completing sleep studies, 24 hour blood pressure monitors, CO2 monitors, and nocturnal fetal movement and HR monitors. Study Procedure: Participants will be recruited from the antenatal ward or high-risk antenatal clinic. Following informed consent participants will be randomly assigned to receive either CPAP or no CPAP for one night, following an initial baseline overnight sleep study. Baseline- Night 1 1. Sleep study with fetal movement and HR monitor 2. 24 hour BP monitor 3. CO2 monitor Intervention- Night 2 (Nasal CPAP device or no CPAP) 1. Sleep study with fetal movement and HR monitor 2. 24 hour BP monitor 3. CO2 monitor Post-partum questionnaire A brief questionnaire to be completed within the first 6 weeks post-partum related to the participant's personal health, their child's birth details and health.

NCT ID: NCT02259634 Terminated - Hypertension Clinical Trials

Study on the Impact of Patient Navigators on the Health Education and Quality of Life in Formerly Incarcerated Patients

Start date: June 2014
Phase: N/A
Study type: Interventional

This is a 3-year prospective randomized comparative study of the efficacy of patient navigation on health education, health related quality of life, healthcare utilization, and medical outcomes in formerly incarcerated individuals. Individuals will be randomized to the patient-navigator intervention or to a care-as-usual control condition. A total of 300 recently incarcerated individuals will be enrolled with 150 subjects each in the intervention and usual care group. The investigators hypothesize that the intervention will improve health education, health related quality of life, adherence to clinical appointments, glycemic/blood pressure control, and virologic suppression in HIV-infected. The results of this study will demonstrate interventions to eliminate health disparities in a highly marginalized group going through the transitional phase of re-entry into the community.

NCT ID: NCT02250495 Terminated - Hypertension Clinical Trials

The Sympara VIBE Study for Hypertension

VIBE
Start date: October 2014
Phase: Phase 1/Phase 2
Study type: Interventional

The purpose of the VIBE study is to evaluate the efficacy and safety of the Sympara Therapeutic System in the treatment of hypertension

NCT ID: NCT02246348 Terminated - Clinical trials for Pulmonary Hypertension

Evaluating Lung Doppler Signals in Patients With Systemic Sclerosis (SSc)

Start date: September 2014
Phase: N/A
Study type: Interventional

Doppler signals can be recorded from the lung parenchyma by means of a pulsed Doppler ultrasound system incorporating a special signal processing package; i.e. the transthoracic parametric Doppler (TPD) (EchoSense Ltd., Haifa, Israel). Systemic sclerosis patients often develop pulmonary vascular disease leading to pulmonary hypertension. The TPD system may provide important insight into pulmonary blood vessels characteristics by the LDS signals that are related to pulmonary hypertension. The TPD performance in detecting PAH in SSc patients will be assessed in the study.
