Active clinical trials for "Hypertension, Pulmonary"

The goal of this clinical trial is to learn whether semaglutide, an FDA-approved treatment for diabetes and obesity, is feasible and tolerable in patients with advanced lung disease. The main question[s] it aims to answer are: Are patients with advanced lung disease able to tolerate semaglutide therapy? Are we able to titrate semaglutide therapy to a target weight? Participants will be asked to perform pulmonary function, physical function and body composition testing, as well as a blood draw before and after 12-weeks of semaglutide therapy. While on therapy, subjects will be surveyed regarding any adverse events or side effects.

This aim of the study is to evaluate the effect of nebulized nitroglycerin on echocardiographic (biventricular function, pulmonary artery pressure, PDA and PFO shunting and tissue doppler imaging) and clinical parameters (Oxygen saturation index, heart rate, blood pressure, mean airway pressure, ventilation setting) in patients with PPHN.

In this prospective study, the investigators will implement a systematic assessment of adherence to diuretics in a cohort of patients with precapillary pulmonary hypertension. This study is designed to: determine the overall adherence rates for diuretic regimen determine the determinants of non-adherence to diuretics assess the risk of PH worsening occurrence in the non-adhesion group

The six-minute walk test (6MWT) is a standard method for measuring exercise capacity in patients with cardiopulmonary disease such as pulmonary hypertension (PAH) and measures how far a patient can walk in 6 minutes. The test is usually performed in the hospital, by walking along a hospital corridor. Since the outbreak of SARS-CoV-2, there has been a need to minimise patient contact with hospitals and their staff to reduce transmission of the virus. In a previous research project called 6APP, the investigators designed, developed and evaluated a mobile phone app, to allow them to perform the 6MWT in the community. Given the current circumstances, cardiovascular outpatients including patients in the PAH clinic at Oxford University Hospitals are being recommended to use an app derived from that project to provide their 6MWT distance to the clinical team for assessment, in addition to their symptoms and general well-being. This is felt to be more appealing to the patients, and would reduce the time spent in hospital on the day of their outpatient appointment. The investigators plan to measure the usefulness of adopting remote, mobile-based 6MWT among hospital outpatients, within the constraints imposed by the SARS-COV2 pandemic.

This research study is being done to find out if exercise therapy can help improve the heart function, overall health, and quality of life of patients with pulmonary hypertension caused by heart failure.

Investigators plan to recruit 50 PAH patients from UofL PAH Clinic, with various degrees of severity (25 intermediate risk patients and 20 high risk patients) and 10 age and gender matched controls. PAH patients are evaluated at least every 6 months by the PAH Clinic and blood/urine samples will be obtained at each office visit. Blood, plasma and urine samples will be used to measure 31 metal levels including heavy metals (cadmium, arsenic, cobalt, lead etc.) and essential metals (calcium, copper, iron, zinc, potassium etc.) by the with ICP-MS via the service of ITEMFC. Interactions among the 31 metals in PAH patients, metal concentration differences between intermediate risk PAH, high risk PAH and control groups, the correlation between metal concentrations and the etiology, severity, duration, treatment, and progression of PAH/RV dysfunction over 12 months will be analyzed by CIEHS Biostatistics and Informatics Facility Core.

This study is a parallel group, single blind, randomized controlled trial. Patients with pulmonary hypertension who met the inclusion criteria and planned to undergo elective cardiac surgery under cardiopulmonary bypass from July 1, 2022 to December 1, 2024 in the Department of cardiac surgery of the First Affiliated Hospital of Shandong First Medical University were selected. After removing the aortic blocking forceps, the experimental group immediately injected the test drug (pituitrin 0.04u/ (kg · h)) intravenously, The control group was immediately injected with the corresponding dose of normal saline by intravenous pump. The main outcome was the composite endpoint of all-cause mortality 30 days after operation or common complications after cardiac surgery (stroke, requiring mechanical ventilation for more than 48 hours, deep sternal wound infection, cardiac reoperation, extracorporeal membrane oxygenation, atrial fibrillation or acute renal injury).

The goal of this pilot study is to evaluate the safety and efficacy of pulmonary artery denervation (PADN) in combined post- and pre- capillary pulmonary hypertension (CpcPH) associated with chronic heart failure(CHF). Participants who have received guideline-directed medical therapy (GDMT) according to 2022 AHA/ACC Guidelines for Heart Failure (HF) and have been clinically stable for at least 1 month, will be treated with PADN and followed for 1 year.

Chronic thromboembolic pulmonary hypertension (CTEPH) is a rare and potentially life-threatening progressive disease that evolves from unresolved pulmonary embolism. Gold standard treatment for CTEPH is pulmonary endarterectomy (PEA) performed by skilled cardio-thoracic surgeons. Some patients may not be surgical candidates due to co-morbidities or because the vascular lesions are too distal making them technically inoperable. In these patients, balloon pulmonary angioplasty (BPA) has emerged as an effective treatment. In a subgroup of patients, the distribution of vascular lesions makes it possible to perform either BPA or PEA. There has never been a head-to head comparison of BPA with PEA. The aim of this study is therefore, to evaluate if BPA is non-inferior to PEA in patients with (CTEPH) who are eligible for both treatments.

The purpose of this study is to evaluate the safety and explore the PK/PD of L-CIT supplementation in preterm infants to prevent the development of inflammatory pathways initiated by low levels of plasma CIT, specifically in preterm infants with post surgical NEC and BPD±PH.
