Active clinical trials for "Hypertension, Pulmonary"

Pulmonary hypertension (PHT) patients often receive long term oral anticoagulants. If the indication is strong, in the secondary chronic thrombo-embolism pulmonary hypertension (CTE-PHT) prevention, the frequent prescription (50 to 90% of patients) contrasts with their low level of proof in the PHT. Last but not least, anticoagulants are known to be the principal cause of iatrogenic hospitalization (major bleeding). In this study, patients are all followed during one year, to determine the annual frequency of major bleedings (according to the International Society on Thrombosis and Haemostasis (ISTH) international definition). Each event notified is validated by an independent committee for clinical events.

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.

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.

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

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.

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.

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 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.

Pulmonary arterial hypertension (PAH) is a serious, progressive disease that causes pulmonary arterial pressure, significantly affecting functional capacity and quality of life. Over the last few years, knowledge in pulmonary hypertension has evolved consistently and significantly. New diagnostic and treatment algorithms were combined based on the results of several clinical studies that showed the usefulness of new tools, as well as the effectiveness of new drugs as well as non-pharmacological treatment. The new guidelines felt the benefits of physical exercise in individuals with PAH, with promising results in improving symptoms, exercise capacity, peripheral muscle function and quality of life. With the COVID 19 pandemic, the complex scenario was for world health, and social distancing made it impossible to carry out individual outpatient rehabilitation, in groups and in person, indicating the need for rehabilitation programs, including physical training, to be adapted to the domicile. New alternative modes of pulmonary rehabilitation include home-based models and the use of telehealth. Telerehabilitation is the provision of rehabilitation services at a distance, using information and communication technologies. To date, there has been no evaluation of the clinical efficacy or safety of telerehabilitation in the population affected by PAH.
